[Mogudan] Tatsumaki-ppoi Tsuma (One Punch Man)

A busty Tatsumaki-like wife with massive breasts and a plush, heavy ass moves with her bespectacled husband to a very quiet rural house, a new home that quickly becomes a stage for forbidden tension with his muscular younger brother. Presented as the diary of a wife that looks like Tatsumaki, the affair builds from secret staring and stolen glances while watering plants to breathless hidden sex — groped bare breasts during laundry, a teased miniskirt, and raw, dripping encounters while her husband waits just on the other side of the door. She smiles gently to see her husband off, then confesses how thrilling it is to be a naughty wife who keeps cumming for her brother-in-law whenever her husband won't find out.
