My moms bf and I had a fling

My moms bf dropped of my mom who passed out because she had one too many margaritas and when they arrived I was in the living room as I wasn't expecting then to come back so soon, I was in my pjs and he was carrying my mom I had no chance to change my pjs is just an oversized t shirt and just underwear I was sitting with my legs cris crossed and I caught him looking and then we made eye contact we kinda ignored it and I helped him putting my mom to bed then once she was sleeping I went to the living room and he followed and I continued my movie (obsession) and he started asking questions about the movie once I caught him up to he sat next to me I was covered with a blanket he then went under the blanket also and he then proceeded to ask about me going to the gym and he said I can see the results coming in you have thick legs and I said yeah I noticed to staring when you first came in and he said it wasn't his intention but he is a man at the end of the day and is very horny at all times that's when I told him I've heard him and my mom when they're having sex and I it sounds like she's having a really good time and he started rubbing my leg and then proceeded to go higher and higher till he got to my pussy and he started fingering me I was super wet and I took out his cock and gave home head while he kept fingering me.
