Eric's eyes widen as Kate, his stepsister, struts into the room in skin-tight leggings, her juicy pussy and bubble butt clearly outlined. She teases him, rubbing her pink slit through the fabric, before pushing him onto the bed, missionary style. Eric's thick cock strains against his pants as Kate grinds against it, her breaths hitching. She strips off her leggings, revealing her tight, wet pussy, and mounts him in doggystyle. Eric's cock slides in easily, and he pounds her until he can't hold back, pulling out to cum all over her leggings and pussy.
