Padfoot and his date snuck into the cottage in Godric's Hollow, stealthily creeping into the darkened family room. His good friends James and Lily were upstairs asleep, so this would have to be a quiet quickie.
His lady friend for the evening was a well bred little baggage with long, sleek legs that went on forever. He couldn't quite remember her name, Dolly or Prissy or some shite, yet she was panting after a hard rogering like a pooch begging for a bone. The sly old dog had been on the prowl when the poor girl practically latched onto him, throwing herself at him like a bitch in heat.
Moving further into the room, he growled as his date went down on all fours on the Potters priceless Persian rug, ass in the air just waiting to be bred. Moving to cover her shapely flanks, he licked at her sweltering pussy, practically tasting the overwhelming pheromones. He quickly thrust his aching cock into the tight slit, hilting himself and proceeding to deep dick the moaning, screaming piece beneath him. He had communicated the necessity for quiet, it wouldn't be his fault if the bint woke the whole neighborhood with her lusty howling. Hunching forward, he sharply bit into the juncture where shoulder met neck, effectively silencing her and asserting dominance.
As Sirius tied one off in the now satiated cunt, lights invaded the room.
"What the actual fuck, Sirius?" Lily demanded, hitting the coupling pair with a kitchen broom.
Padfoot whined, his knot stuck in the cowering bitch beneath him as he was repeatedly beat by his livid, disgusted friend while his other friend laughed uncontrollably, filming the scene with the new muggle device they had received as a wedding gift. The poor greyhound he had picked up was extremely confused, attempting to pull away from the thick dog knot splitting her battered slit open in order to escape the attacking two-leggeds.
"Sirius Orion Black, this was not the reason we installed the doggy door. I deliberately told you not to be bringing bitches home while you stay here, although I didn't figure for the four legged variety," Lily screeched shrilly, abandoning her broom and plopping herself on the divan to wait out Padfoot's knot. "You disgust me, Black. Taking advantage of a poor innocent animal like that. She doesn't know any better but you certainly do. Isn't she the Deskins' purebred prize winning race greyhound? Merlin, you better not have impregnated her. I don't know how we will face the Deskins. I will personally neuter you!"
Padfoot yelped, hiding his face under a paw. "Isn't that a little harsh, Lils," questioned James sheepishly. "It's the animal instinct, besides, don't knock it til you try it."
Lily slowly turned to face her husband and demanded, "Are you admitting that you mate with other deer when you go out as Prongs?"
"Erm- well you see… Lily no it's not like that! Don't pull your wand out! What happens in the forrest stays in the forrest… Ack no let me explain," James panted, running from his enraged wife for dear life.
A few months later a litter of half greyhound, half unknown, suspiciously intelligent and oversized puppies were advertised in the paper. Sirius ended up taking the entire 8 puppy litter. He went on to own a successful dog farm where he works as a stud.
Lily eventually forgave James for being a horny old stag.
