My perverted S-type teacher Mr. Hasegawa has been masturbating every night while fantasizing about binding his student Himekawa. One day, he invites her to his home under the guise of academic guidance and intentionally leaves rope where she can see it. She notices it out of the corner of her eye, confirming his suspicion that she shares his bondage desires. He skillfully coaxes her into submission, initially resisted by her but her pussy is already soaking wet. Through his 'punishment', her deviant side accelerates even further.
