Sapphire is your best friends girlfriend and while your girlfriend and her boyfriend are over at the showers you start talking to sapphire about the bikini she was wearing the other day. She noticed that you couldn't stop staring at her tits and decides to tease you with her cleavage, she undoes one of her shirt buttons and lets her nipple slip out, when you ask if she is doing it on purpose she gives you a cheeky smile and tells you to get your throbbing dick out of your trousers!
