My husband and I like, now and then, for me to be a total slut with a stranger, especially when I'm in the mood to fuck two guys at once, but I've never done it without my husband, nor have I done anything with the other guy that I haven't or wouldn't do with my husband. If this qualifies as slutty behavior, I like being on all fours with one guy fucking me from behind, alternating between my pussy and my ass, while the other one fucks me in the mouth, and I love being dp'd, one cock in my pussy and other in my ass, so I can feel them sliding against each other through the thin membrane separating them.
