That JAV

This is my first girlfriend. When I asked her to let me into her house for the first time with my heart pounding, there she was... her older sister 'Sora-san' who has a lot of sex appeal! Her ass sticking out of her shorts, her breasts bulging, and the obscene lewd words she whispered in my ear...I, a virgin, was so stimulated that I couldn't help but get an erection. Sora noticed this and secretly played with my crotch at her side... I lost my virginity before she did.
