Today is the welcome party for new members of my drinking club. I ended up drinking at my senior's house, but I was the only girl there. But I thought it would be okay because all the seniors are nice people, and that was my luck. Gradually, the atmosphere became erotic, and I ended up having sex with the seniors. I knew it was wrong because they had boyfriends, but when they touched me, it felt good and I couldn't help it... Sorry, boyfriend...♪
