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 sister is home and wants to hang out with you. Actually, she wants to do more than hang out. Your girlfriend's whore sister Princess Kira can't resist showing off her massive tits and begging to suck your cock.
