UMD-1010 My younger sister came to Tokyo for a company event with a coworker who is her boyfriend, but they couldn’t get a business hotel, so they stayed in my room for three days and two nights.

My younger sister came to Tokyo for work with her boyfriend, who is also a coworker. Because of the impact of inbound tourism demand, they couldn’t get a hotel in the city center, so they ended up staying in my room. Then my sister, who had been sleeping next to me, moved over to where her boyfriend was sleeping in the living room. Wait, what?! Before I knew it, they were getting intimate in my room. I pretended to be asleep, but it went on and on. Wait, how long is this going to last?!

The next day, I gave my sister a serious warning. When I asked her about it, she said her boyfriend had a very strong sex drive. She apologized and asked if they could stay one more night because they wouldn’t be doing that again. My sister left for work first, and her boyfriend stayed behind in the bathroom. To my shock, he was pleasuring himself in my house. I yelled at him. He apologized while kneeling naked, but he was still clearly aroused, and things naturally escalated from there.

That evening, my sister came back early after a staff celebration and was already completely exhausted. When her boyfriend returned with souvenirs, they ended up getting close again.
