While Rex's Rottweiler body meant he was a larger type of dog, Frank still had to observe everything from what seemed like floor level.
Rex used his now human hands to open the door, and admitted Xander, a young man with light brown skin, a slender but well-defined build and, although Frank's view of it had changed perspective, a perky bubble butt. He had his arms full of bags of produce and other dinner ingredients, but he leaned in for a quick kiss. Noticing Frank's uncustomary stiffness, Xander kidded him. "Is that any way to welcome the guy who is about to fix you the most fantastic dinner?"
"Don't make him suspicious!" Frank warned with a couple of intentional barks.
"I'm not trying to," Rex retorted to the Rottweiler.
"Trying to what, babe?" Xander asked as he walked into the kitchen to unload his groceries.
"Never mind," Rex said. He was still feeling strange from the kiss, which had stirred some unusual feelings.
Frank trotted into the kitchen, too, and caught Xander's attention. The young man extended his hand and patted his head. "How are you, Rexie?" Xander asked.
"He's fine," Rex said. "He's just a normal dog."
Xander laughed and gave his new boyfriend a weird smile. "And what about his owner?"
Frank kept gazing at Xander, somewhat dismayed to have to see his boyfriend in such a manner.
"His owner?" Rex said. "You mean how am I?"
"Yeah," Xander said. "You seem a bit odd. Has it been a long day?"
From reflex, definitely an involuntary reflex Frank told himself, he sniffed Xander's butt. He'd never known that Xander gave off such a strong scent. The musky smell made Frank feel light headed and slightly aroused.
"No. Normal day. Nothing unusual happened." Rex impressed himself with the ability to spin a quick network of lies, the truth being that it had been one of the most unusual days of his young life. He just hoped he was doing a good job playing human.
Xander leaned down in front of Frank, and scents from the young man's crotch region launched more feelings of arousal. Frank whimpered softly as he felt his dick stretch in its new fur-covered sheath. Xander patted the dog. "Wow, both my main guys seem out of sorts this evening," Xander said. "Wish there was something I could do."
Frank barked for Rex's benefit. "Get me away from him. Please."
Rex ducked around Xander and grabbed Frank by the collar. "I guess he's a bit too excited," Rex said. "Guess that means he likes you."
Although his senses were considerably diminished in his human form, Rex detected some tell-tale signs that told him that his master, now in Rex's former canine form, was quite aroused. He excused himself to take the dog into the yard.
"No problem," Xander said. "I'll start work on dinner."
Once outside in the yard and the door shut behind them, Rex questioned his former master. "Xander's a male," he observed.
"So?" Frank barked defensively.
"He isn't female, master, but you seem to be..."
"Whoa! Whoa!" Frank barked. "I am not having this conversation with my dog."
"I'm sorry, master," Rex said. He had meant to share that he had also felt strange feelings in Xander's presence, but Frank's reaction had put the kibosh on that confession.
Frank whimpered again. "I'm so horny," he whispered.
Rex looked confused, but then memory provided context. Now that he could understand the problem, he came up with what he hoped might make the situation better.
"Roll over," he said.
Frank felt compelled by all the intense training he had given Rex. He rolled onto his back. An instant later, Rex caused Frank to yelp in surprise when he used the sole of his boot to rub Frank's emerged penis.
"Oh, stop," Frank moaned.
"Sorry, master," Rex said and started to remove his boot from the vicinity.
"No, don't stop," Frank begged, and Rex, giving a bit of confused shrug, resumed the massage of the inflamed member with his boot.
Frank panted heavily as Rex moved his boot faster and faster, side to side. "Oh, fuck!" Frank howled as he released.
Rex stopped. "Did that help?"
Frank barked a weak affirmation as he tried to get his breathing back under control.
They heard the glass door slide open. "Is Rex OK?" Xander called.
Pant! Pant! "Tell him I am fine," Frank said.
"He's fine," Rex said.
"Well, hurry back," Xander said. "Dinner won't be long."
Rex straightened to his full height. "I should go inside or I will make your friend suspect something," he said.
Frank managed to nod his head. Once Rex walked back into the duplex, Frank felt a complicated rush at the realization that his own dog, albeit now in Frank's former human form, had just gotten him off.
Bothering him even more, the fact that it had felt so damn good. He wanted to feel it again.
"No!" Frank told himself. He needed to make sure he focused on doing what he could to remain human, at least in his mind, and not indulge every doggie urge that came his way.
He would have a talk with Rex, and simply explain that no meant no, no matter what he might do or say to indicate otherwise.
"Oh, fuck," he said between his heavy panting.
