My girl and our gf [MFF]

My girl and I ( long term) started having amazing 3somes with our neighbor a couple years back (very cute, huge titties, professional woman). We were hooking up with her thru her breakup with her long term boyfriend. we spent alot of time taking her on dates with us, nursing her broken heart back to health.

fast forward a year or two, Me and my girl took a vacay to her new house down in San Diego. Amazing night, and at one point a friend of hers showed up from the military. it was a surprise to us, but im pretty sure she had it planned.

we are all taking shots and smoking hookah when she asks me if she can shotgun me a hit. i say yes and she starts making out with me in front of my gf and the guy.. this is a little different cause i dont think we had even kissed til then, just sex. so my gf and the guy are watching and naturally he asks if he can shotgun her a hit. she says yes and does it, with him making out w her at the end. i had never seen my girl w a guy and it freaked me out. we all had a quick convo and our friend asked if i wanted the guy to leave. i said yea and she actually quickly kicked him out.
