Susan, the busty, experienced stepmother, can't keep her hands off her stepson, Machine. Today, she wants more than just a stolen glance. She corners him, her voice husky with desire, "Machine, I need you to lick me, baby. Make me cum, and then, I want you to cum inside me. Can you do that for mommy?" Machine, flustered but excited, nods. Susan guides his head between her legs, moaning as his tongue finds her clit. Once she's writhing with pleasure, she mounts him, riding his cock until he explodes inside her, satisfying her cheating, mature craving.
