Airi, the wholesome ex-girlfriend from my youth, reappears as an aggressive, sexually confident gal. Back when we were students, our relationship was completely platonic—we never had sex or even kissed. Years later, a chance reunion during a trip home reveals how dramatically she has changed. She is still in love with me and wildly turned on, using sweet, dominant techniques to make me cum again and again until my balls are drained and I am completely spent. One round is nowhere near enough for her.
