Raju opens his mouth, his first instinct, too, to make some decision about it, authoritatively. He lets out a brief, amused noise instead, reaching out to capture Francis' hand before it can make Raju's stomach twitch again, skin no less sensitive just because Francis has stopped actively trying to tickle him. Francis admitting he doesn't know much about this makes it easier, for Raju to admit it too. Surely it should have the opposite effect but somehow it doesn't. Somehow Francis not knowing doesn't mean that Raju has to guide him anywhere.

"Ah..." He thinks over it, shakes his head. "Or soap, maybe?" he suggests and laughs a little, feeling ridiculous and tightening his grasp on Francis' hand to compensate. "We have enough of that too. Unless we'll need a lot of it."

He can do all these things with Francis, both clothed and completely bare, he can say all manner of filthy things, but for some reason this is the thing that sends a flush into his cheeks. There's something about mixing the everyday with the erotic, feeling this way and talking about the practicalities of the proper material and their supply of it. He almost can't tell it from all the other warmth in him, he feels the colour gather under his cheeks with a different kind of heat.
