"Prompto would explode." He was already exploding without a demonstration. Gladio rolls his eyes, stuffs half a twinkie in his mouth and waits for Prompt's protests to quiet down before he speaks again.

"You'd never even considered dudes until I kissed you, bullshit." He lifts a hand to stop a further outburst. "Look just... I know how easy it is to get caught up in a new relationship and get carried away. Just do me a favor and wait until we end up somewhere we can find something at least halfway decent for lube before you two try fucking? The lotion and shit we've got here is old as balls and not gonna cut it."

He does not want to have to deal with the aftermath of them trying to have sex and not using enough lube and someone ending up torn when there's no way to fix things.
