My friend told me a stroy about him and his girlfriend?

he told me this story about how is him and his girlfriend do role reversal where she dress in a boy outfit and he dresses like a girl they set up a fake date sort of thing at home then they walk each other to the bed room and make out and all the fore play and stuff she takes off his clothes and he like wise and then she puts on a strap on and makes him suck on it for a few minutes then she ***** him with it I known that part is called pegging but I thought wow how kinky is this and I want to try it myself I want some input on this mainly from girls he seemed to enjoy it and also told me the dress up part is what makes it work
