Okay so it’s currently 4 am where I’m at, but when my sister got home she told me she had a really shitty day and just wanted to watch movies on the couch and she asked if I wanted to join her, obviously I said yes. She decided to start watching the twilight saga from the beginning. She came out in an oversized t shirt and a blanket to lay on the couch. After finishing the first movie I started to yawn a bit and about halfway through second I did it again so she asked if I wanted to go to bed. I told her no it’s fine I enjoy spending time with her. She eventually asked me why I was so far away and asked if I could lay under the blanket with her because I have really high body heat and she was cold. She started to rub her feet on my legs to warm them up and snuggled up a bit closer. Next think you know I’m asleep but when I woke up she was still laying with me asleep on the couch but her head was on my lap sideways, it was very comforting so I decided not to move and noticed her ass was uncovered by the blanket, SHE WASN’T WEARING ANYTHING UNDER!!!!! I got my phone and tried to take a few pics of her pussy but it was too dark and I didn’t wanna risk the flash waking her up. I started getting hard at the thought of her being half nude next to me and her face was on my cock, I tried to adjust so she wouldn’t feel it and it ended up making her move. She positioned her legs perfectly where her pussy was slightly showing if I put my phone by it, while staring at her pussy through my phone my cock started throbbing and woke her up. I pretended to be asleep and acted like I was waking up at the same time as her. When she got up she said “you must have been having a great dream if you’re waking up like that” I felt so embarrassed but she told me not to worry because it’s something I should be proud to have with its size. She asked if I was gonna stay on the couch and said she was gonna go to bed in her room. I don’t know if she wanted me to follow but I was so nervous and didn’t know what to do so I stayed on the couch. Did I fuck up my chance or do I still have a shot?
