LULU-391 While her husband is away on a business trip, Reika Takeda, a curvy, busty wife with a naturally alluring underarm, unintentionally tempts her lecherous father-in-law, then uses a playful underarm embrace to put his overexcited advances in check and bring him to climax.

For several years, he had been living with his son and daughter-in-law, the three of them sharing a home. With his son busy all the time and his daughter-in-law’s striking figure impossible to ignore, he struggled to keep his feelings in check.

One day, his son had to leave on a business trip, leaving him alone with his daughter-in-law for several days. While cleaning, he became flustered by the casual glimpse of her underarm showing from her sleeveless top and, before he knew it, leaned in close. Though she was surprised, he found himself captivated by the moment and became unable to forget it.

From that day on, he was unable to shake the memory of that intense feeling and became completely fixated on the sensation, falling deeply into his obsession.
