Introduction
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.
But!
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♡
