PRED-886 - Every night, my girlfriend's sister, whose sex noises I hear, seduces me while she's away, and I end up cumming inside her multiple times - Nanao Saitsuki

[I-cup Breasts][NTR] I'm dating my co-worker, but every time I stay at her place, I hear her sister Nanao having loud sex. One day, my girlfriend is called into work, leaving me alone with her sister. Nanao finds me struggling and teases me with her breasts exposed, asking if I'm still pent up. I can't resist. From a bath-time blowjob to intense cowgirl sex, she seduces me all night. She even grinds on me while I'm on the phone with my girlfriend! Even though she's coming back soon, we don't stop until I've ejaculated inside her three times.
