We are a totally horned up couple dying to make the jump into MMF threesome sex. I particularly want to see my girlfriend passionately kissing another man then watching her rub his dick till it's red hot before releasing it and taking it in her mouth . This will be our first time so I'm a bit worried about what will happen when I inevitably come seconds into the encounter, should I just let loose then watch the show or am I better holding on and attempting to fuck the sloppy seconds? How should I approach this? We are both seriously gagging for this to happen and fantasise about it all the time.
