Sirius swaggered into the great hall, his magnificent hips swaying from side to side in an almost hypnotic manner. Sirius crawled on to the Slytherin dining table, all the way to Severus.
"Sirius!" Severus cried, "What are you doing?".
Sirius climbed onto an empty platter, "Baste me baby and I'll marinade your world!"
Severus's eye twitched and he paled.
"Wha…?" Severus floundered.
Sirius crawled onto Severus's lap and ran his hands through the Slytherin's tangled black hair.
"Oh Sevy!" Moaned Sirius, "It's time we stopped pretending."
Using the knife beside the roast beef, Sirus sliced open Severus's shirt, revealing a toned, uber-buff chest.
Sirius drooled while girls fanned themselves and sighed in appreciation. Sirius brushed the cool butter knife up and down his chest. Severus's nipples engorged and he tossed back and forth, writhing and moaning at the cruel sensation.
Sirius poured gravy over Severus's chest and then slowly began licking it off, biting on the Slytherin's stiff nipples and broad shoulders.
Severus was in sensory overload. He could feel himself responding to the Gryffindor's actions and he was sure Sirius noticed it too.
He used a very handy spell to remove Sirius's clothes revealing the Gyffindor's bulging broomstick.
"Wow," crooned Severus along with the rest of the Great Hall. Sirius resumed his gravy pouring, emptying the jug over Severus's no longer covered knob. Severus groaned in pleasure.
Sirus lapped at the gravy-covered meat and engulfed it all with a single swallow.
Severus's eyes widened and his knuckles turned whiteas he tightly gripped his chair. Sirius moved so he was sitting on Severus's lap. He rubbed his hips eagerly against Severus, enjoying the sensations coursing through him.
All too soon it was over, and Sirius and Severus were covered in more than just gravy.
Severus gave a cough, "Well thanks for that." He said as he readjusted his tie.
"No problem." Sirius responded as he exited the Great Hall the same way he entered, on all fours.
Severus chuckled and shook his head, Sirius was such a dog.
