"Oh my, I'm so full!" my mother belches out as she burps half way through, rubbing her swollen, cum filled belly. My sister Jenny and I both laugh as she does.
"Well we certainly are full" my sister replies "I can't think of how you did what you did brother but I'm not complaining, that was the best orgasm I've ever had in my life" as she crawls over to me, body dripping with sweat and cum "I wonder, what could possibly be the source of this new found wonder??"
I should have guessed something was up from the moment she crawled over to me, smiling, sexy as fuck and with a slightly mischievous look on her face. The next thing I knew, her hand reached up to my ear and yanked out the interface control.
"Hey, no!!" I screamed.
"Freeze" my sister spoke as I lost all memory from that point on.
"Huh" Jenny spoke.
"How did you do that?!" Sandra quizzed.
"Well, in all my years I've never, EVER been compelled to fuck my brother, never once felt that he was attractive, let alone felt the urge to do anything remotely erotic to him, yet now, on this day, for no apparent reason I suddenly desire him? It didn't make sense, and when we were kissing before you arrived out here I found myself kissing his neck and ears when I spotted it in his ear".
Sandra reached out for the earpiece and examined it.
"Huh" she responded. "Now that you mention it, it all makes sense, I mean, I felt compelled, like it was perfectly natural, but now I see whats happened.....oh my god, how long do you think your brother has been doing this to us?!"
Jenny took the earpiece back, "I don't know, but I do know this, I wanna have a little fun with this prick" she smiled. "what do you think mum? wanna have a little revenge fun on your son?" grinning from ear to ear as she stuffed the device in her own ear.
The device flashed up in her mind. New user detected - would you like to create a new profile or choose from an existing one. Jenny could see the options for created profiles and saw herself and her family. Glancing over, she appeared to be looking at her mother but was in fact looking at a heads up display in her mind.
"What.....what are you looking at me like that for dear??" Sandra asked her daughter inquisitively.
"Oh sorry mum I wasn't actually looking at you, there is an interface which apparently only I can see. We're all on here, Jenny spoke. "What do you mean we're all on here" her mother replied.
"US!, our family, all our stats, everything he has done, all the changes, why that little shit!" Jenny smiled as she began to get used to the device.
"Well, thankfully he has only been using this since yesterday so not too much damage has been done. Let me just select my profile and maybe I can clue you in to what I'm seeing" Jenny spoke as she selected her profile from the list, checking what changes her brother had made to her and their mother.
'Would you like to change from user account to admin?' the interface quizzed. Jenny smiled, oh the revenge she would have. 'Admin account created - would you like to create another?' Hell to the fucking yes Jenny thought.
As the interface began to analyse it's new host, it adjusted to Jenny's thoughts and preferences, as if learning what she would want before she did.
"Right, I've made you an admin too mum, you should be able to see what I see now" as her mother looked at Jenny, an image of the interface appeared in her mind. "Oh my word, oh my gosh, wow, oh you little pervert!" were some of the words that came to Sandra's mind. "I had no idea that all this was changed! I just assumed it had been this way all my life!". "I must say though, for a twisted little sod, the boy does have great taste, and I do approve of these nice new changes to our bodies" Sandra spoke as she admired her large breasts and firm ass.
"Watch this" Jenny grinned as she looked over to her brother. Suddenly his cock began to rise and shrink, over and over. It rose and shrank from several feet high to barely visible. When his cock was massive, Jenny joked "Hot" and then when it shrank, "cold" before repeating over and over, both laughing as they did.
"Oh stop it, you'll give your brother stretch marks!" Sandra grinned. "Look, obviously this is a very powerful device and we shouldn't mess around too much, we don't know what damage we could do"
"Not that he would have given that any mind" Jenny replied.
"It seems my son made changes to our bodies and minds but also had the intelligence to realise that it would have far reaching consequences to anyone who was not aware of the changes" her mother replied.
"Wow, maybe he's not such a sex driven idiot after all, at least he was trying I guess" Jenny mused. "Well, what shall we do first then?"
At that moment, the two women heard a "WHAT THE FUCK IS GOING ON HERE?!" as a rather angry husband and father stood over them both.
"SHIT! FREEZE!" Jenny almost screamed. As her father froze in place.
Sandra stood up, rushing over to her husband Rick. She stood for a moment, examining his frozen body. "So......he's frozen right, can't hear or understand us??" Sandra asked.
Jenny replied, "yeah, it seems to affect only the immediate area or person you are looking at when you freeze, might explain why dad found us here, shit what are we going to do mum?"
Sandra mused for a few moments before a smile stretched across her face. "Remember how you said you wanted to have some fun?"
"Ha, yeah, why, what have you got in mind mother?" as Jenny stood up and walked over, cum oozing out of her pussy as she waddled over.
"You know, your father is quite the man, I know you never thought of him this way before but seeing as he will never remember this, I would totally love to see him fuck you" Sandra grinned. Biting her lip as she did not know how her daughter would react.
"Well actually mother, I have often thought about dad fucking me, I just never thought it would happen" Jenny replied, biting her lip and giving her father the once up and down as she checked him out in full view of her mother. "Maybe.....hmmmmm, maybe if we made just, you know, a few changes?" Jenny smirked at her mother.
Sandra smiled, feeling a tangle in her pussy at her daughter's admittance that she found her father sexually attractive. "Great! help me get him out of these clothes, then we can have a bit of fun".
"Oh sod that" Jenny replied, "I'll just remove them with my mind!" As suddenly, her father was naked, clothes completely removed and his cock hanging low. "Holy fuck?! he's a fucking donkey!" Jenny gasped.
Sandra laughed. "Yes, yes he is, quite the man as I told you". Sandra began to walk around her naked husband before sliding her hand down his chest and down to his hanging cock. The changes Sandra made to her husband began to form as her hand roamed his body, tighter, firmer, more muscular, but not too much, just....toned.
"You know, your father is the only man I've ever been with, excluding your brother who has lets face it, effectively raped us. I remember the fist time he fucked me, I'd never seen such a big cock, let alone had one stuffed inside me. He was so clumsy when he first fucked me, taking my virginity, I thought I was going to pass out, and it hurt! Not just from the fact that he had taken my virginity, but the fact the his cock was constantly trying to fuck its way in to my womb!"
"Like father like son I guess" Jenny smiled.
"Oh no" Sandra laughed, your brother was never that big before, I mean, granted I hadn't seen it in a few years but your brother was probably average, maybe 5, 6 inches?? Not that it matters of course because a woman's vagina adjusts to the size of whatever manages to snake it's way inside".
Jenny's eyebrows raised. "Wow really? Huh, I never knew, I just assumed bigger was better"
Sandra began to stroke her husbands cock to life. "Oh it can be, but like they say, its not the size of it that counts, it's how you use it". And with that, Sandra swallowed her husbands cock in her mouth. "mmmmmmm" she moaned as she looked at her daughter as she sucked Ricks cock in her mouth, up and down, deeper and deeper each time until his full length was past her tonsils. Sandra knew her son had removed her gag reflex when he first made the changes to her and now, she was thankful. Sandra picked up the pace, grabbing her husbands ass and pulling his cock fully into her mouth as her neck stretched each time it slid down her throat.
A few minutes passed as Sandra deep throat-ed her husband, even managing to squeeze his balls in her mouth too, oh how he would be loving this right now if he was aware enough to know what was happening to him. Soon Sandra began to ease up before letting him out with a 'pop'.
"Gosh, all my years I never thought to do that, the idea of sucking something that they use to pee out of disgusted me, but now that I know I can make it taste of whatever I like, it's actually quite a turn on!" Sandra looked into Jenny's eyes, "Wanna try?" Grinning as she offered her husbands large cock to her daughter.
Jenny smiled nervously as she grasped her fathers large appendage, feeling its weight and girth as she brought it to her lips, looking loving at her mother as she closed her eyes and sucked his fat cock into her mouth.
Her mother rose like a proud parent, watching her daughter suck her father for the first time as his cock slid deeper and deeper into her throat.
Sandra leaned on her husband as she began to whisper new instructions to him before whispering "wake" into his ear.
Lost in the moment of sucking her fathers cock, Jenny was slightly taken aback when her fathers hands slid over her head before pulling her harder onto his cock. "That's it honey, suck daddy's big, fat cock, mmmmmmm yeah, just like that, deeper! mmmmmmmm ohhh god yes!" Rick groaned as he pulled his daughter onto his cock.
Jenny looked up to see her mother and father smiling down at her as she found her self effectively being face fucked now. "It's ok dear, I made a few changes, he's ok with everything now. Didn't want to have fun with a mindless drone, I've got a vibrator for that" Sandra grinned, watching as her husband forcing his massive cock down her neck, thrusting harder and harder now.
"Oh god babe, I've dream't of this moment, you and me, fucking our daughter together Oooooohhhh jesus this feels good!! Ohh god honey I'm gonna cum! I'm gonna cum in our daughters mouth!!
Rick strained and grunted hard as he felt his orgasm building, driving his cock to the hilt in his daughters throat while his wife urged him on.
"Do it baby, mmmmmm god this is turning me on, you have no idea how hot it is to see you fucking our daughters slutty mouth" Jenny gave a look of disapproval at her mother for calling her a slut. "Cum in her mouth baby, come on, fill our baby girls mouth with all your hot, wet, cum". As Sandra's tongue slid into her husbands ear, sucking and licking his ear lobe while her free hand squeezed his ass, urging him into her daughters mouth.
"Ohhhh god I'm gonna cum!" Rick screamed as he continued to pound Jenny's mouth, Sandra was now dry-humping her husbands leg as she watched, her pussy juices streaming down his leg.
"AAARRGHHHHHH!!! YESSS!!!" Rick screamed as he began to unload stream after stream of hot, sticky, sweet tasting cum into his daughters throat. Jenny was surprised at the taste, strawberry, just like the ice cream she loved so much. Jenny couldn't get enough, her belly was full and bursting with her brothers cum, but now she wanted more!
Ricks orgasm began to subside as he started to come down from blasting his hot seed into Jenny's mouth. Jenny licked and savoured her fathers cum as she looked into her parents eyes as they watched their talented daughter clean her father off. Jenny finished by opening her mouth to her mother and father, displaying what cum was left in her mouth before gleefully swallowing whole.
"Ohhh my god" Rick moaned as he smiled to his wife. "We definitely have a talented daughter honey".
Sandra smiled back, "We certainly do dear, we certainly do", as they began to kiss.
Jenny stood up, smiling at her father as both his wife and daughter stood naked next to him either side, covered in cum and bellies swollen like they were 9 months pregnant. Ricks cock began to shrink back down to a normal size again as he looked over to his son on the sun bed, butt naked and cock standing a few feet high and passed out.
"What on earth have you done to him?!" Rick quizzed smiling.
Sandra and Jenny both looked over and laughed. "Oh yeah, I forgot about him!" as they all laughed at their sibling.
"What are we going to do about him?" Jenny asked her mother inquiringly.
"I had a thought about that" Sandra replied.
"FREEZE"
