Unbeknownst to her son, his stepmom, a busty, mature MILF, is bent over in the kitchen, her plump ass on full display. He approaches, his cock hardening at the sight of her ample curves. He grabs her hips, positioning himself behind her, and without a word, pushes his throbbing dick into her tight, unlubricated asshole. She gasps, surprised but eager, as he begins to pound her, his balls slapping against her pussy. She moans, her fingers digging into the countertop, as they fuck, him filling her ass, her juices dripping down her thighs.
