Shinji ended up living at his brother's place. The one who greeted him was Fuka, his brother's naturally busty wife with K-cup breasts. She rested her chest on the table and wiped spilled tea with her underboob, unknowingly driving Shinji crazy with her seductive allure! Moreover, even when his brother was sleeping next to them, she would press her marshmallow-like body against him, fully embracing her maternal instincts… A clumsy, kind-hearted big-breasted sister-in-law makes me weak in the bones in this taboo 114 minutes!
