Joyful

"Teacher!" Yui calls and smiles at me in a friendly way since I saved her when she was being molested on the train a few weeks ago. I always try to control my libido, but it's really hard. One day, Yui slips off the top of the stairs. I try to catch her, but we both fall down on the floor.... "Are you alright...?" I hear a beautiful voice.... Yes, it's Ayano, a sick-room doctor. She is very popular among male students because she's got big breasts, an hourglass waist, and a beautiful body shape.... Yui and Ayano.... They gradually change my life.... Also, Ayano sometimes speaks to me purposefully. A small mystery. What's Ayano's intention...?
