They debate

"It's a tiny little thing!" Luvia commented, pointing with her finger. It was the truth.

But Rin? She went wide-eyed. She gasped. Rin even put a hand over her mouth in shock. "S-so big!"

Both Luvia and Shirou looked at her like...what? Really? Big?

See, Rin was a virgin. Rin read textbooks. She had zero standards to compare her crush to and thinking the best of him, believed him to be big. A hung stud. Talk about delusion. Suddenly, Rin and Luvia were at odds again.

"Ha? Are you crazy? I _love _Sherou but you must have low standards if you believe that's big!"

"S-shut up! It is big! I-I mean, how much bigger would you want it inside your...." Rin trailed off, blushing a bright red.

Luvia rolled her eyes and shook her head. Her boobs jiggled as she crossed her arms. "Japanese people...always of the low standard."

"What did you say!?"

"I said what I said. Sherou has a tiny cock!"

"He does not!"

"Does too!"

"Does not!"

Luvia made a small penis sign with her index finger and thumb. She showed just how small Shirou was. "It's hardly three inches!"

Rin fumed. "T-that's close to average!"

"Close but not quite!"

"It is!"

"I said it's tiny!"

"Big!"

"Tiny!"

"Big!"

Shirou assumed Rin had never seen a penis before because, well...the results were clear. The answer was just plain to see. Shirou Emiya had a small cock. Yet she insisted otherwise. Rindebated with Luvia despite her flushing red face and tsundere tendencies.

Maybe this was the true power of the tsundere. Claiming your crush has a big dick even though they didn't.

"Rin..."

Shirou could only smile and laugh quietly. At least one thing was clear: Rin Tohsaka would ALWAYS side with Shirou Emiya. No matter the timeline and no matter the circumstances. She was there for him.
