Your girlfriend is such a boring prude. She won't even suck your cock before work. After giving you a half-assed handjob she heads off, not worrying about your lack of orgasm. Luckily her slutty step-sister is home and wants to hang out with you. Actually, she wants to do more than hang out. Your girlfriend's whore step-sister Princess Kira can't resist showing off her massive tits and begging to suck your cock.
