In her dimly lit, cluttered workshop, a mature woman, a milf with a penchant for control, sets up her latest creation: a homemade cock pump. With a gleam in her eye and a smirk on her lips, she strips off her overalls, revealing a lacy lingerie set that accentuates her curves. She lubes up the pump's shaft, her fingers slick with the gel, before straddling it, her pussy lips parting to accept the cold, hard plastic. She turns the pump on, feeling it pulse inside her, stretching her, filling her. Her moans fill the room as she rides it, her tits bouncing, her hips grinding, until she finds her release.
