Lilith Morningstar, the sultry, tattooed stepmom, notices Johnny's glazed-over eyes during their study session. Following his gaze, she finds him staring at her generous cleavage spilling out of her top. Catching him mid-stroke, she smirks, "Is this what you're studying, Johnny?" She straddles him, her massive tits in his face, and grinds against his stiff bulge. Johnny, now fully erect, can't help but masturbate openly, his pre-cum soaking his pants as Lilith's warm breath tickles his ear, promising a forbidden, flesh-and-blood study guide.
