I'm not "that" kind of girl but I rode my best friend's husband's cock while she watched and masturbated. It was the hottest thing I have EVER done, staring at her while riding him, knowing that she loves his cock as much as I do, seeing her toy herself like crazy while he desperately filled my pussy. He came inside of me, and then we both took turns kissing him.
We're both "good girls" that got a little drunk and crazy. Best Friday night ever.
