Sirius knows it's wrong. The lust and love he feels. It isn't right. Merlin! Harry is his godson, if that isn't enough reason not to feel how he does then what is.
Which brings him to his current situation. Here in the bathroom of Grimmauld after spending two and a half hours through a large meal with everyone with an aching hard on.
It was Harry's fault, the way he was eating that meal should be illegal. And the fact he kept accidentally brushing his legs against Sirius' just drove the man to insane. The way his tongue licked the cream off the strawberry delicately.
So now in the bathroom, where he had managed to escape, he was bringing himself to the state of oblivion imagining Harry's lips wrapped around his cock, bobbing up and down, with his teeth gently grazing along his member. He moaned loudly.
Just then there was a knock at the door, "Siri, are you ok in there?"
Panicking as he tried to come up with excuse and realising he had nothing he croaked out a "yes".
"Are you sure, because you sound like your moaning?" Harry smirked inwardly.
"Well, I have a minor problem, but don't worry I can take care of it." Sirius called through the door, hoping it was enough to get Harry to leave so he could finish his business.
"I don't think you can, I think I may have to come and help you, Paddy."
Sirius moaned at the double meaning and just remained silent.
"Padfoot? Can I come in then?" Harry asked him, and without waiting for an answer he walked in. What Harry saw was a sight to behold.
He smirked at Sirius, "well I have to say, I have seen smaller problems."
Sirius just stood there staring at Harry, he was unsure what to make of the situation, Harry couldn't possibly see him in that way. He then remembered the conversation he had with Remus earlier that day, he had told him his problem, he just smirked secretly as if he knew something.
Harry stared at Sirius's cock for quite a while before Sirius could say anything, he then managed to splutter a sentence of sorts, "Em.. Bl- Harry, what are you.. eh what are you in here.. I mean-"
"Oh don't worry, Siri, I know what you mean and I don't care, see I like you, Sirius, I like you a lot, and I know for a fact you like me too, you should really use better silencing charms, those were just to easy to break down"
"Harry, do you really know what you're saying, I mean, I'm your godfather, you can't really like me like that, can you?" Harry detected hope at the end of Sirius words. He would give his godfather exactly what he wanted. No doubt about that. "Siri, I really do like you a lot," and then he pulled Sirius in for a kiss. Sirius froze for a moment, but then gave in and melted in Harry's kiss. Lips moved together in perfect syncronisation, then Harry deepened the kiss, and when Sirius felt Harry's tongue in his mouth he melted. Harry explored Sirius's mouth eagerly and then allowed Sirius to do the same to him. They pulled apart and Sirius leaned his forehead on Harry's while they both attempted to breathe again, "are you sure?" He asked wanting more than anything for him to be. Harry nodded his head and Sirius lead Harry to his bedroom. He pinned Harry against the door and pulled him into a deep and passionate kiss. "Fuck me, Sirius" Harry demanded when the broke apart. Sirius shook his head slowly, "No." At Harry's dejected look he continued, "I'm not going to fuck you Har, I'm going to make hot, steamy, passionate ilove/i to you, so you know how much you mean to me." Harry smiled a broad smile at that and tossed Sirius unceremoniously on to the bed.
