Harry had another tutoring session with Professor Lupin that night and he had some homework he wanted help with – a Defence essay about werewolves. Who better to help him with his homework on werewolves than a real werewolf? Harry took a blank piece of parchment, his quill and ink bottle. He didn't expect Professor Lupin to write it for him, but he could definitely help. Harry sat down and explained to his tutor about his latest essay – how to identify a werewolf and advancements which make them safer to be around humans. Remus looked at Harry's blank piece of parchment then looked at Harry "So, how do you identify a werewolf. What are the five main differences?"
Harry looked at him blankly. "Although I hate to bring this up, Harry you've seen a werewolf. What were the differences?" Remus asked.
Harry looked at Remus then said "I wasn't really paying attention to the differences between a wolf and a werewolf that night. I had other things on my mind." Remus looked at Harry, trying to read him, so Harry continued "If you wouldn't mind finding a wolf and transforming next to each other for the purpose of my essay that would be great." As soon as Harry looked up at his Professor, he knew he'd made a mistake. It looked like fire was burning behind his tutor's eyes. "Harry I am here because your godfather wants you to be able to protect yourself against Voldemort when he inevitably comes back. This" he gestured towards the blank piece of parchment Harry had, "is wasting my time. I think I should be going." Remus stood up and without even saying goodbye, left the Transfiguration classroom. Harry looked at the door in shock then kicked the chair next to his.
Meanwhile Remus was furious, it was close to the full moon and he was irritable to start with. Normally if a student was sassy, he would sass them back, but near the full moon, he just didn't have the patience. He left the castle and went down to Hogsmeade where he got the two-way mirror out of his pocket, telling Sirius he was going to the cave where he was staying. When he got there, Sirius could see that he was agitated, he asked what's wrong only to be hear the story of Harry sassing him. Sirius looked at Remus before saying "I'm sure he didn't mean it, Moony. He's a teenager." Remus was still furious. "It's ok, you're just irritable because it's close to that time of the month. Here, let me make things better for you. Sit down."
"Where? The floor is filthy." Snapped Remus. Sirius stepped back; Remus never minded about the dirty floor a week ago when they shagged on it. He thought for a bit before Sirius said, "Here, give me your wand and I'll apparate us back to yours. We can talk there." Remus handed over his wand, but as he motioned to hand it over, he said irritably "If we go back to mine, you're showering first, and I get to wash those clothes. I swear every time I see you, it's like Padfoot has been rolling in something horrible."
"Yes, well, Padfoot does like it dirty," muttered Sirius under his breath, before he apparated the two of them back to Remus' cottage.
Remus instantly stripped Sirius of his clothes then sent him to shower. "Aren't you going to kiss me first?" asked Sirius. "Shower" growled Remus in response. Sirius knew it was going to be one of those nights where the wolf dominated him. After showering himself under the hot water, he walked out to Remus' bedroom in only a towel. "Drop the towel" stated Remus from the bed. Sirius hesitated, so Remus repeated himself, so that Sirius complied. "Sirius, are you willing to do what I say?" Sirius nodded, then went over to Remus and started to kiss him. Remus pulled away then said, "I want to watch you play with yourself." Yep, thought Sirius, it's going to be one of those nights, but he did what Remus said and took his cock in his hand, giving it a little rub. After a short while, Remus grabbed his hand and growled "Now it's my turn." Sirius undid the button and fly on Remus' pants and started to stroke his shaft. "Suck it" demanded Remus. Sirius knew better than to make him wait when he was like this, so he started to lick it. It didn't take long until Sirius could feel Remus was ready to come. At which point Remus stopped him. "Get on the bed" Remus demanded. Sirius looked at him, then walked over to the bed and lay down. "Turn over" he said. There was no denying what the wolf wanted. Sirius rolled so that his face was in the pillow. He gave a small squeak as Remus entered him. After what felt like quite some time, but was probably only a minute or so, he could feel Remus come. Sirius turned around and cuddled Remus close while they caught their breath, before Sirius asked if it was his turn yet. Remus nodded then moved to give Sirius a blow job.
When they were both spent, they slept soundly until morning when Sirius woke to a tapping noise at the window. He looked over to see Hedwig sat on the window ledge. He went over to the window and opened it to let the bird inside. Hedwig sat at the end of the bed, refusing to give Sirius the letter, instead preferring to give the letter directly to Remus instead. When Remus finally woke up, he took the letter from Hedwig and read it:
Professor Lupin,
I'm sorry for being so rude towards you tonight during the lesson. I hope you will forgive me and that I can see you again very soon to practice some hexes and defence spells.
Harry
"What is it?" asked Sirius.
"He's apologised for last night" replied Remus.
"He's a good kid, our Harry," smiled Sirius, "Are you going to reply? Hedwig is waiting."
Remus nodded then slowly got up out of bed to find a quill to respond
I'll see you next week after the full moon.
Remus
Before attaching it to Hedwig's leg, and allowing Hedwig to fly out the window back to Hogwarts. Remus looked over at Sirius and said "You'd best be going. I don't want any aurors snooping around to find you here."
"Tonight is the full moon. I'll stay to keep you company. The aurors don't know about Padfoot. I can be your loveable stray until tonight."
Remus just looked at him, before Sirius added, "Plus, I don't have any clothes, you took them from me last night." Remus suddenly remembered that he had taken Sirius' dirty clothes from him the night before with the intention of washing them. He looked over at Sirius and said "Choose something from my cupboard. I'll wash your clothes soon." Sirius walked over to the cupboard to see two shirts, two cardigans and two pairs of pants "Why do all of your clothes look like teacher clothes?" he asked.
"Because they were teacher clothes. If you don't like them, order some new clothes via mail order. The Goblins at Gringotts are refusing to divulge any information about your account to the aurors. They told me that last time they came knocking asking about you," suggested Remus. Sirius thought about it, then decided against it. He didn't even know which stores were still in business. He went to follow Remus who had now moved to a basin to wash Sirius' dirty clothes. He noticed that Remus was having trouble kneeling down. "What's wrong, Moons?"
"Full moon tonight, Pads, just feeling a bit sore," he responded.
"Here, let me", Sirius said bending down.
"I'm sore not an invalid," protested Remus, "just takes a bit longer near the full moon is all."
Later that day, Sirius walked into Remus' bedroom to find him lay on the bed on his stomach– "just a bit sore" he complained. Sirius sat down next to him on the bed and started to massage his shoulders "I know what you need" he quipped as Remus gave a little sigh of relief. After a while of massaging his back, he rolled Remus over to his back and started working on the front. Before long, Sirius was undoing his lover's belt and taking his flaccid cock in his mouth while Remus gave little moans.
Remus was feeling better than he usually did before a full moon thanks to Padfoot's magic. When sunset came, they both went down to the cellar in his cottage and waited for the full moon to rise. As Sirius could see Remus turn, he became Padfoot and they settled in for the night. The wolf didn't feel much like sleeping, but in the early hours of the morning, he was finally convinced to lay down with his mate.
When Remus woke in the morning, Padfoot was lay on him as he stirred. When Padfoot could feel Remus move, giving his back little strokes, Padfoot became Sirius and grabbed Remus' wand. He charmed Remus to make him feather light, then carried him out of the cellar onto the bed. Once he was on the bed, Sirius got the first aid kit from the bathroom and started to give Remus a series of healing potions, as well as check him over for scratches and bites. There was a nasty gash on Remus' left thigh which was quite deep. Sirius placed a healing potion on the gash before taking Remus' wand and muttering some healing spells. It would still take some time to heal, but it he hoped it could at least stop bleeding soon. He wrapped a bandage around it before moving onto some of the smaller cuts. Once Sirius had finished with the first aid kit, he placed it on the bedside table, then gently dressed Remus in his plaid pyjamas, before the two of them slept cuddled up to one another.
Late in the afternoon, they awoke to Hedwig tapping at the window again. 'Blasted bird' thought Sirius as he ran to the window, trying to get the owl to stop before she woke Remus from his sleep, but it was too late. Hedwig sat at the end of the bed, like she was surveying the damage. Sirius quickly got back into bed. Hedwig stared at them together in bed, with a look on her face that Sirius couldn't figure out was good or bad. Remus eventually stirred and took the letter from her. She didn't leave. It seems Harry had asked her to wait for a response. The letter read:
Sorry, I forgot about the full moon last night. So when can I see you again?
Remus groaned. Then asked Sirius to search for a quill. Once he had a quill, he sat there on the bed, thinking out loud, sucking the end of the quill. "Stop sucking the quill, or I'll want you to suck something else soon," joked Sirius. Remus turned to Sirius and ignored what he had just said. He stated "Harry wants to see you soon. If Harry is free this weekend, do you want to see him? I should be able to get him to Hogsmeade."
"Of course," replied Sirius.
I will organise with the school to see you this weekend. I will bring my rescue dog with me. I will send you details later.
Remus turned to Sirius, put his hand on Sirius' leg and stated "You can't stay here much longer, Pads. It's too risky. The aurors know I'm likely to see you. Grab the things you need, then I'll apparate with you back to Hogsmeade." Sirius sighed. He wanted to stay with Remus for longer, but he knew Remus was right. "Just a little longer" Sirius offered as he cuddled into Remus.
