Max groaned, slowly getting up, trying to push the big dog off of him. "Ok, I'm up!" He said, annoyed but still smiling. He pet Butch with a smile. "What's up? Wanna go out?"
Max nodded to the big Dalmatian, getting up, completely nude. He simply felt more comfy sleeping like that. He went to his drawers to pick out some jeans and a t-shirt, clothing himself in front of the dog.
Butch held in a whine as he watched Max get dressed. 'Why does Master insist on wearing those things? He looks so much better naked. And that penis...' Butch began drooling on the leash.
Max, only wearing his shirt and no shorts yet, bent over, looking for his glasses. Mildly annoyed, he talked to Butch, who had a full view of his nice, twinkish ass. "Did you knock the glasses off the table...?" He asked, sounding annoyed.
Butch's gaze remained fixed on Max's ass. His red cock started to come out of its sheath. He let out a whine in response to Max's question. He tore his gaze from the ass and sniffed around for the glasses.
Max searched with him. Their apartment was so small, they couldn't have gone far, right? He decided to search under his bed, still bottomless, sticking his head and most of his torso under the bed with his rump held high out of the bed. "I think I see em...Butch, can you help?"
Butch saw Max's cute little asshole and became overcome with lust. He walked over to his master and mounted him. His tip was just barely inside of Max.
Max shouted out, his virgin ass getting stretched out quickly by the thickness of the Dalmation's dick. "H-holy shit!!" He shouted, completely baffled by all of this, his wiggling only helping the big dog end up deeper in him.
Butch moaned and continued to slide deeper into Max. He didn't want to pull out, but, being an obedient pet, he would if Max told him to. Soon, his entire length was in his Master's ass.
Max let out a mix of a moan and a pained shout, panting under the bed as his own dick began to harden. "Boy...Butch..." he breathed out as he pushed naturally back into the dog, groaning.
Butch began to thrust into Max. His tongue started to hang from his mouth. He pawed at his Master's sides, trying to help him get out from under the bed.
With a bit of Butch's help, he did start sliding out from under the bed, but it only made the thrusting more rough. Max let out small, girly moans as the dalmation mated with him, but didn't do much to stop it. His cock was fully hard at this point.
Of course, Max couldn't understand what the dog was trying to do. It was a mix of him not understanding and him actually enjoying the fast thrusts of the dog, his hips helping him along.
Butch barked loudly as his knot entered Max's ass. An audible pop could be heard before the large dog shot his seed into Max's rectum. 'If only we could have children together...'
Max shouted out with a moan, the painful knotting only barely eclipsed by the pleasure of hot doggy seed entering him. He came at the same time, shooting his seed all over the floor, panting.
Butch panted heavily amd licked his Master's cheek. Once his knot deflated, he pulled out and backed away, fearing punishment. His tail hid between his legs.
It took Max a minute or two to recover, but he wobbily stood after a while. He gulped, blushing as he sat and looked at his dog, Butch. "T-that was mean..." he said, spread-legged and still blushing and panting. "Coulda warned me...but it was good."
