After marrying off her daughter, Kaoru now lives with just her husband. Although they love each other, he has erectile dysfunction, and recently, they've been truly neglecting intimacy; Kaoru's sexual frustration had reached its limit. Just then, her daughter's couple bought a second-hand house and invited them over to celebrate and stay. It was quite a nice property, and both Kaoru and her husband were happy for her daughter's new home. Amidst this, Kaoru accidentally sees something shocking from her son-in-law. In the middle of the night, as Kaoru heads to the toilet, she notices her son-in-law fidgeting with something in bed, then releasing a white fluid. For a moment, she didn't understand what was happening, but she realized it was semen released from her son-in-law's self-pleasure. Unlike her husband's weak ejaculation, this one drew an arc with force, making Kaoru's womb tingle. The next day, leaving Kaoru behind, her husband and daughter went out, and her son-in-law was dozing off in the living room. Kaoru glanced around furtively before approaching him. She gently pulled down his pants, feeling his robust penis through his underwear. Suppressing the urge to pounce on it, she slowly and gently stroked it. Instantly, it grew larger and harder. Unable to resist, she took it out from the gap in his underwear and moved it up and down lightly. Her son-in-law's penis became even stiffer, and Kaoru drooled over it, stroking it smoothly. She couldn't help but take the hard erection into her mouth, savoring it as she sucked. In a moment of excitement and joy, Kaoru felt her son-in-law's penis release a large amount of fluid into her mouth. The shock in her throat and the male scent spreading in her mouth brought Kaoru to her own climax…
