In this naughty nod to Evangelion, a horny student struggles with calculus, his forbidden desires overwhelming him. As he stares at the equations, he imagines Asuka's inviting pout, his cock twitching. He tries to resist, but the allure of the neon digits is too much. He strokes himself furiously, his grunts echoing in the empty room, until he reaches a climax that leaves him panting and spent, his notebook filled with his lustful, mathematical fantasies.
