Horny and alone, a young man retreats to his room, closing the curtains but leaving a tantalizing gap. He begins to stroke his rock-hard cock, his moans filling the room. Unbeknownst to him, his mother-in-law is outside, her curiosity piqued by the strange sounds. She spots him through the window, his hand moving furiously, his body tensing as he nears climax. She watches, entranced, as he spurts his load, his cum staining the sheets.
