Here is a nice best friend story...
A couple years ago, my chicks bff moves back east from Cali after breaking up with her boyfriend, and needs a place to stay for a few weeks, till she can get her shit squared away and find a place.
Anyway, one morning, I am running a little late, snooze bar got the best of me. So, I am taking the dog out for his morning walk and there she is, naked in the downstairs bathroom in front of the mirror putting on makeup, I froze on the landing. Her bare ass was nice and smooth and round. In the mirror, I caught a quick glimpse of her massive breasts, 38D, and their big pink areola. Her nice soft round tummy. Then the dog came bolting down the steps from behind me rushed toward the bathroom which freaked her out as she was trying to slam the door behind her, to keep the dog out. The whole thing happened in a matter of seconds and I am 99% sure she didn't see me in the mirror. I waited a couple of seconds, before noisily coming down the second half of the steps and took the dog out.
It was long hard day for me. I could get the thought of my girl and her friend naked, in bed with me having a wild ass threesome. Damn. Hadn't thought about that in a long time.
