Her eyes locked onto the veiny, throbbing cock, the slut can't resist the urge to touch, to stroke. She spits into her palm, lubricating her grip as she jerks him off with increasing fervor. Her wrist twists with each stroke, her fingers brushing against his sensitive underside. She can feel his pulse, his heat, his impending explosion. Her other hand cups his balls, gently rolling them, encouraging his release. The room is filled with the sound of her eager fapping, her heavy breathing, and his low, appreciative groans.
