Best Birthday Ever Adam rushed off the school bus, the short claws on his footpaws scratching against the sidewalk as he ran excitedly back to his house. Today was the hyena boy's 10th birthday, and he had invited over a bunch of his best friends for a sleepover. He was so excited he felt like he would burst! They were going to eat pizza and cake, eat lots of candy and junk food, and stay up all night watching cartoons in their underwear. He really couldn't wait! As the boy ran around the corner and started up his driveway, he rolled his eyes as he saw yet another strange car in the driveway. This time it was a pickup truck actually, a big white one with flood lights and a little rainbow flag on the back window, so small you might miss it unless you knew what to look for. His dad was at it again. Adam sighed and ungraciously swung open the door. As expected, his dad was bent over the side of the couch, naked except for his jockstrap and a 5-point chest harness. Behind him a muscle bound bengal tiger was pounding away at the older hyena's backside, pants around his ankles and in the throes of ecstacy. "Ahh! Oh fuck Adam, you're home early!" His dad gasped out, seeing the boy step inside and drop his school bag next to the couch. "Dad this is when I always come home, and I've got my friends coming for a sleepover tonight, remember! You've gotta clean up, they'll be here soon!" The boy whined a bit, trying to invoke a bit of guilt in his father. "Ahh, ahhH!!" the older hyena gasped out, the Tiger looking a bit astonished but not skipping a beat as he continued driving his cock deep into the boy's father. "I.. I will son!" he nodded, his face flush. "Come on stud, blow that load in me, there's gonna be a bunch of kids here soon!" "Ahh fuck, I'm.. I'm trying, I'm close!" the tiger grunted out, his voice low and gravely. "Will this help?" Adam smirked, climbing up on the couch, he grabbed his father by the chin and tugged down the front of his own shorts, shoving his half-hard 10-year-old cock right into his father's muzzle. The older hyena groaned and immediately accepted it, tongue lavishing his boy's cock right there in the living room. "Oh fuck man, you let your own kid do that to you? Fuck you are one hell of a bitch!! I... oh fuuuuck!" the tiger roared, which Adam assumed must mean he was finally blowing his load up under his dad's slutty tail. He delivered a few more thrusts, finishing himself off, then pulled out with a wet sloppy sound, wiping his cock on the older hyena's tail. "Yeah, my dad's kind of a huge bitch." Adam pulled his cock back as well, leaving his dad there panting and dripping. "Heh, yeah I can see that. You kids have fun with him tonight." the tiger smirked, pulling up his pants and heading back out the front door. Hrmmm, Adam thought to himself. Maybe they would have some fun with him tonight. He waiting for the tiger to leave, then leaned down and kissed his father on the muzzle. The two moaned together for a moment before Adam drew back again. "Hey daddy, I want you to leave your harness and jock on under your clothes tonight, okay?" His dad blushed back at him, looking a bit confused. "Adam I don't know if that's..." "But Daddy obeys, doesn't he? Besides, it's my birthday!" the 10 year old grinned back, interrupting his father. "Yes Adam, but..." "Daddy, that's an order." Adam was firm this time, using just the sort of tone he knew his father would respond to. And indeed he did, the older hyena nodded obediently back at his son. "Good, now go put something on over that, unless you want all my friend's parents to see what a huge bitch you are too." he kissed his father again and gave him a pat on the rump as he stood back up. "Put a plug in too." he added, noting the thick streams of cum leaking out under his father's tail. That tiger definitely wasn't the first one to breed him today, and wouldn't be the last. --- Adam and his father had just finished setting up for the party when he heard the doorbell ring. The hyena boy squeaked in delight as he padded over to the door, swinging it wide open as his best friend Luke smiled back at him. The 9-year-old ringtail lemur lept forward and hugged his friend, they both giggled together as Luke wished him a happy birthday. Adam noticed something else though, hiding shyly behind Luke's father's leg was another ringtail lemur, Luke's younger brother by 2 years, Louis. "Sorry I had to bring Louis too, my dad said I couldn't come unless I included my little brother. Ugh, so laaame." the ringtail scowled back at his younger sibling. "Aw that's okay, Louis can join us too. We'll have lot's of fun, okay!" Adam said cheerfully, reaching for the younger boy's paw and welcoming him inside. The lemurs' father smiled down at all of them. "That's very nice of you Adam, you all have a good time tonight. I'll see you in the morning." he acknowledged as he waved goodbye to the boys and began padding back to his car. Adam led the other boys back inside as they started talking about what sort of cartoons they should watch tonight. Over the next hour or so, more and more of Adam's friends began to show up. There was Dominic and Danny, the two coyote twin boys. Jason, his shark friend arrived next. Then Miles, Owen, and Teddy, three cougar boys who were all cousins. Theo the golden retriever, and Hugo the elephant came together next. They were holding hands, and even though they hadn't said anything Adam was pretty sure they were boyfriends together. Even Cole showed up, he was a zorse, and was usually pretty shy at school. They hadn't hung out much, but Adam always liked to try and make new friends. --- The boys were all sitting in the living room laughing and talking together, passing the time while they snacked on cookies and crackers that Adam's father had set out. Some time later the older hyena walked back into the room, putting his paws on his hips and smiling at the boys. "Say, are you boys hungry for pizza?!" he asked excitedly. "Yeah!! Yeah!!" came a chorus of cheers from the boys. "I want pepperoni!" "I want cheese!" "Pineapple!" they all started callout out their favorite toppings. As Adam's father was writing all the orders down, Louis the little 7-year-old lemur spoke up and asked a different kind of question. "Hey um mister... Adam's dad, what's that clinking sound, do you have metal parts? Like a robot?" the boy asked innocently. Some of the other boys began to giggle, but Adam immediately knew what Louis was talking about. His father's harness must have been clinking a bit under his clothes, and the boy's sensitive ears picked it up. Adam interjected before his father could say anything, "Yeah dad, what is that sound? What have you got on under your clothes?" he grinned, leading his father on. "Adam I really don't think..." his father started again, once more cut off by his younger son. "Now daddy, what did we talk about earlier. You're going to be obedient on my birthday, aren't you?" Adam went on, maintaining that commanding sternness in his voice. His father blushed and nodded, unable to help himself. Several of the other boys watched, a bit confused, unsure why Adam would be talking to his father like this. "Now, take your shirt off and show them." Adam's dad was blushing bright red under his fur, but he did what he was told. He unbuttoned the front buttons of his shirt, sliding it off and handing it over to Adam, revealing the red accented black leather harness he was wearing below. The other boys all buzzed to themselves, the 3 cougar cousins all giggling and pointing, the golden retriever covering his muzzle in surprise while his elephant boyfriend grinned. Cole the zorse sat quietly in the back, suddenly crossing his legs and covering his groin with his hands. "What is that?" Louis asked out loud, completely confused by the whole situation. "That's a harness, it's so other people can tug him around. My dad wears it because he's a bitch." Adam explained, rather proudly actually, grinning mischeviously back up at his father. "Adam!" his father called out, the parental instinct in him fighting with his submissive nature. "Uh uh daddy, you know the rules tonight. You're my bitch for the party." He commanded with the voice his father couldn't resist. "My daddy says Bitch is a bad word!" Louis chimed in, still clearly a bit confused. "Sometimes yeah, but it's really the best word to describe him. It means he'll do anything you tell him to." "Stand on your head!", "Sing the ABC's", "Eat a snail!" the other voices of his friends called out, testing Adam's explaination for his father's attire. "Haha, no not stuff like that. I mean yeah he probably would, but it's gotta be stuff that embarasses him, and you can even put stuff inside of him! I'll show you, like this." Adam cleared his throat and looked back up at his father. The older hyena looked back at him helplessly, a bulge in his pants that was impossible to miss. "Daddy, take your pants off too, then show Louis what you have in your tail." The older hyena's paws were shaking, he knew he shouldn't be doing this with so many cubs around, but when Adam used that voice with him he just couldn't disobey. He was a bitch first, and a father second. As he dropped his pants, the other boys gasped again, some coming closer to get a better view. He was still wearing the jockstrap from earlier, his cock barely contained behind the strained pouch. Not that the older hyena was really all that hung, but there was no way to hide an erection like that. Next he turned and faced the wall, bending over as Adam had told him to do, revealing the base of a bright red buttplug stuck firmly up under his tail. "That's called a buttplug." Adam explained. Several of the other boys broke out in laughter at the funny word, echoing him in delight. Buttplug, buttplug, they chanted. "I'll show you why he has it in later, but I think we should give daddy bitch a break for now. His face is so red it looks like he's going to turn into a tomato." Several boys giggled again. "Daddy, go order the pizza, but when it gets here you're going to answer the door for the pizza man like that, okay?" he commanded. His father was in far too deep now, he nodded affirmatively and slunk back off to the kitchen. "Wow Adam, I can't believe you can do that with your dad!" Dominic the coyote exclaimed. "Yeah our dad would give us a real whoopin' if we talked to him like that." Dominic's brother Danny added on. "My mom talks to my dad like that sometimes." The shark boy Jason added his voice to the chatter. "But then they always go into the bedroom for a while." "For sex!" Teddy the cougar exclaimed loudly, his other two cousins rolling down on the floor next to him and laughing. "Uh huh, my daddy does that a lot." Adam continued to explain. "He'll have sex with anyone who tells him to, it's one of his favorite things." "Do you have sex with him?" Luke asked, Adam's lemur friend who had been mostly quiet up until now. Adam actually blushed a bit, he should have expected the question but it still surprised him that Luke would ask so brazenly. "Well... sometimes yeah. Usually it's other guys that come to the house, but sometimes I'll put my thingy in his muzzle while the other guy is putting his thingy in my daddy's tail. He's really good at it." "Do you think he would do that for me?" Luke asked, suddenly serious. "Um, yeah probably, if I asked him to. Let's do that later though, wanna get in our undies and watch cartoons?" Adam suggested, trying to change the subject away from his slutty father. "Yeah yeah!!" The cougar cousins all chimed in unison, taking off their shirts first and wiggling out of their pants. The three of them all had matching red, green, and blue Paw Patrol underwear with the heroes from their favorite show. The others followed suit, the coyotes were both wearing boxer shorts, Jason the shark was wearing form fitting black briefs that looked a lot like Adam's, and Luke helped his little brother out of his clothes first before stripping down himself, the two of them in tighty whities. Theo and Hugo helped each other out of their clothes, clearly not the first time they had done so together as they played a bit with each other's briefs, both with rather obvious erections. Adam changed last, watching all his friends get nearly naked as he pulled off his own shirt and dropped his pants, tossing it unceremoniously into a pile. "Cole, what about you? Don't you want to wear your undies, it's really comfy!" Luke asked the zorse, who was still sitting by himself and covering his groin. "I... I..." the boy stammered. "It's okay Cole, we're all doing it!" Adam smiled back, a few other the other boys standing up to watch. Cole looked around at all the other cubs in their underwear, taking a deep breath and looking up at Adam. "I don't have any." "Any undies? Did you forget?" Adam asked. "No I... I don't usually wear any. It's hard to find any that... fit." he blushed even harder. "Aww it's okay Cole, you can just be nakie! That feels even better!" Adam encouraged. "I can't I... I'm too... big." he buried his head in his hands, now unable to hide a very large and very stiff erection poking up his pant leg. "Woah! No it's okay Cole, that's a good thing! Look if it'll make you feel better, I'll get nakie too, then you won't be the only one, okay?" Adam suggested, putting his paws into his waistband and dropping down his undershorts without a second thought. The hyena boy's semi-hard erection hung down exposed between his legs, drawing the attention of the other boys, little Louis in particular. Cole nodded, giving Adam a thankful smile as he pulled off his own shirt. You could see even more of the zebra stripes covering his upper body, fading into a tawny brown the lower they went on his fur. He stood up next and unfastened his shorts, dropping them to the ground rather quickly and stepping out into the living room naked. The boy was certainly not being modest earlier, he was big! The zorse's 8" equine cock flopped up and twitched, very much larger than any of the other boys. "Wow, you are really big! Even bigger than my dad!" Adam exclaimed. "R.. really? But he's a grown up!" Cole looked astonished. "Yeah but he's a bitch remember? He really doesn't use it, other guys use him." Adam nodded. "I wonder what..." Cole began, before he was suddenly interrupted by the doorbell ringing. "Oh that must be the pizza! Daaaaad!" Adam called out. "Pizza's here! Remember what you have to do!" The older hyena stepped back into the room from the kitchen, still wearing his jock and harness, gasping a bit as he saw all the other cubs in their underwear, including his own son bare naked with another boy he didn't know. Adam giggled and followed his dad to the door. "Go on, open it." he encouraged. Adam's father cautiously opened the door, a teenage fox boy on the other side, dressed in his red and white pizza place uniform and carrying a stack of four boxes. The box began to speak without quite noticing what was going on first. "Okay, that'll be thirty four ninety... um..." the teenager paused, suddenly noticing the man answering the door was wearing less than normal attire for this sort of encounter. He blushed a bit, stumbling over his words until he heard a smaller voice speak up from somewhere below. "My dad will suck you off for a tip, if you want." Adam had suggested. "Won't you daddy?" The older hyena nodded, knowing he couldn't disobey. Much to both of their surpise, the fox boy nodded back and steped inside. He handed the stack of boxes to the younger hyena and leaned back against the door when it shut. Adam's dad knew exactly what to do next. He got down on his knees and fished the fox's cock out of his pants, wrapping his lips around the boy's hardening tip and lavishing with his tongue. Adam went and began distributing the pizzas to his friends, all of them watching the show from across the room. "That's a blowjob?" Luke asked. "That looks awesome." "Do you and Hugo do that?" Dominick asked Theo, the golden retriever. Hugo just smiled while Theo blushed. "Y.. yeah, sometimes. Adam's dad looks really good at it though." "Oh, he is." Adam affirmed, watching his dad work the fox boy over as he chewed a piece of pepperoni pizza. It didn't take long for the teenager to finish, blowing a load in the hyena's muzzle and pulling his cock back, gasping. "Holy shit mister, you're really good. Can you do that next time I deliver here?" he asked. Adam's dad just nodded, knowing he'd never be able to refuse. "T..thanks! I've gotta go!" the fox turned back out the door quickly, his pants dropping back down to his thighs as he quickly pulled them back up, forgetting the button. Once the door had closed, Adam called his dad over. "Oh daddy, I think Luke wants a blowjob like that fox. Why don't you show him how good it feels?" Adam's dad crawled over on all fours, in a state of deep submission as he came up to the lemur boy. Luke didn't know what to do with himself, but when the older hyena pulled the lemur's pre-teen cock out of his tighty whities and started sucking on his length, he couldn't do anything but moan. The other boys watched, Adam even started stroking himself, getting pretty aroused as he watched his dad's muzzle work over his best friend's cock. The young lemur grabbed the hyena by the ears and tugged them a bit, starting to buck his hips instinctively. "Yeah he really likes that, pull his ears harder." Adam grinned as he kept stroking himself. "Hey when do we get a turn!" Teddy spoke up, climbing out of his shorts and stepping up naked and hard right next to the lemur. His two cougar cousins followed close behind, stripping off the rest of their clothes and watching closely as the hyena worked the lemur over. "Go on daddy, my other friends need a turn too." Adam ordered, and his father obeyed. He turned to the 3 cougar boys, slurping their cocks one at a time, then bunching two of them together to lick both with his tounge while he stroked the third boy in his paw. Luke looked a bit disappointed that his treatment had stopped, until his little brother Louis looked up at him and said "I can do that too if you want." Luke didn't even stop to think about it, and moments later he was leaning back against the couch while he humped his 7-year-old brother's warm wet muzzle. Not wanting to be left out, Theo and Hugo stripped down and began 69'ing on the couch. The elephant's grey skinned cock was bigger than the other boys, but still not as big as Cole. "Hey Cole, I've got something special for you. Come here." Adam beckoned the boy over to his father's backside, where he had a paw around the base of the butt plug stuck deep inside. "Watch this." Adam tugged, making his father moan out around the cougar boy's shafts in his muzzle. He tugged again, a bit harder, the older hyena moaning louder. Finally he pulled the plug hard enough and it came out with a pop, a splash of cum going right along with it as the hyena's gaping tail tried to clench on the air. "You can just slide your cock right in there. Go ahead, it's nice and warm." Cole was being driven by his own hard cock now as well, Adam could tell this one was destined to be a stud. He pushed the base of his cock against the hyena's tailhole, not requiring much force at all for it to slide right in deep. He moaned out and stamped his hoof, thinking of nothing but the warm sensation gripping his cock. He instinctively began to thrust, just doing what his body told him to do, acting on his feral desires. The only one not getting serviced was Jason the shark, but he was taking a particular interest in what Cole was doing to the older hyena's backside, and was stroking his two hard shafts while he watched. Adam stepped back and took in the scene, all of his cubby friends now involved in the kind of debauchery he only dreamed of. He hadn't imagined his birthday sleepover would go quite like this, but now he couldn't be happier. --- This went on for much of the night. Adam's father had sucked on nearly every boy, and taken half of them up under his tail. When he wasn't sucking cock, little Louis was proving himself quite skilled. Even Adam had a turn on the little lemur's inexperienced muzzle, but couldn't deny it felt almost as good as his father's. Luke had tried stuffing his little brother's tail as well, but the boy was just too tight and he couldn't get it in. Adam told him they would keep practicing, Louis would be able to take cock under his tail in no time. Adam was starting to think that his best friend's little brother might be a bitch too. Theo and Hugo mostly played with each other, but even Hugo had a turn at the bitch Hyena's tail while his boyfriend Theo fucked the man's muzzle. They pounded him from both sides until they got the tingles, unable to go on. Most of them were unable to cum, which was the white stuff that his dad had under his tail as Adam had explained earlier. When boys get old enough, they shoot cum when they get the tingles, but so far only Cole seemed to be able to do that. Cole actually came 4 times. Twice in the Hyena's tail, once in his muzzle, and once he came all over Louis while the little lemur was licking up his shaft. Most of the boys were spent, some were even asleep, as Adam lay on top of his father with his own cock buried under his dad's tail. With Paw Patrol still up on the TV, Adam wrapped his arms right around his father's chest. His cock throbbed in the warm cum-slicked hole, and he leaned his muzzle up to his father's ear. "I love you dad, this was the best birthday ever." He knew his dad was exhausted, his body had been used multiple times by every cub there, but Adam could still tell when he was smiling. "I love you too Adam." he whispered back. The two of them fell asleep together, the son still locked inside the father.
