Alexander of Daventry walked down the rickety old wooden stairs after finding the proof he needed to show the kingdom that Abdul Alhazred was not only a member of the Black Cloak, but had murdered the king and queen. Just as he was about to press the button to exit the  disheveled and neglected secret passage, Alexander  heard the sound of voices coming from nearby.
Looking about, the dark haired human spied the chink in the old castle wall he'd used earlier to learn one of the black magic words he needed in order to open the treasury door. Not wanting to pass up the opportunity to learn as much as he could about what was going on in the castle, Alexander slipped down to one knee and peered through the chink in the wall only to be greated by a sight he was not expecting. 
One of the guards, the Captain of the Guards to be precise, was standing in front of what appeared to be a fireplace with another guard. No. That wasn't another guard. While the Collie Captain was in his green tunic and cuirass, the other canine Saladin was kissing while holding in his arms was dressed more akin to Jollo, the Court Clown, but his vest and baggy pants were less garish in color.
"He's kissing another man," Alexander whispered in curiosity, eyes glued to the scene in front of him.

"We are going to make this quick," the rough collie growled after breaking the kiss, leather gauntletted hands giving the slender sight hound's flank a good, firm squeeze. "The wedding will begin soon."
The sand and gray furred Afghan smirked back, hands moving instinctively to rub at Saladin's chest, even though a metal plate and tunic were in the way. "Paw, muzzle, or
do you think you will be able to keep from knotting my ass?"
The blood orange, black, and white dog huffed, giving the other dog's rump another firm grope. "You already know what I desire, Khalil."
"Then you best not tie me if you do not want to be late," Khalil smirked, keeping one hand on Saladin's chest while the other paw traced down the collie's cuirass, over his sword belt and chain mail loin protection only to slip under his tunic. The Captain reacted just as the hound knew he would, letting out a deep, heavy groan as his sheath was caressed and squeezed.
"We do not have time for teasing," the guard snorted, only for his lover to pull away, a lusty smirk along his muzzle.
Turning around, Khalil reached down to his hips and shoved his baggy pants down to his knees, exposing his fluffy, femenine flank before moving onto all fours, slender tail hiked high into the air.
The collie licked his lips at the sight before striding over to his lover just to slip down onto his knees. A gloved hand reached out to grab the hound by the hip as its twin pulled up his tunic and fish out his own thick, knotted length. Snorting, Saladin guided the tapered, pre gushing tip up towards Khalil's winking puckered entrance, spreading some of that natural lubricant about the inviting ring only to give the Afghan a firm thrust.
The slender hound let out a hot and heavy moan, eyes shutting tight and jaws opening wide only for a gauntletted hand to reach out and shut his muzzle. "We cannot be discovered," Saladin growled in a dominating tone while that girthy shaft spread Khalil open, inch after meaty inch pushing its way into his body. The other dog whined
and whimpered as he nodded his head slightly, feeling strong hands gripping his hip and long muzzle tightly.
The collie growled, eyes closing as he pushed himself further and further into those warm, tight confines until his lover's ring smooched the bulbous mass at the base of the Captain's length. "I love you, Khalil," the muscular herding dog groaned as low as he could before he began to thrust, hips moving in rapid motions.
The Afghan whined louder, his moans stifled by that iron grip keeping his maw shut. Even though he couldn't vocalize his pleasure, the hound's body was doing it for him. His puckered entrance groped and squeezed along every inch of meaty collie cock even as it jabbed at his prostate.
Saladin kept every thrust hard and fast, forgoing depth for speed and the need to fill his lover full of seed. Those somewhat droopy ears folded back, the rough collie growling louder as his hips clapped off the sight hound's girly flank. Lips began to curl upwards, fangs glinting in the firelight. His grip seemed to get tighter and tighter only for the Captain of the Guard to shove his hips forwards, exposed fur rippling as he bent towards his lover's back. 
"OOO-AAaaaahhh!" Saladin groaned, nostrils flaring as he finally let go of Khalil's muzzle.
"S-Saladin," the hound huffed heavily, chest heaving up and down as he looked over his shoulder.
Snorting, the collie slowly dragged his now free hand down the curve of the Afghan's spine only to grip his hip just to push him forwards. Both dogs let out long groans as Saladin's member slipped out of Khalil's rear entrance. 
"I must attend to my duties," the loyal Captain of the Guard panted as he stood up, tunic and chain mail loin protection moving to rest on his quickly retreating member.
"I know," the slender dog replied, staying on paws and knees as he looked back at his lover. "We will have all night to celebrate after Princess Cassima's wedding," Saladin grinned.
"I look forward to it," Khalil winked back before his lover departed the chamber.

Alexander blinked, his mind processing what he'd just witnessed. Information like this would be useful should he ever run into the Saladin again, but blackmail just wasn't Alexander's style. Besides, he already had the proof against Alhazred he needed to show the loyal guard dog if or when that situation arose.
