The first time I brought my girlfriend home, I nervously entered her house and found...her incredibly sexy older sister 'Sora-san'! Her ass sticking out from her shorts, her bust, and dirty talk whispered in my ear...I was a virgin and couldn't handle the stimulation, getting an erection. Noticing this, Sora-san secretly fondled my crotch while standing next to my girlfriend...and I lost my virginity before she did.
