Step sis teases all morning in tiny short skirt, no panties, bending over the couch “looking for the remote.” I finally snap, pull her over my lap, flip the skirt up and slide raw into her tight ass in one deep thrust while she gasps “yes, finally.” Couch cushions sink as I pound steady and hard, her skirt bunched at her waist, ponytail bouncing with every stroke. She pushes back greedy, moaning “deeper” loud enough for the neighbors to hear. She cums shaking, ass pulsing around me. I grip her hips tighter and unload thick ropes deep inside her pulsing hole, cum dripping down her thighs onto the fabric while she collapses laughing “worth the tease.”
