Okay I'm 21 and my gf is 21. Lately when we have sex, she sucks a dildo at the same time...it really turns me on to watch her suck it whIle I fuck her...but I'm scared to let her suck another man's dick because I'm kinda insecure and jealous at times...but the thought of watching her suck another dick gets me hard....any thoughts or suggestions or good/bad experience with sharing gf/wife? I'm only scared that afterwards she'll want the other guy more or if he will try to contact her..just don't want it to backfire. Help!
