I was actually fucking my sister in law. While she was fucking hard on my rod i started playing with her brown hole. She jumped a bit and said..."what...the fuck are you doing?" "Shut up, its only a finger..."i said slaping her ass."I never did anal and dont want it" she said with a serious face. "Dont worry ...your ass is safe with me" but i kept playing with it so soon enough one finger was sliding in like her ass was lubed with a full tube. I made a sign to the guy and her understood. I had to be careful when I got up not to show my hard on. I told her okay i need to get to bed as well I waited for her to get up and go to the bathroom before she walked me to the door as she did that I grabbed her room key and put it in my pocket. Then she came out the bathroom walked me out and I went to my room.I was in my room for a few hours thinking to myself if I should even do what I was thinking I need to save my load and I could get into a lot of trouble. So went to her room listened. I’ve not been nude in front of a man other than Patrick since the Sunday afternoon I had been required to strip in a dorm room for Paul and Hank, part of paying off the bet I lost to them on the homecoming football game when I was a grad student. But now, this experience had almost that same underlying feeling. There was a distance between Patrick and me for the present. I was not nude because we were sharing loving feelings or a laugh or both. I was nude because I had lost a bet to him and was. All I could think about was that picture of Brian's cock so a couple days later while he was in the shower I grabbed his phone and text that picture to mine so I could always look at it and jerk off to it and its the picture I attached to the story. At that moment I started to look at Brian like most guys I thought were hot and that was how much I would love to service him. I told myself it was probably never gonna happen until one night about three weeks later it did. Brian and I decided not.
