I had just finished mowing the lawn when the moving truck backed into the house next door.

My name is Mark. I am 18 years old. It was Friday, June 10th. I had finished the 11th grade in high school. Because my birthday is in late December, I could not enter first grade until I was almost seven. Like my dad, I am tall, 6 feet 4 inches. I am pretty muscular due to playing basketball, football and wrestling in high school. My Dad is the CEO of a steel fabricating plant outside Pensacola, Florida, so the summers are hot and humid. My mom is his secretary.

I was sweating pretty good when the truck arrived. A large Toyota Highlander pulled up in front of the house. The house has been vacant since April when the older couple retired and moved away.

A man stepped out of the driver’s door. He was about as tall as me, with light brown hair graying at the temples. His wife stepped out of the front passenger door. She was absolutely stunning with blonde hair and huge breasts. Next, two girls stepped out. They were obviously twins, also blonde and gorgeous. Like their parents, they were tall, about 5’11” with large breasts, similar to their mother.

I just stood there. I was all hot and sweaty from mowing. I wore a pair of cut-off jeans and no shirt. I realized we were all just looking at each other. I turned off the mower and walked over to introduce myself.

“Hi, my name is Mark. I see you have bought the Johnson’s house. Welcome to the neighborhood.”

The man stepped forward to shake my hand. I quickly rubbed my hand on my shorts before shaking his hand.

“Nice to meet you, Mark. My name is James Wilson. This is my wife, Alice and my daughters, Mariane and Margaret.”

His wife stepped up and shook my hand. Both daughters moved up beside me and looked up. They both smiled. “It’s very nice to meet you, ” they said, almost together.

I asked if they needed help unloading the truck, but they thanked me and said no. The two men in the truck took care of everything.

James asked me about my parents. When he found out where my dad worked, he smiled. That is an amazing coincidence! I am your dad’s new CFO and my wife, Susan, is my assistant.

Dad and mom got home about 6pm, their regular time. I told them about James. They immediately went over and introduced themselves. They invited them over for lunch tomorrow and enjoy their pool.

Saturday was sunny and warm in the mid 80’s. Mark, his dad and James were working the grill. Mark’s dog, Blackie, was lying in the sun, patiently waiting for his share of the food cooking on the grill. Blackie was a large mix of Italian Mastiff and Leonberger. He weighed about 150 pounds and was very friendly.

When the four women came outside, the men stopped what they were doing, stunned by the four gorgeous women in tiny bikinis. They were hardly more than tiny triangles barely covering nipples and completely shaved pussies. The wives, Alice and Susan, moved to their husbands while Mariane and Margaret slid up to both sides of Mark. They appreciated how his cock was straining the swim trunks. They each wrapped their hands around his muscular arms so their tits were pressed against his chest.

Mariane said, “Why don’t we jump in the pool before you rip a hole in your trunks?” Mark grinned and agreed. He and the twins jumped in the pool. Both girls reached down and rubbed the bulge in his trunks.

The girls told him they were glad he lived next door and was so tall and buffed. At their last school, they were taller than all the boys, who were intimidated by their height. Margaret said they were frustrated and horny, they had to just pleasure each other, since no boys were around.

Mark just smiled. “Why don’t you come around Monday? Our parents are at work all day, so we have all the time in the world to get better acquainted.” The girls quickly agreed.

Monday morning, Mark was up early and had breakfast with his parents. After they left, he went upstairs, got his razor and lather. He sat on the toilet and shaved his ten-inch cock and balls completely clean.

He and Blackie went outside to enjoy the warm weather. Mark never wore anything in his back yard. It was fenced in and completely private. He laid down on a lawn chair and thought about his new neighbors’ beautiful daughters. This made his cock quickly get very hard, so he started slowly stroking. Blackie came up and started licking Mark’s stomach and down to his legs and groin. Mark pulled his legs up close to his chest and continued stroking his cock, Blackie focused on licking Mark’s taint and asshole.

Mark did not realize Mariane and Margaret’s bedroom window overlooked his backyard. Both girls were watching the scene below. They were getting very aroused and excited. They removed their pajamas and started rubbing their wet pussies. That was not enough. Margaret laid down on her bed and Mariane laid on top of her in the 69 position and started licking each other’s pussy and asshole. It did not take them long to cum, squirting pussy juice all over their faces. They did not bother to wash up. They immediately ran downstairs, out the back door and crossed their yard, opening the gate between the two properties.

Mark heard the gate open and sat up, pushing Blackie away. When he saw the giggling girls, he walked over and gave them a big hug. The girls eagerly hugged him back, all three rubbing their hands all over each other’s bodies. Mark’s hands went from rubbing both sets of breasts and pinching their nipples down to stroking their very wet pussies. At the same time, the girls were busy stroking his cock and softly rubbing his heavy balls.

“We watched you and Blackie. It was so hot, seeing him lick your ass while you jerked off. We decided to come down and help if that’s OK.”

Mark grinned and agreed. “Come on over. Let me put sun screen on you both, so you don’t get burned.” Margaret said, “Why don’t you let us rub the sun screen on each other, then we can rub it on you?” Mark instantly agreed.

The girls began slowly rubbing sun screen on each other’s backs, focusing on their asses and legs. Once that was done, they faced each other and began rubbing from their faces, down lower. They spent a lot of time rubbing the oil on their breasts, down their stomachs and focusing on each other’s pussies. Mark was slowly stroking his cock, watching the show.

The girls had Mark lay down on his stomach and began rubbing the oil on his back, legs and butt. Margaret slowly spread his ass cheeks while Mariane pushed her finger in his asshole all the way to her knuckle, pressing against his prostate. Marked groaned loud and tried to push his cock into the lounge chair. They had him turn over, so they could spread the oil all over the front of his body. Mark was in heaven. He had never been this turned on. His cock was so hard, it was painful. Margaret began rubbing the oil on his face, then down to his chest and arms while Mariane began at his feet, rubbing up both legs. The girls met in the middle at his hard cock and making sure every inch was covered in oil.

Mariane said, “You know, this oil is edible.” Mark said, “That is great! Let’s try it out. I will lie on the bench. You decide who wants to sit on my face while the other one sucks on my cock and rubs her clit. The girl who cums first will sit on my cock.

Margaret and Mariane did paper, scissor, rock and Margaret won. She immediately placed her legs on either side of Mark’s head and sat down firmly on his face. Mariane, meanwhile, kneeled down between his legs and started licking his cock and balls.

The odor of fresh pussy got Blackie’s attention. He walked up behind Mariane and started licking from her asshole all the way up to her clit. Mariane tried to scream, but with her mouth full of Mark’s cock, it just came out as a gurgle. She could not believe how wonderful Blackie’s tongue felt. She was humming around Mark’s cock, which brought his close to cumming.

Margaret saw what was happening, so she bent forward and grabbed her sister’s tits and pinching her nipples. Mariane’s pussy was gushing her delicious juice all over Blackie’s mouth and face. Blackie then jumped up and wrapped his front paws around Mariane’s waist and drove his large red cock into her pussy. It went in all the way and Blackie started hammering away like a fast-battering ram.

This brought Mariane to cum immediately. Blackie’s knob jammed into Mariane’s pussy, locking them together. When he started cumming into her pussy, this caused Mariane to keep cumming. She wasn’t sure when one orgasm ended and the next one began. It seemed like one, long continuous cum. She and Blackie were tied by his knot for about 20 minutes.

Margaret had also cum multiple times from Mark’s tongue and fingers rubbing her G-spot. She turned around and laid down on top of Mark, kissing him and tasting her delicious pussy juices on his face.

Since Mariane was still tied to Blackie, Margaret sat up, aligned her pussy with Marks cock and slid down in one smooth slide until seated fully.

Al three were moaning in sexual ecstasy.

Mark seriously wanted to cum inside Margaret, but did not anyone to get pregnant. “Are you two on birth control? I am right on the edge of cumming.” Both girls stated they were on the pill. Margaret told Mark she wanted him to fill her pussy with his cum, which he did.

The powerful pulses of Mark’s hot thick cum blasted into Margaret, causing her orgasm to explode again and again.

Blackie’s knot had shrunk enough to free his cock from Mariane’s pussy. He immediately turned around and started licking her pussy, taint and asshole, cleaning up all his cum. This caused Mariane to cum again several time, as Blackie was very thoroughly cleaning her.

Both girls were exhausted and pressed into Mark’s arms on each side. All three dozed and relaxed.

None of them knew they were being watched.

Alice and Susan were given the day off by their husbands so they could continue unpacking. They were upstairs in Susan’s bedroom watching all the action below. Both women were very excited to see their children having so much fun. Alice said, “My God, your son’s cock is huge.” “I know, ” Susan said. “He is like his father.” “My pussy is dripping right now.” Alice said. “Mine, too, ” replied Susan. Susan turned to Alice and asked, “Have you ever had sex with another woman?” Alice grinned. “All during college, my roomie and I ate each other’s pussies until they were bright red.” “Well, ” said Susan, “What are waiting on?” The women stepped into a hot and steamy kiss with slashing tongues. They started undressing each other, their mouths tasting each newly exposed flesh. They fell onto Susan’s bed in a 69 position, practically devouring each other’s cunt. Periodically, they would roll over, so each could be on top. Both loved to lick each other’s asshole, as well as their pussies. Both would also stick one or two fingers in both holes.

After both had cum over and over again, they just relaxed side by side on the bed. Alice asked, “Have you ever fucked Mark?” “No, but I have thought about it a lot, especially since he has grown so tall and large.” “I know. I have never seen a cock so large, ” said Alice.

“You know, ” Alice said. “We could get the girls to go home and take advantage of the current situation.” “How, ” asked Susan excitedly.”

“Well, the girls are supposed to be unpacking. So, I could call them and say I was coming home to help them unpack.” “Wonderful idea, ” said Susan. So that is what they did.

When the girls cell phones rang and they talked to their mother, they went straight home so they would look busy when she arrived.

Meanwhile, Susan and Alice shaved each other’s pussy nice and smooth. Of course, they each had a little taste, as well.

When they walked out the patio door, Mark was lying down with his eyes closed, so he did not hear them approach. When their shadow fell over him, he opened his eyes to the two beautiful and naked women standing over him. “Mom, you’re naked!” Susan smirked and said, “Look who’s talking.” “Mrs. Wilson, you’re naked as well. What’s going on?” “Oh, sweetheart, call me Alice. I plan to get to know you extremely well. Actually, both of us are.”

As Mark was staring at his mother, his cock started rising and getting harder. “Hi, baby. Do you like what you see?” asked Susan. “Mom, you are so gorgeous, I have wanted to fuck you since I was twelve.” “Well, baby, now is your chance.”

Alice said, “We were watching the activities you and the girls were having and decided to join in on the fun. Your mom gets to fuck you first, while I ride your tongue. Is that, OK?”

“Oh my God, yes. Both of you climb on, ” exclaimed Mark. So, they did.

Susan slowly lifter her left leg as she straddled Mark’s groin. She wrapped her hand around his hard cock, aimed it at the entrance of her pussy, and slowly lowered herself onto his hot cock. She was so wet, his huge meat slid in with no problem until she was seated fully. “Oh my, baby, you fill me so good, ” exclaimed Susan. He was stretching her pussy so much, it was slightly painful. She ignored the little bit of pain because of the wonderful pleasure his throbbing cock was giving her.

Alice, meanwhile, was lowering her pussy over Mark’s face. She could feel his tongue lying flat and sliding up from her taint to her clit. It was incredible. Her juices were flooding his face and mouth. Then she felt his two fingers swirl lightly around her clit. Her heels dug into the frame of the lawn chair and her back bowed and she came with her whole body. Her thighs clamping around his ears, her spine lifting, Mark’s name breaking in half in her mouth, a long shaking wave that he rode out with her, gentling his mouth as she crested and came.

Susan was leaning over Mark, rubbing her nipples over his hairy chest. Suddenly, she felt a huge tongue licking her asshole. She started to raise up, but Mark wrapped his arms around her. “It’s OK, mom. Blackie like to join in the fun.” As the big dog's tongue lapped through her warmly seeping pussy slit, her glistening pussy lips clung to it like a woman clutching at her lover.

The rough texture of his tongue served to bind her tender pussy folds to it. And then Blackie did something that was so exciting, it fairly took her breath away. All of a sudden, he drove his cold wet snout right up into her steaming pussy flesh, wedging it in as deeply as he could. Then when he'd done that he began punching his nose in and out of her convulsing pussy with a savagely swift, machine gun-like movement. This was totally the most mind-splitting experience she'd ever had. His nose was pumping in and out of her pussy like an oil drill, making her lust spiral higher and higher with each lewd bestial thrust. She could feel the bristly tough hairs all around his handsome jaws whisking in and out of her cunt as if they would rip her to pieces. But the pain didn't matter; nothing did. There was only this wonderful feeling in her pussy which had turned her body to jelly. She came so hard, she almost passed out. “Mark, baby, where did he learn this?” Susan gasped out to her son. Mark replied, “I don’t know, mom. All I know is all the girls who have been with us, love it. They have returned for a repeat several times.”

Mark had not cum yet and Alice wanted to experience the Mark and Blackie fuck-team for herself. She gently rose up from his face, her pussy juices flowing freely onto his face. Mark smiled up at her, licking all it all up. Both women laid down alongside Mark, one on each side. They both encircled his huge cock with their fingers.

“My turn to be team-fucked, ” exclaimed Alice. “Go for it, Alice. You don’t want to miss this.” Said Susan.

Susan slowly rose up, still slightly dizzy from her hard cum. She slid one leg over Mark’s lower abdomen and slid down until her pussy lips touched the tip of Mark’s cock. Mark place his hands on her hips and guided her on his cock. Susan let out a large breath when he pushed her down, empaling her completely. She was so wet, there was no resistance. “Oh, my, this is the biggest cock I have ever had. It is stretching me so good.”

Alice grinned down at her friend. “Wait until Blackie does his part. You will not believe how delicious that will feel.”

Mark said, “I believe Blackie will want a little more, this time around. Have you ever been double fucked?”

“No, I haven’t, ” Susan replied, “but I am eager to try it.”

Mark smiled. “All the other girls who have been here loved it.” He called out, “Blackie, mount.” Blackie, who was behind Susan, raised up on his back legs and wrapped his front legs around Susan’s waist. His huge red cock slid into Susan’s asshole all the way. Susan screamed out in both pain and pleasure. Again, his cock worked like a machine gun, while Susan wailed. Mark didn’t even have to move, Blackie’s cock pushed and pulled Susan’s pussy up and down his 10-inch cock.

Alice decided it was time for her son to eat her pussy. She climbed up and lowered her body down on Mark’s face, where he eagerly awaited her. “God, mom, your pussy tastes delicious. I have waited years to eat you out, ” mumbled Mark, his mouth full of his mother’s pussy for the first time.

Alice leaned over and put her hands on each side of Susan’s face, trying to kiss her. It was difficult, because of Blackie was fucking Susan so hard. Susan grabbed Alice’s shoulders and managed to return the kiss with both tongues pushing each other. It was almost like their tongues were fucking each other.

Susan was in heaven. Her pussy and asshole were being pummeled and her mouth was being orally fucked by Alice’s tongue. All four, three people and one dog, reached orgasm at the same time, or it certainly felt that way. Susan finally collapsed on Marks chest. She was still tied to Blackie, but she did not care. After about 20 minutes, Blackie was able to pull out. All three humans were exhausted. They had no idea that Margaret and Mariane had witnessed the entire orgy from their bedroom window. Both girls decided they were going to repeat the orgy tomorrow.
