As Buck looked down at Ty's impressive member, a thought came over him "c-could you maybe take me like a females?"
He looks away and blushes "it just felt soo good when you touched mine, I want to see how it feels when I take yours..."
Ty looks on in a moment of shock before exclaiming his own curiosity of what fucking a buck would be like.
He starts to move around, but he noticed that a member built for a draft animal is a little unwieldy on his current body, making him stumble a bit.
trying to look a bit more dignified for Buck, Ty said "I wish I had A body and cock more useful for fucking Buck"
With that, Ty's body began to grow and grow, becoming much burlier and hairyier. His jaw chiseling out to a nice square before a wave of thick facial hair covered it, filling out to a full beard. For some reason, the cloths next to Ty also changed, becoming a set of hunter's Camouflage. For A moment Buck was scared, and thought of running away, something about the new form just screamed "hunter" to him, but he kept his hooves firm for his new friend, and something a little more erotic biddedhim to stay as well. Ty continued to grow until he was a good six and a half feet tall of manly outdoorsman beef, before the change to his genitals began. His big sheath receded back into a human like foreskin as it enveloped a now human member, shrinking a bit to 14 inches, but it retained all of its stallion girth, being about twitch around the width of Bucks own. A mass of dense pubic hair surrounded its base and lead up to a definite happy trail that became a mass of hair on his chest. Ty's Balls only shrunk marginally, more condensing the heft of the horse nuts than anything else.
Ty let out a deep billowing chuckle, surprised, but happy with this more orthodox form. He scratched his beard and asked "what do you think Buck? You ready for a lesson in hunting?" Buck just looked on enraptured, even drooling a little from the hunk in front of him, making him feel a way a doe never could. After taking a moment to process, Buck said "hunting?" "It was a turn of phrase, er, ill tell you about that later."
Ty strode behind Buck and placed one meaty hand on his flank, and then another. Something about the steady touch made Buck raise his tail instinctually. Ty smiled down at the puckered hole, and made a few preliminary changes to make things go more smoothly. First of course, He made Buck completely clean down there, second, he made it self lubricating and modestly pliable, and third, he placed a few additional pleasure centers around the sphincter and made the cervine's prostate extra sensitive.
With that, he placed his fat tip at Buck's entrance, and started to grind. Up and down between the muscular flanks that supported a grand king of the forest like this, a steady stream of lubricant coating his member as whatever impromptu sex organ reacted to Ty's loving massage.
On Buck's side of things, he was experiencing something entirely new, a wave of heat and longing overflowed him. His longer cock leaping up against his sternum, plastering it with a few splotches of pre. He looked back pleadingly at Ty with biggest doe eyes.
Ty gave the Stag a wink, wrapped his brawny arms around Buck's haunches and brought his fat cock to swoop down and under, lifting Bucks own nuts and press against his feral cock. Buck felt the rythmatic beating of Ty's heart through his penis as it pressed against his own, and they just stood there for a moment, basking in each other’s warmth. Buck swiveled back and licked Ty's thick beard in affection and as a signal to go ahead.
Ty leaned back and began in earnest, testing out messaging in just the tip against the puckered flesh. With a little force, it popped in without much issue. Ty went slowly at first, but little by little, both parties were getting into it. hot condensed breath filled the forest air, and a plethora of new sensations bombarded Buck, his dick straining without even a hint of stimulation as his ass was reamed. And He was not just a passive participants either, after a bit, Buck actively pushed back into Ty's thrust, engrossed by the feeling of fullness in his ass and the ripples of pleasure it sent up his spine. Ty likewise was focused on the tight passage that perfectly conformed to his now jacked body, his thick man meat being squeezed and massaged in all the right ways. His fat nuts slapping lightly against Bucks own as excess lubricant dribbled down to the two sets of orbs to give them a proper wet slapping sound. With one mighty huff Ty strained his muscles and lifted the uplifted stud's hindquarters so that he could ram in for one final deep thrust. The sudden movement causing Buck to squeeze down hard in surprise, sending both men into the throws of orgasm. Buck let out a wild brey and Ty let out a trembling cry that would rival Conan. Gush after gush of thick human cum was pumped into the tender backside of the Stag as he himself painted the forest floor white for a second time. But it was no regular orgasm, Buck's legs shock erratically and he just kept cummings as his poor prostate was beaten over and over again with Ty's steady pulsating.
In the end, Buck stopped trying to keep himself up, and just let himself fall down on his chest, panting and huffing. looking back at the man who did this too him in flushed wonder.
Ty too felt even his large muscles trembling and getting sore, lifting however many pounds the hind side of a Stag weighs. His broad chest going up and down with deep breaths. "That was amazing Ty, I never felt anything like that."
Ty gently brought Buck's flank down to the ground and gave the at least bicurious stag a smile. "Well, why dont you come home with me. I can change it so that everyone thinks me being like this and having a stag friend with benefits is normal, or at least something not to freak out about."
Buck wagged his tail at the suggestion of staying with Ty and heartily agreed. He strode over to Bucks head, gave him a gentle kiss, and presented his goo covered member. Buck gave it a few tentative sniffs and was delighted by its masculine and oddly appetizing earthy smell. He licked it and was surprised with how great it tasted. It was like a salt lick. And Buck spent no time at all cleaning it all up and reveling in the process of polishing the musky man meat to a mirror shine.
"Is there any more changes you want before we head home and I Introduce you to the family?"
Ty also had a few ideas of what to do too if he felt like it.
