Mery's innocent massage turns heated as her stepson's big cock grows hard between them. She can't help but stroke it, feeling its thickness in her hand. His lustful gaze on her big ass ignites her desire, and she straddles him, slowly sinking down onto his massive dick. She rides him, her pussy stretching to accommodate his size. Mery's moans fill the room as she grinds against him, her clit rubbing against his pubic bone. He grabs her hips, slamming her down onto him, his cock filling her completely. She wants him to cum inside her, but he pulls out, spraying his hot load all over her, marking her as his.
