While there are a lot of fantasies I have acted out, (me with another couple, foursome, double penetration, golden showers), I have never been in a situation of myself with two women. Any occasion of multiple partners has been 2 guys 1 girl, or 2 guys 2 girls. I would love to watch my wife secrectly from a closet while she licks another womans pussy or shares a double dildo with her. Another fantasy I've tried with a few willing women was to fist them, but although I've come close, I always get stuck at the big knuckles. I also wouldn't mind a women trying that on me. (My wife has come close, but wasn't really trying to do that.) Still, it felt great.
