Bro, You Don't Get to Boss Me Around

Ah Hao is a programmer whose family has taken in a newly adult stepsister. One day he passes by her room, the door not fully closed, and sees her lying on the bed touching herself. He doesn't make a sound—instead he quietly records the whole thing on his phone. After that, every day when he comes home from work, his stepsister mocks him sarcastically: "Got fired again, bro? You're this useless and you still have the nerve to come home?" Ah Hao puts up with it for a long time. Until one night, he calls her into his room and plays the video right in front of her. Her face goes instantly pale; she tries to grab the phone but he pins her to the bed. "Try talking tough now." He uses the video to threaten her, forcing her to undress herself. She cries and begs him to delete it, but is still forced to spread her legs. Ah Hao enters her directly, and while he's doing it he holds the phone up in front of her eyes, making her watch the footage of herself masturbating. "Weren't you so good at mocking me? What now?" Her voice breaks apart with every thrust, and she can only bite her lip and endure it. When it's over, Ah Hao saves another copy of the video, pats her face, and says: "From now on, you'd better be a good girl every day... otherwise this video won't be seen by just me."
