As a shut-in NEET who had been cooped up at home, I was living each day on autopilot and constantly looked down upon by those around me. Especially my younger brother and his girlfriend, Yuna, always criticized me for being in the way. One day, after being mocked by Yuna once again, the pent-up stress finally reached its limit and I completely lost control. I violently overpowered her, and though shocked by my strength, she began apologizing submissively, succumbing to my sense of dominance. Satisfied with her reaction, driven by my desire for conquest and lust, I chose to forcefully dominate her. As a result, Yuna was drawn to my cock and gradually began to feel arousal. Seeing her like this only heightened my excitement, pushing our twisted relationship further into depravity.
