A female classmate from the same university who feels like a guy friend and doesn't require much effort. As we were playing as usual, I unexpectedly saw her underwear and her body was surprisingly erotic!? The classmate girl, unable to resist my growing desire, stared at me with a rarely seen maidenly expression... Before we knew it, we were going at it all night until morning! From that day on, as the classmate girl became more and more feminine, the excitement didn't subside, and the two of us, who had been in a relationship up until then, started to engage in increasingly erotic activities as if our previous relationship had been a lie.
