Half-Naked Swimsuit School I'm A Transfer Student Who Gets A Hard-on, And Big-breasted Lascivious Miss Seimiya Is Worried About Me, So I'll Be Fine For The Next Class! Niiai Kiyomiya

I had to transfer schools due to my parents' circumstances, and it was my first day. I nervously entered the classroom, and it was a normal class with cute girls. But once the opening ceremony was over, everyone suddenly changed into swimsuits, and I was made to change too, with classes starting while we were still in swimsuits. I couldn't stop my boner from the unexpected situation and the sexy swimsuit figures. Seeing me like that, Miyamura-san helped me out by jerking me off. From that day on, a lewd and pleasurable school life began, where I'd get hard during class and have sex during breaks.
