The female friend (*best friend's girlfriend) I was drinking with missed the last train and ended up staying at my house! I lent her my white t-shirt to change into, but it was too big for her, and she was strangely sexy and horny... She was someone I should never touch, but I couldn't resist, so I touched her breasts from behind. She didn't like it at first, but then I forced her. As I continue to rub it... my female friend's pussy starts to get wet... she says fuck me but she's serious.
