Beth's flatmate comes in covered in mud but she has just put all his other clothes in the wash. As he strips out of the wet clothes he has nothing else to put on and has to stand there naked waiting for the washing machine. Beth keeps glancing at his cock and smiling and he soon grows an embarrassing erection. She tells him she loves looking at his dick and asks him to wank it. As he jerks off she opens her legs and reveals white lace panties. Along with her filthy talk thus soon has him cumming everywhere!
