My husband hasn't been with me for the past few months. - Hibiki suddenly saw her brother-in-law's big penis at her husband's parents' house and couldn't get the wonderfully towering cock out of her mind... - Hibiki and her husband return home to their husband's Otsuki family and hear from their brother-in-law that their parents are on a trip. - Hibiki had never met her brother-in-law before due to circumstances, but she was relieved that he seemed like a kind person. - Although her parents were not home, her husband told her brother that he would stay with her for a while, and the three of them began living together for a few days. - Hibiki visits her brother-in-law's room while he is taking a nap, and ends up reaching out to touch the bulge in his crotch that looks like it's about to pop out. - The penis that appears is not fully erect, so I can't help but take it in my mouth. - Hibiki couldn't stop sucking on his ever-expanding cock, which felt like a deadly weapon.
