My girlfriend's younger sister, who I met for the first time, was a female brat who looked down on me and made fun of me even though we were meeting for the first time. My younger sister, who has a cute face but is cheeky, doesn't see me as a man or even a human being, so she doesn't seem to mind the fact that I'm wearing no bra and her nipples are showing. I hate how cute even her nipples are! I couldn't help but reach for the defenseless female brat's nipples... At first, her younger sister refused the sudden nipple torture, but she couldn't stand it anymore as he continued to twist her nipples so much that she climaxed. Still, she took on a strong attitude, so I made her moan with further nipple torture, inserted my dick, and creampied her! I let my female brat sister, who grew up with a nipple and premature ejaculation condition, understand by having creampie sex until she is rehabilitated.
