Last night me (24M) and my GF (22) had a movie night with our friend (25F) We ordered some food, then I set in the same sofa with my GF and covered with a nice blanket, and our friend was in another chair. It was dark, only the TV light, and my hand on my GF’s thigh, after 20 minutes or something I started to get hard, so I grabbed her hand and put it on my bulge, she moved her hand softly and I got so hard. Meanwhile, our friend got a call from the delivery guy, she stopped the movie and turned on the lights, then she asked me to get it from the door, I couldn’t hide my boner so i get up and run quickly to the door, but she was looking at me and definitely saw my boner. When I got back, she told us to not use the blanket while we eating because she didn’t want it to get dirty. My GF couldn’t hold her self, so she went back to do what she was doing without the blanket, I tried to stop her but couldn’t, our friend saw us and laughed, she said you won’t stop? My GF shook her head (no), then she threw the blanket on us and said (don’t cum on it please) She was watching us having fun and it was embarrassing for me, but I think we all like it.
