HZGD-335 My father-in-law was a big sugar baby who taught me about pleasurable sex... My masochistic wife, Hinako Matsui, became a human toilet, squirting and wetting herself uncontrollably.

Hinako, a young wife who married her husband, was secretly saving money through "sugar dating" because they didn't have enough funds for their wedding. Some time later, she met her husband's parents for the first time, and her father-in-law turned out to be a wealthy sugar daddy with incredible skills. From that day on, she began having an affair with her father-in-law. His intense and persistent torment, so different from her husband's, awakened her masochistic side, and she climaxed repeatedly. "I'm sorry, darling... I'm being trained as your sex slave again today..."
