One time a few years back.. my wife showed up at the house after she had went out clubbing with some friends. She called ahead to let me know she was coming home with company, so I went and made sure the bed was cleaned off etc.
Anyway they show up, introductions are made and we head up stairs.. they go to fucking in various positions. It looks like he chose doggie to finish off. He is pounding away... He starts that pre nut grunting and groaning .. the wifey starts yelling... "Yeah!! Get your nut!" "Get your motherfuckin nut!"
