Mion and Hana are married women who are not having sex with their husbands and are overwhelmed with their bodies and sexual desires. They are seniors and juniors at work. In order to release their daily desires, they go on a hot spring trip to hunt for men! With their impressive, plump, busty bodies and overflowing sexual desires, the two reverse-pick up male customers and part-time workers at random! They sandwich them between their double busty breasts, force them to get an erection until they're satisfied, and shake their hips wildly! Now that they're free, they're attacked by an uncontrollable slutty wife and have their sperm squeezed out in a reverse sandwich sex session!
