Once Erwin figures out what Levi wants, he helps as much as he can, dealing with buttons and belt buckles as quickly as possible. It's always a little difficult to strip down when he's bent forward to kiss his husband, but he can make it work.

When Levi pulls away to step into the shower, Erwin sees where things are going. He finishes with his few remaining scraps of clothing, and then starts fumbling with the straps across his chest that hold his arm in place.

"As quick as I can." He's had some practice by now at getting his arm on and off in a hurry, and can manage the buckles with one hand. The arm disengages from his stump with a soft hiss and a crackle of electricity, and Erwin lays it carefully on the bathroom counter. He rolls his shoulders, taking that second to adjust to his changed center of gravity, then steps into the shower with Levi. The water sluices off him, and Erwin arranges himself so he's not blocking all the water stream.

He's down to one hand now, but it's enough to put it on the small of Levi's back and pull him in close for another kiss.
