A visit with sister in law and nephew

A few weeks ago, I wrote about the time I fucked my drunk sister in law, wife’s sister, when she was visiting our house. If you recall the story, as I was fucking her, she kept calling me by her son’s name as my dick was sliding in and out of her wet cunt. Not being sure if she and my nephew were really having and incestuous relationship or if it was her fantasy didn’t matter, because the thought of it got me really hard. Last week, I had to go to their city for business and her husband was going to be gone dove hunting and invited me to stay at their home so he would know she was safe while he was gone. I told him I would be happy to, hoping to get a little alone time with her and hoping the wine would once again work its magic. Arriving at their home late in the evening after her husband left for the dove hunt, I was bummed to see that nephew’s car was in the driveway. He is a student at the local junior college not far from their home and lives in the frat house. The house was dark, so I opted to use the key they keep hidden under a plant on the front porch to let myself in. opening the front door, I could hear sounds coming from the in home theater, so I walked towards the sounds to let sister in law know I was there. As I approached the door, the screen was playing a hot and sexy porn movie with the star being spit roasted by two well hung studs, each slamming their huge cocks in and out of the actress. Sister in law was kneeling between nephew’s legs as he sat on the couch. His head was leaning back with eyes closed and I could see the top of her head bobbing up and down, taking his cock in her mouth. Moving a little closer, I could see both were completely nude, her eyes closed as she savored his spit covered member. Standing there, watching for about a minute, the erection growing in my pants at how expertly she took him deep into her mouth. The ironic thing is that her husband has confided in me several times that she doesn’t enjoy sex and he only gets pussy on his birthday, anniversary and may one or two other times a year. Little did he know that she was getting cock from their son and she seemed to be insatiable?
Clearing my throat, both about jumped out of their skin and were grabbing for their clothes that were strewn about the room. Stammering, asking what the hell am I doing there, how long I had been there and what had I seen? Poor nephew’s cock was shrinking as he covered it with his shirt. I told them her husband asked me to stay while I was in town and apparently he neglected to tell her. They didn’t have to stop just because I was there, that I was loving the show, it was even better than seeing the girl getting double penetrated on the screen I said. They were still very reluctant to restart until I told them that I would really like to join in, otherwise, I would have to rat them out to husband. Both nodded their heads yes and I started to get undressed, the tent in my pants showing my obvious excitement. While removing my shirt, sister in law said that when she visited our home alone that she dreamed we were fucking, then she ask if it was a dream, smiling, I told her it was a dream come true for me and yes, I had fucked her while she was passed out drunk. Not only that, but while I was fucking her, she kept saying her son’s name and I had wondered why. They started talking and confessed they had been having sex for a few years, the first time being while husband had taken clients away for a golf weekend and the two started drinking and doing shots. By now, I am nude and my erection is pointing straight at her, nephew has also started regaining his wood and we all sit together on the couch, sister in law in the middle stroking a cock in each hand. The girl on screen is taking a massive load of jizz in her face from one dude as the other is busting his nut across her butt cheeks. Spreading her legs, she pulls her son’s head towards her clit, begging him to eat her out as she leans towards me and starts sucking. Her mouth is like a vacuum as she bobs up and down on me, moaning from the pleasure being received from the attention on her clit. As she starts to cum, it drives me over the top and I also explode into her mouth where she hungrily swallows my gift. Coming up from her pussy, nephew’s face is glistening with her juices before moving up her and impaling her. Pulling her ankles up to his shoulders, he leans forward almost folding her in half as he fucks her long, hard and fast. She I telling him to fuck her, make her his whore, use mommy for the slut she is and it doesn’t take too long before he blows his wad into her wet womanhood. Holding this position for a while after they finish until he slips out and she unfolds. Mom, he says, let’s take this party to your king size bed, which we did for the rest of the night and the following night also….
