One day, while Aki was cleaning the front of the house, Koji, who lives nearby, came to greet her. Koji had gone on a trip for a training camp and said he would bring her a souvenir later. It was a hot and humid day, and Aki took off her bra and panties and continued cleaning. She forgot that Koji was coming and fell asleep on the veranda. When Koji went to visit Aki with the souvenir, he found Aki sleeping without panties... Koji was about to leave the souvenir behind, but he decided to go back to Aki's place just to have a look...
