When her son's friend comes to stay the night, Miina's mom can't help but get turned on by staring at her breasts with naughty eyes. She purposely barges into his bath and pretends to wash his erect cock, grabbing it and making him stop just before climaxing again and again, enjoying his reaction. While her son is asleep, she invites him into her bed and gives him sex instruction using toys. The naughty kid's sexual desire exceeds Miina's imagination, and he roughly messes with her pussy, making her cum over and over again with his energetic cock.
