Due to my parents' arrangements, I had to transfer schools and it was my first day. As I nervously entered the classroom, I found a normal class with cute girls. However, after the opening ceremony ended, everyone started changing into swimsuits, and I was made to change as well, starting the lesson in just a swimsuit. Unexpected development and erotic swimsuit appearance made it impossible for me to control my erection. Unable to bear seeing that, Kiyomiya gave me a handjob. From that day on, I started having an erotic and pleasurable school life, getting hard during classes and having sex during breaks.
