Guilt-ridden milf can't resist her son's massive cock. She sneaks into his room, finding him asleep, his huge member straining against his boxers. She can't help but touch it, feeling it grow harder under her soft caress. She strips off her robe, her full breasts spilling out. She mounts him, guiding his massive cock into her tight pussy. She rides him slowly, her eyes closed, her body shuddering with pleasure. She's about to cum, her son's cock filling her completely, when she hears her husband's voice. She freezes, her body tense, her heart pounding with fear and lust.
