This hentai OVA follows three big-breasted high school girls who have developed an intense craving for middle-aged men's cocks. Vice student council president Sana Miyamoto teases the school principal during a "stretching session," leading to passionate body touching that makes her squirt. Chinatsu Kogure innocently gives her uncle a massage in her room, only to drive him wild with her naive movements. Meanwhile, Kyoko Tazawa boldly shakes her ass at her teacher during after-school supplementary lessons, openly inviting him to take her.

In the second episode, the three girls meet up with six older men they connected with online and rent a room at a hot spring inn for a wild group session. Sana serves the principal with a devoted blowjob, Chinatsu gets pounded hard by her uncle until she squirts repeatedly, and Kyoko is tormented to climax with a vibrator before all three girls have every hole filled by the men's cocks. Their delighted, ahegao-filled moans echo through the inn all night long as they fully indulge in their addiction to oji-san dick. Full of big tits, sloppy oral, squirting, and multi-partner action.
