My husband has no interest in me. Even when we go out for drinks, he only stares sourly into his glass before heading home alone. Left behind, I meet Yuzuru, an adult student drinking at the next table. We grow close and eventually begin an affair. After he gives me a spare key, visiting his apartment becomes the highlight of my days. Whenever he returns, I welcome the vigorous young adult man’s appetite as many times as our limited time allows, continuing to take his creampies until graduation.
