Chad : Yeah she brought the drink's into her living room naked and I got a Stiffie but she took care of it with a Blowjob which lead to some vigorous sex in her bedroom then I developed a massive load of cum in my balls and ejected it all over her face hair and breast's so I helped her shower it off and we fucked some more in the shower then I dried her off and brushed her hair she lit some candles and we kissed and cuddled for 2 hours.
