A Virgin's Sex Training With a Yakuza

Overview

If you can't pay your debt, you have to pay it with your body. In order to pay the debt left by my late parents, I ended up working at a high-class soapland run by a yakuza...!! However, since I was a virgin, I didn't know anything about soaplands, so Mr. Katagiri, the yakuza, taught me different soapland techniques I could use. Mr. Katagiri pushed me down and put his finger inside me. Even though I was a virgin, I came immediately...!! I was not used to this pleasure, so I fainted every time we did it! I was trying to get used to it with Mr. Katagiri, but his kiss alone made my body feel like melting... (Source: MangaPlaza)
