In the throes of self-pleasure, the stepson's door creaks open. In walks his stepmom, her eyes locking onto his throbbing cock. She licks her lips, her heart pounding with taboo desire. She moves towards him, her large tits swaying, and takes him into her mouth. She sucks him with a ferocity that belies her mature, refined demeanor. She moans around his cock, the vibrations sending shivers down his spine. She takes him deep, her nose pressing against his abs, before pulling back, her lips glistening with saliva and pre-cum. She strokes him with one hand, her other cupping his balls, before finally, he can't hold back any longer, exploding in her mouth, his cum filling her, spilling from the corners of her lips.
