Single mother gets fucked and sleeps with her long-lost ex-husband - Sumire Mizukawa NGOD-086

I'm Keisuke, a kindergarten teacher. This year, in the Kirin class, there's a mischievous boy named Takamori, whose guardian is a single mother named Sumire Mizukawa. I, being single, have fallen for her—a beautiful and quirky girl. Every month, I set aside a small portion of my salary to provide financial assistance to her family.
