"I sweat a lot at work, but sometimes I want to sweat it out with sex." Gym instructor Junko Momoi strips off in front of the camera for the first time and has sex for the first time! When she takes off her clothes, she reveals a super slim body that doesn't look like she's 44 years old! She's not going to show it to anyone, and she's not going to let anyone touch her, so she's too good to let it sleep, and she's being tormented by this wonderful body, which is too good to let sleep, and she comes over and over again. All three scenes are great and intense!
