I was fucking my wife Tina on a Monday night. My 7 inch cock was buried deep in her tight pussy. She was riding me with her tits in my mouth. My nuts were slapping her soft ass as I pounded her from below. I felt her pussy tighten around my member and I couldn't hold it any longer. I was fucking her for the last 20 minutes.
"That's it Bob. Make me cum. Shoot your load inside my tight pussy..." Tina screamed as I erupted. I could feel my ejaculation as it powered through my cock deep from my balls. My balls emptied itself into my wife. I was still pounding her as I came and I felt hot goo seep out onto my shaft and testicles. Her pussy was convulsing and I could feel her hot pussy juice flow onto my lap. We were moaning in unison as we climaxed together.
It was a week before our wedding anniversary. It had been 20 years since we were married. We got married when we turned 21. We have known each other since high school and college and we lost our virginities together. That is to say, we have only had sex with each other. My son Max was born two years later, a week after our anniversary. This year he turns 18. At the age of 41, I would say we looked great. I work as high school gym teacher hence I have toned muscles and broad shoulders. I am going slightly bald and my once six packs is currently one flat piece of tummy. My wife Tina is a totally hot MILF. She was a dancer in high school and college and currently works as a ballet teacher in prestigious dance school. After having our only child, she still continued dancing and managed to maintain her figure. She is 5 ft 6 with shoulder length dark brown hair and round brown eyes. Her face has aged a little but not too much. She has 34C breasts and her tummy is flat from a lot of dancing. Her dancing also has made her legs slender and long and toned. She sort of looks like the porn star Selena Silver. My wife doesn't shave her pussy. She loves it natural and I sort of like it too.
"So honey, next week is our 20th year together as married couple. We should celebrate" I said as she rolled off me. My dick slumped onto my tummy, soft but still long. Some cum was still coated on the head of it.
"Yes dear" she agreed. "We need to spice up our sex life. After all it's been 20 years."
I couldn't help but agree. I consider myself as an open and willing husband. I let my wife do a lot of things. Over the years we have tried many different things. On our 10th anniversary we started having sex in public such as beaches and one time in the elevator. On our fifth anniversary, we tried anal sex and from that day onwards we enjoyed it. I try to fulfill my wife's sexual desires and this year was no different.
"What's on your mind?" I asked. She gave a sly smile and sort of blushed. "What?" I asked again.
"Do you sort of notice how Max has grown?" she said quietly. I nodded. Indeed my only son has. From being a pudgy childish kid, max now looked more of stud. He had short light brown hair and broad shoulders like me. He was nearly 6 ft tall with toned arms and legs. He ran everyday and spent the weekends in the gym. The only problem was that he was sort of shy. As a result he hadn't had a girlfriend before. He was good kid and I knew that he would make a lucky girl happy one day.
"Yes" I said.
"Well I sort noticed how good looking he has become and I feel sort of attracted to him. I often fantasize about him and me doing it together."
I wasn't shocked at this idea. I had thought of this too. I have read many incest stories online and have had a sort of fantasy. I also have acquired a fetish of threesomes especially when two guys are doing one girl. It would be nice to watch my wife being fucked. It would be nice to have her suck me off as she gets banged by another guy. I grew hard thinking of this and I grew harder when I realized that my son would be the perfect person. He loves his mother and would never hurt her.
"Honey, I think that it would be fantastic if you slept with him. But only in one condition." She looked at me. "I want to join in and I want it to be filmed." She grinned at the idea and we kissed. She grabbed my re-erected cock and began stroking me and spreading our sex juices over the whole organ. We fucked again last night and I blew a huge load inside her.
A week later Tina and I went out for dinner on our anniversary night. We came back at around 10pm to find my son jerking off in his room to porn. We could see him from the slight opening of the door. We knew he was doing it for awhile but we didn't let him know. Apparently he had just begun as he was sitting on a chair with his gym shorts at his knees and his gym t shirt on his bed. He had returned from his work out session. Usually we gave him privacy. I went to my room to get the camera set up. I stripped and sat in my boxers. Tina went to Max's room and knocked on the door. She changed into her bathrobe. I could hear Max being startled at my wife's sudden call. He thought he was almost caught but he didn't know what awaited him. Tina called for him to meet her in our room in five minutes time. By then I had my camera set up.
Max knocked on our door. We were sitting on the edge of the bed, the camera on the tripod at the foot of the bed. Max entered and was wearing only gym shorts; his dick was slightly visible from his recent erection that fully hadn't gone down. He looked a little nervous. Tina got up and took off her robe to reveal her sexy body. She was in a black lacey bra and a matching black thong. She let the silk robe slide off her beautiful soft and smooth skin.
"Oh my god mom, what the hell are you doing?" Max cried. He was surprised at his mother's actions. I just chuckled at this. Tina crossed the room in three steps before her son could escape. She quickly placed her hand on his crotch. He looked scared.
"Max, your father and I have realized how much you have become of a man. You are so handsome and I bet a lot of girls want to be with you. It is a shame that you haven't had a girlfriend yet."
Max looked confused now. He didn't know what was going on but he sort of enjoyed his cock being rubbed his mother. There was visible tent now in his shorts.
"I have fantasized of you having sex with you and I want myself to be your first" my wife said seductively. With that she kissed my son on the lips tenderly. Max sort of melted and closed his eyes as his mouth was probed by his mother's tongue. She was rubbing his cock with one hand while the other took his hand and placed it on her firm breast. I could tell my son was enjoying it. He gave Tina's tit a squeeze and my wife grinned and giggled.
She started to kiss his bare chest starting from his neck down to his flat tummy. He moaned at the feeling. Then she got on he knees and slowly pulled off Max's gym shorts. I was hard now and my dick poked out my boxers through the make shift zipper in the front. My head was visible now. Tina pulled off Max's shorts and received a slap on the face from his hard cock. The three of us laughed. I took of my boxers and stood there. I was proud of my cock. It was uncut and seven inches long. It wasn't very thick and was average in girth. My balls and crotch were covered in thick hair which I trimmed weekly. I pulled my foreskin back to reveal a shiny red head with a drop of precum forming at the piss slit.
