Exclusive actress Ai Sayama finally appears in the topical series that stimulates a woman's new erogenous zone [Spence mammary gland] and sprinkles it! The Spence mammary gland is, so to speak, the G-spot of the breast. She didn't trust her at first, but she was incontinent because of her intense pleasure! "Don't use it !! Teacher! I'll get it again !!!", even though it was my first time, I got excited many times and at the end I got into a state of absentmindedness while cramping. Please enjoy the unprecedented climax of exclusive actress Ai Sayama.
