The order among students in school life that everyone feels once. These days, it's almost impossible to overturn a once-established hierarchical relationship, called the school caste! I'm the lowest-ranking person in the world, and I look like a cow, and the only thing I have to offer is my libido. Even though I look like I have a sexual desire, it was only useful for masturbation, but I was nominated as a friend by Rima, who is the highest caste! Turned into a handsome boyfriend with a weak libido and turned into a dildo exclusively for Rima! Shady man's windfall sex spring!
