Sanae is a slutty high school girl who doesn't even cry out in protest when she is molested, instead secretly enjoying the thrill. One day, a teacher at school forces her to do it and uses it as an outlet for his sexual desires. The perverted teachers who witnessed this then treat her like an obedient masturbator. She is given the ultimate K-cup titjob, relentless nipple play, a reenactment of the real masturbation she does every night, and is made to juice her pussy with hard pistons and five creampies, turning her into a sex slave for the teachers!
