Harry Potter had experienced many things in the twenty-five years he'd been alive, he'd lost his parents as a baby, he'd come face to face with their murderer throughout six of his seven years at Hogwarts. During the year he didn't run into Voldemort he'd been chased through the forbidden forest by his werewolf professor and caught a rat Animagus that had faked its death which had resulted in his godfather been wrongly imprisoned for twelve years. He'd fought in a war and hunted Horcruxes, he'd almost lost his godfather again in the Department of Mysteries but a shield spell cast by Remus had saved his godfathers life, a debt Sirius had repaid when he'd saved Remus and his wife Tonks during the Final Battle.
Five years post war and he was married to the love of his life and was making his way up the ranks of the Auror Department. You'd think that in the now peaceful climate he wouldn't experience any more horrors. You'd also think that he'd have realised that something was going on between his Godfather and his best friend, but he hadn't, not until he was staring right at them as he stood inside Sirius's fireplace his mouth open wide in shock as his godfather repeatedly slammed himself into the curly haired witch his family's house words tattooed onto his pale arse.
"Oh, Kitten you are so tight," his godfather moaned as Hermione repeatedly chanted his name; "Sirius, Sirius, Sirius,"
"What the fuck," Harry spoke staring at the scene in horror, Sirius stilled, turning his head towards the fireplace while Hermione's closed eyes flew wide, her hands scrambling to cover her exposed breasts.
"Harry," she gasped as Sirius grabbed his discarded shirt from nearby and threw it at the girl to try and preserve her modesty. Hearing Hermione say his name while so exposed finally kicked his brain into action and Harry slammed his eyes closed, bringing his hand up to cover them in case his eyelids weren't effective at covering the scene before him.
"Harry you can open your eyes," Hermione told him a short time later, tentatively he peaked at them to ensure that they were decent before pulling his hands away and opening his eyes fully. Sirius wore a pare of grey jogging bottoms, his tattooed chest exposed while Hermione was dressed in a black t shirt that fell to her knees, though not dressed properly Harry was glad he could no longer see any of their private parts. Unfortunately for Harry though the pair still looked thoroughly shagged with tousled hair, sweaty skin and love bites on their exposed body, Harry shuddered and looked down at his feet.
"Harry I'm sorry you've found out about us like this," Sirius spoke quietly, Harry raised his head so that he could look into the grey eyes of his godfather, his mind trying to make sense of his words.
"How long," he asked unable to finish the sentence, how long had his best friend and godfather been shagging one another.
"Since the memorial of the Battle of Hogwarts," Hermione whispered.
"Five months, you've been shagging for five months," he accused them.
"The first time was an accident we were both drunk and one thing led to another but then it happened again, its serious Harry," Sirius told him quietly as he wrapped his arms around Hermione.
"We love each other," she told him, her eyes never leaving Sirius, so full of love and adoration for the older man that Harry felt all the anger leave his body. How could he be angry that two of the people he loved most in the world had found love, happiness what he and Ginny had with one another.
"I'm happy for you both," he told them smiling at the pair.
"Oh, Harry I was so worried you'd hate us," Hermione whispered hurrying forward to hug him.
"You're my sister Hermione I could never hate you," he told her as he returned her hug.
"Why did you come over, is everything alright," Sirius asked him, Harry couldn't help but beam; "Ginny's Pregnant," he told them happily, Hermione squealed and hugged him again while Sirius patted him on the back in congratulations and summoned a bottle of Firewhiskey.
Their relationship may be unexpected but that night as he lay in bed, his hand resting on Ginny's tiny bump, he couldn't help thinking that they were perfect for one another. They were opposites in many ways; old, young, male, female, pureblood, Muggleborn yet he could see how they worked. Both were incredibly smart, Sirius could keep up with and challenge Hermione intellectually, he could bring out the fun side in her and encourage her to break rules, to try new things. Hermione was kind and loving and could give Sirius the attention and love he'd craved for years; she could encourage him to reshape the House of Black into something to be proud of.
"I can't believe you didn't realise they were dating, they've been sneaking around together for months," Ginny whispered her voice full of amusement.
"Of course, you knew" he whispered leaning down to kiss her.
"I know everything," you wouldn't believe who Ron's dating," she giggled.
"I don't want any more surprises today thank you" he told her as he claimed her lips with his, Ginny moaning as he ran his tongue against hers.
