I have to do my best relying only on my own strength. It’s always been that way

Souichi Hoshiura, worn out from working at a toxic company, ended up recuperating in the countryside.
Taking care of him is his uncle, Sisimaru Hoshiura, with whom he has been familiar since childhood.

Souichi thought he could relax and take it easy, but he can’t stop dwelling on past troubles.
He feels that Sisimaru’s kind words are just empty niceties, and pushes his uncle away, asking to be left alone.

Sisimaru was ready to become a dirty mama who even took care of his dick!
Despite being perplexed by the unexpected turn of events, his days are filled with intimate moments with the uncle he has always admired.

Let Uncle Mama heal your weary heart


Souichi Hoshiura【Top】

「Nobody really thinks about seriously helping me」

He was a working adult who worked at a toxic company. Every day, he returned home by the last train and was forced into a lifestyle without breaks on weekends or holidays. It took a toll on both his mental and physical health. He has since resigned.

Although a doctor recommended him to rest and recuperate, he didn’t want to be a burden on his father, who had single-handedly raised him. So, he consulted with his uncle, Shishimaru, and decided to live together in the countryside.

During his school days, he was a popular gay individual. However, since becoming a working adult, he hadn’t been romantically or sexually active. With a muscular physique due to his sports background, he never had trouble finding partners. Yet, he only had superficial relationships, always keeping a certain distance.

「Uncle Mama will definitely cheer you up!」

Soichi’s uncle. He usually works in the countryside managing rental villas. He often has to do physical labor, which has naturally led to him having a buff physique. Contrary to his appearance, he’s excellent at household chores like cooking, laundry, and cleaning.

He’s deeply concerned about Soichi, who’s been worn out from working at a toxic company. He genuinely wants to help and support him in any way he can.

He’s straight and has never had any romantic experiences with men. While he has dated women, he’s often been turned down for reasons like, “He’s nice and kind, but he’s just not exciting.”
