Soren and Steam kissed over his back, tongues tangling, battling less than playfully between their muzzles as if they were feral stallions fighting for dominance. Only that was far less fun than what they were doing, double teaming and double fucking their father, one at each end, spit roasting him like the daddy slut he was. Soren grunted, pressing his brother back as he took control, taking what he wanted as he always did, the older twin, even if only by a few minutes. With things such as that, to him, it mattered.
Yet lust could not and should never have been held back, not in any way. They moaned, kissing deeply, though Steam could not help but soften, ever so slightly, into the kiss, shaking against his brother, needing it too. Oh, how desperately it was needed, that tingling ache and drive of pleasure, the pressure of it bearing in on his mind. His cock throbbed within his father's backside and, unconsciously, Steam sped up, eagerly flagging his tail as he pounded into his father with raw, wild abandon.
There was no sense in holding back, not as the twins became one, losing control, letting themselves be who they truly were. If they were together then they would be so with their father, humping and grinding, pounding into his mouth and backside ruthlessly, giving the older slut all that he needed. Under him, Yvek grunted and shuddered and creamed his wasted load onto the bed sheets that he would end up cleaning later while the twins lounged around, ever their servant when they came home for the weekend.
But they didn't care and their father was right where he wanted to be too as they pounded into him, driving in harder and faster, Soren's hand gripping Steam's as the stallion squealed and broke the kiss. That would have set Steam off if he had not been so close already, but Soren was first, breaking free before him to spend his seed, thrust after claiming thrust, down his father's throat. There was nothing quite like those succulent, velvety lips to suck a stallion dry, after all, his tail flagged proudly as if in conquest of the older stallion that he had so defiled.
Steam grunted and tucked his chin down, belting out a neigh as his father clenched around him, losing control too and joining his twin brother in filling his father with thick ropes of stallion ream, spurt after spurt driving right up where it was needed. A heady, wanton slut like their dad, after all, should never be without a good load of cum filling them up and that was something very much that his sons were happy to provide Yvek with.
As he was filled from both ends, Yvek sighed happily, tucking his tail up and to the side, also that his son didn't have to brush or even yank it out off the way to get at his tail hole. Right there, he was happy, claimed in the submissive between his sons, settled there, lusting and longing for it. There, he was safe. There, he was protected. There, he could every last one of his kinky, perverted desires satisfied, over and over again.
All in the servitude to his twin sons, who did so love dominating daddy.
