Sweaty, closed-room sex filled with breath and heat that can't be escaped so hard

Mako is a married woman who has been married for four years. One day, my husband brought his young subordinate, Shoji, to his home. The last train is gone, so I decided to stay overnight, so when I opened the door to stop by the bathroom, I saw Mako in her underwear. "I'm being watched...I'm a mean person who wants to make a simple-looking guy bother him..." Unable to contain Shoji's desire, he was forced into his futon that night and was sought for his body. That day, she falls into sex where she finds each other's dicks, in a close space that is close to her husband, sweating, and so much so that she can get her dicks...
