Once Aziraphale recovered enough to hide his wings, he used the wheelchair and a fresh sheet to smuggle Crowley into a non-tainted apartment.
"Whose flat is this?" asked Crowley as Aziraphale helped him into bed.
"It belongs to Mr. Robert Green. He's a truck driver who rents the studio mainly so he can have an address to mail things to. Mrs. O'Malley said he's in Germany right now so we shouldn't have any interruptions. Do you want pajamas?"
"Is that a tick question?" Crowley asked. Aziraphale didn't answer. "Just get in bed," Crowley said.
Aziraphale took off his coat and slid under the covers with him. Crowley was hot to the touch. Even the short journey from the other down the hall had taken its toll on the demon.
"I think there may be a way to get your strength back," said Aziraphale.
"I have an old friend in heaven who collects historical demon artifacts. I remember him telling me about something that can help you."
"What was it?"
"I don't remember, but he said it could revive a demon even near death."
"Sounds great but, unless you're planning on taking me with you, I'll die before you get back. None of your love stuff seems to be sticking. I, however, have a much better idea."
Crowley slid a hand down Aziraphale's chest to his bare crotch.
"Wait, what are you doing?" the angel squeaked.
"Are you recovered enough to grow genitals?"
Aziraphale decided to become male. Crowley started to stroke him.
"How is this going to help you?" asked Aziraphale flustered.
"Remember when you said that giving me love was helping you recover? I don't have enough energy to have sex or even grow a dick but you do. If I get you off, it will probably help me. Now relax."
Crowley wrapped his fingers around Aziraphale's penis. They were warm and soft but his movements were rough and purposeful. Aziraphale moaned as Crowley pumped his hand up and down his shaft.
"Is it working?" asked the angel, his face flushing.
"Maybe I need to try harder."
Crowley sunk under the sheets. Aziraphale gasped as he felt Crowley's lips touch the tip of his cock.
"Wait! You don't have to—"
Aziraphale's words were cut short as Crowley's mouth closed around his dick. His cock grew hard as Crowley lavished it with his tongue. He took it deep into his throat and sucked hard. Aziraphale clutched Crowley's head as it bobbed.
"That feels…" Aziraphale moaned.
Crowley took it all in. He swirled his tongue around inside his mouth and held his balls. He licked the angel's hot cock from base to tip and around the head.
"Crowley," Aziraphale panted. "I think you should stop." He pulled away the covers. Crowley chuckled with his mouth full and sucked more. "I mean it," begged Aziraphale. "Please, I'm—"
The hint of panic gave Crowley pause. He withdrew his head but kept his lips on the tip and looked up at Aziraphale coyly.
"Is this really helping?" asked the angel.
"Immensely," Crowley said breathily, his lips brushing the head of the angel's cock.
Aziraphale blushed madly and pulled Crowley back up next to him. The demon didn't have the strength to protest. Aziraphale gave him a short kiss.
"I want to be able to see you."
"You could see me from down there just fine."
"Not good enough. You'll have to just use your hand okay?"
Crowley shrugged. "If you insist."
Aziraphale held onto Crowley as he stroked his cock. Those long fingers felt so good that his mind went numb. He couldn't think of anything else but the hot demon pumping him. Real lust from an angel was rare and Crowley was there to suck it all up. He had never done anything so wrong in his life and it felt fantastic.
"I'm gonna come," Aziraphale stammered
Crowley's eyes flared. He wanted so much to duck down again and drink it all, but he also wanted to see Aziraphale's face when it happened. He tightened his grip and slid a finger over the wet tip. Aziraphale groaned and kissed him. A jet of cum shot out between Crowley's fingers. The demon smiled. It had worked better than he had anticipated.
"You have to let me do that again," said Crowley licking the cum off his hand.
"Please don't," said Aziraphale. "I don't feel so good."
"Did I overdo it?" said Crowley concerned.
"No, I just don't think this is the best tactic. I'm sure that if I can just talk to my friend then you'll be able to recover fully."
"So no more sex?"
"I'd prefer not to." Aziraphale said as he gently pushed Crowley away.
"Oh, I'm sorry."
"No, it's okay. Doing this has helped you a lot right? Maybe now you'll be fine alone while I take a quick visit to heaven."
"Sure, I'll be all right here," said Crowley lounging back on the pillows. "You go get your thing and then everything will be just fine."
"Are you sure you'll be okay?"
"I'll be fine. Don't worry. I'm feeling a lot stronger already."
"All right then I'll be back before you know it."
Crowley was hot and not in a good way. Normally he wasn't bothered by temperature, but this wasn't a normal circumstance. The heat seemed to be coming from inside him and couldn't dare use any of his power to keep himself cool.
Damn it, if this goes on much longer, I'm going to start burning through the bed. Where is that stupid angel? I shouldn't have let him leave.
Crowley lay perfectly still. He had to focus on existing. Even with the extra power jacking off Aziraphale had given him, he was still struggling to keep himself from disappearing. It was just too easy for him to forget himself and drift away into a sleep that would never end. angels and demons aren't human. They exist because they know they exist, because they have been told they exist. The only way a demon can die naturally is by choice. In Crowley's situation, the choice would be made for him if he fell asleep without Aziraphale there to help him.
Where is he? I need him.
From far away, angels heard the call of someone in need. Aziraphale was the only one who listened. He said his goodbyes and rushed back to the borrowed room.
"Crowley? Are you—"
Even without an answer, Aziraphale could plainly see that the demon was not all right. He got to the bed as quickly as he could and tried to wake him up. The demon's skin burned his hands. He reflexively pulled away and healed his own wound before realizing that it wasn't a proper use of his still limited abilities at the moment. The power drain left him dizzy as he headed into the bathroom. He ran a towel under the shower and draped it over the wheelchair since it was too heavy to carry. He brought it back to the bed and covered Crowley with it. The towel dried almost instantly, sending steam into the air. Without thinking, Aziraphale released the power he had been using to stay human and diverted it all to restore his physical strength. His four wings bloomed behind him as he carried Crowley into the bathroom and under the shower. The demon's body scorched the Aziraphale's arms and chest, but he didn't care. He tried to freeze the water with a miracle but the heat was too much. He dashed out to the kitchen and yanked out the icemaker container along with a bag of peas and a frozen pizza. When he got back, Crowley was conscious but still immobile. Aziraphale dumped the ice and hit the switch for the fan to clear the thick steam out of the air. He crouched down next to Crowley and put the bag of peas under his head. The ice had already melted except for the cubes that had missed. Panicking, Aziraphale retrieved everything that was in the freezer and refrigerator. He turned the AC on as cold as it would go and searched the rooms for fans.
It was only a faint whisper but the angel heard Crowley call his name. He fled to the bathroom and knelt beside him. The demon feebly raised his arms out to him.
"Oh, I'm so sorry," Aziraphale cried as he hugged him. "I didn't think. I should have stayed. I'm sorry."
The shower wasn't very wide, but Aziraphale ignored the pain of the threshold cutting into his skin as he lay beside Crowley. Soggy wings at odd angles and frozen food containers piled everywhere made the scene look like some sort of modern art photograph.
The water rained down on them cold as ice but Aziraphale stayed warm with the touch of a demon. Crowley unconsciously fingered the angel's feathers.
"I love you," Crowley whispered.
