Remus doesn't have energy to shower Sirius helps (slight nsfw)
Remus and Sirius were laying in bed after lazy sex. Remus had been having a really low energy and high pain day but a very horny day. This was frustrating for him because he truly wanted to be wrecked by his boyfriend. He wanted the kind of sex you felt for days but he also didn't think his body could take feeling anything on top of feeling pain and fatigue for days. So Sirius always the best boyfriend slowly brought him the pleasure he needed without hurting his body more. It was perfect.
But now Remus was so tired and he hadn't showered in a few days and he just had sex. So a baby wipe bath it was. He started pulling them out of the bed side drawer when Sirius said "what are you doing moons?"
"I'm dirty and tired so baby wipe bath." He gives Sirius a look that says I have done this so many times why the fuck are you questioning me right now
Sirius, unaffected by this look, gets up and starts helping Remus out of bed. "Baby I really can't get the energy to shower right now. Its just to much I think I might pass out if I try" he says calmly just explaining his level of fatigue.
This doesn't stop Sirius. He keeps walking them both into the bathroom towards the shower. Remus starts getting frustrated. Usually Sirius is so good about listening to Remus when it comes to his limitations but maybe he has reached his limit. Maybe he thinks Remus needs to just try harder and he doesn't want to be around a none showered partner right now.
"Sirius I really can't shower my body doesnt have the energy for all that movement right now"
"Then why are you leading me to the shower! I truly don't have the energy to... oh" he stoped his complaining when Sirius sat him down in the tub and sat himself outside of it.
Turning on the water to the temperature Remus likes while keeping him out of the water till it warmed up Sirius says "I now moons thats why you don't have to do any of the work. Now let me help you and calm down."
Sirius started with Remus' hair grabbing the shampoo and massaging it in. He spends longer then he needs because Sirius is obsessed with his boyfriends curls. How could he resist playing with them especially when it makes Remus' shoulders relax.
Once Sirius was ready to move on from shampoo he grabbed their shower head, they bought a detachable one for this and... other reasons but mostly this. It had been a light argument between the two of them, Remus being stubborn and not wanting their house or life to be different because of his disability, and Sirius wanting to make Remus' life easier and happier. One day Remus came home from work and the detachable shower head was there.
He was reluctant at first but then one day, a really bad one, Sirius lead him to the shower just like this and helped clean him in the softest, kindest, most loving way imaginable. Remus cried.
In the end the detachable shower head was perfect for them. Sirius lightly pushed Remus' head back and rinsed his hair. After that he grabbed the conditioner and made sure to run it through so every beautiful curl would be soft when it dried. He let the conditioner set and moved on to his boyfriends body.
"Can you turn to face me moony?" This is when Remus gets shy. Yes his boyfriend has literally been inside him more times then he can count and has seen every inch of his skin. This is different. This isn't lustful its kind and caring and such a different type of seeing. Remus loved and hated this kind of seeing.
"Moony baby you are beautiful. I can't believe life has given me such an ethereal boyfriend. I swoon every single day!." Sirius ever the dramatic always knows what to say to get his Remus out of his head. It is just sweet enough and just dramatic enough to remind Remus that even when Sirius truly sees all of him he will never shy away.
With that Sirius grabs a wash cloth, puts soap onto it and starts with Remus arms. He scrubs softly knowing his sensory perception is higher right now, being in a flair and just having sex will do that to you. He didnt want to overwhelm him.
He moves to Remus chest and stomach. As he reaches the lower part "is this okay?" Remus nods his head. At first this felt weird he had never had someone touch his private bits without the desire of pleasure. This was just careing. The first time Sirius helped him Remus refused to let him clean this part of him and said he could do it. One day he was so blissed out he didn't think anything of it when Sirius asked "do you want to or me?" And remus said "you, please"
Since then Remus has let him and it has felt less and less awkward but Sirius always checked in before proceeding. He never wanted to do something his boyfriend didn't feel okay with and these moments were supposed to be soft and loving so he wouldn't do anything to jeopardize that. His boyfriend deserved the world.
Then he moved onto his legs. "Are you able to stand for just a sec moons?" Remus didn't want to break the soft fuzzy feeling he was in so he just nodded and stood up. He could stand he just didnt have the energy to do all the complex movements of cleaning his body. Sirius cleaned the back of his legs and again when got to the top he asked "is this okay?" Of course Remus nodded again.
"Okay Remus baby sit down facing away from me." He did and cleaned his back. Then he detaches the shower head again and rinses rhe conditioner out of his hair.
"Can you turn around one last time my love" remus did as he was asked. Sirius grabs face wash and softly cleans his boyfriends face making sure to keep any soap out of his eyes.
Sirius turns off the water and helps Remus stand up wrapping him in a towel. He leads Remus back to their bed and lays him on his back. Grabbing lotion he starts softly applying it all over his boyfriends skin. Then he grabs the pain revealing one and massages it into the parts of his body he knows is hurting him the most. Staying in the places he notices Remus melt into his touch for a longer time.
As Sirius is massaging Remus he feels some of the pain lift away. The comforting touch of his partner soothing the agony he is experiencing. He feels himself become softer and is suprised he is still awake.
Sirius has Remus flip over so he can put lotion on the back side of him. Again ever so gently and making sure to take care of the extra painful spots with pain revealing lotion and massaging. When he is done he helps Remus flip over and cuddle into blankets.
"I am going to shower really quick baby are you okay staying here by yourself?" Sirius wants to be clean so he can comfortably cuddle but he also doesn't want to leave Remus alone.
"Can you leave the door open?"
"Of course moons" with that he kisses his boyfriends forehead and walks to the bathroom making sure to keep the door open so Remus knows he's still here.
When Sirius is done he puts on his softest clothes and cuddles up to Remus. "I love you moony baby"
"I love you Siri... thank you...for all of this, you really didn't..."
Sirius cut him off "I know I didnt have to but I wanted to. Seeing you happy and comfortable makes me happy. I love pampering you." They both drift asleep in loving bliss
