Which are the best positions for a threesome?
Basically, my girlfriend and I have been doing things for quite some time now to eachother including playing with eachother and making out. I have a guy friend who seemed quite interested in me and I asked him what one of his fantasies was. He said it was to have a threesome with two girls so my girlfriend and I said we'd do it. However, we're a bit lost on how to actually handle it. We know what to do if it's guy/girl or girl/girl but are lost on girl/guy/girl positions that would work. Any help is wonderful.
