I dont think Ive ever actually caught anybody myself. Ive known its going down in the next room and stuff, but thats diff. One time however, there was a party and it kinda died down it was some girls and my freinds left. I walked into the bedroom and 3 of my freinds are with 2 girls fondling / making out. All heterosexual stuff obviously, but there obviously was some sharing involved. Either way it was a strange scene.
