Since moving into the house next door, I've been captivated by my neighbor sister's megaton hips. The curve of her ass beneath her tight skirt instantly caught my eye. When she appeared without panties, teasing me further, I couldn't resist inviting her into my room. "You really love big butts, don't you, you pervert?" she taunted, then pinned me down with her voluptuous hips. Overwhelmed by her force, I was pushed onto my back and immediately attacked. She pressed her ass hard into my face, smothering me. Riding me in a pounding, jackhammer cowgirl rhythm, she took creampie after creampie inside her. Her relentless grinding and the hypnotic sway of her big ass kept me constantly erect. I never expected things to turn out like this after moving in next door. Finally, I cried out, "Ah, no, I can't hold it—I'm cumming again!"
