	"More rice, Sensei?" Raphael held out the bowl.

	Splinter set his chopsticks down on the blanket under them. "No, thank you.  I have had enough.  This has been a lovely picnic, though.  Thank you all.  It is good to get out of the sewer."

	Donatello took another slice of pizza from the box. "I didn't know they made vegetarian sushi pizza.  It's weird, but kind of nice.  Bit too much seaweed wrapper bits."

	Leonardo tapped his fingers together acting as patient as he could despite looking like he wanted to say something.  He'd been nervous all night, though nobody had said anything.  Splinter wondered what he wanted to talk about, but decided to let it wait until a more private time to ask.  His son clearly wanted to bring something up, probably without his brothers hearing.

	When he did say something, it was just small talk. "Other than the rain, it's been a very peaceful night."

	All eyes looked to Michelangelo the instant that was said.  They knew him.  He was playing with a phone and did not miss his cue to interrupt a peaceful moment.

	"HA, LOOK, Guys!" Michelangelo held up his phone. "I got a new app and it's HILARIOUS! See? Here's Donatello in a tux shirt and a tutu!"

	Donatello sighed, but his other two brothers snorted in amusement. "Hilarious."

	Mikey flicked through the screen again, then pressed a few more buttons before showing his phone again. "Here's Leo, uh yeah, that's the one, Leo in a football helmet and half a horse costume with high heels!" A few more button presses. "OH OH! And HERE is SPLINTER in a school girl outfit!" Splinter frowned while his other sons struggled not to laugh, but said nothing.  The fur on his cheeks did brighten a little as he flushed under it. "It's lots of fun.  It can turn any photo into something silly by pasting these outfits over it and letting you rotate the them."

	Raph covered his face, but couldn't keep it is. "Gee, Sensei, you look pretty cute in that.  Maybe you should try one instead of your robe."

	"Perhaps if you wear it first, Raphael.  I'm sure we would all look cute.  Just think how easy the foot clan will be to fight if they are busy laughing."

	Leonardo hesitated. "Uhhh, speaking of school girls...  You have a daughter, right, Sensei?"

	"You have fought her several times, Leonardo." Splinter let a real smile cross his face. "Do you doubt she exists?"

	"No no, of course not.  Um, it's just, if I wanted to DATE her, ONE, If I wanted to date a girl, what would be the best way to move to more, you know, intimate stuff? You've been with a girl, so what did you do to go further?"

	The smile on his father's face faded, though the blush on his cheeks visibly brightened the fur above it. "I do not really think that I am comfortable talking about that with you, my son."

	"Oh.  Ok.  Sorry." Leo hesitated. "How about just advice for dating her, then? You know, things to say or especially NOT say.  You're always good with words."

	Splinter closed his eyes and looked up for several long seconds in silence. "You are wrong, Leonardo.  I am not always good with words." He looked around them, looking far more uncomfortable than they had ever seen him out of a life or death situation. "I am not comfortable talking about that with you because I cannot.  I am afraid that I do not have much experience to talk about."

	Michelangelo paused with a slice of pizza near his mouth. "What?! But like, you had to have had SOME experience, Sensei! I mean, you did have some fun to make Miwa, after all."

	"That is partially true." Splinter let his normal peaceful and confident posture slide into more of slump of resignation. "However, I must admit that I was not exposed to women much at the dojo and certainly not before joining it.  Learning Ninjitsu was very intensive and exhausting.  We did not have the time or even the energy to invest in looking for love." He smiled briefly, then continued. "We certainly wanted to and some men did try, but they never lasted long because they could not focus on their training and did not have the energy if they got what the wanted.  Even later, when I had finished my training, I was always too busy to date, as you say, and while yes, I do have a daughter, it was one time and very quick.  We were both desperate for love, physical love, and could not take long to enjoy each other.  We spoke during very brief periods before that, it is true, but it was never what you boys would consider dating."

	Raphael and Leonardo had their mouths open at their sensei's admitted lack of experience.  Donatello whistled and looked up at the trees nearby, not sure what to say.  There was silence for several seconds.

	Michelangelo finished eating his pizza and waved dismissively. "Psh, Who cares about that, dudes? What do you need a girl for, Leonardo? You got us! Heck, you had ME just this morning! I'm still sore sitting here.  You are WILD back there, you know that?"

	"MIKEY!" Leonardo looked horrified as he yelled it.

	"What?! It's  true!"

	Raphael leaned over. "Not in front of SPLINTER, remember?"

	"Huh? Oh... right." Michelangelo smiled nervously. "Sorry, Sensei."

	Splinter looked from one to the other in surprise. "You are sexually active? How? With whom?!"

	Donatello and Leonardo were quiet.  Raphael looked uncomfortable and even Michelangelo looked nervous.  Their father took a deep breath, but said nothing, waiting.

	Finally Raph shrugged. "Yeah... kind of."

	"You know... uh... just kissing, touching,' Don gave a nervous cough and said 'sex stuff' quickly after it.

	"Sort of, with each other, sort of thing." Leonardo tried to sound confident as he said it, but wasn't very convincing.

	"I see." Splinter stood up. "I think that this picnic is over.  We will all go home now, I will take a different path, YOU will all go straight home after cleaning up."

	Mikey hopped up. "You don't want to go with us?"

	Their father turned to walk further into the park, pausing to look back to speak. "No.  I need time to think.  By myself.  Go."

	The turtles watched for a bit as he disappeared further into the park, then cleaned up the boxes, picked up the blanket, and walked home.  They were glad it was night and dark so they didn't have to look at each other on the way.  None of them were comfortable after how Splinter had acted.

	It was well over an hour after they got home that Splinter came back.  They were lounging around the lair, playing a game, reading, and sparring, but all of them stopped when they saw him.  Their father was wet from snout to tail and covered on one side with mud.  At least it looked like mud from a distance.  Closer up they saw noodles, soggy potato chips, and bits of cardboard stuck to him.  Closer up they also smelled him.

	"Sensei! Are you alright?" Leonardo ran to him first, then backed away at the stink of spilled garbage. "What happened?!" 

	"Leave me be! I am fine." Splinter leaned against the doorway and wiped water from his facial fur, his hand left a rather unpleasant streak of dark material along its path. "A car swerved to hit me with a puddle.  I dove out of the way, but there were bags of garbage piled up where I landed." The rat sniffed at his hand and winced. "Very spoiled garbage."

	"We gotta get you clean, Sensei." Raphael grabbed his messy hand before their master could say he didn't need help. "Come on."

	His three brothers hurried forward to grab Splinter's other arm and push from behind.  He resisted much more than he normally would.  All of them hoped he wasn't too angry with them from what they had revealed before.

	Splinter tugged back a few times before finally letting go.  The thought that he was being foolish about it slid through his mind and he knew they were right about cleaning up.  Even if he was still upset to find they had been intimate with each other it was childish to stay filthy.

	He smiled faintly. "Very well, you are right.  To the shower then."

	Hands ran over his back and Donatello's voice came from behind him. "And then to our spa, you really need to relax, Sensei.  You're way more tense than is good for you."

	"Onsen." Splinter chuckled.

	"what?" The boys said their own variation on the word together.

	Their master sounded very tired and somewhat out of it as he responded. "It is an onsen, not a spa.  I've always liked that word better.  It reminds me of Japan.  My own onsen to bring me back."

	The four turtles looked at each other, then hurried him to the shower.  Four hands tugged his robe open, then four more fought each other to undo the sash holding it closed.  Michelangelo was left holding it when it came off but he simply tossed it onto the floor to deal with later.

	"We've got you, just relax." Leonardo and Raphael held his hands while Donny adjusted the water temperature. "Maybe we can make up for earlier."

	Splinter was quiet after that, simply standing with his arms out and his sons running their soapy fingers through his fur.  It felt quite nice.  Their strong hands worked up and down his muscles there, two turtles on one arm before one of them thought to brave his legs.  There had been a lot of spillage down there as he finished walking home.  The muck had been watery, but it clung to his fur tenaciously.  Donatello finally had to go grab some dish soap.

	The pair of hands running down hes legs started up at his thighs.  Splinter stared ahead, not sure he wanted to see who it was down there.  His children were sexually active after all.  Would they be looking at him as they apparently looked at each other? Was that all they saw anymore? They had said they kissed.  Kissing wasn't bad.  They also said touching, which also wasn't bad, but there had also been Donatello's sex stuff comment and Michelangelo's comment about Leonardo... that had clearly been sex.  Even if he hadn't experienced much himself, Splinter had seen enough television and read enough books to recognize that.

	It was hard to blame them too much though.  He had them cooped up in the sewer much of their lives, only ever able to go above ground in disguise at night.  They were touching each other though.  That couldn't be right, could it? Who else would they do it with? Splinter grunted at fingers sliding up and down his legs while he was thinking.  Anybody SHOULD want to be with them, when they were old enough, but he knew that many humans were very shallow creatures.  Probably no one would want to be intimate with them, even with as handsome and well developed as they were.  He wondered what his opinion of them would have been had he still been human and not their adopted father had he met them for the first time.

	There had been those at the dojo back in japan that he had considered handsome.  There had been Tang Shen, with whom he had had his only real sexual experience.  It had lasted only a few minutes and half of that had been stripping down enough to get to the act, but it had been wonderful while it lasted.  He had not gotten to see much of her bare body though he had very much wanted to.

	Fingers ran down his back, he wasn't sure who and he was glad of that.  They kneaded down his tense muscles and brought a grunt of gratitude from him.  Why was he so tense over learning that they had done such things with the only ones who would have been willing to do it with them? They were brothers and they were the only ones to know what they liked.  Would April have been willing to? Would his own daughter? Leonardo clearly hoped so.  Splinter decided not to think of her as his daughter and Leonardo as his son for that.  Son and Son was less problematic than son and daughter together, even if they weren't related.

	His tail clenched down almost as soon as he thought that.  Fingers had slid down his buttocks and curved around into his crease.  He could not stop himself from looking back to see Michelangelo back there.  The least tactful of his sons didn't have a mischievous look on his face, he simply looked like he was trying to wash.  There wasn't even a smile, at least not until he saw Splinter looking at him.

	"Oh, uh, heh, sorry Sensei.  I saw a bit had leaked sort of kind of... you know, down there and was trying to get at it.  I can leave that part alone." Mikey did not take his fingers out or stop scrubbing them despite saying it.

	It felt very strange to have another's hand sliding down his crevice.  The soap bubbles tickled against his tight wet ring and Michelangelo's strong fingers scratched quite nicely against rarely touched flesh.  Splinter wondered if that was how it had started for them, just one helping to wash another.  Something innocent probably.

	"You have all been washing together for years." He had to know. "Was this what started your sexual explorations?"

	"Huh?" Leonardo looked up from where he was crouched scrubbing Splinter's lower leg. "Oh, no.  Raphael found this magazine and then Donatello found some stuff on his computer.  They were really interesting."

	Leonardo's position gave him a perfect view between their father's legs when he looked up, but the boy was looking into his eyes rather than at that part of him.  Splinter was glad of that, at least until Leo glanced down at it and right back up again.  There was definite movement down there.

	"I see." The rat took a deep breath and tried to smooth his thoughts into a calm meditative state.  It didn't work. "You all seem to have gotten my clean enough enough.  We may relax in the Onsen now, I think."

	The Onsen was an abandoned subway restroom that been partially flooded when they had found it.  Once it had very expensive tiles, decorations, and lights in it.  Donatello remove all the stalls and everything that wasn't flat before installing a water heater, a water filter, and some better drains.  It had taken a week of work to clean up and get ready and another week to decorate with fake bamboo and wood along the walls.  Five stools and a couple large rocks here and there had been added later for things to sit on.

	It wasn't perfect, but Splinter had seemed happy with it and he was happy to see it again as they slipped into the water.  His whole body visibly relaxed.  Just having the garbage slime off of him had helped a lot, but the atmosphere did the rest.

	Splinter looked around while his sons took their own seats and soaked in the water. "It is always quiet in here.  Even in Japan it was quiet when I when I bathed.  We were all too tired to talk much."

	None of the turtles said anything.  They were worried about him and how he had acted earlier.  Michelangelo was worried about having been caught with his fingers in his dad's ass crack.

	After almost a minute of silence, Splinter lay back and let his head dunk under the water for a moment, before speaking with just his muzzle out of the water. "You have all kissed each other, then?"

	They weren't expecting the question, but after some shuffling in the water and more than one rubbing their necks in embarrassment, there were four variations on the word yes.  Splinter lifted his head out of the water to look at them one at a time. Somehow, he had not expected them to be embarrassed answering that, not with how Michelangelo and Donatello had spoken earlier.  He also wasn't expecting his own embarrassment by the answer.  At his age, just thinking about kissing shouldn't have had any effect.

	"Would you show me?"

	Donatello glanced at his brothers. "Um... you don't know how to kiss, Sensei?"

	"I do know how, but it has not been something I have experienced very often after being turned into a rat."

	"You want us to kiss each other?" Donny scooted forward. "Or do you want us to kiss... you?"

	Splinter was silent at that.  He didn't know himself what he wanted.  After their hands all over him and hearing what they had done his thoughts were a jumble of desires and confusion fighting with years of calm and control.  While they were clearly not human, they all looked handsome with their toned arms, legs, and torsos.  Straight, gay, anything sounded better than continuing to be physically alone.

	The movement in Splinter's groin earlier hadn't stopped on the short walk to the onsen.  He was erect.  His thoughts, their touches, and years of solitude weren't going to let it just go away quickly.  The turtles had all stolen subtle peeks at it, but they were trying their best not to look at it directly.  They were just as unsure as he was what to do about it.

	Donatello was closest to him on the left when Splinter had asked about kissing.  He wasn't sure what his sensei had wanted, but he was sure what he wanted.  Something he'd always wanted to try.

	After scooting over, he leaned in and kissed his father beak to muzzle.  Splinter looked surprised, but did not pull away.  His son didn't push hard into it, but just the touch of the teen's mouth to his was enough.  It really had been a long time since he'd had a kiss beyond a peck on the cheek.

	With no complaint from his father, Donatello went a bit further and rested his hand on his dad's stiff erection.  He could feel Splinter's heartbeat racing when he squeezed around it.  It was much faster than his brothers' cocks when he held them despite barely doing anything so far.  Their master was far more excited than he had expected, yet still pulled away at the grip."

	Splinter scooted back in alarm at the touch. "Donatello!"

	The turtle let go instantly. "Sorry, I thought you wanted to see what we did together."

	Raphael splashed him. "Oh, go on, you just wanted to grab it, admit it!"

	Their father hesitated.  He had felt a flash of anger at the touch.  It had felt wonderful and he HAD wanted to know what they were up to, but to be touched there so openly was out of place for a father and son! The kiss was also out of place.  So was the entire situation.  He wasn't sure if he was angry at Donatello or himself, though.  The anger had just been so sudden, even as he thought about it it changed to embarrassment.  He'd never had anyone grab him there before, not even Tang Shen.

	"No, do not be sorry.  I should not have yelled." Splinter forced a smile. "I really don't have any experience in any of this.  I think... I think you scared me when you did that."

	"Scared? From a handy?! Wow, Master, you really gotta get out more." Michelangelo laughed, then stuck out his tongue at the other three staring at him open mouthed. "What?"

	"Thank you, Captain Tact." Raphael shoved his brother off his stool into the water.

	"It is kind of embarrassing at first, Sensei." Donatello leaned back, though didn't move away beyond that. "You sort of get used to it though."

	Splinter looked down at his own erection  sticking up out of the water. "Yes.  I imagine so.  After so long without touch and without being allowed to let your guard down, things can get embarrassing indeed when you do.  That is not why I was scared, however.  I was scared because you are my son.  You are all my sons.  It is not normal or right to have a sexual relationship with you."

	Leonardo shrugged. "What relationship? He was just showing you how to kiss and maybe touching your dick.  You're not dating or anything."

	"Yeah, I don't want to have any sort of relationship with you beyond what we already have." Donatello leaned back in and wrapped his hand around his father's erection again. "You've taught us a lot.  Maybe this is something so we can teach you in return, as a show of gratitude.  There will be no relationship stuff, dating, marriage, or whatever else you'd want to call it involved, I promise.  Unless you guys want to."

	There was a chorus of variations of 'no way' and 'of course not' from his brothers.  Donatello didn't let go of their dad's cock throughout, but didn't stroke it, either.  Just holding it seemed to be enough with Splinter being silent.  It was very hot and alive in his hand.

	Splinter found it hard to think while the teen was touching him there.  His body wanted him to let it go and have fun.  Rigid discipline told him to stop the encounter.  They had already been doing it with each other for who knew how long and they seemed fine, however.  There had been no reduction in their efficiency or interruption of their teamwork in fighting the foot clan.  His son's touch was so warm, welcome, and invigorating.  Perhaps discipline could be ignored, just for a while.

	"Very well.  You are right.  It does not have to be a relationship." Splinter pat Donatello's wrist. "You may continue your lesson."

	Donetallo grinned. "Shouldn't you call me, sensei, Master Splinter?"

	"No."

	"Right you are, Sensei." Don was nervous there.  He knew he shouldn't have tried to be more like Michelangelo with the smart comment.  Thankfully their dad didn't seem upset by it despite the curt response. "So... you've really never had anybody hold you like this?" Donny pumped his hand up and down, rather enjoying the way Splinter sucked in a deep breath and tilted his head up in response. "or sort of rub like this?"

	"No again, unfortunately." Splinter ran his own hand along Donatello's arm. "Even doing something like this simple touch has been uncommon.  It feels very pleasant though, please continue.  I know the motions but not the experience of sharing it."

	Michelangelo climbed back onto his seat. "Er... anything you want us to teach you, Sensei? It's not as much fun to just watch."

	Still focused on Don's hand, Splinter didn't look over. "I think one at a time is best for everyone, Michelango."

	"Yeah, wait your turn.  Besides, you guys know I'm the best with a staff." The blank stares that got Donatello made him huff. "Staff... pole." He pumped his dad's shaft faster, making the old rat's legs stretch out in front of him for a second. "You know... POLE."

	There was a soft grunt with the faster speed and a less happy one a moment later. "No puns, Donatello.  I may not be experienced, but even I know those will kill the mood!"

	"Yes, Sensei... Anyway, wanna try kissing again during it? It's a lot more fun that way." At a nod, Donny leaned over, then bent down and kissed Splinter's cocktip.  The surprise on his father's face was worth it when he leaned back up to look. "Oh did you mean a normal kiss on the lips?"

	"I did... yes.  Though I can't say that was unwelcome.  Just very unexpected." Splinter squeezed both fists closed in embarrassment. "I would not have thought to do that."

	"How about I stick with more expected for now?" Donatello kept his hand moving, finding something new himself when his palm bumped his dad's balls during it, something that didn't happen with his brothers, with theirs inside their shells.

	He really needed to pay more attention to those later, but for now, he leaned in for another kiss face to face and enjoyed the eager lips meeting his beak.  Splinter looked into his eyes for much longer than his brothers would and they both felt it more intensely than Donny was otherwise used to.  Holding his dad's gaze felt so strange and intimate.  He closed his eyes to break the connection, not feeling quite as comfortable keeping eye contacted with it being Splinter he was sharing the kiss with.

	It really was different doing it with his father rather than his brothers.  With them it had just been fun goofing around as always.  With Splinter it felt like he was being judged for everything he was doing and what he was doing was giving the old rat a hand job and kiss.  He knew it wasn't something he should be doing with a parent, he was sure Splinter felt the same way, but he couldn't stop since he'd started it in the first place.  It would be humiliating to not be able to finish the job.  His brothers would never let him live it down and he doubted he would ever be able to look at his dad again.

	Similar thoughts were still running through Splinter's mind.  Donatello's hand felt lovely around his erection.  After so long alone, it felt better than being in Tang Shen had.  He knew that was not true, but the memory was from so long ago and the moment so brief that the pleasure of that moment had faded to almost nothing.  The living hand of another there and then was so much better and his son certainly knew how to move it.  Having tried masturbation a few times in the past himself he knew it was an awkward and embarrassing act.

	He couldn't imagine all his sons doing it so freely together and broke the kiss to ask. "You all rub each other so?"

	Donatello opened his mouth to speak, but Leonardo go there first. "Not all the time but, yeah, we do.  It's quick and easy."

	Raphael stood up. "Say, Sensei, why don't you give it a try? I got a sai you can try it out on."

	"Please quit calling it that, Raph." Donny sighed. "No puns, remember? And I think he should try it on me since I'm doing this first."

	"Hey, that isn't a pun. That's a euphemism." Raphael moved his stool next to Splinter's right side. "Besides, he's better right handed and you know how hard it is with your off hand." Raph ran a hand down his dad's right arm. "How about it? You can copy what Donny is doing.  I bet you'll be real good at it."

	"This is all going very fast, Raphael." Splinter looked at his face, then down at the erection jutting proudly up from his groin.

	All of the turtles were slightly better endowed than he was.  They had to be for it to get around the curve of their shell.  Raphael, like the others, had plenty to show and it certainly looked tempting swaying lightly above the water from the waves they were all making and from his own heartbeat.

	It was a little darker green than the rest of his skin and a mix between feral turtle and human in shape and girth.  Splinter's own shaft was a mix of rat and human, both in shape and girth, leaning more toward human in size than in rat.  He had never really considered that aspect important until appraising his son's shaft.  While he knew there was no shame in being smaller, he wondered how he would have felt if his had been significantly smaller and was glad he did not have to find out.

	Like most boys in the dojo, he had compared his to the others while human.  He had not been the biggest or the smallest and had been glad of that.  Those with the biggest had always been unpleasant and those with smallest had always been teased far too cruelly by others.  None of his sons had ever said anything about it despite bathing nude many times together.  He wondered if they had thought about it like he was thinking now.

	After staring longer than he should have and enjoying Donatello's attention, he grabbed it like Donny had grabbed his.  The thrill of doing something taboo hit just as hard as the embarrassment of knowing what he was doing.  Even at his age such things could still affect him as though he were a young teen himself again.

	"But I will try." Splinter squeezed hard out of curiosity and let go immediately when he saw the boy wince. "I assume that was too hard.  Should I be gentle like they say on television?"

	Raph caught his dad's wrist and held it lightly. "Erf... A bit lighter than that, Sensei, yeah."

	Donatello squeezed firmly once to show how a hard one felt and Splinter nodded as he spoke. "You don't have to squeeze hard, just hold it and move your hand." His wrist pumped slowly up and down. "Try to copy this.  It's really easy."

	Splinter copied the motion easily enough, but was still hesitant about it.  The flesh down there was similar to the rest on Raphael, but hotter.  Knowing what it was made everything about touching it different than anywhere he'd touched his son before.  He kept his eyes on it as he moved his hand for the most part, but did glance up into Raphael's face to give him a quick embarrassed smile.

	"The motion is easy, but I find it hard to keep going.  Part of me wants to let go and stop." Splinter pushed his hand forward experimentally to bend the teen's erection forward some then side to side. "I am not sure if I should be doing this, but it certainly doesn't feel bad, so much as very strange.  Is it alright when I move it, Raphael?"

	"Yes!" Raph coughed at the overly emphatic response.  His dad's hand felt so much different than his brothers' hands with a hint of fur tickling his skin and the claws occasionally poking as well.  Splinter was going to have to learn to keep those away, though they weren't hurting.  His hand was a lot hotter, too. "Just don't push too far, these things can break if you put too much pressure on them."

	"I said I was sorry.  Besides, it wasn't that bad.  You got it back up in a week." Leonardo looked embarrassed with cheeks flushed. 

	Mikey splash them both. "Hey, focus on master splinter, not that, dudes."

	"Thank you, Michelangelo." Splinter didn't look away from the cock in his hand.

	His sons were so relaxed and casual about their bodies.  He had never been so comfortable even when human.  True, he had been relaxed about nudity, but that was not touching or taking any active interest in any of the bodies around him, including his own.  Actually exploring the body of another was much more emotionally involved than just being around one.

	His heart was racing from Donatello's.  It was racing faster from holding Raphael.  Giving was always good, as was getting, but doing both was always best.  Focusing on both was the difficult part.  He was supposed to copy Donny, but the rhythm didn't feel right for the part of Raphael he was working with.  The size difference perhaps.  He wasn't sure, but he did his best and and a cleared throat and deep breath seemed to suggest it was appreciated.

	"That's pretty good, Sensei." Raphael leaned back into the warm water and let his shell float his torso instead of sitting. "Speed up.  Lets see if you can make some waves."

	"An interesting challenge." Splinter wondered if he should lie back to float as well, but doubted he could do that and still pleasure his son. "And what happens if I do?"

	"Then Donny will speed up, too.  Right, Don?"

	Donatello ran his thumb over the front of his dad's glans and sped up just a little. "Right.  Normally we'd all be involved.  I don't think you're ready for that, though."

	Their father nodded, both at the thumb touching a very sensitive spot that felt quite good and at not being ready for all four at once. "I think you are right.  Even just handling you two is difficult to concentrate on for now.  So many distractions."

	"Aw, we're going to have to just watch?" Michelangelo slapped at the water in disappointment. "That's such a bummer."

	Nobody even looked at him.  The others were all watching Splinter pumping his fist on Raph's cock and his responses to Don's attentions.  Even strokes up the eight inch shaft did indeed make ripples in the water and the faster he moved his hand the faster Raphael made them.  Splinter tried to go too fast and while he did make waves he also made the teen sink and splash.

	"Not quite as easy as that.  Gotta find a good middle ground, Sensei." Donatello sped up in time to what he could see of his father's hand, but it was hard to be exact.

	He was enjoying the time touching Splinter, especially the fleshy balls that bumped against his little finger each time he went down far enough.  They had all seen them, but none of them had ever really gotten to touch them before.  Splinter's fuzzy scrotum was the same light color as their dad's chin fur and stood out rather nicely against the darker fur of his thighs and the dark red of his dick.  Maybe it wouldn't be too much if he played with those, too.   The first to get to fondle them!

	Splinter adjusted his speed, trying to match the pace with Raphael's body floating back up after each down stroke.  It made the waves smaller but steadier without pushing him too far under.  He found it lovely to feel the flesh shifting with the motion, until he was distracted by Donatello squeezing and curiously tugging his balls.

	Not flinching at the touch took a great deal of effort.  Not looking took just as much effort.  He didn't want to seem surprised by that touch, but he was.  His scrotum and testicles were the obvious next step for his son and he should have known that Don would play with them.  The fact he hadn't expected it was embarrassing.  He should have known and looked forward to it! If only the hand on his dick and his on Raphael's hadn't been quite so distracting, even with as slow as they were going.

	Donatello wasn't in a hurry to get an orgasm.  He just wanted their father to enjoy the touch, a long hand job to get him used to it seemed just the thing.  Even Raphael wasn't trying to hurry it up for his own, though with Splinter clumsily pumping him, he could certainly feel it getting closer.

	"This isn't too much, is it, Master?" Donatello lifted Splinter's scrotum up and let it go to watch it and his balls inside shift in the water.  They were so different feeling from his dick.  So soft and exciting to a turtle who had never gotten to touch something like them before. "I can stop if you need me to."

	Raphael didn't see what Donny was doing, but he felt a change in his dad's stroking just a minute after it started.  The rat pulled his cock to the side more as if distracted and the pumping was less steady until they threatened to make him sink into the water too much again.  He leaned forward careful to try and see, but there wasn't much he could make out on his back as he was.

	Splinter had stopped looking at Raphael when he finally gave in to curiosity and had his eyes on Donatello's hands on his balls and dick.  He hadn't expected to enjoy it so much, even if the enjoyment wasn't as strong as he had expected.  They were sensitive enough, but compared to the hand working his erection, the touching of his sack was more like a kiss on the cheek.  It was more the feeling of his testicles being moved around inside that he was enjoying rather than the steadily building tingle in his groin from Donatello's continued attention to his cock.

	"No, I do not think that is too much, Donatello.  It is rather nice." Splinter stopped jerking Raphael. "I think it would be better with a kiss, however."

	Raph rocked forward back to an upright position and grabbed his father to kiss the moment he heard that. "I'm on it, Sensei!"

	"I think he was talking to me, Raphael." Donatello didn't complain beyond that, though, he had another idea and leaned down to kiss his dad's glistening tip again.

	Leaking pre-cum had given Splinter quite a shine down there and when Donny's lips pressed into down it stuck to and moistened them too.  The turtle's beak slid easily around the fleshy tip for for a series of quick kisses.  He couldn't resist slipping his tongue out to lick after the first few.

	Splinter pushed into the kiss with Raphael.  His growing need made him want more touch and having two sons holding and pleasuring him satisfied that perfectly, especially when Donatello moved to kissing as well as stroking.  He liked the licking tongue as much as the pumping hand.  He was a bit disappointed when the hand on his balls went still from Donatello focusing on other things, but Raph made up for that by rubbing over his chest.

	Watching the three of them, Leonardo and Michelangelo looked to each other.  Being left out wasn't much fun.  They'd put up with it long enough and seeing the escalation before them made them want to join in more.  Leonardo slipped off his stool and grabbed Mikey's erection.

	"Wanna share?"

	"Heck yeah, dude.  Sixty nine?"

	Leonardo paused with his mouth open just long enough before pushing his brother down and spinning him around to straddle him. "Sure!"

	It was more complicated mounting in the water than on land, but the two brothers had had plenty of practice before in the spa, well the onsen.  Being turtles they had no trouble floating or holding their breath as needed even with a dick in their mouths.  It only took about five seconds for them to work everything out and be floating together as they pleasured each other.

	Splinter didn't see them.  He was looking into Raphael's eyes and feeling happier than he had in years.  Long pent up urges were finally being satisfied, both for companionship and intimate physical contact.  Just being allowed to let down his stern shell was a wonderful thing in itself.  Even if he hadn't had all the other benefits with it, that would have been enough to make it a good night.

	The tingle in his loins had grown to a fire and after so long without any attention down there once it was lit he went off quick.  His hands grabbed Raphael's shell under his arms and held on tight.  His hips thrust forward into Donny's hand and pushed past the turtle's last kiss so his cock popped into his mouth.  His previously ignored tail curled forward around Donatello's legs and he came.

	Globs of semen squirted directly onto the roof of Don's mouth and all over his tongue.  Pulse after pulse pumped out and as they did, Donatello felt his father's balls pull up tight against his groin for the duration.  The amount that came out was impressive compared to how much he was used to from his brothers.

	The rapid shallow breathing told Raphael all he needed to know about what was going on.  He hadn't felt Splinter cum but he was sure he had with those signs and the grabbing.  It would have been so much better had he been able to cum with him.  There was a work around for that, though.

	Raph caught his dad's right hand and guided it down to his groin again, breaking the kiss just long enough to say. "You're not finished yet."

	Splinter was too lost in the pleasure to actually respond.  His hand did grasp the boy's dick and work it unsteadily but his eyes were unfocused and his jaw was slack.  The passion had been just as strong as when he had had his first and only time back in Japan and he still felt the afterglow fogging his mind several seconds after it actually finished.

	It took him another ten seconds or so to really come down enough to notice he was still stroking Raphael. When he did he felt embarrassed, both for giving the hand job at all and for not doing it while he was enjoying his orgasmic bliss.  Being a father pleasuring his son was still troubling him, but pausing in the middle for his own pleasure seemed rude.

	Splinter looked oddly shy as he apologized. "I am sorry, Raphael.  I did not mean to stop.  Your brother was very distracting."

	"Heh, yeah, he can be.  He has a way with his mouth." Raph felt embarrassed too, but only because he had never seen his dad that flustered before. "Hey, maybe you, uh... should try it yourself.  It's not hard.  I know, what don't..."

	Michelangelo quickly pulled his brother's dick out of his mouth. "Oh oh! I get to teach him that! I call dibs on training him to give a blowjob!" He shoved Leonardo off his dick and splashed over to flaunt it at their father. "Here, Sensei, give it a try!"

	"Mikey... " Raph clenched his fists at being interrupted and having the opportunity stolen from him. "Wait your TURN, Mikey."

	"What? You're already getting a turn. You know, teaching him to give you a handy.  Looks like you've got it well IN HAND!"

	Donatello coughed at the unexpected blast of cum coating the back of his throat and the roof of his mouth.  He wasn't sure how long his dad had been pent up, but there had certainly been a lot of it.  He'd counted ten strong jets of it squirting in and several weaker ones after it.  There had to have been three cubic centimeters worth in that rat's prostate and every bit of it had shot into his mouth.

	Swallowing it had been easy enough after having plenty of practice with his brothers, but it tasted a lot different and even had a different texture.  The other turtles had been thinner and more salty.  Splinter's had been much warmer and slimier on his tongue.  Donny could still feel it lingering there and down the back of his throat.  He liked it.

	After a couple more coughs, Donatello had cleared his throat enough. "Wow, Sensei.  That was a lot! And no puns, Mikey!"

	"Oh alright, I'll try." Michelangelo ran a hand down Splinter's chest. "So what about it, Sensei, you wanna try? Just look how happy Donny is after it.  That could be you."

	Splinter did look.  Donatello didn't look any happier than he had before, but he also didn't seem at all upset.  He looked closer and let a faint smile come back to his muzzle, actually, there was a bit of flush to Donatello's cheeks.  His son did look a little more content than before after all.  Maybe it wouldn't be too bad.  He could live with a bit more embarrassment doing things he shouldn't be doing.

	First, though, he had other things he needed to do. "I will try, Michelangelo, but I will finish Raphael before starting something new."

	"Raphael huffed and crossed his arms over his chest in annoyance. "I dunno, Sensei, I'm not sure I'm in the mood now."

	Splinter looked down at his son's cock for a few seconds, then back up to his face. "You are still stiff in my hand and I can feel your heartbeat racing through it.  My experience with love may be limited," he pumped his hand up and down again and kept going steadily faster, "but I think you are still in the mood to continue."

	A tug to the right from Splinter's hand holding Raphael's erection made the teen lean that way and a tug left did the same.  He may not have had a lot of experience but he was a quick learner.  It was surprisingly easy to read the boy's needs using just the one hand.  The faces Raphael made from his experimental tugs and jerks were cute, too.

	Raph noticed the difference, too, as he fidgeted with his hands going back to hanging by his side so he could watch. "You SURE you never did this before, master?"

	"Not even once." Splinter kept his hand moving, but varied the speed in time to his son's reactions.

	Tensing thighs suggested he liked faster much more than slower and he seemed to like it tugging to the left more than the right.  Raphael's already teased body didn't last too long with his father's full attention.  He'd been close before the action had stopped and the renewed play worked him back to the edge in only about a minute, in the mood or not.

	After barely a minute of rapid handling, Raph's hips thrust forward and he hunched over hard, mouth open eyes shut.  A strong spurt of white shot from his dick into the air and splattered his own face.  Splinter held on, knowing what was happening but amazed at how it actually felt to hold someone while it happened.  He felt every pulse up his son's erection before the white came out.  Some of it landed on Raphael's chest shell, some on his own arm and hand.  One blob landed just on his lower lip.

	Splinter licked it off without thinking and didn't taste much since there wasn't enough sticking there to really taste.  It was slightly slick but otherwise there wasn't much to it.  What he saw running down Raph's chest plate was runnier than he had expected.  Still, there was enough of it for him to curiously touch with a finger on his free hand and smear around while the teen just stood there panting.

	"How was that, Raphael?"

	"Well, I'd say that was pretty good, Sensei.  Heh, you're a fast learner."

	Michelangelo splashed his brother. "Yeah, like that's a hard skill to learn.  Hold on and wiggle your hand." The turtle turned to his father and pat his proudly jutting out erection in invitation. "I think you'll find using your mouth is much more complicated, Master Splinter.  Now that you're done with him, I'm ready to start your next lesson."

	"Yeah... so generous, Mikey." Leonardo sat back on his stool, moderately annoyed and feeling frustrated at being teased. "I was doing just fine."

	"You already know how, Leo.  This is to teach our dad, right? He needs some love."

	Donatello wiped his mouth off, having drooled a little of Splinter's cum from the initial unexpected volume.  He had swallowed most of it but kept just a little to swoosh around his tongue.  Leo and Raph had never been great fans of the taste or texture, but he had enjoyed it enough.  Holding it throughout Raphael's handjob had been easy, but it was getting diluted so he decided that was enough and swallowed the last of it.  Knowing what it was and watching what had happened had left him really horny himself.

	Don waved. "If you want some attention, Leo, I have two free hands and a mouth..."

	"Nah, I'm in the mood for something tighter than a mouth or hand right now.  Thanks though."

	Splinter was amazed at how casual his children were about sex.  The casual offer.  The casual dismissal just because he hadn't gotten something right away.  Even the casual flaunting in the guise of teaching.  Every one of those things made him feel uncomfortable.

	Looking at Michelangelo's offered penis was equally awkward.  Splinter was already satisfied with having had an orgasm already.  It had felt wonderful and relaxing, but he tried not to think of the actual act that had led to it.  Nudity was so much different from purposeful sexual contact.  He did WANT to try it, though.  Flesh and intimate contact with others may be embarrassing, but there was also an exhilarating thrill to it.

	Splinter swallow hard and steeled himself for it, he also didn't want to seem too shy to his sons. "Alright, Michelangelo.  How, er, should I start?"

	"How to... you just do it, dude." Mikey stood there for a few seconds, then moved closer to make it easier. "Since you're sitting on that stool in the pool you can just be cool and grab it to uh... fool uhm around? Sorry, I can't think of a good rhyme.  Just lean down and take it in your mouth." The turtle swung his hips to make his erection swing back and forth. "Of course you can just rub it on your face first, too.  That's always fun."

	Donatello frowned at Leonardo. "My hand isn't tight enough? Since when?"

	Leo sighed. "I kind of want a girl, Don."

	Donny smirked. "Well, I don't see you getting one tonight or probably tomorrow.  But hey, if you want my ass, just say so.  Unlike some I don't mind it a bit rough back there."

	The chatter was very distracting for Splinter.  With Mikey's dick in front of him and his own shyness to overcome, the distraction was welcome, though.  Maybe if he just closed his eyes he could do it without having to think about it, but then he wouldn't see it either.  As much as he didn't want to was as much as he did.  There was no reason to let himself be so shy.

	Splinter took a deep breath and tried to clear his mind.  He smiled up at Michelangelo, opened his mouth, then hesitated.  There was nothing wrong with sucking another man's dick, he was sure that was fine.  Mikey and Leo had already done it right in front of him.  Just doing it to his own son was still bothering him.  He didn't want to be a bad dad.  Then again, what was the harm? They did it all the time.  His head tilted down and forward, the turtle's hips pushed forward, and he felt the stiff flesh bump against his front incisor before sliding under it and touching his tongue.

	It was too late to stop now.  Splinter was glad of that.  Since it had happened, his racing mind couldn't weasel out of it.  All he needed to do was try his best.  That was all anyone could do.  He opened his mouth.

	Michelangelo pushed in without hesitation, unthinkingly shoving his whole cock in at once and then yelling in discomfort at the teeth scraping along it. "Ow! Hey!" The dick was quickly removed. "Woah, dude, Sensei, be careful! No teeth."

	Splinter looked up, licking his lips curiously at the texture that had been on his tongue and the surprising lack of flavor that went with it. "I didn't do anything other than hold my moth open, Michelangelo.  You did the rest."

	"Well... I'm not used to much teeth being there." Mikey rubbed his dick with his right hand. "Well, no damage.  How about we try again. This time, be careful and you can go down as slow as you like.  Uh, watch those front incisors."

	Leo clenched his beak watching the first blowjob attempt before snapping at his other brother. "I don't want your ass either, Don. I want a girl."

	Donny snorted at Leonardo. "You didn't want a girl when you offered to 69 Michelangelo.  I think you're just upset he ditched you for Master Splinter."

	"Maybe you're right." Leonardo hesitated then floated over to bump Donatello's groin with his beak. "Oh, Why not? Come on."

	Splinter looked over to them.  With no real teeth in the way, his sons would have an easier time with it.  Rats had much more to worry about in their mouths.  He had never really considered the two big gnawing teeth his rodent mutation had left him with.  They were useful for biting things, certainly.  Getting something into his mouth without biting it could be more tricky.

	After a little probing with his tongue to figure out what might work, Splinter opened his mouth and tried again.  Having already had it in his mouth once made it a bit easier to do.  The embarrassment was there, but manageable.  None of them were concerned about him pleasuring them and Michelangelo barely minded his teeth scraping him.  Why should he feel bad about it?

	He was glad his son was clean down there, too.  While he wasn't sure what he had expected Michelangelo's genitals to taste like, he was sure it would not be wonderful.  That son in particular seemed adverse to bathing at times.  Splinter tried to get his calm back once more.  His thoughts were wandering wildly.  His body was responding wildly too with his penis already swelling again despite the orgasm just a couple minutes ago.

	Mikey was watching him curiously.  His dad was definitely having trouble or something with what he was doing.  Splinter just sort of stared at his dick with his mouth open for an awkwardly long time.

	After ten seconds or so he had to ask. "Is everything ok, Master?"

	Splinter closed his mouth. "Yes.  I'm just thinking.  I can't see my own teeth so I need to work out how to approach this."

	He didn't want to admit anything else and doubted Michelangelo would understand if he had.  Instead he tried pushing in straight ahead but more off to the right.  After just the tip slid in he immediately felt his son's erection bump the teeth on the side of his jaw instead of the center teeth and stopped to try something else.  When he pulled his head away again, Mikey gently grabbed his head.

	"Maybe try angling so I go in at an angle."

	"You may be right.  That might slip between both sets of teeth." Splinter turned his head a few times again, then tried what he thought might be the best angle for that.

	He had his mouth open, then closed it when he realized he really didn't need to have it so wide.  His son was not even as wide as an apple, there was no reason to open all the way up.  Opening just wide enough to slip it between his jaws seemed like it would be sufficient.  It also let him feel the turtle's somewhat cool to the touch penis skin drag along his lips.

	Like Raphael's it was smooth, but by using his lips instead of his fingers he could feel little folds in the skin that allowed it to swell and deflate.  When his tongue brushed over it he felt it pull up in a clench.  It seemed just as sensitive to touch as his own and still tasted clean, though with it in his mouth longer there was a hint of sweat on it that he hadn't noticed before.  It felt nice enough, once he got past the embarrassment of what it was he was holding in his mouth and that he was staring at his son's groinal shell region.  He knew there was a term for that region, but with everything going on he couldn't think of it.

	Splinter looked up at Michelango while figuring out the movement.  Mikey was looked down at him with his usual smile and he had to look back down.  Eye contact while sucking a dick was too much even for his calm control.  With some practice, maybe he would get used to it but definitely not for the first time and definitely not while the others were watching on that first time.

	"You're doing fine, Master.  I haven't felt any teeth yet." His son's voice made the rat push the discomfort aside again and focus more, but otherwise there was no response other than a vague grunt from his father.

	Splinter pushed his muzzle forward slowly.  He'd never been so aware of his teeth before.  It was an odd thought and helped relax him a little.  Paying attention to teeth was such a silly thing, but it was needed for that.  Michelangelo had been right about the angle, but the teen's own length worked against him when his cocktip poked against the back side of Splinter's molars deep in his mouth.  Trying to turn his head to the side more pressed the shaft to his front incisors with barely enough room to push another inch in.

	He'd thought his muzzle was too long in the past, but it was really only about as long as his hand.  Any of his sons, from what he'd seen of them erect round him so far, was about as long as that between their legs or slightly longer.  Even if they did get past his teeth, the only way he could take all of them would be to have them shove the last inch or three down his throat.

	To his side Donatello and Leonardo were already showing him that such a thing as fully possible.  Donatello's mouth slid down Leo's erection just fine.  With his shorter beak he should have bottomed out long ago, but Donny easily held proportionally longer than Splinter did.

	Watching his dad, Michelangelo followed his gaze. "Yeah, dude, see? He can take it all pretty well.  Leonardo isn't so good at it though.  He can only take half of any of us in his mouth.  No worries though, it's good either way."

	Off to the side happily coming down, Raphael rubbed his spent dick. "Yeah, you don't have to go all the way.  You've got most of it from what I can see, Master."

	"I'm teaching him, Raph, you had your turn with teaching him how to give that hand job.  Seems like he did pretty well, too, heh, you didn't last long."

	Splinter tuned them out to focus on the new experience once he was told he didn't have to take it all.  He was glad to hear it.  The idea of anything poking down his throat didn't sound too fun, though Donatello seemed to enjoy it with how easily he had been doing exactly that.  Maybe he could make up for it with the motion instead.

	Even as inexperienced as he was, Splinter knew that just holding it there wasn't enough.  He had to move his head just like had to move his hand earlier.  Knowing it didn't make it easier, though.  The angle he had to hold and the unfamiliar motion even if it had just been straight in was strange feeling.  

	Splinter also wasn't sure what to do with his hands exactly.  He could rub Michelangelo's thighs but there was not much to rub other than that except shell.  Were they really sensitive enough to enjoy him rubbing their shells? His sons could certainly detect touch on them, but how sensitive was it in a pleasure sense? With his mouth full he couldn't even ask to find out what the teen wanted.

	Michelangelo was quiet for longer than he usually was.  Watching his dad holding his dick in his mouth was a weird thing to him too.  He'd never really fantasized about it, but there were other thoughts he had entertained in the past.  He really wanted to play with Splinter's balls for instance.  They would have to wait until later.  Until then, he tried to encourage his father by pulling his hips back and sliding his dick out just to see what the old rat would do.

	The sudden withdrawal confused Splinter at first and he leaned forward to keep it in.  A look up to Mikey didn't show much about what to do and he could only lean forward so far.  The moment he gave up following and let it slip out, though, Michelangelo thrust forward to push it back in.

	"Just follow the motion, Master.  You don't need to keep all of it in.  The tip is enough.  Oh, and if you sit up straighter, you'll probably be at the right height to just nod your head." Michelangelo looked happy with the advice.

	Raphael wasn't. "He means you can nod or bob your head up and down like you were doing with your hand for me, Sensei."

	"I was going to clear it up when he asked, Raph.  You had your chance, relax, it's my turn." Mikey pat their dad's head. "Try using your tongue, too.  Just lick all over it in there."

	Splinter couldn't resist the smile at the pat.  It felt good to be touched like that sometimes and being the father, he rarely had anybody do that.  He did sit up straighter, which meant he had to stop leaning forward.  His son had to move closer again with the new position, but Michelangelo had been right, it did make the motion easier.

	At first his Splinter had to keep shifting his head back and forth to keep his teeth angled safely.  As he got used to it though, it was fairly easy to push his muzzle down and back up with his head tilted just right.  He managed to speed up without too much trouble and found using his tongue to slide over Mikey's shaft rather nice at the same time.  While not sure exactly what all he should do with his tongue he found that flicking his son's tip on the way up each time made the turtle tense up.  It also earned him another pat on the head, which he liked.

	"You're doing well, Master.  Keep that up and I'll give you a treat!"

	"He's not a dog, Michelangelo." Raphael's body had recovered from his orgasm and he was stroking himself again to the sight of their dad going down on his brother.

	Donatello and Leonardo were doing the same to each other, with Leo gagging occasionally around Donny's dick going too deep and Donny having no trouble with Leonardo's.  They both paused to look at their dad on and off, but neither were in a hurry to finish.  For them, it was a pretty normal session, just with one additional partner in the group.

	After getting bored licking straight up and down his son's dick, Splinter tried coiling his tongue around it.  That got a more interesting effect for both of them.  He could touch more at once and enjoy dragging it over much more of Mikey's glans each time he pulled up high enough.  By the half grunts and thigh clenches it brought, coiling worked very well, too.  He wondered how it felt and thought about asking Leonardo if he would like to try.  Since Leo would have to be underwater for it, he decided against it.  Asking would also mean pulling all the way off and he didn't want that.  Sucking Michelangelo like that was more fun than he expected it to be, especially when he felt some slick fluid leaking into his mouth.

	Splinter knew it wasn't semen yet, but he had disturbingly little knowledge about sexual responses and anatomy.  Precum was effectively unknown to him.  While he knew he leaked a lot down there throughout his training in Japan, he had never looked into how or why.  His only brief encounter with Tang Shen had not been enlightening either.  The stuff coming from his son was mostly flavorless and thin, but did coat his tongue unevenly with a thin slick layer.  There wasn't enough to really get familiar with it.  Perhaps he could ask them about it later.  Whatever it was, Michelangelo was rubbing his head a lot more and even touching his ears.

	The ear touching brought a new blush to Splinter's cheeks.  Nobody ever touched his ears and having his son do it felt awkward, even more so while doing something already uncomfortably embarrassing for him.  He was almost glad when Michelangelo moved from touching them to pushing on the back of his head.  The push made it hard to pull off, but it kept the fingers from stroking his ears in a surprisingly pleasant way that he didn't want to explore just then.

	He hoped it was going alright after the push became more insistent.  Looking up didn't show much.  Splinter could only really see the shell in his new position.  His son wasn't giving any wasn't complaining so he had to be doing it right.  The substance leaking onto his tongue was still there and his hands on Michelangelo's legs were telling him the teen was very tense, which was how Raphael had been before he came.  Perhaps that treat he had mentioned was close to delivery.

	Splinter found that pulling his lips back some let him keep his sharp rodent teeth covered better so he could go faster as long as he was careful of his back teeth.  The effect on Michelangelo was nearly instant with that rapid bobbing bringing a sudden thrust from him.  Both hands on the back of his head pushed him down when Mikey thrust up and relaxed when he drew back again to do another.  Just four thrusts later, the cock in his mouth swelled just a bit and a strong jet of semen spattered into the roof of his mouth.

	"SHIT, SPLINTER!"

	Michelangelo didn't worry about being polite through the orgasm.  He loved the inexperienced mouth and hands rubbing him and it showed with how strong he came for his dad.  They were so much different from his brothers in pushing him to his peak and the exotic thrill of it had him giving the rat pulse after pulse of cum.  Normally he only got six to seven squirts.  Splinter brought out nine strong jets before he slumped and used his father as a support with both hands pushing on his dad's shoulders.

	For Splinter, it was a very interesting experience.  The texture was odd on his tongue and left a slimy sensation on it.  He wasn't sure if he should swallow it or not at first, though he hadn't seen his sons spit it out.  It wasn't exactly good tasting, but it wasn't bad either.  There was a definite muskiness to it and, disturbingly, some hint of pizza spices.  He really needed to get them to go easier on that stuff.

	His tongue sloshed it around his mouth a few seconds before swallowing it down and he didn't really think he liked the texture after he did.  It really coated his throat.  A thought strayed into his normally calm mind suggesting it might be good to take during a sore throat. He had to pull away quickly before he could laugh and covered it up with a cough.

	Michelangelo seemed happy with the cough. "Yeah, sometimes it does that when there's a lot.  A few coughs should have it out though, Sensei.  That was fun! Once your teeth were out of the way it was great.  You're mouth is hotter than theirs."

	Donny pulled his head off Leonardo's dick. "How much hotter, Mikey? It's definitely due to him being a mammal."

	Raph splashed him. "No puns and no science stuff, Donatello!"

	Sighing, Leonardo rubbed his still unspent cock.  He really wanted a girl down there, but right now he'd settle for pretty much any hole.  His eyes drifted to Splinter.  Their dad had gotten quite a good lesson on sex so far.  He'd had fun with both his hands and his mouth but he hadn't had fun with his ass yet.  Maybe that could be changed.

	"Um, Sensei.  There's one more thing to try..."

	Donatello waved a hand dismissively. "Actually there are several things left to try, Leo.  We could..."

	"ONE MORE THING TO TRY," Leonardo went on speaking louder to drown his brother out, "and I would really like to show it to you."

	Splinter hesitated.  As inexperienced as he was in love, he was quite certain what his son was going to suggest.  He had used his hands.  He had used his mouth.  He had received both as well.  As much as Donatello had suggested there were other things, there really was only one other major thing to try and he wasn't sure if he should or not.

	After a moment, Splinter swallowed again, coughed again, and smiled as confidently as he could. "And what might that be, Leonardo?"

	The turtle stood up in the onsen, erection stiff, needy, and throbbing, and moved next to and behind Splinter.  Michelangelo moved out of the way to give him room and his other brothers just watched, wondering how Leo was going to approach the subject.  As brave as they'd been so far, none had been sure how to get under their dad's tail.

	"Please stand up, Sensei." Leonardo just crouched in the water behind Splinter after the rat did as he asked and slipped his fingers down under their father's long fleshy tail. "Back here." One finger sank into the crease and felt around until it could circle the hole hidden down there. "Specifically right here." After a few seconds of rubbing with their dad standing very still, looking not at all relaxed, Leo stood up too. "With this."

	Splinter looked back at feeling the teen's plastron pressing to his back, then turned his head to stare straight ahead when his son's erection poked under his tail where the finger had been. "Ah... I do not know if we should.  It is not a thing a father should do with his son."

	Not something to do with something that feels so big especially.  With it touching his hole back there, it seemed much bigger than it had looked.  There was a thrill with that touch, though.  Clearly his sons had already done it with each other back there numerous times, but could he handle sharing that with them? The turtle dick pressed more firmly against his ring impatient to be inside him and he shivered.

	"I am not sure if it is right, Leonardo." Splinter pushed back just a little to feel more pressure pushing against his butt. "but I am open to being persuaded."

	Leonardo moved his hips back a little when his dad pushed onto him.  While he knew better than to try anything without lubricant, Splinter might not.  Going in dry wasn't good for either of them and water from the onsen wasn't going to be good enough for it.  Even if it were, he had to persuade his dad to let him first.

	"Not quite yet, Sensei.  As much as I would really like to persuade you, there's something we need to do first." Leonardo coughed and looked away, despite already only looking at the back of his dad's head. "We need to get slick."

	Splinter looked back and frowned. "What do you mean by slick?"

	"Lubricated.  You know... can't push a... I don't actually have a good metaphor for this."

	Donatello splashed them. "Like a piston in an engine. It needs grease to go though smoothly."

	"I am not quite so familiar with engines, Donatello." Splinter nodded though. "But I think I understand the reference.  This has to do with... pushing this," he grabbed his son's erection behind him, "into me then?"

	Leo looked relieved. "Yeah.  If it isn't all wet and slippery it isn't going to be fun for either of us.  Oh, like rug burn!"

	"My fur is not THAT rough, Leonardo!"

	"No, no, not your fur.  I mean... your flesh.  Um, your, uh..."

	Michelangelo laughed. "Your butt, sensei.  That hole you keep hidden under your tail.  Gotta grease that bad boy up so he can go to pound town!" All four pairs of eyes looked at him and he just looked back. "What? It's true."

	Splinter pushed his rump back gently while pulling Leonardo's erection forward to press against his sphincter.  There was very definite resistance.  There was also a lot of embarrassment.  He was not used to anybody talking about his intimate anatomy, let alone THAT part of it.  His penis was at least meant to be touched and enjoyed, his ass was not, at least as far as he had ever considered.

	Curiosity fought the embarrassment and won, though. "Alright.  What do you need to use for lubricant? I don't think I have any on me."

	Raphael hesitated, then stood up. "Well, we do have something for that." He swallowed hard and looked at his brothers, who either shrugged or nodded. "I guess I can get it out."

	Splinter was surprised to see embarrassment.  His sons had been blatantly touching each other and him with almost no consideration for how it might look to others, but suddenly they were embarrassed about... whatever it was they were embarrassed about? He chose to say nothing, but did squeeze his hand tighter around Leonardo's cock.

	"Oh! Sensei, that's a bit tight there! Is something wrong?"

	"I'm not sure yet." The old rat did not let go. "Continue, Raphael."

	The other turtle waded over to one of the decorative rocks near the middle of the onsen and unscrewed the top.  A quick dip of his hand and he produced a good sized clear bottle that was only about a quarter full.  Swallowing, he walked back and shyly offered it to Splinter.

	"Sorry... I know this place means a lot to you." Raphael didn't meet his dad's eyes. "We didn't really mean to uh, do things in here so much, but it was really convenient."

	Watching curiously, Splinter wondered exactly why that was embarrassing.  The onsen did mean a lot to him, though.  Were they worried about somehow spoiling or tainting it?

	He hid his confusion as best he could. "Thank you, Raphael.  It is good to know.  You aren't hiding any other things I should know about in here are you?" A flick of the teen's eyes to another rock told him they were indeed hiding other things, but Splinter decided not to worry about that.  There were already too many things to consider, such as how exactly to apply the lubricant.  He let go of Leonardo's stiff dick and turned to hand him the bottle. "I believe you wanted this, Leonardo."

	"Yes, Master! I hope it's ok if we leave it here when we're done." Leo popped the cap and squirted some onto his hand. "If we leave it in our room then things tend to get really busy in there and we can't get anything done."

	After turning to watch his son slick up his hand, Splinter couldn't resist asking. "How exactly do you apply it?" Leonardo showed his slick hand and rubbed his dick without a word. "You could have offered to let me do that... and you will." He held out a hand. "Slick me up, as you say."

	"Well, I can't say no to THAT." Leonardo squirted some onto his dad's hand.

	His dad lifted his hand up, squished the slippery slimy feeling goo around and looked concerned. "What IS this stuff?"

	Donatello sighed as though he'd had the conversation before. "It's complicated.  It's water based though, so it's non-toxic and will just dissolve in the spa, onsen, I mean onsen.  I could go into how it works if you REALLY want, but it's easier just to say magic." He stuck his tongue out at Raph. "That way I won't ruin the mood with science stuff."

	Splinter understood some of that and had an idea about it, but it really did feel very strange on his fur, under his claws, and all over his fingers.  Strands formed between his fingers when he squished it again and spread them wide, but it really did feel good, if chilly.  After giving it a sniff and finding no real scent for it, the old rat grabbed his son's erection and smiled at how different it felt with that stuff on his fingers.  So smooth.

	Leonardo grunted at the touch.  As always the lubricant was cold at first, but the heat from his father's warm blooded hand really was nice.  He hadn't noticed it when Splinter had squeezed him so hard a minute ago, but Michelangelo hadn't been wrong about how much hotter their father's body was.  It was a really nice change compared to his brothers. 

	Splinter also liked it.  He could feel the teen's penis features still, the subtle veins under his skin, the wide tip, and otherwise mostly smooth shaft, but pressing along them was almost like sliding his fingers on ice with how slick it was.  It was easy to see how much easier it would be to insert something like that into his... into down there.

	He hadn't noticed how big his son was in comparison to how small his anus had felt when the boy had poked against it earlier.  Holding that shaft again and considering the size in the context of it going inside him, the thing seemed far too big.  His tail pressed down firmly over his small hole in concern.  It had sounded so good in the heat of the moment, but with a little time to cool off and prepare, he wasn't sure if it was a good idea after all.

	On the other hand, according to his sons, they all had each other inside their rumps regularly.  Splinter looked at his sons again, they were each smaller than he was.  Surely if they could do it he could do it.  He took a deep breath and tried to relax.

	His heart beat was pounding in his ears, but he managed to calm down enough to regain control of himself and smile more confidently than he felt. "Alright, you may continue."

	Leonardo moved back around his dad, then dipped his hand under the rat's tail, or tried to. "Er, Sensei? I kind of need to get under this.  Can you lift it up for me like earlier?"

	"Yes." Splinter lifted the tip and last foot of his tail, but the actual root remained clamped down.  He concentrated on relaxing more despite his embarrassment and worry.  His tail shifted a little but he had to realize he was actually scared of having that thing poke under it and let go of that fear before it finally lifted all the way up and off to the side. "There, better?"

	"I think so.  You sure this is ok?" Leo slipped his fingers under and circle two around his father's tight fleshy ring.

	That it took Splinter almost twenty seconds to lift his tail told all of the turtles that he was worried.  Usually he had much better control of his body.  The only time they had seen him tense enough to have trouble controlling himself was when they were in danger in a life or death style situation.  They all remembered the embarrassment and uncertainty that had been there for their first times, but they had not expected somebody as calm and collected as Splinter to feel that too.

	"Yes.  I am sure it is ok.  You may continue." Splinter took another deep breath and used his own body as a distraction from feeling his son's fingers touching such a rarely touched or even thought of part of him.

	Rubbing his lube slicked hand along his own penis and balls let him not think of the growing pressure poking into his ass and spreading it open.  Just one finger pushing in felt like too much.  There was a dull ache from the unexpected entry when Leonardo's fingertip popped in suddenly and his sphincter clamped down HARD around it.  The slippery stuff kept it from hurting, though, despite that slight ache.  After a few seconds he didn't even feel the discomfort, just a general unusual fullness inside.

	Splinter gave his erection a few strokes. "This stuff certainly makes touching even myself feel different."

	"Yeah, it'll do that." Leonardo didn't look away from his father's butt.

	He liked the fur and well toned buttocks and thighs.  The rat tail was a rather attractive decoration above them.  It was also nice not having a shell to work around like he normally would with his brothers.  A quick glance at the three of them showed he and Splinter had their full attention.  They weren't even pleasuring themselves.  All three wanted to see how their dad reacted to having his ass worked over.

	Distracting himself only worked for a few seconds for Splinter.  His body demanded attention once Leonardo's finger moved some after it entered.  It was as exciting as it was embarrassing to have it inside and he couldn't resist clenching repeatedly around the finger once the initial reflexive clench had relaxed.

	Splinter looked down at his erection.  His sons had touched him pretty much everywhere while little and the remainder of the places just a few minutes ago, at least everywhere on the outside.  Being touched on the inside was much different.  He wondered if it felt like that for Tang Shen.  Probably not quite, since he hadn't put it in the same hole, but he had touched her inside.

	The finger in him pulled out suddenly and he tensed again when it just as suddenly pushed back in. "Again?"

	"Well, yeah, I need to move it in and out a few times until you relax around it, Master.  Also it helps to spread the lubricant around better." Leonardo cupped his dad's balls with his free hand where they just touched the water. "It's fun watching these pull up each time you tense up, though.  I never really noticed these when we were little."

	Fighting with himself to relax, Splinter looked back. "I didn't hide anything, you were just too young to worry about bodies.  We all bathed together just like we are doing now." He closed his eyes at a second finger probing his still tight anal ring. "On second thought, not at all like we are doing now, just as we used to do it last week."

	Michelangelo scooted toward Leonardo. "Yeah, I never noticed them either.  Hey, Sensei? Could you lift your leg up, I wouldn't mind a better look down there from back here."

	"Quit distracting us, Mikey, I don't want to go soft because it takes too long." Leo didn't say it too angrily.  Their dad's ass actually did relax and loosen up a bit with the more blunt talk.  Maybe Mikey's idiocy had its uses or maybe talking in general was helping him relax.  Either way, he surprised the rat when his second finger slipped in without much discomfort. "Oh, getting there, Master! Two fingers in is just enough.  Now if you can keep from clamping down on them quite so hard..."

	Splinter ignored Michelangelo's request and took a long slow breath as he would to meditate.  He really did want to try anal sex now.  With all that he'd already done it sounded like a good way to end it all.  One last act to explore with his sons.  One last embarrassing thing to not have to worry about trying later.  Get it over with so he could understand just why they were apparently doing it so much.

	"I think I am as relaxed back there as I am going to manage right now.  I admit I am as concerned as I am curious about what comes next." He turned to look at Michelangelo. "Maybe later."

	Leonardo pumped both fingers in faster and felt his father's interior clench rapidly. "Are you sure? It's not bad to go slow."

	"I am not sure, but I will say I am for now."

	"Well, alright." The turtle stood up, added more lubricant to his erection with his slicked hand, and scooted in close.  Just like before, his cocktip poked against the fleshy dark ring.  It was still hot and pulsing with his heartbeat.  His cheek pressed to his dad's muscular right arm and both hands gripped the rat's waist.  After holding still for about five seconds, he opened his mouth to speak and pushed forward before he was halfway through saying, "Here it goes."

	It wasn't a hard thrust, but it was enough.  His dick slipped in through Splinter's not quite ready but very willing ass hole.  By not waiting to give the warning he hadn't given his father time to tense up and Leonardo was glad he didn't.  Just as he finished saying it and just as he finished slipping the first inch inside Splinter bore down hard around him.  He probably would have clenched even if the turtle hadn't pushed in just from the expectation of it happening.

	Splinter let out a loud grunt, then tried to pull forward.  Only Leonardo's hands holding his hips kept him from popping his cock out.  His dad stopped pulling away once he realized it really wasn't hurting more than a slight sudden ache and Leo didn't push any more than that first inch inside, even if he wanted to bury his whole length in there.

	After several seconds of holding just the tip in, Leonardo kissed his father's smooth furred neck from behind. "You ok, Sensei?"

	"I think so." Splinter was silent for a few seconds. "It is very different from having your finger inside.  I assume that is not all you insert, however."

	"Oh no.  I'm just letting you get used to it." The turtle pulled his tip entirely out and enjoyed hearing the grunt from his father at the unexpected direction.  He also liked the huff that came after it when he pushed it right back in. "Like this.  See, that went in much easier."

	Donatello was impressed. "Way to go, Master.  You didn't tense back up like I did on my first time."

	"We all did, Don." Raph looked embarrassed. "Some more than others."

	Michelangelo nodded. "Yeah, Raph, you took almost twenty minutes to let me in."

	"I must admit, it is easy to see why you were all so unsure about it." Splinter thrust forward to experimentally pull out himself.  He pushed back on and closed his eyes at feeling his son penetrate him again. "It is certainly unique." There was another few seconds of quiet before he looked up, hesitated, and looked embarrassed again. "You feel very big inside me, Leonardo, however I think I could feel more."

	"Oh, you got it!" Leo pulled out again and thrust in further.

	He went slow, only poking in another half inch, then pulling back and pushing in a half inch past that.  All his brothers had gotten very good at judging how much they inserted during their early days of experimentation.  At first they had bragged about how much they could each take over a small amount of time, but soon they could all take it right up.  Splinter wasn't there yet.  He looked very uncomfortable at two inches and the sudden powerful grip around Leonardo's shaft told him that was enough for the moment.

	"Erg, that really is rather large, isn't it?" Splinter's tail swished in the water and his hands clenched reflexively.  He was very aware of his erection throbbing in the air, harder than he remembered it being even when being played with by his other sons. "I feel like I have to do something very private right now."

	Raphael smirked. "Yeah, that'll happen too.  You don't have to, it's just from being full like that."

	"I'm sure he knew that already, Raph." Mikey laughed.

	Splinter frowned, losing some of the excitement. "That's enough.  You three be silent now.  It's embarrassing enough without the comments and I want to concentrate!"

	They all went silent at that.  It was rare to see him get emotional enough to snap at them for talking.  When it happened, it was best to do as told.  All four turtles could understand the reaction since they still remembered their first days and the embarrassment it brought.

	Leonardo ran his hands over his dad's chest, enjoying the difference of the furry body versus hard shell. "Can I still talk, Master?"

	His dad caught his wrists and held them, but didn't push them away. "Yes.  Is it supposed to make my heart race when you push in?"

	"Probably." The turtle tried rubbing his beak against Splinter's ears, but they were too high to easily get to.

	Their father really was rather tall.  It was easy to see that when he was standing behind him with his dick inside. The only reason he could get that in was because Splinter was leaning and squatting some to let him.  He really hadn't realized it until trying to nuzzle that ear.

	Leonardo kept rubbing since his hands weren't being removed. "Does it feel bad?" He pulled out again and slid back in, deeper again. "Or should I keep going?"

	"Erk, er, try to keep going." Splinter had to hold his son's wrist.

	If he didn't, he would have grabbed his penis and toyed with it in ways he didn't want to.  Doing it himself had never seemed right or been something he wanted.  He could have asked any of his other sons to do it, but the thought of doing that also sounded wrong, very wrong, even if one of his sons was doing something much more intimate than that already.

	Again Leonardo slid out and back in, but he was more forceful.  The pounding throb from Splinter's racing heart and increased blood pressure came back stronger with it.  His breathing was shallow and rapid from anticipation and excitement.  Every thrust in took a little longer and left him feeling fuller.  He had no idea how much Leonardo had pushed into him or even how long it had been going before he suddenly felt the teen's plastron press against his buttocks.  All inside.

	"This is it, then, Leonardo?" Splinter clenched around  the boy's dick.  It felt very strange, uncomfortable yet satisfying at the same time. "You are all the way inside me?"

	"Yes?" His son was expecting more of a response from having him fully inside.  The question made him pull out and thrust in harder to make sure he was doing it right still.  His shell slapped against Splinter's ass with a wet splat and he saw and felt his dad's body bounce from it. "Everything ok, Sensei? You're very quiet now."

	Splinter jerked his up up to look at the ceiling at the harder thrust, then hung it down again, staring at the water.  He couldn't feel the exact details of his son's erection inside him, but it felt big enough inside that he was sure he should have been able to.  His tight ring could feel a lot of the shaft as it slid out and back in and there was an interesting bump at the tip with it.  There was a feeling of emptiness at the withdrawal and returning fullness again after that.  His balls jiggled, his tail shifted in the water, and he smiled.

	"I am just... focusing on what I am feeling, Leonardo.  Please continue."

	"You like this position, Sensei? You're kind of slouched.  Maybe it would be easier if you got onto all fours.  The water should be shallow enough for you since it is for us."

	"All fours is a very undignified position."

	"Yeah, but it's a lot of fun."

	Splinter looked back, just enough to see the turtle out of the corner of his eye, then dropped down onto all fours as suggested.  It really was an undignified position, but it was more comfortable and his son's cock sank in just a bit deeper with the better access.  Leonard grabbed his hips and jerked out and thrust in again, then again, and built up to a steady rhythm.

	The teen leaned over briefly to speak. "Let me know if I go too fast or need to stop, ok?"

	"Ung, you are doing fine... for now." It was oddly hard to concentrate on speaking with somebody plapping against his butt back there.

	The rocking was unexpected but fun.  It started off slow with Leonardo's pace and kept up with it until Splinter found himself nodding from the motion.  His ass gripped around the boy's cock while the water under him sort of tugged at his own half submerged in it.

	"Is there, unf, anything I should be doing?"

	The pace slowed behind him. "You can push back, though you're already sort of doing that."

	"I am?" Splinter paid more attention to his body.  The rocking was pushing him and of course he was rocking back the way he came.  He hadn't even realized that.  Of course he could push back harder.  Maybe as hard as his son had thrust into him earlier. "How's this?"

	Leonardo let out a long grunt at his dad shoving back into his thrust. "Better! Try to time it so I'm just going in when you do that.  Just try to follow the rhythm."

	His brothers watched jealously yet silently nearby as the two got into it more.  Splinter did as he was told, trying to rock back into their brother's needy thrusts and steadily got the hang of it.  The motions weren't hard, but keeping the angle right, keeping his rump relaxed but responsive, and just enjoying the situation took some time for him.

	Splinter's inexperience didn't slow Leo's pleasure at all.  The crude pushing and regular clenching around his cock was a wonderful thing for him.  He wasn't in the mood for a long slow fucking.  He'd been building all day, all day before that, and was ready to finish.  An inexperienced lover was just as good as an experienced one for him and the novelty of his dad's soft fur and hot body heating his dick was wonderful.  The soft bump of his balls against the top of his his inner thighs was even more fun.  His brothers didn't have anything to compete with that and his right hand drifted down Splinter's well toned buttocks to cup them.

	"I can't believe... we never really noticed these before.  Do you, ung... mind if a rub them?"

	Splinter liked the touch down there as much as his son did.  He'd never really had them played with before today.  There wasn't a lot to it like there was with having his dick stroked, but it was still pleasant and went well with the cock plowing into his butt.  Maybe he should have tried something like this sooner, he thought.  Leonardo felt very good inside and there was a subtle tickle in the root of his cock that grew each time the teen thrust in just right.  After several thrusts, that tickle slid along his erection until a bead of semen floated out of his tip in the water.  He found himself wishing he knew anatomy better.

	"If you keep pushing in at this angle, you can.  Something feels very good when errrg, you shove in right there."

	"Yeah, that's a special spot... we found, too.  It's great." Leonardo sucked in a deep breath to calm down and both saw and ignored Donatello's suddenly perky 'I know what it is and want to tell you!' posture.  He had more important things to worry about with the pleasure building in his own loins.  The happy tingle of pleasure from casual sex turned to a wonderful urgent itch he had to scratch.  His thrusts grew more wild and rapid with the impending orgasm. "If I weren't so close, I could... focus on just that... spot!"

	"You are talking very strangely." Splinter turned look back.

	He could just see his son behind him, grimacing and looking very strained.  After a moment, the memory of his night with Tang Shen surfaced in his mind and the tension he'd felt at the end.  A smile spread across his muzzle and he turned back to look at his other sons briefly.  Of course, they had all had similar tension when they'd been about to orgasm, too.  They were all watching closely and stroking themselves.

	Leonardo's thrusting in was fiercer than before.  Loud slaps of his shell against Splinter's muscular furry buttocks echoed around the room.  Waves spread out and grew higher around them with Leonardo pushing the water aside faster, harder, as he came to the edge.  It did feel good inside for Splinter, too, but he was not quite close to orgasm himself.  He still had full control of his body for his smooth rocking back into his son's unsteady pounding.  With the pleasure very slowly growing in his own loins, he experimented with another hard clench around the teen's cock as it drove in.

	A loud groan followed it and he relaxed quickly, only to do it again when Leo thrust back in again, mostly against that good spot in his dad's ass.  The turtle's still held his balls, but there was no rubbing them.  They squeezed tight and tugged a bit in time to his hips moving, but not painfully.  His son was holding back his orgasm for whatever reason, but only just.  It made him last another fifteen or so seconds, but it seemed like a lot longer for them both.

	Splinter felt the teen lose control and was surprised by how much he could feel when Leonardo came inside him.  The fullness of that cock spreading him open grew with the slight swelling of ejaculation.  The pulse of semen traveling along and spurting into him.  Even the pressure of that squirt hitting his inner muscle.  They were such small things but he felt and enjoyed them all clearly.

	Leonardo slumped over him after eight good jets of cum sprayed in.  His grip around Splinter's balls relaxed and he let go to run his hand over his dad's toned belly, legs, and groin instead.  His hand stopped roaming when it found the rat's erection.  He held it tight and tugged.

	"That was great, Sensei.  Thank you for letting me back here."

	Splinter squeezed his thighs together at the hand. "A little lighter grip, please, Leonardo, but you are welcome.  That was very nice.  Though I am not sure I am finished quite yet."

	Before Leonardo could even loosen his grip, Raphael stood up, but was shoved down by a much faster Donatello, who practically jumped out of the water as he stood up and splashed over. "I got this! This time it's MINE!" He dove into the onsen's shallow water, turned over onto his back, and spread his legs to expose his erection and the hole in his shell below it. "Now that you've tried receiving, Master, how about you try giving? I would love to have you in me just like he was in you."

	"I'm not done, Don!" Leonardo was winded and sounded out of breath as he protested.

	Even as he said it both he and Splinter could feel his erection deflating and sliding out.  Splinter  was pretty sure that Leonardo was finished.  He slowly raised up to kneeling.

	"You have had your turn.  I think it is my turn now."

	Donatello was too looked down to their dad's erection, full and ready. "Yeah, you are so done, but I'll be nice.  How about you slather him up for me, Leonardo? I want to feel you inside me, Sensei. I have got to feel how hot you are."

	His brother surprised him by not even protesting.  A quick squirt once he found the bottle and his hand was all over Splinter's erection.  He rubbed a bit faster than he needed, until his wrist was caught and pulled away by their father.

	"That is enough.  I'm sure it's slick enough." Splinter pulled Leo's arm to the side until the teen followed it away from him and then turned back to Donatello.  His techy son paddled close, but he did nothing for a few seconds. "I am not sure how to start."

	"Just, you know, push in." Donatello stuffed two fingers on his right hand into his own butt and spread them and the ring open about an inch. "You don't have to go as slow as Leonardo did, I'm pretty ready as it is, Master."

	Putting both hands on Donatello's shell just above his hips, Splinter didn't question it.  Still kneeling, he awkwardly positioned his hips until his cocktip touched the boy's hole and pushed forward.  Donatello's ass let him in easily, but gripped hard around him the instant his dad's hips touched his buttocks.

	Splinter grunted at the sudden grip all around his shaft and Donatello took a long deep breath at the rat's hot dick warming his ass.  Both were happy with their first time together.  Splinter really was much warmer than his usual partners for Donatello and Donny's butt was much different than his mouth had been and much nicer than Leonardo's hand.

	Donatello ran both hands over his father's chest and bell. "You feel really good in there.  When you're ready, just yank most of the way out and put it back in again.  That's all you really need to do."

	"Yes... I think I understand that.  I am not sure I'm ready just yet." Splinter smiled at the touch and brought his own hands up to rub his son's. "That chest petting is nice.  I don't think I've had anyone do that since I was very young."

	"Any time you want more I'm sure any of us would be happy to do it.  We never really get to pet your fur.  It's soft and smooth." Donny looked down at his needy erection, hesitated, then wrapped his legs around Splinter's hips to try and pull him deeper. "I wouldn't mind a bit more moving down there in return though."

	"Oh, yes.  Sorry, I got distracted." There was a hint of blush making Splinter's cheek fur slightly lighter color.

	He knew what was desired and he felt Donatello's inner muscles doing very nice things to his dick inside it, but exactly what he was doing was still getting to him, especially with his son being so open about petting him while practically begging for sex.  Out of all he'd done with all of them already, he hadn't expected that sticking it in would be the most embarrassing.  How was it more awkward than sucking Michelangelo's cock? Was it just the sort of position of power over Donatello on his back spread wide and inviting? The petting certainly made it more intimate, which could make it more embarrassing, despite how pleasant it was.

	After a few seconds of just looking down, Splinter realized Donatello was tapping his butt with his heels. "Sorry, Donatello.  I was just thinking of something.  Now, you said to do this, right?"

	He jerked his hips all the way out, more from nervous excitement than actually wanting to fully slip out, and thrust right back in again full length, then again.  Remembering how Leonardo had just kept going, Splinter kept going also.  Unlike Leonardo, though, he had difficulty finding a good rhythm.  Since Donatello had said not to go slow, he went as fast as he could.

	"Erm, Sensei? It isn't just about speed." Donny rocked with the rapid pounding. "Not that it isn't about speed, too, but it's better if you find a good rhythm that's comfortable for you." He didn't take his eyes off his dad as the rat kept going too fast and trying to make it work. "It does feel nice and you do look cute just going at it like that though."

	Splinter's years of discipline and exercise gave him great control of his body.  Even as fast as he was thrusting into Donatello's ass, his hips kept a straight motion with hardly any side to side.  Don wasn't sure if that was good or not, though. He liked some grinding going in and random slipping and sliding inside, at least he thought so until he found his dad bumping his prostate time after time going in.  With the steady angle, he was always drilling that wonderful spot.

	Maybe it wasn't that Splinter was bad at it.  Maybe it was he was good at it and the others were doing it wrong.  The rhythm was pretty good and there was more than enough lubricant to keep it slick.

	Splinter just looked down at him, concentrating far more on keeping his body aligned and steady than on actually enjoying what he was doing or how Donny was taking it. "It does feel nice, yes.  Though I am not used to being called cute by my own son.  I am not sure how I feel about that."

	Donatello ignored the last part as he rocked in the water under him, enjoying the intense focus on his dad's muzzle as the big rat thrust into him.  After a few firm playful squeezes around Splinter's cock, he tried to match the rhythm with his inner "hand." The rapid pounding made it difficult to catch and squeeze in time but each attempt felt good for both of them and was a lot more fun than just laying there passively taking it.

	Going so fast had been a way for Splinter to hide his embarrassment at first.  The concentration needed to keep his hips moving kept his face looking in control and make sure he had to hold onto Donny's shell tight to keep his hands busy.  A side benefit was that it felt very good.  On the less good side it was rapidly feeling too good.

	Splinter forced himself to slow down before he accidentally finished too quickly. "I think... I think I like giving more than taking."

	Donatello relaxed more himself at the slight speed reduction, also worried about finishing too soon. "Why, Sensei? Was something wrong with Leonardo back there?"

	It took Splinter several seconds to figure out what to say. "No, not exactly.  It did feel good, it just didn't feel like the kind of good that I could, er, finish from."

	"Aw, that's too bad.  I can finish from this just fine and if you keep going, nice and steady like this, I'm going to." Donny thrust his hips up to make his erection bounce and grasped his father's wrists. "No hands needed down there." He let himself rock in the water for another few thrusts, eyes closed just letting his body feel his dad's thick dick slipping in and out of him each thrust. "Not that it wouldn't be just as much fun with touching it, but sometimes it's just nice to have my hands free to touch a partner... especially if that partner is leaning over me ready for a kiss and nuzzle instead of focusing on myself."

	"Oh.  Should I lean over you then, my son?" Splinter looked at his other three sons, then back down at the teen he was fucking. "I know I've had all of you touching me in one way or another but this is still very awkward for me.  I'm not used to...MMF."

	He hadn't expected Donatello to suddenly leaned up and pull him down into kissing range.  His hands gripped the boy's shell harder for a second, then relaxed and let himself lean down further into it.  They held the kiss for several seconds before Don's beak dropped away from his muzzle and smiled up at him.

	"Any less awkward, Sensei?"

	"Not really, but it was a good try." Splinter stayed bent over him not quite touching chest to shell, hips rutting forward still making waves. "Thank you."

	Donny ran both hands down his dad's neck and over his firm chest.  He could feel Splinter's heart racing under his fur and skin as well as hear the handsome rat's shallow rapid breathing.  His own body was showing those same signs.

	"You're getting close, aren't you?" Donatello gently pushed his lover's chest away. "I am too.  Really close.  Look at my dick, Master.  I'm dribbling just from your cock stuffing up my ass.  Wow, I never thought I'd say THAT to YOU."

	Standing straighter again, Splinter did look.  His son's dick really was leaking a fair bit of precum.  Each time Splinter pushed in it throbbed just a bit when he hit that special spot inside.  He really needed to ask Donatello about that later.  It was fun to see and he wondered if his lover really could cum just from being penetrated.  If he hadn't been close himself he would have asked then.  If he hadn't been so close he probably would have been a lot more concerned about about what Donatello had just said to him, too.

	Instead he just nodded and kept going. "I am getting close... Right there, actually."

	"Me too!" Donny sucked in deep breath and tensed and the edge.

	He didn't try to hold back.  Splinter had been very good inside him and he'd fantasized about it before while his brothers had pounded his ass instead.  The heat of his dad's cock, the feeling of his dad's soft scrotum bumping against his shell and inner thighs, and the enthusiastic rhythm of his dad fucking him had all been very exciting for him.

	His inner muscles clenched around Splinter's cock as he came from just the penetration.  His head tipped back deeper into the water in bliss and he gave a loud grunt of release.  Splinter looked down just in time to see a strong blast of semen suddenly spurt from his son's tip.

	"Just ... from taking it..." The strain of his own impending orgasm made speaking slow for him, but it was an impressive sight that stayed with him with his own peak hitting him hard and sudden.

	His eyes clenched shut with a grimace of pleasure but he could still see Donny cumming hands free as though they were open.  He hadn't realized how much movement there could be in an ass, but Donatello's was flexing around his dick just right to push him over the edge.  There weren't many thoughts beyond that with his orgasm making him think only about how good and happy he felt while his cock pumped his seed into his lover in pulse after pulse of pleasure.

	Leonardo, Michelangelo, and Raphael watched jealousy from the side.  All three of them would have loved to have been their father's first real partner.  As much as they enjoyed seeing Splinter from such a good position, being under him would have been so much more fun.  They all wondered what he would have felt like inside.  Donatello had obviously liked it.  He did look good throughout his orgasm, too, with his body tense and his face intense.  The blissful pose only lasted a few seconds before he came down though, then he looked spent and droopy.

	Splinter slipped out almost immediately after his orgasm faded and he stumbled backward to sit heavily on the nearest stool. "Thank you, that was very good, Donatello." He took a long deep breath, tired, out of breath, and suddenly extremely embarrassed by what he'd heard his son say perhaps a minute ago.  When he felt that he and his legs were up to it, he stood. "I did enjoy this, but I feel I must be alone for some time.  I must meditate to calm my mind and work through some things.  You may all stay here and do what you wish or you may do your usual things in the lair.  I will see you all later."

	The turtles watched him go.  He moved as calmly as he could, but there was an unsteadiness that they were not used to seeing in him.  It was not from exhaustion.  Their master clearly had a lot on his mind after all that.  They did too, such as how good his ass looked on the way out and how soon they'd get a chance to spend some one on one time with their tall handsome sexy dad.
