Your stepsister has sneaked into your room, jumping on top of you in your bed and talking about how annoying you are, how much stronger she is than you, and how your going to submit to her will. She teases you, exposing her curvy body, her strong thighs and ass, telling you that you're no match for her! She will can and will own you! She starts to ride you and you try as hard as you can to fight it but she's too strong! She teases you, telling you to try and escape and watching as you realize how helpless you are. She can tell how turned on it makes you, her strength, and her own arousal only makes her clamp down tighter, harder. She is inescapable as she laughs, telling you that she's going to break you. Moaning, she rides you harder and faster, getting closer and closer to orgasm. You cry out, unable to stop her, as she leans in and begins to cover your face with her big, round, heavy tits. She teases you, asks if you can breath and laughs when your muffled replies suggests that you cannot. As she rides you to a shuddering orgasm, she purrs, "now you're going to lick me clean!" She scoots onto your chest but you refuse. "Well I'll just make you then!" she laughs, turning around and jiggling her formidable, strong ass at you. "I'm going to wrap my pussy lips around your mouth and make your every last drop!" She punctuates the threat with a slap across her ass, as she rubs and grinds her pussy into your mouth, reaching behind and pulling open her pussy as she covers you completely. "Take it," she demands, feeling you start to fade. She teases you about how quickly you've submitted. As you feel her thighs again begin to tighten and her grinding become more and more intense, your vision starts to go black. You hear her cum, loud and greedy, and you fade into darkness. As you fade, you hear her voice, giggling, still teasing as it all slips away
