a/n: happy (late) birthday faith! I wrote this special for our favorite rainbow unicorn! Lol.

"No way, Snape! There is no way that you are better at sex than me! I am a sex god!" proclaimed a teenaged Sirius Black to a young Severus Snape in an empty classroom one day.

The Slytherin scoffed. "I am a Slytherin! I am way better than you!" Snape said calmly.

"Prove it.' Said the Gryffindor.

"How?" the boy asked. "Am I just supposed to bend you over a desk and fuck you right here, in an abandoned classroom?"

The other boy just smirked a smirk that put all Sytherins to shame.

"Anybody could walk in and we would both get detention, probably with Slughorn. Do you realize how awful that would be?" Severus said, making excuses.

"What, are you scared?" Sirius taunted.

At that the Slytherin strutted forward and kissed his best friend (Regulus Black)'s brother firmly on the lips. He swiftly darted out his tongue to lick at Sirius's bottom lip, asking access to the other boy's mouth. He quickly allowed access and they both moaned.

Severus had Sirius backed against a wall with his arms pinned above his head. Severus quickly began taking off his school uniform, while Sirius did his best to help. Once Sirius was naked Severus gave a satisfied smirk and gazed at the shorter boy's magnificent body. Sirius had a burning intensity in his eyes that Severus had never seen in anybody ever before. At that moment Severus could truly see a pouncing lion standing before him.

Sirius then pulled off the Slytherin's clothes so that he wasn't the only one who was naked. They began passionately kissing yet again. Severus then turned Sirius around and bent him over Slughorn's desk. He forcefully, without warning, thrust into him. They both moaned loudly at the feeling of it, Sirius's moan was half pain, but he'd never tell. Severus pulled almost all the way out, but thrust back in quickly, earning a moan from Sirius.

At that moment, Slughorn walked in to get a few papers off of his desk and had a mental breakdown over it. The boys noticed, but finished fucking before they sent him off to St. Mungo's where he stayed until shortly before Harry Potter's seventh year. He still had painful flashbacks every time he walked into his class, but managed to repress them. He was also never able to look at Severus Snape the same way ever again. Harry Potter never found out what happened that day, and hopefully never will.

The end.

I may have emotionally disturbed myself… Poor Slughorn. Reviews?
