Eren makes noise practically the whole time, unable to keep his mouth shut, unable to just be quiet, too filled with need and sensation. Reiner works him over the whole time. He could keep going, push Eren harder, drag the sensation past where it would feel good. But he doesn't. True to his word (I've got you), he doesn't push it any further than he has to.

His hand joins Eren's on his cock but it doesn't take long at all.

Eren can count on one hand the times anyone has ever called him beautiful. Actually this is maybe the second time ever that he can recall. He would scoff or roll his eyes or try to play it off in another situation. After all of this, it makes his breath hitch. Reiner says his name the same way he says beautiful and Eren will pretend up and down for weeks that it doesn't affect him but it does. Damnit.

Eren holds on to Reiner's shoulder like a lifeline, like he's afraid he'll lose himself if he lets go (he might). For a long moment afterward they're just there like that, together, breathing. He should let go. He should move. He should…do anything, but he still doesn't. When they move, this will end, and they will be enemies again and who the fuck knows what else. For now, they can just be two boys, together in the rain, alive and breathing, undeserving of it but still here nonetheless.
