The MILF's eyes widen as she sees her son's massive erection straining against his jeans. Her mouth waters, and she licks her lips, her pussy clenching with desire. She knows she shouldn't, but she can't help herself. She needs to feel that big cock inside her. She approaches him, her large tits bouncing, and drops to her knees, unzipping his pants to reveal his throbbing member. "Mom, are you sure about this?" he asks, his voice barely above a whisper. She just nods, hungry for his cock.
