Premature ejaculation

Shirou, the beloved hero of Fate, stood there with a sheepish expression on his face, his tiny erection throbbing pathetically.

That was when he tensed up. That was when his balls suddenly felt full.

Fuck. No...no, no, no!

He didn't touch himself. Those boobs, big and small, and their little bounces as they spoke....it was too much. "Ngh!" Spurt! A small amount of clear liquid shot out of his cock, landing with a soft splash in the water around him.

"Shirou...!"

Spurt, spurt!

Two more spurts of cum. Luvia and Rin watched. For such feeble balls, it made sense. For a man whom they were crushing on...

"Sherou...? T-this is..."

He didn't want to open his eyes. He didn't---!

"Hohhoho! He came early!"

"Emiya came because of us...cute~"

Then they burst into laughter. Shirou's dick wilted. Dammit.

But the laughter wouldn't stop. Fuck. Fuck, fuck, fuck! His heart was racing faster than ever before. His cheeks were tomato red.

This sucked! This went beyond simple humiliation.

As Shirou caught his breath and put a hand to hide his dick, Rin decided to tease him further. "Well, looks like someone couldn't wait any longer," she said with a mocking tone, stepping closer to the tub. She glanced down at his hidden cock and giggled. "Come on, Shirou, there's no need for that. We've already seen your little thing."

"Emphasis on little. I don't think you could find one as small as that in Europe," Luvia remarked.

"Or in England," Rin added.

The two were in agreement. Rivals had become friends. All because of a hero's small dick.
