Mio Ishikawa, already incredibly sensitive, is ordered to abstain for nearly a month: no sex and no masturbation. She is teased with live sex and forced porn viewing until she is nearly at her limit.

Rapid pounding leaves her weak at the knees, convulsing and unable to stop cumming through three intense sex scenes.
