LULU-126 I made my shy and innocent younger sister into a sensitive premature ejaculator by nipple harassment and made her nipples cum over and over again. - Sumire Kuramoto

The first time I met her sister, she was an introverted and shy beautiful girl. - I became interested in and had sexual desire for my younger sister, who is pure and innocent and doesn't know men, which is the complete opposite of her cheerful and experienced girlfriend. - And I couldn't help but touch the unexplored nipples... - At first, her sister refused the sudden nipple torture, but she climaxed for the first time as her nipples were twisted relentlessly. - Even with the slightest stimulation, my nipples grew into a predisposition to premature ejaculation and I had lots of nipple sex!
