The busty girl who came to tutor my son was my ideal type! She was always in agony every time she came to my house for class, and I couldn't stand just looking at her, so I gave my son a sleeping pill and the tutor a drink laced with an aphrodisiac, and it worked wonders! The aphrodisiac made the tutor horny, and she couldn't help but want to have sex, so she turned into a nymphomaniac, devouring my sleeping son's dick! I stuck my rock-hard dick into the tutor and fucked her hard from behind!
