Recently, I confessed to the incredibly cute Tsubomi I met at a mixer, half-expecting rejection—but to my surprise, she said yes. Now we're living together, and I, who once had no luck with women, am finally living the dream as a total winner. But a nasty senior from my part-time job found out about Tsubomi and started visiting her at our place while I was away, knowing she's too kind-hearted to refuse. I had a bad feeling, but one day, Tsubomi suddenly stopped coming home. A few days later, I received a video from that guy—and was utterly devastated. In it, Tsubomi appeared completely transformed: far more sensual and mature than ever before, her body and expression dripping with lewdness, shaking me to my core.
