Jake closed his eyes and started grunting in time with Sparky's thrusts. He could feel himself getting close. His 13-inch dick bobbed in the air, left completely and totally ignored. Jake didn't care. He was getting exactly what his body needed most right now. The only way this could... get... better... if... he... had... more... dog...
"What the actual fuck?!" a deep voice shouted. Jake opened his eyes and locked onto the tall, imposing form of Coach Erinson. A tight shirt clung to his thick, powerful chest, and his shorts were just as tight against his meaty thighs. Jake's eyes latched onto the bulge in Erinson's crotch. If only Coach was like him!
"Coach!" Jake gasped as he felt Sparky's rod suddenly thicken inside him. "Transform or Dare! AAHH FUCK!" Sparky's knot swelled up and unleashed hot, gushing cum inside Jake's pussy. Jake couldn't hold back anymore, and his pussy quaked with a powerful orgasm. His dick started shooting right onto the floor. Sparky growled and howled softly but primally. Jake moaned lustily with each pulse of cum that shot out of Sparky's dick. His own dick seemed to shoot in sync with Sparky's. Jake gasped for breath as pleasure centered on his dick. He looked down and saw through the pleasured haze of his mind that his dick was darkening. It changed shape and tapered off to a slight point. His balls became a little fuzzy, as did the sheath that grew in around his dick. Jake wasn't entirely sure how he knew, but the smell of his cum changed from human to that of a dog. His dick pulsed with need, all ready to go again. He felt a new need inside of him. It was telling him that, now that he had been bred like a proper bitch, he needed to breed a proper bitch.
"Jake, I don't..." Coach Erinson stammered. Jake raised his eyes. His mind was lost to the pleasure. A part of him yelled at him to stop, to not do what he was about to do, but Jake ignored it. He needed to breed, and he needed more dick.
"Coach, it's been a minute," Jake said between panted breaths. "That means you get both. Your curse will be just like mine, except your changes will happen quickly and almost immediately, they can spread to others who touch your cum, and just like you, nobody will ever notice anything different about their bodies, even when they're getting fucked."
"Jake, I don't know what's come over you –" Coach Erinson began to say.
"Sparky did, but he came inside of me," Jake clarified. He leaned against Sparky and bit his lip. His doggy cock throbbed a little. Coach Erinson stopped talking as his eyes drifted towards Jake's crotch. "His big, thick, dog dick filled my pussy up in just the right way." Coach Erinson's crotch started to swell. Erinson licked his lips. "His strong dick painted my insides with his hot, wonderful doggy cum. He's knotted up inside me now. It feels so good inside my pussy, Coach."
Erinson grunted and took a step closer towards Jake. "Just imagine it: a big, thick dick filling up my pussy completely, fucking me, breeding me, giving me exactly what I needed."
"Mmph," Erinson grunted. He slowly dropped to his knees beside Jake. His eyes hadn't left Jake's throbbing cock. His shorts were tented obscenely. Jake could smell something in the air. Something needy, something desperate, something hot and bothered.
"I'm a good boy," Jake growled. "I took that hard dick with pride. Nothing feels as good, as right, as my mate's cock inside my pussy, as being his bitch."
"Bitch," Erinson growled in a much deeper voice than Jake ever heard. It added another thrill through him, even on top of the pleasure from Sparky's dick, which had somehow dulled to just a steady river instead of a rushing waterfall.
"That's right," Jake groaned. He palmed his cock. It felt different, but he wouldn't take his eyes off of Erinson. His Coach's hand slowly reached out and grazed the pulsing shaft. Jake groaned again and breathed directly into Erinson's face. Erinson's eyes dilated.
"I need it," he said softly.
"Need what?" Jake asked.
"I need... that... dick... inside me!" Erinson growled. His hands yanked down his shorts and spun around. His big, juicy, meaty ass was in Jake's face. But Jake could see the moist, quivering, and clearly ready bitch pussy staring back at him. He leaned in and began to lap at it with his tongue. He enjoyed the taste of his coach's juices, which began to flow more freely with each pass of Jake's tongue. Erinson growled more and leaned back.
"Fuck me... now, Jake!" he insisted.
Jake moved to try, but Sparky was still knotted up inside him. The tug made Jake shiver and nearly forget what he was trying to do in the first place. The coach's pheromones were definitely keeping Sparky raring to go. He wasn't going to release Jake any time soon, a fact which was further emphasized by a slight growl from the dog.
"You'll have to bring your pussy to me, if you want it so badly, Coach," Jake teased. Coach lowered himself even further to the floor of the locker room. He then slid backward, while Jake kept everything lined up.
His dog dick grazed the coach's entrance. Erinson whined and then slammed his ass against Jake's crotch hard. Jake's dick plunged into the warm, moist, and tight pussy. Erinson controlled the movement with his strong arms and legs. He thrust against Jake back and forth, back and forth, back and forth. He gasped, grunted, whined, groaned, and moaned with each plunge. The thrusts got stronger and stronger. Jake was rocking against Sparky's knot, sending further waves of pleasure through him. His pussy muscles clenched and kneaded the dick as his own pleasure began to rise again.
Finally, with a finally surge against him, Jake felt Erinson's pussy clamp tightly on his dick. The pleasure from the sensation surged through Jake's body and made his own pussy clench tightly. Sparky growled again as the cock erupted inside Jake. The overwhelming pleasure cascaded over him once again, and he felt his own dick knot up inside the coach. Warm hot cum burst out of his dick inside the coach, while his knot firmly kept it all in place. He rested his now sweaty head against Erinson's large back.
A tingling sensation centered on his mouth. His tongue started to get larger and larger. He opened his mouth and felt his tongue flop out. He panted a little and even found himself licking Erinson's back, making the larger man shiver. The three of them, Sparky, Jake, and Coach Erinson, lay on the floor of the locker room in silent, pleasurable bliss.
