As much as he was enjoying watching the pastor miserably slobber over a horse's cock, Ty was set on getting a bit more entertainment out of this pastor before his "deal" was done. The demon reached down to the pastor and gripped him tightly by the shoulder, yanking him up to his feet and out from beneath the stallion's belly. Ty brandished his face a few inches from the priest's, smirking cruelly. "Liked your taste of horsecock, Father? For your sake, I hope you lubed him up nicely." The pastor's eyes widened as he was shoved back down onto the altar, with his chest down and his ass raised. With a single swipe of his powerful hand, Ty ripped the pastor's robes from the waist down, followed by his briefs, until his ass was bare and quivering before the crowd of monsters and demons. The demon then turned to his stallion, and gave it a harsh slap on the haunches. "Go on, boy."
The stallion reared up again, placing two hooves on either side of the pastor's head and balancing above his body. His monstrous cock lay across the priest's back, drooling precum over his shoulders, before the demonic horse drew his hips back, angling the flared head of his shaft to the man's entrance. With a whinny, the stallion drove forward, forcing the pastor's asshole to stretch to fit his blunt tip. After a second or two of struggling, the man howled in pain as his entrance stretched wide enough, and the hellish stallion's cock drove nearly a foot into his asshole.
True to his blood, the demonic horse took no care for the pastor's health. He began thrusting and pounding away with all the power in his muscular hips and legs, forcing his huge cock deeper into the man beneath him. The pastor himself shuddered in near agony with every thrust. He bent over the altar completely, closed his eyes, and pressed his hands together in prayer. As the stallion grew rougher, he began to pray out loud, crying, "please, my Lord, spare me in this hour of need! Please!"
In the midst of all the thrusting, Ty got a decent look at the pastor's cock. It was completely flaccid, bouncing weakly between his thighs whenever the stallion's heavy, leathery balls slapped against his own small hairy pair. "Not enjoying yourself?" Ty taunted, leaning over to murmur in the pastor's ear. "Tell you what. You keep praying, and I'll do my own thing, and we'll see who...finishes...first, hm?"
Without any more hesitation, Ty dropped to his knees and leaned forward. He took the pastor's flaccid cock entirely into his mouth and throat, gurgling and teasing the length of it. He was determined for this pastor to cum while a horsecock slammed into his ass, to prove he was fully out of God's reach. To his satisfaction, it wasn't long before the pastor's cock hardened in his throat. The priest began praying louder, clearly growing distressed with his arousal.
Ty simply rested still. The demonic stallion thrusted roughly into the man's ass. In turn, the human's hips thrusted forward, driving his cock deeper into Ty's throat. Knowing it wouldn't be long with so much stimulation, Ty began to bob his head. When he began to feel the pastor's cock throbbing in his throat, knowing that he was mere seconds away from orgasm, Ty pulled off and stood up, leaving the pastor without any kind of sensation on his cock at all. "You know you're about to cum from nothing but a demon's horsecock in your ass, right?" Ty teased, chuckling to himself. The demon leaned over and gave the stallion's rear another slap. "Harder, boy."
In a couple more powerful thrusts, the stallion drove his entire massive shaft into the pastor's asshole and stayed embedded there, pumping an immeasurable amount of cum straight into the human's colon. The priest broke down as he reached his own climax, crying out as his cock pumped a several spurts of cum onto his beloved altar.
Ty sat back and watched as the priest coughed and shuddered, and the stallion above him remained buried balls-deep in his ass. When the demonic stallion finally pulled out and clopped several steps away, the pastor's legs gave out and he crumbled to lay on the stone floor. Ty stood over him, smirking. "Well, a deal's a deal. You're free...though, I suppose, nobody ever warned you about making a deal with a devil."
