The original trinity consisted of Maria (30) who was straight and went on her first cruise with her sister after her boyfriend dumped her. Maria’s younger sister Tina (28) is a confirmed lesbian top. On the cruise (chapters 1-5) they hooked up with Donna (nearing 40) who was a singer on the ship, and they believed her to be another female lesbian top, when in fact, she is a well-hung shemale.

At the end of chapter 5, the cruise ended, and Tina and Maria moved in together while Donna and Sherrie went to the USA to try to make it as a couple. (You will have to read it to find out more.)

I loved the characters so much that even before I had completed the story, I had started chapter 6 which was a reunion of the trinity in slightly more seedier surroundings. (If you have been to the Reeperbahn then you will know what I mean.) It was here that we met Otto for the first time.

Of course, my mind turned to where it always turns, and chapter 7 was born and 90% written before I had completed chapter 6. I needed to replace Donna with a more ‘suitable’ character for my favourite genre and who better than a three-year-old Rottweiler called Hans?

PS I couldn’t resist, so you may recognise some of the characters from Always Pull Your Curtains.

*****

“Who was that?” Tina asked her sister as she clicked off the phone after nearly 30 minutes of a one-sided conversation, where the caller did most of the talking. Throwing off the covers she pouted, “Are you coming back to bed? This pussy isn’t going to lick itself.”

“That was Otto, ” Maria said ignoring her sister’s offer, “he wants to know if we will do a private party for him and some friends.”

“We can’t. The Trinity isn’t complete. Donna is off in the Far East, no doubt making the lady boys in Thailand cry when she shows them her package.”

“He knows, which is why he has offered a replacement, ”

Maria turned her phone to her sister to show a picture of the replacement that had been sent through. Tina gasped with shock as she saw herself looking at a fierce-looking Rottweiler. What was shocking about the picture was the huge angry red cock hanging down under its belly.

“Fuck a dog?” Tina exclaimed, “Did you tell him to fuck off?” When Maria didn’t reply straight away, she went on, “You wouldn’t... would you?”

“Well, he did make an interesting offer, ” Maria said with an embarrassed smile.

“But it’s a dog, ” Tina said.

Maria was silently pacing their bedroom deep in thought.

“OK, ” said Tina finally, “let’s just talk this through so you can see how stupid an idea it is.”

Maria nodded as Tina fired her questions at her.

“Where is this going to happen, so the police won’t burst in?”

“Private river boat, anchored just where the Rhine goes into the Black Sea.”

“What if the dog bites you?”

“This dog is well trained, and it has fucked countless women before.”

“The guests taking pictures or videos?”

“All the guests are vetted and will be searched on entering and all recording or transmitting devices will be confiscated. There will only be one official video made of the event.”

“Ahah, ” exclaimed Tina, “our faces all over the internet, can’t see your boss liking that...or then again maybe he will.”

“Masks that will conceal our identities.”

“What do you mean our identities?”

“His plan is we are caught playing with each other when the dog surprises us and takes us both. He did say it would be good if we could struggle a bit.”

“You want me to be fucked by a dog? It’s bad enough you are even considering it, but even thinking I might be involved...” Tina frothed, “... you do remember I am a lesbian; you know, l...e...s...b...i...a...n?” she said spelling it out.

“You have always said it’s not that you don’t like cock it’s what it’s attached to you have a problem with...and...well... you do like dogs.”

Tina just stared at her sister open-mouthed with no sound coming out.

“Anyway, ” Maria said, “the offer is 50, 000 euros plus expenses.”

Tina stopped and Maria could see her brain working, “all expenses paid?”

“Yes, ” nodded Maria.

“That’s about £20, 000 each, ” Tina laughed.

“No, no, ” Maria said looking at her sister with glee, “that’s 50, 000 euros each.”

“What if we... you know... don’t like it, ” Tina said knowing that for that amount of money, she would try most things. “Let’s say halfway through we both refuse to go on, can’t see him paying us.”

“Good point and I was thinking about that when I was talking to Otto. Do you remember that Hayley woman we met on the cruise, who used to have kennels in the woods somewhere near here before she moved to a ranch in America?”

“Yes, ” said Tina as Maria went on,

“She hinted about a friend who owned an island that catered for ‘exotic’ tastes. Surely she must know someone.”

The only contact detail they had was an email address and wanting to be discrete sent a message that referred back to the cruise when they first met. At the end of the email, they mentioned that they were considering an ‘exotic’ holiday and whether she could recommend anywhere. They went on to say that although they liked the idea of ‘exotic’ they weren’t sure at this stage if it would suit them.

The return email was very chatty and remarked how she and her husband had enjoyed their company. Right at the end, almost as an afterthought she had put, “re the holiday, how long for?”

The sisters considered their reply and replied with, “At this stage, something short-term local would be ideal, perhaps a taster of different things.”

The response was very short, ‘leave it with me.’

*****

Over the next few days, both of the sisters contemplated the offer. Yes, it was a lot of money but at the same time, they would be doing something illegal and what most would consider immoral.

They started searching the internet, reading about dog sex and watching clips.

“Would you really do that?” Tina asked her sister as they watched a clip of a woman being fucked by a dog. When she turned to look at her sister, she knew the answer before she finished the question by the glazed look on her face, and the fact she was masturbating.

Maria fended off Otto’s messages about the offer with the response they were considering it. She was shocked when she received a message that said, ‘10, 000 euro bonus if you can make 20th April.”

To buy time she went back with, ‘Each?’

It took just a few seconds for Otto to reply, ‘Of course, but we must start plans by the 6th.”

Maria looked at the diary and realised they had less than two weeks.

It was Tuesday morning and Tina and Maria’s phones pinged with a message at exactly the same time. When they read the message, it was an address of local newsagents with a time later that day and signed off with, “Our mutual friend in USA sends her regards.”

They thought it strange that as they hadn’t given out their numbers how they were known but didn’t have time to consider further.

At the designated time they went to the newsagents who said nothing but nodded to a curtained-off door. Following instructions, they opened it and went down the stairs to be greeted by a small man with a moustache who was flanked by two massive blonde giants.

“Your phones, ” he said waving his hand to the desk.

The sisters put their phones on the desk and then the two blonde giants ran wands over them that beeped gently with pulsating green lights. Only when they nodded to the small man did he smile and begin talking.

“My name does not matter, nor does yours for that matter. What matters is we have a mutual friend who has vouched for you. Please do not be concerned, we have vetted you thoroughly and if we had found anything...adverse in the search, we would not be sitting here.”

The two sisters relaxed a little as the man swiped through his tablet though neither was sure how they were going to bring up what they hoped ‘exotic’ meant.

“So you wish to fuck dogs?” He began chuckling to himself as their search history was known to him. “And is it to be both of you or just one of you?”

“Both, ” they replied in unison albeit shocked that he knew and was so blunt.

“Do you wish for a pair of dogs so you can be fucked side by side or just one dog who will fuck you in turn?”

“Umm, ” said Maria.

“Take turns, ” Tina said, “we want to support each other.”

“Do you have a breed in mind?”

Maria showed him the picture she had been sent and the man whistled softly.

“He is...how you say...forceful. I am guessing this is your first time.” Tina and Maria nodded nervously. The man smiled and smoothed his moustache with his fingertip, “May I suggest you start with one of our Labradors? A much gentler breed but will still give you the full experience.”

They nodded in unison as the man flicked through the diary muttering in French, “ahah, ” he exclaimed, “Perfect, how does this coming Friday sound? It will be with Billy, such a lovely dog, great temperament and quite well hung.” He turned the tablet around to show an Indian woman crouched next to a yellow Labrador, its cock lying on her open palm.

The two women were stunned, it was like picking out a new outfit or choosing furniture yet it all seemed so ‘normal’ even though they were arranging for both of them to have dog sex in four days’ time.

“What about the cost?” Maria asked wondering if her credit card limit would be sufficient to meet the bill. Then immediately she wondered if they would even take a credit card. She nearly started giggling when she considered how it would appear on the bill... perhaps ’dog fucking fee’.

“Cost, ” chuckled the small man, “the first time is always free as we tend to find, how shall I put it? We tend to get a lot of repeat business.”

The two women looked at each other in disbelief as the man concluded, “You will be collected at 9 o’clock in the morning from your home. I am afraid you will have to wear hoods until you arrive at your destination. Please do not bring your phones, as they are not allowed. If you desire a video of your day we will happily provide you access to a secure server next week.”

That was it, the interview was over and the man stood and left by a different door to the one where the women had entered. The sisters left and got into the car that Tina drove. During the first part of the journey, they were both silent as they contemplated what they were about to do, then Tina broke the silence with, “Will you go first sis?”

“Yes but why?”

“You have a lot more experience with cocks than I do, apart from Donna’s this will only be my second one.”

Maria nodded and then started giggling.

“What’s so amusing? You know I don’t do cock.”

“It’s not, ” Maria said, “it’s just that by 19th April you will have had more dog cocks in you than human ones.”

Tina pouted and then burst into laughter.

*****

“Have you decided on the order?” asked the pleasant young woman who had introduced herself as Lena as she showed them into the small but lavishly appointed cottage. There was a small kitchen area with a large well-stocked fridge, including dog food and a bathroom with both a huge shower and sunken bath. Lena mentioned that they preferred it if the dog didn’t join them in the bath and showed them where the dog could go outside for his toilet needs.

“I will go first, ” Maria said with more confidence than she felt.

Lena nodded as she led them to the main seating area which was a collection of remarkably comfortable bean bags.

“Billy will be here in a minute, ” Lena said. “As it is your first time his handler Rula will remain with you and will guide you. This may involve touching which I take it you are both OK with.” The sisters nodded as Lena went on, “Billy is fully trained, but you must remember with dogs that if you are aggressive to them, it will confuse them and they may not respond as you wish. Keep in your head that they are in charge as you are their bitch. Praise is paramount in whatever they do.”

Lena could sense that the two women were still very nervous and to calm them she said, “Why don’t you both take off your clothes and relax? Are you... ummm... close as sisters?”

“I taught her how to lick pussy... my pussy, ” Tina laughed.

“Well maybe you can judge my technique later, ” Lena said moving to the door as she had heard the van arrive with Billy.

Billy bounded into the room, happy with life and greeted Lena enthusiastically who made a big fuss of him.

“Who is a gorgeous boy then?” she said ruffling his head, “Have you come to claim your two new bitches?”

‘Bitches’ may have been a keyword or just a coincidence but Billy stopped and regarded Tina and Maria intently. Lena and Rula exchanged a few words in their own language and Maria heard her name mentioned. Rula smiled at Maria before she crouched down and reached under Billy to work his cock that was already out of its sheath.

“You are first, ” she nodded to Maria, “please help me with his cock. I stay dressed or he will think me his bitch.” Then she giggled, “As I will be for the rest of the night after you both leave.”

Maria reached under Billy who stood stock still, and took the dog’s cock in her hand. It struck her how warm it was and she could feel it still swelling as she gently worked it, covering her in the fluid that was constantly dripping from the dog.

“Now he must taste his bitch, ” Rula said and reached under Maria and pushed two fingers into her wetness. “Good, ” she smiled, “you are eager for him.” Then she withdrew her fingers before holding them to Billy’s nose. The dog sniffed and then licked them eagerly. The dog sniffed the air and locating the source burrowed his head between Maria’s thighs.

Maria fell onto her back and Billy started to lick enthusiastically sending Maria wild.

“Oh, my fucking god, ” she screamed arching off the bed and thrusting her groin towards the dog’s tongue.

“Does it feel good?” panted Tina who was watching her sister intently.

“Out of this worldddddd, ” Maria groaned as she started to orgasm from the rough pink tongue darting inside, licking every part of her insides.

“Better than me?” Tina asked.

“Hell Yessssss, ” Maria yelled as she came on the dog’s tongue yet again.

Rula was an expert at judging when the time was right, as she and Billy had broken in many virgins, or certainly virgins to dog cock. She could see that Billy was fully out and the woman was certainly ready.

“Roll onto your hands and knees, ” Rula said as she pulled Billy away. Maria complied quickly and Rula added, “Keep your back level until he is in, then it won’t matter.” She didn’t bother adding that if she got the position wrong there was the danger of anal. As neither had indicated on the questionnaire they wanted that on this occasion, she wanted to make sure accidents didn’t happen.

Maria could feel Billy on her back and the thrust of his cock as his paws gripped her waist. She felt the roughness of the pads of his paws but not scratches as his claws were carefully clipped and his dew claws removed. She could feel Rula’s hand guiding Billy expertly to her pussy and then her world went mad.

Tina watched the dog dancing as it thrust and the Rula guided the dog’s cock to her sister’s pussy. As the dog thrust in, the noise that came from Maria’s mouth was the hottest thing she had ever heard.

Rula looked at Tina, her eyes bright, “Dog virgin no more, you next.”

Tina was scared yet more excited than she had ever been in her life. She watched her sister brace her head against her folded arms as the dog fucked her at a pace she wouldn’t have believed was possible. The noises coming from her sister weren’t human or comprehensible as the red cock slammed in and out, making her breasts wobble at a tremendous pace.

Maria was in heaven as the dog fucked her at high speed, making her cum over and over. She could feel the knot banging against her pussy lips, something she had read about, so she started breathing deeply to grant it access. She realised that the dog didn’t care whether she wanted it or not, the knot was going in regardless. There was a momentary flash of pain and then her pussy clamped around as it swelled to lock in. For a moment nothing happened, like time was standing still and then it pulsed deep inside followed by a jet of hot fluid. Further pulses gave further jets, and the sensations were exquisite. Maria knew she was now hooked on dog cock.

“She is knotted, this is good, ” Rula said nodding but Tina said nothing as she was transfixed by her sister’s face. It was akin to someone who was enjoying an epiphany with sheer bliss written into every pore. Billy lay on Maria’s back, his tongue hanging from his mouth as he panted happily, his knot pumping seed into his new bitch.

“How are you feeling?” Rula said gently to Tina as they both watched Maria and Billy locked together.

“Nervous, ” Tina swallowed.

“You are lesbian yes?” Rula said as Tina nodded. “I too prefer women with humans but love my Billy so much. It is so different. You will still be lesbian afterwards, but you will love dogs even more.”

“It’s normally me who does the fucking, ” Tina said, “so this is something very, very different.”

“Are you a virgin?” Rula asked, the concern clear in her voice.

Tina shook her head, “No I have had one cock before, she was a good friend.”

Rula raised an eyebrow at the mixed-gender reference but didn’t comment and carried on like it was totally normal. “Your friend was she big?” Tina nodded as Rula went on, “Did you cum?”

Tina blushed as she replied, “Yes... a lot.”

“Is good, Billy will do all the work, you just brace and cum a lot.” Then looking at Billy who was restless she went on, “Now I must make sure Billy is ready for you... do you suck cock?” When she saw the look of horror on Tina’s face she laughed, “No worry. I love sucking his cock, now attend to your sister, I will need 15 minutes.”

Rula reached under Maria and massaged her lower belly and pubic region until Billy pulled free with a loud plop. Maria collapsed onto her front as Rula made a fuss of Billy while still working his cock. Every so often she would bend her head and suck his cock as he panted happily.

Tina lay next to her sister and stroked her head gently as she mumbled happily still floating on an orgasmic cloud. She had seen her sister in a post-coital stupor previously, and knew she would get little sense from her for a while. Then she heard Rula say, “Tina he is ready.”

Maria lifted her head and said hoarsely, “Enjoy.”

Tina went to kneel like her sister but Rula said, “No tongue first, ”

“I have been licked many times before.”

“Not by a dog, it is very different, trust me.”

Tina remembered how her sister had reacted so decided to go with the flow. “Will you lick me first?” She laughed.

“Yes I will, ” said Rula, “but you will need to keep Billy aroused with your hand or mouth.”

Tina was in a quandary as she lay on her back but then felt Rula slip two slender fingers into her wetness. She was an expert at pleasing women as she twisted her fingers to locate Tina’s g-spot and started to massage it with her fingertips.

“Do not forget Billy, ” Rula reminded her, before bending her head and began licking Tina, making her groan.

Tina gripped Billy’s cock and could feel the cock warm in her hand as she worked the shaft. Billy was restless as he kept moving and changing his position, shuffling his cock closer to Tina’s face. Rula could see what was happening, exactly as she thought it would. Some dogs don’t like being sucked but Billy was different. He was spoilt as Rula sucked his cock 2 or 3 times a day, so it had become something he was very used to and enjoyed. Sucking Tina’s clit between her lips Rula pressed making Tina open her mouth and groan. At that moment Billy moved forward and Tina found herself doing something she never thought she would do, she started sucking a dog cock.

Her orgasm wasn’t far away as Rula’s talented tongue and fingers forced her over the edge. As she writhed in pleasure, it seemed the most natural thing in the world to suck on Billy’s cock. She felt Billy being moved away and looked up at Rula’s smiling face.

“That was amazing, ” Tina gasped.

“The best is yet to come, ” Rula said as she licked a trickle of pre-cum from Tina’s cheek.

Tina lay back half in shock at what she had just done. Running her tongue over her lips she could taste the seed of the cock she had just sucked. She couldn’t imagine the dog would lick that much better. Immediately her opinion changed... forever.

It was like someone had taken a warm pad of sandpaper and run it through her pussy lips and over her clit. Before her brain had a chance to process what she was feeling, it happened again and again. Had she not wanted to orgasm she knew deep down she would have anyway, such were the sensations that burst through her brain. She would have put Rula’s licking high on the list of amazing oral experiences, but that paled into insignificance compared to Billy’s tongue. She could feel it delving inside, far further than the most talented lickers she had ever entertained. It was powerful, flexible, earth-shatteringly amazing, it was truly perfect.

“I told you it was good, didn’t I?” Rula whispered close to her ear. “Are you ready for him to fuck you now?”

“Noooo, ” whimpered Tina, “let him lick me some more.”

“You sucked his cock like a bitch, cum on his tongue like a bitch, now you must become his bitch. It is time.”

Tina rolled onto all fours, blood pumping in her ears as she yelled, “Fuck me and make me your bitch.”

Maria had recovered enough to have witnessed her sister sucking the dog’s cock and cum on its tongue and now saw Rula helping Billy mount Tina. She watched as the red cock she had so recently enjoyed slammed into Tina, not so much taking her to orgasm but keeping her on a climactic plateau.

“May I?” She heard Rula ask, as she knelt between her legs.

“Be my guest, ” Maria said opening her legs wider allowing Rula to lick her clean.

After cleaning Maria of Billy’s seed and bringing her to orgasm at the same time, Rula moved over to Tina and Billy. She ruffled Billy’s head affectionately as he pumped his seed into a mewing Tina via his pulsing knot. Wriggling under she waited until he tugged away before clamping her mouth over Tina’s pussy and sucking out Billy’s seed. With the two women lying in orgasmic euphoria, Rula efficiently cleaned Billy’s cock with her mouth before it vanished back into its furry sheath.

“Time for you to rest my love, tonight your bitch needs you.”

After Rula had left with Billy, the two sisters lay in the big sunken bath facing each other. Rula had said they would be run home as soon as they were ready but there was no rush. When Maria had asked how they would let someone know, Rula just smiled and pointed to the discrete cameras dotted about, “They will know, ” she laughed.

Tina had collected a bottle of champagne from the fridge and as they sipped Tina said, “Well?”

“It was every bit as good as I thought it would be and a lot more, ” Maria smiled, “what about for you?”

“Mind-blowing, ” Tina said, “if men fucked like that, I would stop being a lesbian. I understand why those women in the clips cum so much, I know I did.”

“So do I tell Otto yes?”

“Damn right you do, ” Tina laughed.

*****

“We fly to Germany via Switzerland, ” Otto said as they settled into the first-class seats. Once they arrived in Geneva, they were ushered into a black limousine that took them to a plain building with a tiny highly polished brass plate on the door. Maria managed to make out the word ‘bank’ before they were escorted through to an office where they were greeted by a smartly dressed young man.

“I understand you wish to open an account, ” he said softly, “we wouldn’t normally do this for such a small amount but have agreed on the strength of your introduction.”

“Do you need our passports?” Maria said reaching into her bag.

The man threw up his hands in horror, “ No, no, if I see your passport then I become bound by the banking laws of whatever country you reside in. If I see your names then I become honour-bound to report you if you contravene them.” He smiled before he continued, “Of course, if we are ignorant of such facts then we have not transgressed any laws. You may give us first names to be addressed by if you wish.”

The sisters looked at each other and giggled.

“Cupid, ” said Maria.

“Blitzen, ” said Tina.

Both of them had given their stage names for the sex show in Hamburg at the end of the previous year. The man was totally unfazed by the names and giving a small cough began.

“Well, Miss Cupid and Miss Blitzen allow me to explain.”

Over the next 10 minutes, he went into great detail about how the account would operate and what services they could offer. Their faces were scanned and DNA samples were taken. They were allocated an account number and had to create a 16-digit pass ode. The man stressed that the code allowed full access to the account, so it was vital it was kept secret. If they made three error attempts then the account would be locked and only their personal appearance could reset the account.

In less than an hour they were back in the car with a beaming Otto.

“Excellent, do you have an account number?”

While they drove back to the airport he handed them a carrier bag which contained a cuckoo clock and some chocolate. Before they could question him on the strange gifts, his phone pinged and he smiled reading the message.

“The money, with bonus, is in your account.” Seeing their faces at the carrier bag he laughed, “Should anyone ever ask what is your reason for visiting Switzerland. Now we must hurry as we have a plane to catch and you have a dog to fuck.”

*****

When Otto had said they would be on a small river boat, the two girls had in mind the houseboats they used to go on in the Norfolk broads when they were children. Neither of them had expected what looked like a mini-cruise ship.

Originally the river boat accommodated nearly 200 guests in 100 cabins travelling up and down the Rhine. The company collapsed during the COVID pandemic and Otto had snapped up the boat and made extensive alterations, the main one was increasing the size of the cabins considerably. Now the lower guest floor had just 12 suites with a well-equipped kitchen serving a luxurious dining room in the centre. The upper floor was the same with another 12 suites but in the centre was a lounge come bar with a central stage.

The one shock that had been sprung on them on the short plane ride was that the audience all spoke English, so there would be no narrator. The pair then put their heads together as they formulated a rough storyline. After a while, they agreed the plan seemed plausible but it needed Otto’s help. They explained his minimal involvement and after some discussion, he clapped his hands in delight, agreeing to the storyline.

They set sail and the guests were all served dinner while the girls checked out the stage. What did surprise them was instead of the wealthy European businessmen they had expected, the guests were all Arabs, most of whom were in traditional attire. After dinner, the audience took their seats in a horseshoe around the central stage, which was little more than a 3-metre round padded raised platform.

Tina and Maria entered from the open end of the horseshoe and stood on the platform.

“Good evening gentlemen, my name is Blitzen and this is my slut sister Cupid. I have been a lesbian all of my life and have recently converted my sister to the same. We will perform for you in a moment and then my sister the slut, will be fucked by a dog. We would ask you not to touch any of us during the performance, as the dog may bite you.”

Tina reached out and took the nipple chain between her finger and thumb and lifted it into the air. It hadn’t travelled far before it started to lift Maria’s breasts. Maria let out a soft moan as she lifted herself onto her tiptoes, her nipples extended as they were tugged by the teeth gripping her flesh. Tina slipped a hand between Maria’s legs and thrust two fingers in, finger fucking her fast. Then pulling out her fingers, she held them up like a magician producing a rabbit from a hat. She held them up to the audience so they could see they were covered in her juices. Holding them to Maria’s lips she didn’t need to give the command as Maria slowly and theatrically sucked them.

When they outlined the storyline on the plane, Otto argued for a prolonged lesbian scene.

Maria had countered with, “These guys can get lesbian scenes any time they want, the reason we are on a boat to nowhere is us fucking dogs. The sooner we get to that the happier they will be.”

“She does have a point you know, ” Tina laughed.

“Are you ready for the dog?” Tina said as she lifted Maria’s head by her hair so she could look her in the eyes. At that cue, Hans was led onto the stage to hushed murmurs from the crowd.

“Yes..., ” Maria had to bite back the word Mistress, “...sister. I want to feel it’s fat cock in my slutty cunt.”

“See he can smell you are ready to be his bitch.” Tina mock snarled. Her words were reinforced by the fact that Hans’s cock had emerged from its sheath and was already dripping steadily.

Maria moaned loudly, and it wasn’t just an act, dropping to all fours, ready to be mounted the way Billy did in the cottage.

“Suck him, show these good people what you are.”

Maria started to suck but Hans wasn’t happy and tried to fuck her mouth making her cough. As she pulled the cock to try to gather her breath Hans moved around behind her and mounted. He jabbed wildly and a couple of times Maria felt a sharp pain in her ass as he tried to penetrate her anal ring.

“No not my ass, he is too big.”

Tina just laughed, “If he wants your ass, he will take it and you will let him.”

Maria reached between her legs and guided him to her pussy where he sank in and immediately started fucking at speed. He was bigger and more brutal than Billy. This was a dog that wanted to fuck and was doing exactly that. Maria could feel herself cumming from the savage thrusts and remembered to start breathing deeply, to relax her enough to let him force his knot home.

It swelled quickly and Maria could feel her insides being moved around as he started to throb and pulses. When the first jet of red hot cum splashed against her cervix she screamed loudly, no fake orgasm but a genuine climax.

After he had pumped his fill, Hans started to tug away making Maria groan with discomfort. Then he tugged hard enough and left a spray of cum on the floor as he pulled free. Now that he had fully dismounted from Maria the audience could see her open and oozing pussy, her lips puffy and pink from the brutal fucking. The dog sat on its haunches in front of Maria, who dutifully leant forward and began to suck the dog, maintaining its arousal.

“You can see how much of a slut my sister is, not only does she let a dog fuck her, she eagerly sucks its cock before and now afterwards.”

“What about you?” shouted Otto from the audience.

“That’s not going to happen, ” Tina replied.

Hans had moved closer to Tina as Maria had stood with her hands on her hips and shouted, “You promised you would do it if I did, you lying bitch.”

Tina smirked arrogantly but Maria grabbed her by her hair, as they had arranged, and pulled her head to the floor so she was on all fours. To add to the drama Hans started to growl, as he was not sure what was happening.

“Mount, ” hissed Otto and on hearing his master’s command turned to the nearest bitch and jumped onto Tina’s back, jabbing wildly as he grabbed her hips.

“No stop, ” Tina shouted, “no male has ever been inside me.”

“That is about to change, ” Maria laughed as she reached under and guided Hans’s dripping red cock to her sister’s wetness.

“Please no!” Tina sobbed even though inside she was screaming yes as she had seen how much Maria had enjoyed it.

Hans didn’t care, the tip of his cock had found a hole and he thrust forward burying his cock deep into Tina’s pussy.

The first thing Tina noticed was he was considerably bigger than Billy and was also much more aggressive. She could feel his paws on her hips, pulling her back onto his cock that he was ramming in at high speed. Not happy with his position he moved to placing his front paws on Tina’s back, pushing her upper body onto the floor.

“Please no... please, ” Tina sobbed trying to hold back on letting her audience see her pleasure, as Hans almost raped her.

Lifting her head by her hair Maria snarled into her sister's face, “Tell these people what a dog slut you are now and how you love it in your cunt.”

“No, ” Tine yelled, then unable to hold back any longer started to orgasm onto Hans’s huge red member. The act of cumming allowed Hans to drive his cock fully home, including his knot that made Tina gasp with pleasure. As it swelled locking inside, his movements slowed until he lay on her back pumping his seed into her body.

“See how she cums, ” Maria laughed as Tina thrashed her head from side to side in orgasm.

*****

The two sisters lay naked on the bed in their cabin resting after their exertions with Hans. Tina was on her belly as Maria applied cream to the scratches on her back. There was a knock on the door and Maria opened it to see the beaming face of Otto. Maria left the door open so Otto could follow into the room and as he stood at the foot of the bed Maria lay next to her sister. Both women were naked but neither was concerned, after all, he had just seen them both fucked by a Rottweiler.

“You were fantastic, they all loved it. You were a star, Tina, they really thought you were fighting it. They loved it so much they would like the three of you to go to their countries and repeat your performance for different audiences.”
