Tsun M Gyutto Shibatte Shidoushite ~Tie me up tightly and teach me~

Original Name: ツンえむ！ 〜ぎゅっと縛って指導して〜
Summary: ❤️❤️❤️ “I’m asking you what this is, I…!!” On the bed in my room, erotic books and AVs are lined up in a chaotic manner, as if it were a public execution. Something for SM play lovers. It was a big fuss about people being tied up, beaten with whips, and muzzled. “Why are you an SM?!” The person in front of me who was angry was Saki…my student and girlfriend. She was trembling, thinking that she was about to be beaten…for some reason, Saki held out a towel to the tip of my nose. Instead of her fist, she used a towel… After glaring at me, my heart pounding, wondering what kind of pain I was going to be inflicted, Saki collapsed onto the bed. “Hurry up and do it… tie me up with that towel…!!”… Huh? Um… what? what? ? Saki suddenly assumed a strange posture and turned bright red as she gave an order. “Isn’t this what you wanted to do?! Tie me up and have sex with me…!!”
