I joined a lingerie manufacturer and got my first chance to go on a business trip. The destination was Okinawa. And I was going to be with my boss, Rui, who I admire and who is good at her job... What? The plane was delayed due to equipment trouble caused by the heatwave and I couldn't go home? I managed to get a place to stay and ended up alone with Rui in a shared room, but the air conditioning was broken and I could see her beautiful body, wet with sweat. She even teased me by showing me her bare skin, so there was no way anything would happen in this situation... We had creampie sex over and over again until the morning.
