[Rei blushes, and it's hard to hide in this position that he's starting to get hard again already. Rin is really persuasive, and really sexy underneath him like this. Normally this is where he would avert his eyes, but he doesn't.]

At least there will be soap involved.

[He leans down to kiss Rin's lips one more time (it's easy when one's as flexible as Rei is) before sliding off him and getting up, stretching to get the kinks out of his back and arms. Also because it makes all his muscles flex, but that's not his primary motivation (supposedly).]

If you really think it's pointless, we could always go cook instead. But I thought you might want a shower first.
