What is this Stain on your Pants Johnny?

Johnny's been going through hell lately, so he jacks off like it's his full-time job. Leaves the mess every time. Pants get tossed wherever. His stepmom Grace pulls a pair marked with that white crust and grins. Knows exactly what she's holding. Old jizz. When she confronts him he stumbles through excuses about “issues,” but she doesn't buy a word. She crosses the room, drops the pants on his lap, and says she’s fixing his problem the fast way. Drops to her knees, frees him, takes the whole length in one smooth motion. No patience for foreplay, just greedy mouth and wet sounds. She stands, peels off what’s left, pushes him back on the bed, straddles, and sinks down until he's balls-deep. Rides hard, tells him to use her, talks filthy while her tits bounce in his face. Wet slap of skin echoes. Each thrust stronger, deeper. She squeezes tight around him, rides until he's shaking, until she floods his cock with her own mess. When he finally blows she keeps grinding, milking every drop. Morning wood already accounted for, cum guaranteed inside her every day from now on.
