While my wife, a career woman, was away on a business trip, her mother, who is overly busty, came to take care of her. Her magnificent breasts, visible even through her clothes, shook violently every time she moved! I couldn't take my eyes off her busty, ripe body that was full of eroticism as she unconsciously seduced me, and my crotch was constantly horny and ready for battle! I got carried away and went to peek at my mother-in-law taking a bath, and she provoked me by showing me her masturbation, and even had sex with me and came inside her!
