A gray-haired MILF has mastered the 69 position! She sucks on a limp cock—it swells in her mouth and shoots its load down her throat

A mature woman discovers Newton’s laws as they apply to a penis in the 69 position. The action (her hands-free, deep, and wet sucking) generates a reaction (a rapid rush of blood and the growth of the limp shaft to threatening proportions right inside her mouth). The friction of her tongue triggers the secretion of saliva—as copious as a Saint Bernard’s drool, trickling down the shaft toward the balls. The climax is the law of conservation of energy: all the accumulated power bursts forth in a torrent of semen, which, thanks to a precise calculation of its trajectory and the accessibility of her throat, bypasses her teeth and tongue, heading straight for her esophagus. Theoretical physics has never been so practical—or so wet.
