Kaoru, an adult senior of indeterminate age, has practically moved into our college clubroom. She sleeps there whenever she wants, never seems to attend class, and has repeated so many years that nobody knows her grade. We get along, and I secretly enjoy glimpses of her cleavage and underwear until an erotic conversation prompts her to offer me her pussy after learning I am a virgin. I have no reason to refuse, and soon we spend day after day sweating in the room with no air-conditioning, fucking as her full breasts bounce. I think this strange routine will continue, but then something changes.
