I live with my boyfriend and my female roommate and most nights, we watch porn together on the couch, using the TV. It's whatever porn looks good, nothing specific and after while someone starts masturbating, closely followed by the rest of us. Sometimes it ends with my and my roommate having sex, or my bf and I, or my bf and roommate. Last night we had a 3dome though.

So we were all on the same couch, watching stepsis porn, bf in the middle, cock out and slowly stroking and I'm on the left dressed but plugged while my roommate was bottomless on his right, rubbing her clit. She gets up, makes a joke about how I'm clothed and we laugh as she pulled my pants off... she notices I'm plugged and moans, getting down to eat my pussy. I lean back and enjoy it and after a few minutes, my bf gets up and starts fingering her from behind before finally sticking his cock inside her. She moans really loud and keeps licking my clit. After a few minutes he pulls out to try and last longer, giving himself a break. So I got in the floor with her and we started tribbing, rubbing clit on clit while kissing and moaning. Apparently that was to much for my bf because he came up and just immediately came right on our faces and tits!

Obviously we laughed and continued ourselves, smearing his sperm all over us. He watched for a few before getting cleaned up. We both came and were getting dressed by time he got out of the shower
