SSIS-309 — While My Girlfriend Was Away On A Trip, I Had Sex With Her H-Cup Sister From Morning Till Night For 72 Hours.

Every man is attracted to an adult woman at least once... I was in a slump with my girlfriend, so I fell in love with her big-breasted sister. One day, she went on an affair trip with a senior from college... I couldn't hold back my feelings and confessed to her sister, who cheered me up when I was feeling down. "I'll be your girlfriend for just three days." For a limited time, I had sex with the naughty big-breasted sister who embraced me tenderly from morning to night, and I had forbidden sex as I pleased.
