My younger sister started looking down on me when she found out I was a virgin. It's genuinely frustrating! One day, I mustered the courage to push her down and forcefully initiated sex. Then, as if to get back at her for all the times she made fun of me, I thrust my dick in hard and vigorously moved my hips. She kept screaming 'Stop stop stop stop! If you thrust that hard, it'll feel weird! Do it more gently!' But I didn't stop. As a result, it seems like I made my younger sister cum multiple times!!! Of course, I also came inside her multiple times!
