"My daughter-in-law needs a massage..." murmured my father-in-law suddenly. Since his retirement, he'd been lazing around the house all day, yet now he seemed to be plotting something. Matsuri felt a little uneasy, but upon recalling he used to work as a masseur, she figured it would save her a trip to the salon—and with her daily chores leaving her exhausted, a little pampering might do her good. So she agreed to let him massage her. But her father-in-law's skills were far beyond ordinary. With years of experience and an uncanny touch, each stroke of his hands heightened Matsuri's sensitivity. Her body grew increasingly responsive, and the idle old man's daily routine soon transformed into a life filled with pleasure as intense as sex itself.
