In the middle of the night, a strange sound echoes through the house. Quietly peeking into my sister Tsubasa's room—rumored for her great figure—I find her fast asleep with a vibrator still inserted deep in her pussy. I've never seen my sister as a woman before, but her explicit appearance instantly ignites an uncontrollable arousal. Instinctively, I reach to pull out the vibrator, but the sensation excites me even more, and I end up sliding my cock inside instead. My heart races at the thought of taking my sister's pussy for the first time, yet I can't stop myself from thrusting harder and deeper. Rational thought vanishes completely. Overcome by lust, I unleash a violent creampie deep inside her pussy.
