I heard my aunt moan and push her ass back when my hard dick tried to make room between her ass cheeks. We stayed in this position for a couple of min...tes until the pics was taken, then the exciting contact suddenly disappeared and I was left with an huge hard on.After the party was over, I got in the car with my aunt an uncle, my uncle was quite drunk and my aunt was not in better condition, so I was asked to drive the short ride to reach their apartment.Once there, my uncle did disappear in. And once again my dick got even harder as I said "No, not really". She had me follow her while Mike waited smiling, and told me to get on my knees in front of her as she dropped her pants and sat on the toilet seat with her knees spread. She had me put my hands on her legs and shortly a stream of piss began to flow from her pussy. It really turned me on, and I offered no resistance when she took my hand and placed it into the stream of piss. Then she lifted it to her mouth and licked the piss. They seemed incredibly happy all of a sudden and they couldn?t keep their hands off of each other. At night I could often hear them through the walls as Bob was fucking Jen and Jen was moaning with pleasure and the bed was rocking back and forth. They made a lot of noise and didn?t seem to care if I heard it or not. In some ways I was jealous, but in other ways, I was content to just be the sister-in-law again. When I was five months into the pregnancy, Jen had a two day trip out of town on. "Yea Mum, you're doing a great job."She looked over towards me and saw me playing with my cock."I see that you are enjoying it whilst poor Mum has to slave away whilst being perved at and getting her all turned on and not allowed to touch my sooo wet cunt."She was bent forward with her arse facing up whilst wiping the coffee table. Fuck it looked inviting for me to get behind her and slip my shaft into her. Either hole would be nice, but no, I mustn't. Looking at her fanny, I saw a small trace.
