Mikey was home from college, the summer heat was getting to him just a little. The AC at his house was broke, all he could do was lounge around waiting for time to pass. He was 19 years old, filled with slim muscle from being on the swim team at college, and was bored out of his mind. The black spotted Dalmatian had been at home for a week now, and nothing interesting had happened. Currently, he was sitting back on the couch, sweating from the heat, and panting heavily, tongue rolled out. His mother came out of the basement,
"You know, it's not right for a grown man to be sitting around the house all summer Michael"
He rolled his eyes, his mother had been on him since he got back, "Yeah well what am I supposed to do mom? No jobs nearby!"
His mother shook her head, "Well, if you're so eager to not even look, I think i found something for you, or you could shovel mulch like last summer."
The teen shutter in memory, the stink, the heat, the fat man yelling at him day in and out, not again. 
He groaned, Alright, fine mom, what is it?"
The mother dog rolled her eyes, "Well, Ms. Teppet and I down the street were planning on having a girls weekend, but her babysitter dropped out at the last moment, I was thinking that you could take the babysitter's place, it pays well, and it'll get you out of the house."
The teenaged dog thought it over while fanning his blue sports jersey, it was either this or shovel mulch again, and he'd rather eat a plate of molded cheese than work for that bastard again.
"Alright mom, I'll do it,"
He groaned, and got off the couch, "I'm guessing that it's tomorrow?"
The mother nodded, "Yep! And don't look so down, they have a pool, and I hear that Conner loves swimming too."
The teen started to grin a little, a bit of swimming while looking after some brat wouldn't be too bad. He stretched, and asked, "So, would i need to bring anything over?" 
The mother shook her head and sighed, "No dear, I'm sure she'll leave you some money for food and you just need to bring your own clothes. It's not that hard, just making sure he doesn't get into any trouble or get hurt and you'll do fine."
 

The day went by fairly quickly after that, and before the dog knew it was Friday. Mikey was at the door by 10 am, he slung his duffle bag over his shoulders and knocked on the plain white door. 
He heard, "Just a minute," from the other side. A few seconds later a human middle aged woman opened the door. She had a suitcase behind her, "Oh, you must be Michael, come in come in, I'm just about to leave but i can show you around."
The dog nodded and walked inside, it was a fairly standard suburban house, pictures of a single mother and a son were posted on the wall. He guessed that was Conner, the most recent picture showed a 10 year old boy with light blonde hair at a theme park, holding an ice cream cone while his mother stood next to him smiling. 
The dog was lead to the kitchen, where that same boy appeared eating a late breakfast. The woman spoke up,
"Ok Conner, this is Michael, he's going to be watching you while I'm gone ok?"
The boy looked up from his breakfast and said, "Ok mom!" and went right back to his game, the mother showed him over to the fridge, "On here are some numbers in case of emergency, i'll be out of contact most of the weekend, i've left $50 for food for the two of you, keep receipts if you can, he's to be in bed by 10 pm at the latest and no friends over, for the both of you ok?"
Michael simply grinned and responded, "No worries Ms. Teppet, you and mom have some fun alright? I'm sure Conner and I will get along great."
The mother gave a sigh of relief and said, "Alright, now be good Conner, do what Michael says, alright? I'll see you Monday."
The boy put down his fork and ran up to his mom, giving her a hug, "Bye mom! I'll miss you!"
"I'll miss you too, bye honey!" and with a quick peck on the boy's head, the mother was off, out the door and into her car. Leaving Michael and Conner alone. 
Michael looked over at Conner, "Sup' little man, you mom said that you guys have a pool?"
The boy looked up at him with a smile and said, "Yeah! It's really big and I have a ton of pool toys and water guns and noodles and rafts!" 
The dog nodded his head and said, "Right on, maybe after your breakfast we could change into trunks and take a swim, sound cool to you little buddy?"
The kid's face lit up, "Yeah! Awesome! Mom never plays in the pool with me anymore, thanks Michael!,"
The teen smiled and said, "Call me Mikey from now on, alright, Michael's what my mom and your mom call me,"
The boy giggled and went back to his eggo waffle and hashbrowns. 
The dog jerked a thumb behind him, "Alright man, I'll just go set up my bag and once you finish up we can have some fun!"
The Dalmatian walked up the stairs to the spare bedroom, right across from the kid's. He went  into the guest room and threw the duffle bag on the floor. He unzipped the bag, pulling out a pair of bright red trunks.. He slipped off his running shorts and briefs, letting his canine sheath and round, furred, plump balls hit the air as well. Felt so good to let them out after being sweated up all day. The sheath was about average for a Dalmatian his size, the fur around the sheath being white and hiding a rocket red tip. The area around it had darker fur, very much like pubes.  He chewed his lip and grinned a little bit, and idea forming in his head. Conner seemed a bit 'shut in' maybe he could try to get away with a thing or two. He simple flung the trunks over his shoulder and walked over to the boy's room, ass exposed and tail wagging. He opened the door and took a look inside. The kid's room was just a bit of a mess, last night's pajama's laid on the floor and the bed was unmade. The bookshelf was full of classic kid's books and the lucky little boy even had a tv with a gaming system with it. Damn, Mikey was never that lucky. He walked in and made his way to the boy's dresser. He pulled open the bottom drawer and found a pair of blue swimming trunks. He grinned slyly and took the swimming trunks and closed the dressor drawer. He made his way downstairs. The boy just finished eating his hashbrowns when he saw the dog come around the corner, bottomless. His mouth hung open just a little and the teen shrugged his shoulders, "What's wrong?"
The boy looked down, seeing the dog's sheath and pubes. The balls still swung just a little as the Dalmatian stopped, he felt a sorta funny feeling inside of him, "You're um....you're....naked sorta..."
The teen scoffed just a bit and said, "So? Don't you walk around like this when you're alone, we're all guys here and it's nothing you haven't seen before right?"
It actually was pretty new to Conner, the sheath was so different and much bigger compared to his own equipment. The balls were huge too, looked very weighty, and he coulda sworn he saw a little red tip at the end of the sheath.
The boy could only blush as he stared at it, "N-no, mom says that it's not right to walk around naked."
Mikey rolled his eyes, "Yeah well I bet your mom doesn't let you eat ice cream whenever you want either, moms don't know everything." 
The boy found himself staring at his babysitter's crotch, he asked, "Why's yours so much bigger than mine?"
The teen rolled his eyes, "Well, because i'm older, duh, you've got smaller parts because you're smaller, i got bigger parts because I'm bigger."
The boy nodded, understanding, that small red tip started to push out just a little bit, "What's going on?!?"
The Dalmatian only grinned, "Well, I'm getting hard, boys get hard when they're excited about stuff."
That tip poked out and kept growing, it was really red. The teen even put his paw around it and moved his hand back and forth a few times until it stood completely erect. The boy had no idea what to say, "Uh.....why are you excited?"
Mikey replied, "Well, because we're about to go swimming!"
He dangled the boy's swim trunks on his finger, "now come on let's get dressed for the pool!"
The boy could only meekly nod, he got up from the table and padded over to the teen. He reached her arm out but before he could react, Mikey reached out and grabbed him, pulling him up by his waist, "Raaahhhh I've got you!"
The boy giggled, forgetting about the teen's pantslessness, laughing with excitement "Hey! Come on! Let me go!" 
The Dalmatian carried him over to the couch swinging the boy around as they both laughed and giggled, Mikey's erection swung from his hips. Using the opportunity to feel up the boy a little, his soft belly and soft ass in particular, he gave the butt a little squeeze, finding the yielding ass wonderful.  Finally, they reached the living room couch where Mikey plopped the boy down, landing of the soft cushions. The boy landed on his back and looked up at his babysitter, who looked at him strangely. 
"What is it Mikey?"
The babysitter looked at the boy, his cute eyes looking at him, "well, we should get you changed into your swimtrunks yeah?"
Conner looked up at the dog, and was confused until he felt the older teen's hands, move downwards, across his stomach, the dog ran his paws down the boy's body, lightly touching that soft skin of his where Mikey could get away with it. Finally, his fingers curled around Conner's waistband, and the boy could tell what the Dalmatian wanted. 
"WAIT!" he shouted, "Are you sure this is ok?"
"Trust me," he said, and with those words he began to slowly pull down the boy's shorts, underwear too. What was revealed to him, inch by inch was a lovely petite cock, small, soft, and quiet different from his own. Mikey exhaled as he ran the boy's shorts down his legs and onto the floor, "You know...I was a little curious about what humans looked like too,"
His paw cupped they boy's  balls in his hand, they were soft, and so very small. Mikey doubted they even dropped yet. He played with them in his hands, lightly squeezing the balls and lightly shifting the sack. The boy was obviously uncomfortable with the attention. He squirmed and wiggled as he was touched, he asked, "Are you sure this is ok?"
Mikey replied, "Shhhh, it's alright, i'm just sating my curiosity."
The moved his hands away from the underaged sack and with his thumb and forefinger, began examining the boy's soft shaft. It was all external, unlike his soft shaft. The small head was covered in a type of skin which peeled back. The boy gasped as he did so. And the head was a strange color, a cross between light red and the boy's natrual skin color. He played with the penis a little more, wiggling it a bit and seeing if he could get the boy hard. He remained soft though, and finally he said, "Alright, well that's one question answered, come on, let's go swimming, i'm looking forward to seeing all those pool toys you were talking about." 
The could only nod his head and gulp, that was really weird for him, no one ever touched him there but a doctor and that was only for like, a few seconds. He stammered out, "O-oh, alright Mikey...." He quickly grabbed his blue swim trunks off the floor and put them on, glad to be clothed again. 
 

The two had a good time in the pool, Conner tried to forget earlier and actually had a great time with the college boy. The splashed, they swam, marco polo, and the entire time was filled with laugh, fun, and energy. Afternoon started to come, and lunch was eaten, so the two headed inside. The backyard entrance was in the kitchen, so when they went inside Mikey spoke up, "Hey, let's get these wet shorts off of you, can't have you walking around the house sopping wet,"
The boy felt his heart sink just a little as he felt those paws on him again, feeling his lithe body. "It's ok...you don't need to..." 
But his protest was useless, Mikey already slipped those shorts off of him and they fell to the floor with a wet smack. A few seconds later, another wet smack was heard and Conner looked behind him. The teen had also removed his shorts, and was hard again, that red doggy cock was throbbing, standing tall and proud, Conner let out a nervous laugh and asked, "What are you excited about now?"
The dog, looked at him and said, "Why don't i give you a little lesson?"
With that, the 19 year old picked up the 10 year old and held him close to his chest. The fur tickled the boy's skin as he was carried over to one of the wooden kitchen chairs. Mikey sat down, and had the boy in his lap. His hard puppy cock resting on the boy's bare ass, but pushed down so that way it came out between the boy's legs. Mikey started to talk and slightly hump the boy, his bare skin and pressure feeling good. 
"See Conner, there's more than one type of excited."
As he said this, a small amount of pre leaked from his cockhead, he reached a paw around and fondled his member, "And boy can get sexually excited, meaning they wanna have sex. When that happens, their cocks get really hard, and it feels really good to touch." 
The boy could only stare as the Dalmatian's paw started to move back and forth. The base of the cock resting on his ass felt really hot, "So...you're sexually excited right now?"
The Dalmatian started to move his paw just a little faster, "Uh huh, that's right little guy," 
He moved his other paw around and pulled the boy closer to him, who whimpered, feeling really uncomfortable, "Who....who do you want to have sex with Mikey?"
The teen gave a soft grunt and lent down, he whispered in the boy's ear, "Why....I want to have sex with you Conner,"
After he whispered this he gave the boy's cheek a small kiss and then whispered again, "You know what feels even better than me touching my cock...it's having someone else do it."
He stopped masturbating and moved his left paw to one of the boy's arms, grabbed the forearm, and started to move it towards his now twitching cock. The boy gave a bit of resistance at first, not wanting to touch it, Mikey whispered, "It's ok, nothing's wrong, it's not going to hurt you."
With those words he placed the boy's small fingers on his cock, who wrapped them around the length. Mikey groaned as he felt the boy's hands. 
"That's it, now why don't you move them back and forth."
"Do i have to Mikey?"
The Dalmatian didn't answer at first, he slid himself down on the chair so that the boy was resing on his hips now, cock at full mast and right in front of him, and finally he said, "Yes, kid, yes you do."
He whimpered and moved his hand back and forth, the cock was pointing directly at his face now. Ever stroke made it bounce up and down. Mikey closed his eyes, "Oh that's right little bitch, keep doing that, you're doing just fine."
Conner was hoping it would be over soon, so he kept on pumping the cock. Eventually the dog whispered in his ear again, "My knot's coming out, get your hand down my sheath and pull it out ok?"
The boy whimpered, he couldn't' help but do what Mikey said, he reached lower and felt a really hard part of the cock, much thicker. He reached his fingers down the hot sheath and pulled the fur down, revealing a huge bulb of flesh.
"Mikey! It's so big...what is it?"
Mikey spoke up, clearly annoyed, "Did i say stop moving that hand kid?!?"
He whimpered again and started to move his hand, more pre fell onto his belly. 
"That's my knot Conner, you did a good job. Now touch it,"
Conner moved his hand lower, gripping the knot with his hand, the larger teen holding him groaned with pleasure as he did so, "What's the knot for Mikey?"
The teen whispered in his ear again, panting heavily, "Well, when my cock gets buried in a little bitch's asshole, the knot gets pushed into his ass to make sure he doesn't go anywhere, to make sure that all my cum fills his ass."
The boy shivered and asked, "What's cum Mikey?"
After a few seconds of silence the Dalmatian moved the boy's hand away from his cock. He stood up, letting the little boy slide off of him. Conner felt like crying a little, he missed his mom. "Well, why don't I show you, you gotta wash all that pre off your chest anyways."
He roughly grabbed Conner's arm, and began to drag him upstairs. The boy started to cry just a little, "I don't want to learn anything anymore Mikey!"
The dog rolled his eyes, and forced him into the bathroom. He swiftly locked the door and turned facing the little boy, who was done crying now. 
"Ok, we need to was all the pre off your belly and chest, so come on in," 
He really didn't give Conner a choice; he grabbed his wrist and pulled him into the tub/shower combo. He turned on the water, it was pretty hot at first but mellowed out into a warm downpour. Mikey's large paws roamed all over his chest, not even bothering with soap, the sex fluids washed right off the 10 year old's body. Conner thought he was done, until he saw that Mikey's length hadn't gone down at all.
"Hey, bitch, you know how it felt great for me when you used your hands to paw me off?"
Conner felt a hand wrap around the back of his head, and slowly his face was pushed further towards the throbbing red cock, which was at eye level. "Well, open your mouth, this is going to feel even better."
The kid opened his mouth, and accepted the twitching red mass of flesh into his maw. He tasted salt, bitterness, and....a meaty flavor as it tickled the back of his throat. Making him gag just a little. Thankfully, Mikey showed just a little mercy and pulled his tip out from his throat just a little. Mikey used his other hand to caress the boy's cheek, "Now that's a good little cub, this is where you belong, a cock down your throat and loving it."
Conner scrambled to catch his breath with that huge cock down his throat. It was pressed just a bit deeper before being removed entirely by Mikey. The kid fell backward, landing on his ass and coughing, trying to breath. He put a hand on his chest, then inhaled, exhaled deeply. He was about to scream something at Mikey, but his words were cut short by the feeling of strong paws moving under his armpits. He was being lifted up again, the dog licked his lips as he studied the boy's features, turning him around to stare at the boy's small, tight ass. He threw the kid over his shoulder, turned off the shower, and carried him out of the room with a hand on the boy's butt, squeezing and pulling the cheek apart, "Oh i know what to do with you next."
The boy didn't even struggle, after the throat pain, even these weird squeezings on his butt were nice. He found himself heading towards his own room. Mikey threw the kid onto the bed, who bounced a few times, before Conner could even react, the teen was on him again. This time licking the poor boy from top to bottom. Tasting him, his legs, his balls, which really tickled, but in a bad way when he did so, and finally he swirled his tongue around the boy's nipple. 
"Mmmmmm, nice and pert," Mikey gave a small suckle and immediately the boy cried out, it was way too sensitive for him, "Like a little nubbin for me to lick."
The dalmation continued to swirl his tongue around that sensitive bit of flesh, enjoying the panicked sounds the kid beneith him was making. He also began moving his hand up his legs, feeling the small, smooth, hairless limbs fill in his hands. Finally, he reached that pert little ass, so soft as he pressed his hand in, grabbing a handful and squeezing as he kept licking that pert nipple the boy had. Conner tried to throw the Dalmatian's head off with his hands, but they were too weak, the older teen's head stayed right were it was, torturing him. 
With a particularly loud pop the dog left the boy's nipple alone, it was a bit red from being overplayed with, "God damn, Conner, you're probably the best boy I've ever been with."
With those words he began to focus on his ass more, spreading, touching and even reaching down with both hands, putting the human's legs behind his head. After a minute of kneading, groping, and pushing, he grew inpatient and flipped the boy onto his stomach, who whimpered out, "Could you please stop?"
The teen lowered his head and spreaded that boy's ass out, revealing that tight pucker hidden behind, "No can do kiddo," he lent forward and gave that tailhole a lick, it was just a bit bitter with no musk at all, he loved it, "You taste way too good to stop."
With that he dove his head down again, pressing his tongue against the boy's ring, licking it hard, trying t get it to relax. Conner could only pant as this new sensation made him both blush and humiliate him. He hated that wet warmth wiggling around his backside, he closed his eyes and tried to block it out, but then that wiggling, hot muscle broke through his ring, making his gasp out in surprise.
Unable to talk, the dog just pushed his tongue as far in as he could get it, covering the boy's ass with slobber as it went deeper and deeper into the kid. He tasted amazing; mikey coulda eaten that ass for hours if it wasn't for the throbbing red length that he was sporting. He gave the boy's ass a powerful squeeze pushed his tongue into him one last time before he pulled his tongue out, rimming it around the hole as it slipped out. He panted from arousal, while Conner tried his hardest not to cry.
When the big bad babysitter pulled his tongue out, Conner looked over his shoulder and asked, "Are you done now?"
The boy didn't see the dog. This was his chance to get away. He slipped off the bed and made his way out the door. He decided to crawl on the floor, hoping the teen wouldn't see him. But then he felt two furred paws around his waist and his heart sank, "Where are you going little buddy? I was just trying to lube up my cock for you and you decide to run away on me?"
He quickly brought the kid back to his room while the boy struggled, trying to break free, "I was gonna go easy on you and not force my knot into you, but seems now like you need to learn a lesson."
He sat down on the edge of the bed; with both hands he positioned the boy's ass over his cock. He moved him around until his lubed up tip was kissing the boy's tailhole. The boy's eyes shot open as he remembered what the dog said earlier about having sex. He struggled for just a little more before the dog clasped a hand over his shoulder and began to sink that hard length up the boy's ass.
The pain was huge, mitigated just a little by the lube and the rimming, but being spread so wide so quick made the tight little boy scream out loudly as he was violated. The cock's first in was in him and already he felt like he was being split in two. The dog groaned out in pleasure, never having something so tight and warm around his cock. It clenched and spasmed unconsciously, making it all the sweeter for Mikey. The teen gave a slight exhale, while Conner didn't even try to hold back the tears, and began sinking further into the boy. The pain didn't increase....but it didn't go away for the human either, his tunnel never feeling this full before, it was so strange...and awful. He didn't have the energy to squirm anymore; it was being fucked out of him. He could feel it pushing deeper and deeper, all the while the dog just kept pushing down, running into just a little resistance, which he solved with a quick thrust and a loud yelp from the little cub in his lap. Finally, his knot kissed the boy's tailhole. The kid reached down with his hands and felt the cock in him, it's outline just visible on his flat tummy, he groaned in pain, the penetration was the worst of it, and his hole was starting to not feel so....terrible. With a kiss on his cheek the Dalmatian began to move his length out. The boy was relieved, the sex was over...maybe he could go to bed and hope Mikey was nicer tomorrow. But as he felt the tip reach his ring, the dalmatian pushed him down again, faster this time, not being nearly as gentle. The boy gasped out, eyes bulging and tears forming again, then the awful reality hit him as he felt that cock move out again. The Dalmatian trusted in again, humping up into the boy, not caring anymore. He had a steady rhythm going as his knot kissed the boy's hole with every thrust up and push down. Instead of using his shoulders he was now using both of his hands around the waist of the kid. Pushing him down to meet each thrust. The boy could only groaned and prayed for it to be over soon. 
 

The teen was in heaven, those hot, tight inner walls gripped him like nothing else. He kept pounding away, grunting and moaning as he did so. He was starting to get close, it had been awhile and he had rutted into the boy for a good ten minutes. As he felt his orgasm approaching he gripped the boy and on shoulders, lifting him up and down, being far more erratic. Finally he lustily whispered into the boy's ear, "God damn, hope you're ready for this kid." and with that he shoved the boy down onto his knot with wall his might. The boy screamed in pain, the hole stretching to its absolute limit as it was forced open around the knot. He felt it slip in finally and the Dalmatian groaned out in pleasure, orgasmic bliss. He felt to his side while he came, bringing the kid with. Ropes of cum shot down the boy's ass, making that stomach bulge just a little bigger. The kid coughed from screaming so loud and tried to crawl away, desperate to get away, but found the knot tugging him back towards Mikey. The last few twitched of the cock died down and Conner was left feeling very full indeed, both of them were left panting for a minute until Mikey gasped and said, "See, that's what happens when you try to get away."
 

They stayed tied for awhile, Conner holding back his tears and Mikey rubbing the boy's chest, tweaking his nipples and whispering sweet nothings into the boy's ear. Finally, the knot deflated and the Dalmatian was able to pull his cock out of the boy, which was red from abuse. Milky white cum leaked out of the boy's hole and stained the bedsheet. Soon, they both drifted off into sleep, Conner passing out from exhaustion from his rape and Mikey from raping the boor boy.
 

Soon morning came, and Conner was the first one to awake, his tailhole was sore from yesterday's abuse and the arms of the teen wrapped around his stomach made it clear that it actually happened. Conner tried to wiggle his way out of bed but his movements brought the teenage boy out of sleep. "Mmmm, hello there little pet, I have some wonderful ideas for you today."
 

The boy shivered and said, "Please, I don't want to do anything else today, it really hurt."
 

The dog put a finger to the human's quivering lips and said, "ssshhhhhhh, if you go along with it today, I'll be gentler, if you wanna fight me, well, it's gonna hurt a lot more for you ok?"
 

He whined but nodded his head in agreement, the sting of roughness still radiated form his red tailhole. He didn't want to hurt. With that, the Dalmatian took his finger away and lent down, kissing the boy on the lips, tongue passing through and tasting his mouth. They made out for awhile, Conner felt that hard shaft poking his leg again. The Dalmatian pulled away and said, "That's a good boy,"
 

They went downstairs, naked, at the 19 year old's insistence. As the Dalmatian drank his morning coffee, he forced the boy's throat around his cock. That tight little throat enveloping his cock, Conner gagged and silently protested of course, requiring the teen to grip the back of the boy's head and thrust his cock down once or twice as a silent reminder of what resistance would get him. But soon enough, with a shuttering groan, Mikey filled the boy's stomach with spunk. Conner choked and sputtered as seed filled his throat, trying to drink as much of it as he could. He still ended up with a painted face once it became obvious to Mikey that the little bitch couldn't handle it.
 

"There you go, now why don't you clean up and we'll have some more fun later?"
 

Conner could only nod as one last spurt shot a rope directly onto his face, making cum drip down his cheek. The rest of the morning was thankfully tame for him. They watched some cartoons, which was nice. What worried the 10 year old was the fact that Mikey was almost always masturbating. Sure enough after a few hours of cartoons, the boy felt those strong hands lift him up, and position him directly over that throbbing cock. Because he was more willing, Mikey decided to be a bit gentler. He slowly speared the boy's ass, giving him time to adjust. That tight, tight ring still hurt, but Conner wasn't in as much pain as before. Slowly, he was lowered, the boy tried to watch the cartoons; it helped keep his mind off of the cock up his ass. Finally, he felt the knot kiss his tailhole.
 

He gasped, as Mikey thrusted into him, slower, more deliberate. It seemed that he was going slower this time, watching the cartoons as well. His hips rolled into the boy's ass, that red cock going in slow but hard, pushing deep into him. Those thrusts got faster and faster, eventually, the Dalmatian was moaning and panting as he claimed that ass. He couldn't take it anymore and with an arm wrapped around the boy's chest, he fell from the couch onto the ground, taking the boy with him, forcing him into doggystyle as he greatly increased his thrust, slapping the boy's ass as he held back tears. Finally, with a loud groan and a particularly violent thrust forward, he knotted the human, filling him up with seed once more. It didn't hurt as much as last time for Conner, but it was still degrading.
 

Saturday passed, with more random rapes for Conner, shifting from blowjob to being fucked and ending with Mikey falling asleep while knotted in that tight little ass once again. The only solace for him was that tomorrow Mom would be back, and he'd never see the Dalmatian again.
 

Sunday, Mikey knew his mother would be here soon and wanted to be rough one last time. He woke up first, that bare ass teasing him. He was instantly hard and as gently as he could, he positioned his cock right where the tailhole was, and began to cover the boy's mouth, who slept breathing through his nose. With an evil grin and a free hand, he gripped the boy's hip, and with only last night's cum as lube, he penetrated the boy with a violent thrust forward.  His cock pushed into him about halfway, the tight hole only allowing so much at once. Conner woke up screaming, but that paw kept him quite, tears rolled out of his eyes once more and Mikey whispered in his ear, "You tell your mom about this, and I'll do this to you every night, understand little boy?"
Without waiting for a response, he began humping the boy more, each thrust pushing him just a little bit forward, until he was at the edge of his bed holding onto the edge to keep him from falling off. By now he was so used to Mikey's cock that it hurt, but after awhile he could deal with it. He was just hoping mom would be back soon. Mikey felt paws on his shoulders and prepared himself. He relaxed his ass as best he could and felt that huge knot begin to push into him. After five agonizing seconds of force, is slipped in and the Dalmatian gave out a loud groan and began to cum. Conner felt that warm liquid fill him up, not nearly as much as the last 2 days, but It still made him feel so low. He just closed his eyes and waited for the knot to slip out. Sure enough, after a few minutes, the Dalmatian jerked his cock out, making Conner yelp as his ass expelled the cock. Exhausted, Conner fell back asleep, as Mikey got out of the bed, and began to clean up. He started with the smell, with some air fresheners, the heavy smell of constant sex was covered up, thankfully human noses are far less sensitive than his, so he knew he did a good job. Washrag in hand, he cleaned up any remaining dribbles of cum left behind, not wanting Ms. Teppet to find any mysterious white liquid in her house. Finally, he shook the boy awake and led him to the bathroom. He was tempted to force his cock down the boy's throat again, but decided against it. One shower later and a firm reminder of the consequences of telling on him, the boy looked fresh and fine....at least on the outside.
An hour later, the mother came back, "Oh Thank you so much Michael. Did he behave himself?"
The collage aged dog simply picked up his bag, looked over to the boy and said, "Yeah, he was very well behaved, you have such a good boy on your hands."
