It was a summer day when I had crazy sex with a sweaty apartment wife who unconsciously invited a man.

One summer day. Hikari, who lives on the same floor, stood in the hallway looking in trouble. When I called out to say hello, the fan apparently wasn't working well. "Shall I take a look?" I took it with a light heart, thinking it was kindness... When I think about it, my husband was away from work, and it was a room in a humid apartment complex. Hikari's open chest...the dripping sweat was strangely sexy...I had some weird expectations.
