When I met my girlfriend's sister for the first time, she was a bratty girl who looked down on me and made fun of me even though we had just met. She has a cute face, but she's cheeky, and she doesn't seem to mind that her nipples are showing through her bra because she doesn't see me as a man or a human being. I hate that even her nipples are cute! I couldn't help but reach out to her defenseless bratty nipples... At first, her sister refused the sudden nipple play, but she couldn't stand it when he kept twisting her nipples and she climaxed. Still, she took a strong attitude, so I made her moan with more nipple play, inserted my dick, and creampied her! I made her understand with creampie sex until she was rehabilitated after I had made her nipples orgasm and prematurely ejaculated.
