BBC Dildo Role Play. You're over at your girlfriends but only her younger 18 year old step-sister is there doing homework. She tells you she likes a boy a school, but she's nervous, and is afraid because she has no experience like all the other girls do at her school. She wants to know if you'll show her your cock, and let her try playing with it for practice. Sucking turns to fucking, and soon your BBC is deep in her tight school girl pussy as she rides you balls deep. Her tits start squirting milk because she is so aroused by your cock! Don't worry she won't tell her step-sister.
