Had two in my lifetime, both nowhere near like in the movies. The first was while I was in AIT at Ft. Sam Houston. They were locals and were "girlfriends." I had been kickin it with them for weeks, spending all of my pay on these chicks. One weekend we got tipsy, took a cab back to their place. Started messing around on the couch. Long story short, one of the chicks was lightweight mad that her girl liked real d. When both was suckin me, one was going ham, the other was doing little kitten licks on the shaft. I was both mad and excited. When I was hitting the "live" one from the back, the other was trying to make her eat the cat. But, she really couldn't because I was putting my all into those strokes. I was in post-basic training shape so I was going ham.
Needless to say, that was the only time she let that go down.
I need that Napoleon Dynamite time machine.
If I knew what I know now.......I would have worked that situation much better.
Probably not. I would have still messed it up.
