Nice Nephew and Niece Part III

Note : This story is completely fictional!

After our secrect party with our mystery guests, Tracy was really horny all the time. Always asking questions about who our new sexual playtoys were. I told her if she knew she would be too shocked to continue. She promised me she was OK with whoever it was. So,,,,

We went out partying one night and she got really drunk, again, and was begging me to party with our mystery guests again. I made a phone call and set it up. We drove home and Tracy had her fingers burried deep up her cunt in anticipation. We came in the door and she heard those familiar sounds coming from her son's bedroom, but the kids were supposed to be away for the evening. I told her prepare to be shocked, we opened the door to Josh's room and low and behold there was Josh and Robin locked in a 69 going at each other. I thought Tracy was going to faint, but she stood there silent, I checked her cunt and it was flowing. The kids looked up, smiled, said hi mom and continued on eating each other out. I was about to explode. Tracy gasped, it was Josh and Robin the other night? I just smiled and led her to the bed.

I suggested we play a little game. As we undresssed I pulled out a box from under the bed, inside were 4 pieces of paper with our names on them. I said we would all draw a name, one at a time, and preform oral sex on the person's name we drew. I, as the oldest would go first, I drew Josh's name, Tracy was shocked because she didn't know I was bi much less that her son was also bi. Josh stood up and I knelt down and slowly made love to his cock with my mouth, I let his cum slip out the corners of my mouth when he came, then I french kissed Tracy and let her taste her boy's fresh hot semen. She purred like a kitten.

It was Tracy's turn to pick a name, she drew Robin. Robin said come lick my hot cunny mommy, Tracy stood frozen for a second, but I pushed her toward the bed, she knelt down and tenderly kissed and licked Robin's pussy, Robin grabbed her by the back of the head ground her cunt into her mother's mouth. Tracy had 2 fingers and her tounge up Robin when she squealed and came on her mother's face. Josh now drew his mother's name and told her to sit on his face as he lay on the floor. Tracy was beyond stopping now, she held her ass and cunt above her son's head and he dove into her with a vengence, alternating pushing his tounge up her pussy and her asshole, she went wild with delight and couldn't resist leaning over and swallowing his cock. They both came about the same time. Now it was Robin's turn and my name was the only one left, I was about to explode, I sat on Robin's chest and forced my dick between her lips, each deep breath she took I forced my dick in her throught farther and farther until I shot my load deep down her throught.

After we rested a short while, I had another idea. Josh and I would sit in chairs side by side and the girls would alternate lowering themselves down on our hard cocks (5 minutes on each cock until we came), we both fucked Tracy and Robin until I came in Robin's tight pussy and Josh came in his mother's steamy cunt.

From that night on we were a torid little family, fucking each other every day.
What could we do next? We will just have to wait and see.
