My girlfriend (24 ) and I (25) went out with some friends to drink at someone’s house. It all started normally just drinking and having fun, we all got pretty drunk we ended up staying the night there. I don’t really remember falling asleep but I woke up in the couch and my girlfriend was missing and started hearing noises upstairs but no one else seemed to wake up so I went to check it out. I peeked Into the room and saw my girlfriend just riding on my friend like crazy, moaning in a way I never heard her before. I thought I was going to be angry but ended up just watching the whole thing. She was bouncing up and down on him, moving in various positions, sucking his Dick a lot. I enjoyed the whole thing I ended up “pleasing” myself. Once they were done I head downstairs and pretended to still be asleep she came and laid down with me and kiss me, I could smell the cum all over her body. Ever since she invites him over to our place just to have a little fun. BTW he is about 8in big I’m let’s just say barely hitting the halfway mark.
