Not that i know all about this shit.. but, hooked up with a girl, sex relationship thing i call her once a week and she calls me once a week.. okay sometimes more.. but its kind of a deal we have to keep things goin. Anyway, she tells me her and a friend fool around time to time, i later find out she has two girls that she hangs out with.. She tells me she wants to bring one over, one has refused compeletly saying not into that and the other one well... i experienced my first threesome, works out nice when the girls know eachother.
