Draco has a filthy mouth. But so does Potter.
"Just what the fuck Malfoy? I am so sick and tired of that mouth of yours", gritted Harry through his teeth, where he had him pinned against the wall with his arm across his throat.
A look of pure hatred on his face. He was going to enjoy splitting those lips open, watching as the blood came pouring out once he punched him in the fucking face.
"Fuck you Potter - you're just jealous that I know more words than you do, you prick", sneered Malfoy at him, trying to get away.
"I don't doubt that - pretty little snob of a boy aren't you?", bit Harry.
"Aw Potter, you think I'm pretty - always knew you were a faggot".
"See, this is what I'm talking about. That fucking mouth always getting you into trouble", said Harry clicking his tongue.
"I'm not in any trouble Potter - you're the one who's overstepping personal space".
"And you're the one who never fucking shuts up Malfoy - always having a go at everyone -it's quite pathetic".
"Not as pathetic as your hair Potter".
Harry pursed his lips and tightened his grip across the pale throat.
"How about we make you look pathetic as well Malfoy", and he grabbed him by the hair, and shoved him to his knees.
Draco looked up at the hero through his eyelashes, a flicker of fear crossing his features.
"What are you doing?", he asked, his throat dry from being manhandled.
"Why, I'm going to put your mouth to better use Malfoy. Can't have you spewing nonsense and not pay for it, now can we", smirked Harry and opened the zipper on his jeans with a snap of his fingers.
Draco realized what he was doing - and tried to get back to his feet.
Harry tugged on his hair, keeping him in place.
"No! You have misbehaved Malfoy and this is your punishment. You are going to put your money where your mouth is Malfoy - around my cock", demanded the hero.
"Fuck you Potter", he said again.
"Oh no, that comes later pretty boy - now it's just you sucking me off for the way you talk to people", said Harry and pulled Draco forward by the hair making him wince.
Harry was already rock hard seeing the Slytherin on his knees in front of him - and oh god - it gave him a rush of power. To see this perfect specimen groveling on his knees, knowing that he would beg for his cock and for his own release.
But Harry was a bastard in the same way that Malfoy was a self centered arsehole.
Draco knew there was no way out of this, and so slowly he opened his mouth, allowing Harry to feel the warm wetness inside. The heaviness of his prick resting on that pretty pink tongue had both boys moaning.
"Now you kneel and stay still - I am going to fuck that gorgeous throat of yours - and don't even think about stopping until you swallow all of me".
Draco wrapped a hand around the base of Harry's cock which was quite a healthy size, and closed his lips around the head. His mouth full of spit, he coated the shaft and started gliding his head up and down, using his tongue like an expert.
Twisting his hand up at the head to make up for the space that his mouth couldn't reach, he soon started a rhythm that had Harry bucking into his mouth making him gag.
"That's right Malfoy - this is the only way to keep you quiet isn't it? The only way that you listen to reason. If your mouth is full of cock, then you can't talk shit can you?"
