My admired senior, Ms. Fujimori, has dated department manager Shimizu since my student days, and I have always envied him for having such a beautiful girlfriend. One night Shimizu skips a drinking session at her home, leaving Fujimori angry and extremely drunk. I cannot resist touching her as she sleeps with her ass exposed, and she responds eagerly enough for us to have cheating sex with a creampie. I obsessively lick the asshole her boyfriend has never touched, making her tremble, squirt, and cum again and again until her pent-up frustration gives way completely to pleasure.
