"One's Appearance Reflects One's Mind" The Refined Male University Student Turns into a Cultured Lust Beast Once Desire Awakens

As the saying goes, "One's appearance reflects one's mind," but in the context of being overwhelmed by lust, this phrase can completely shatter a person's image. At least in my years of experience with training, I've encountered many "refined lust beasts," and today's protagonist is one of them.

The male university student experiencing training for the first time appeared polite and cultured during the meeting, but once the desire switch was flipped, he began uttering all sorts of lewd words. I kept reminding him to keep his voice down to avoid complaints from neighbors, but he couldn't stop his urge to ejaculate, repeatedly begging, caught in the conflicting desire of wanting to cum but not wanting to finish too soon.
