Jeff knew Duke could smell a bitch in heat as soon as they entered Dean's house, a direct nose to brain to cock link that had Jeff feeling a little frisky in the sheath.
Duke let out a couple of sharp barks, impatient as he danced about waiting for Dean to unhook his leash. Jeff too was excited, felt the he head poke through the furry sheath a few inches and took a moment to look around. He couldn't see much, most of his vision filled up by Dukes long hair. But it didn't matter, he was excited at the prospect of breeding up whatever bitch was ready and waiting.
Dean laughed, taking in Duke's excitement. "Never gets old, does it fella?"
Jeff could feel himself swinging in the sheath as Duke trotted forward further into the house and into the livingroom, where he paused next to a kennel containing the in heat female German Shepherd.
"Alright alright, I'll let you at her to make your introductions, just give me a minute" Dean intoned, making his was over to where Duke and the female Shepherd were trying to sniff each other through the kennel bars.
There was the sound of a metal latch unhooking and a short squeak as the kennel door opened, female Shepherd taking no time to come out and come over to investigate Duke, during a cursory sniff over the usual spots before Jeff suddenly found a hot tongue bathing over him, licking up the collection of smeg collected at his sheath.
He could feel the tiny pulses of Dukes hips at the contact, and felt his own excitement growing.
Duke must've been doing his own investigations, as in short order Jeff felt Duke move.
He still couldn't quite see what was going on, knew his cock head was poking out of the sheath again - felt a little more of an excited buzz coursing through him, as he felt himself reoriented - pointing up and forward, Jeff suddenly feeling himself being jostled a little more purposely as Duke's hips startled circling, as though in search of something.
It didn't take him long, and Jeff only managed a quick glimpse of the puffy triangle of the bitches vulva before he was abruptly making contact with the slick warmth. He could feel the way his cock head was catching on the folds, rabbiting in quick jabs before abruptly he sunk deep inside the wet warmth.
"There you go bud, caught her good" Dean commented, watching as Duke began pistoning his hips in renewed vigor.
Jeff was in bliss. The females snatch was hot and slick around his cock and he could feel himself rapidly lengthening as Duke fucked him in, in, in.
It felt so good Jeff felt like he could cry, and was aware the in a way he was as there was watery pre jetting from his mouth, soaking the bitches insides even more.
Jeff could feel the pressure, the need for release coming up on him fast and felt the base of his cock beginning to bloat obscenely, stretching the vaginal walls gripping him tight.
Simultaneously, Jeff realized the mad thrusting had stopped - subsiding to little rocking motions at the same moment that a huge shot of watery dog cum shot out of his mouth and deep into the females channel.
He could feel the way his knot pulsed and his cock kicked with each volley of virile cum he shot deep within the female.
Jeff knew he was knocking up this bitch, and the realization had Jeff groaning mentally as he continued to fire off huge loads of doggy cum.
Eventually, Duke's cum subsided and Jeff basked in the tight heat of the females snatch, enjoying the continued pleasure even as he felt himself twist around - they were butt to butt Jeff's human mind supplied, knowing that now it was just a matter of waiting out the tie -- ensure that none of Duke's previous puppy batter leaked out.
Jeff didn't know how it could, once it had been shot off deep into the female there had been no trace of it pooling back on Jeff's length. Knew that Duke had blown his load deep into the female's womb.
