Leonardo felt his body relax as he felt his mentor's hand on his shoulder.  Even in a time like this, that simple gesture could wipe away any tenseness or, in this case, shame.  He took a deep breath, still wishing Master Splinter hadn't walked in his room a few minutes ago.

	"My son, you and your brothers are humanoid, just as I am," Splinter said gently.  "Whatever that ooze was derived from, it must have had human DNA.  You have many of man's traits, including their wanton desires.  It was perfectly natural, what you were doing."

	Leonardo had always believed in the wisdom of his father.  He had been wrong about very few things.  But still, he was ashamed for what had just happened.  Any teen would be embarrassed after getting caught by their parent while masturbating.  
	
	He had been lying on his bed, stroking his cock with one hand, and with his other, he was fondling his testicles.  He had nothing to fantasize about, so he simply laid back and enjoying the feeling of his hands on his private parts.  He had removed all bands and gear from his body, leaving him completely naked.  He had discovered this pleasure a few months back, when he was trying to get rid of an erection, but he didn't know how.  He had tried peeing, but to no avail.  He thought he could coax the urine from his body by stroking himself.  So after about forty five minutes of stroking he was pleasantly surprised when he didn't have to pee after all.  Instead, he felt a sensation like he had never felt before.  It was as if every nerve in his body had suddenly lit up.  And the substance that came out of his penis definitely wasn't piss.

	He was thoroughly enjoying his masturbation session, so much that he didn't even hear the door open.  Then again, he couldn't be too surprised at that.  Master Splinter could be quite silent when he wanted to.  He was surprised, however, when he felt a hand on top of his scalp.  He stopped suddenly.  The hand had four small furry fingers, instead of three fat reptilian ones, so he knew who it was immediately.  He didn't have to open his eyes to know that one of his brothers had not interrupted his  private moment.  He opened his eyes anyways, and looked up into the eyes of his master and adoptive father.  He felt his hands come to a slow stop as his heart filled up with sheer terror.  

	However, Master Splinter wasn't looking at him the way Leo had expected him.  He had initially expected his father to be wearing a face of cold fury, but instead, the rat looked at him with an affectionate smile.  This confused the young warrior, as he always thought that this act was not something of which his father would approve.  He thought it showed a lack of discipline and restraint.  He thought Master Splinter would scold him for not being able to control his urges.  But looking up into Master Splinter's eyes, he didn't see any of the belittling anger he had expected.  

	Leonardo swallowed, placed his hands by his sides, slowly sat up in his bed and looked down at his father's feet.  He didn't think he could looked him in the eyes right now.  Despite his father's lack of anger, he was mortified at being caught doing what he was doing.  He was at a total loss for words.  He felt the bed shift and squeak as his father sat down beside him on his left side.  

	"Leonardo, are you alright?"  He asked, with genuine concern in his voice.  
	
	Leo looked at his beloved ninjutsu instructor.  What kind of question was that?  The answer was both yes and no, but what would he say to his father.  
	
	"Leonardo, please, do not be afraid.  I am not upset with you."  

	These words comforted him only slightly.  However, as he was still in a deep state of fear and shame, Leonardo began to babble out the truth, as he could never lie to his father.  

	"M-master, please.  I'm so sorry.  When this happens to my body, I need to do something about it.  I found that this helps me relax, and---"

	He was cut off as his master shushed him and pulled his head in and kissed his temple.  He felt a great breath escape him, and he felt a tear roll down his cheek.  He didn't know where that had come from.  Maybe it was panic's way of leaving his body.  And it had left his body.  Splinter wasn't berating him like he had always imagined he would if he ever got caught doing this by him.  Instead, he was calmly and gently reassuring him that he had human DNA inside of him, so he had many of their same urges and desires.  That this was perfectly OK and natural.  But then what was he doing in his room?  If Splinter hadn't found this act as deplorable as he thought he would, then why had he come into Leonardo's room and interrupted him?  Why not just leave him alone and go about his business

	Splinter looked at his son.  He was glad to see he had calmed down enough to realize that his father was not mad at him.  Quite the opposite in fact.  Splinter was always aware that this day would come eventually.  He and his sons were half human, after all.  He suspected the boys had begun to get erections, even masturbate, a while ago.  He was even a little bit mad at himself for not telling they boys about their bodies sooner.  Now, he had the perfect opportunity to fully teach his eldest son about his own sexuality.  Maybe even take care of his own needs in the process.  

	He took his left hand and placed it on Leonardo's left shoulder.  He kissed his son's cheek.

	"Leonardo, I am the one who should apologize, not you.  I did not have the courage to discuss this matter with you, and now you believe you have done wrong.  You have not.  And I am sorry for making you believe you should be ashamed of these urges."  

	Leo studied his father for a moment.  It felt so good to hear him say that.  He had calmed down significantly, but if he hadn't done anything wrong, what was he doing here?  Why didn't he just let him finish what he was doing?  He had always trusted his father, and he was curious to see what he wanted.  He felt comforted by Master Splinter's kiss on his head, as well as both of his hands on his shoulders.  He looked down and noticed his erection had understandably failed him.  He looked back up at his father's gentle face again.  What he was about to ask wasn't going to be easy, but Splinter's gentle touch helped.

	"Master, If I have done nothing wrong, then why are you here?"  When he asked this question, he was afraid that Splinter would have his feelings hurt, as if he didn't want him in his room.  Which he did.

	Splinter simply looked at his son with love.  He smiled, and then leaned in and kissed his son again, only this time on the mouth.  He had never done that before.  He took his left hand and caressed Leo's chest.  He studied his son for a moment, then spoke.  

	"My son, you are at an age now where you will have feeling and desires you will not understand.  They are normal.  I am here to teach you of these feelings.  If you will permit me, I will teach you about your sexuality.  I know you have been masturbating for a year now, just as your brothers have, as well.  But soon you will grow tired of your own touch, and you will want more.  I am here to give you more.  But only if you will be comfortable with this.  Will you allow me to teach you these things?"  

	Leonardo stared into his father's eyes.  He realized then that his right arm was clasping Splinter's hand to his chest, and that his left arm was wrapped around Splinter's waist.  He didn't remember when he had done that.  Maybe it was Splinter's kiss.  This time, it was directly to the lips.  It had caught him off guard, but it wasn't unpleasant.  The kiss was full of gentle love and reassurance.  And now his father was not only forgiving him of his actions, but he was offering to teach him how to do more than just touch himself.  He hadn't had any sexual experiences other than masturbation, and he didn't know what two people, especially two males, could do with each other that would make him feel as good as jerking off did.  He was curious to see what Splinter had in mind.  He felt his father's hand move towards his stomach.  He looked at the rat and gently nodded his head.  

	Splinter smiled.  His son was willing to learn, and he was more than willing to teach, but not at the expense of his son's comfort.  He wanted this to be a pleasurable experience for the both of them.  

	"Leonardo, we will be doing things with each other.  Things that require us to become very familiar with our bodies, and each other 's bodies.  This is your first time experiencing this sort of intimacy with anybody, so you will be naturally nervous.  I will guide you every step of the way, but if at any time you begin to feel uncomfortable with what we are doing, you must tell me.  Understood?"

	"Yes, Father.  I'm willing to learn whatever you have to teach," he said.  "Besides, this seems like it'll beat push-ups and pull ups any day."

	Splinter was happy to hear his son joking.  He was in a positive mood, and that meant he was ready.  He leaned forward and kissed his son again.  This time, his son kissed back. 

	"Our first lesson will be kissing.  It is the beginning of all acts of love between two individuals, and it is a perfect way to show your companion your love and passion for them.  There are many different ways to kiss.  When we kiss again, let your passion guide you."  

	Splinter pressed his mouth to Leonardo's beak, and was surprised at his son's enthusiasm.  Leo hadn't been as timid as he was before.  He put his hands on Splinter's shoulders and kissed his father.  Splinter had kept his mouth closed for now.  He didn't think Leo was ready for another tongue in his mouth.  But now, Leo was insistently pressing his lips onto his own,  and Splinter knew that his son was having trouble controlling his libido.  He believed he was ready.  Splinter  let his lips part slightly and snaked his tongue out to lick Leo's lips.  Leo opened his eyes briefly in surprise, but closed them again.  He put his hands on the back of his father's furry neck.  He felt Splinter lick his lips, and figured that he should do the same.  He snaked his tongue out, and met Splinter's tongue with his own.  

	Splinter was thrilled.  Leonardo had taken to this lesson much faster than he had anticipated, and now he was allowing him to kiss him with his tongue.  They explored each other's mouths with their oral muscles.  Since Leo was already used to french-kissing, perhaps it was time to move to greater things, Splinter thought.  He let his hand run down Leo's chest and belly, pausing to rub what he believed was Leo's ticklish spot.  Leo gasped and giggled.  Splinter pulled away and looked at his son with amusement.  

	"Do not be afraid to allow your hands to explore your partner's body," He instructed.  "I am here for your pleasure, my son.  Touch me wherever you feel comfortable touching."

	Leonardo believed he knew what he meant.  He reached up and began to scratch the back of Splinter's head.  He had read somewhere that cats enjoyed that sort of attention.  While Splinter was no cat, Leo believed it was worth a try.  The worst that could happen was that his father would gently guide his hand to another part of his body.  

	While Splinter hadn't expected the sudden head scratching, he was enjoying it.  Leo's strong fingers felt good on the fur of his scalp.  He leaned his head back, closed his eyes, and chuckled slightly at his son's efforts.  He let his hand go further downward towards Leo's crotch, and paused.  He wanted to be sure that his son was ready for that sort of attention.  He gasped as he felt Leo's wet mouth on his neck.  His student kissed his throat through his fur, and it felt delightful.  Especially when he darted his tongue out and licked his neck.  Splinter growled in appreciation.  Leonardo had always been a fast learner.  Splinter knew it was time to move on.

	Leonardo was thoroughly enjoying himself.  The sensations and feelings he had now were indescribable.  He loved his master dearly, and now he was showing his love in ways he never imagined.  He was glad he got caught jerking off.  He felt his father's hand on his stomach, and he felt his cock jump back to life.  With one hand he continued to scratch and rub his father's head, and with the other, he rubbed Splinter's chest.  He hand rand over the soft fabric of the deep red kimono.  Splinter bent his head back down, and took Leo's mouth in his again.  

	Splinter felt his son's hand on his chest and knew Leo was ready.  While he slipped his tongue back into Leonardo's mouth, his hand reached down and places his hand on his son's genitals.  Leo gasped into his father's mouth.  His grip tightened up on his father's kimono.  Splinter gently fondled Leonardo's testicles.  He took hold of his son's penis, and was delighted to feel blood slowly being pumped back into it.  He also felt one of Leo's hands press harder on the back of his head, meaning he wanted to kiss his father harder. The other hand slipped inside his kimono and rubbed his chest.  

	Leo never thought just how good another person's hand would feel on his genitals.  It was amazing.  And the fact that it was his adopted father's own hand on his penis thrilled him.  He wanted to please Splinter in return so badly, but was still a little apprehensive about touching his father that way.  He didn't think Splinter would mind if he took things a little slow.  He continued to rub Splinter's chest and head, as well as make out with the rat.  He felt a nipple under his palm, and decided to focus on that.  It worked, as Splinter broke the kiss and groaned.  Leo rubbed and caressed his father's nipple under his fur, and Splinter responded by licking his neck and squeezing his dick harder.  He moved his hand to Splinter's other nipple, and gave that one a slight squeeze.  Despite his age, Splinter worked out and exercised at least three hours a day, so the old rat was no slouch.  In fact, Leo wondered just how old the rat really was.  How old was he when he came across him and his brothers lying in that pile of radioactive ooze?  He might not have been that old.  His fur was still a luscious shade of brown, and--

	Leo's train of thought was cut off as Splinter got up from the bed and stood in front of Leonardo.  Splinter had had enough.  Leo's hand on his chest was wonderful, but he wanted more.  To show that his student had done nothing wrong, he held Leo's face with both of his hands and continued to kiss him deeply.  With his mouth still on his son's, he let go of Leo's face, and sought out his hands.  He took his son's hands and guided them to the tassels holding his robe closed.  He pulled back and looked at his son with pride.  

	Leo stared at his father's mid-section, unsure of what to do next.  He then got an idea.  Splinter's hand felt so good on his cock, and he wondered what another cock would feel like in his hand.  He let go of Splinter's robe with one hand and maneuvered it towards his father's crotch.  He stroked his master's thigh, loving the feeling of the thick, lush fur running through his fingers.  He even reached around to grope Splinter's buttock under his robe.  He shifted his other hand and gently reached out for his father's private parts.  He found them, and was thrilled.  He cupped the furry scrotum in his hand, feeling the weight of the testicles.  He then put his hand on his father's sheath, and found that the penis inside of it was rapidly coming to life.  This made him happy.  To know that he was giving back as much as he was getting exited him.  He looked up at Splinter, who was was staring down at him with love and lust.  Splinter bent down and kissed his son's head.  Leo leaned forward and kissed Splinter's furry chest, moving his kimono aside with his mouth.  Leonardo was enjoying his father's body, but he believed he could enjoy more of it if the kimono were out of the way.  Why else would Splinter have put his hands on the ropes that tied it shut?  He took his hands away from Splinter's butt and genitals and worked open his father's clothes.  It was tricky at first, as he had never done this before.  At last, the knots came loose, and the robe fell open, giving Leo an unobstructed view of his father's body.  He looked up at his father.

	Splinter was staring at him with affection.  His son was doing so well, and it felt so good exposing his body to him.  
	
	"You're doing wonderful, my student.  Now, let your hands roam over my body.  Touch me any where you wish."  

	Splinter closed his eyes at the feel of soft hands running over his fur and flesh.  Leonardo's hands traveled far, touching his chest, his stomach, his hips and his thighs.  Splinter groaned in pleasure as he felt his penis being played with again.  Leo's hands were so young, so eager to please.  He wanted his son to touch is buttocks and kiss his chest again, so he drew himself further into Leo's embrace.  When he closed the space between the two of them, Leo had no choice but to wrapped his hands around his father.  He ran his hands up and down Splinter's back and ass.  When Splinter felt those hands on his ass, he wanted to make sure Leo knew he was doing right.  He pushed his ass into his son's strong hands, and his chest into his face.  Leo was a fast learner, and he squeezed the furry rump.  Splinter guided his face to one of his nipples, hoping the boy would get the idea.  He did, and Splinter could barely suppress a yell as he felt moist warmth over his nipple.  Leonardo sucked and licked the pink bud of flesh before him with enthusiasm, and Splinter couldn't help but grind his cock up against Leo's chest.  Leo moved to the other nipple, being tickled slightly by Splinter's fur.  With his hands, he continued to stroke Splinter's backside and tail base under the old garment.  Splinter pulled his son's head off of his chest and looked at him.  He reached down and kissed his son again, not holding back in his passion.  His blood was on fire, and he knew Leo's was too, for he was trembling.  He put his tongue deep into his son's mouth, and Leo responded with equal force.  During the kiss, he felt Leo's hands on his shoulders and push his robe completely off.  He maneuvered his arms to assist, and was finally naked in front of his student.  He put his hands back on Leo's cock and balls, and began masturbating him.  But he didn't want it to end like this.  

	"How has it been thus far, my son?" Splinter asked in Leo's ear.  

	Leo could barely calm himself down to speak, but he finally managed to say, "Oh, god, Father, I, uh, um, what do we do next?"

	Splinter smiled, and then knelt in front of his son.  He leaned his head forward and licked Leo's chest.  Despite their chests just being hard shell, he knew that the turtles could feel through them, and his tongue sought out the place where he believed his nipples would be.  Leo gasped and moaned.  Splinter continued to kiss down his student's firm chest and stomach, pausing to lick the ticklish spot he always knew was there.  Leo sucked his gut in and giggled slightly.  Finally, Splinter reached his target.  He sat on his knees and stared at his son's green penis.  He took it in his hands and stroked it firmly.  He used his free hand to stoke his son's testicles.  He looked up at Leo's face, and saw pure pleasure.  He believed he was ready for the next step.  

	Leo leaned his body back as far as it would go.  His father's hands felt amazing as they caressed his genitals.  He held his head back, and closed his eyes as Splinter did his magic.  Suddenly, he felt a wet, rough sensation on the underside of his penis.  He gasped loudly, and looked down at his master.  Splinter was gently licking his cock.  His eyes were shut as he slowly ran his tongue up his son's shaft.  He was still playing with Leo's balls.  Leo yelped as Splinter let his tongue drag over the crown of his erection.  Leo looked down at his father, and was surprised to see Splinter looking up at him, even while continuing to lick the green cock before him.  Leonardo smiled at his father, and reached down and stroked his father's head.  Then his father did something different.  Splinter stopped licking and put his lips on the tip of the shaft.  Leo could feel a slight sucking sensation, and it drove him wild.  Then Splinter did something better.  He moved his head forward, so he was actually taking Leo's penis into his mouth.   Having his member surrounded and engulfed by moist warmth was exquisite.  When he felt Splinter's lips touch is crotch, he thought he was going to pass out.  His own father had his entire dick in his mouth, and it felt amazing.  

	Splinter pulled back, sucking hard as he went.  Looking up at his son, he knew he was doing right.  Splinter knew what he was doing.  On his travels to the Nexus, he had taken many lovers there, both male and female.  He had had plenty of practice, but he had always wanted his sons.  He wanted to share the joys of sex with those he loved the most.  In feudal times in Japan, it was perfectly acceptable for a master to begin a sexual relationship with his student.  Such acts would form unbreakable bonds with the two warriors.  Splinter had just the tip in his mouth, and then he thrust his neck forward, sinking down on the green cock in his mouth.  Splinter loved the taste of his son's maleness.  He gently massaged Leo's testicles as he fellated the turtle.  Splinter looked at his pupil.  He was leaning back as far as he could without hitting the wall.  Even so, that was far enough to expose his asshole to his father.  Splinter took advantage of this, and took two of his fingers and gently massaged Leo's perineum and anus.  Leo gasped, and an thrust his hips into his father's face.  Splinter sucked harder, and gently pushed his fingers against his student's ring.  

	Leo had never felt anything like what he was feeling now.  His master was not only sucking on his penis, but it felt like he was pushing his fingers into his ass.  Leo had to suppress a yell, as he didn't want his brothers walking in on this.  Splinter continued to push his fingers into Leo's rectum, but they wouldn't go in.  He tried using only one finger, but to no avail.  Leo had never been opened like that.  This was going to require some lubrication.  Leo leaned back, closed his eyes and opened his mouth in pleasure.  Suddenly, he felt something skinny, furry, and strong press into his mouth.  He opened his eyes, and saw that Splinter had pushed a finger in his mouth.  The turtle clamped his mouth shut around the digit.  He decided that he liked having his anus played with by his father.  He wanted to feel this finger dig into his ass.  By now, he was willing to try anything.  He sucked on the finger, making sure it got nice and wet.  Splinter was still pressing his other fingers against Leo's rectal opening, gently massaging the ring of flesh, but never pressing in.  Leo felt the finger leave his mouth, and ran his tongue along the digit as it left.  

	Splinter was glad Leo had gotten the message about what he wanted the boy to do to his finger.  He was not resisting the sensation of his asshole being played with.  He took his now slick finger and began to push it into Leonardo's anal opening.  Covered in spit, it slid into the young turtle with ease.  Still sucking firmly on Leo's cock, Splinter looked up at his student, and saw that Leo was awash in ecstasy.  Splinter was broadening Leonardo's horizons in ways the terrapin could never imagine.  The old rat felt his son's insides contract around his finger.  Leo followed the clench by bucking his hips into Splinter's muzzle.  Splinter responded by pushing his finger fully into Leonardo, all the way up to the knuckle.  With his finger in place, he dug around inside, searching for his student's prostate.  He found it, and gently massaged it with steady rapid strokes.  

	Leonardo had to fight not to scream in pleasure.  His adoptive father was doing things to him that he never thought possible.  Splinter's fingers had reached something inside of him, and somehow he was getting pleasure from it.  He never wanted it to stop.  Most unbelievable was who it was giving him this pleasure.  His master and father.  And the sheer taboo of that only drove Leo faster to his climax, which he could feel building in his loins.  He couldn't help but let out a cry of joy and Splinter sucked and fingered even harder.  He had to warn his father.

	"Master, I, I, ah, I'm gonna,  aaaAAHH!!"  But no matter how hard he tried to warn Splinter, the rat just kept on sucking and fingering.  Even when Leo's climax hit like a tidal wave and he ejaculated hard into the mouth of his sensei, Splinter continued with his blow job.   

	Splinter's eyes widened for a moment, and then drifted closed.  He  pulled his head slightly back so he wouldn't choke on his son's cum.  This being the first time Leo had ever experienced anything like this,  Splinter suspected that the volume of the load would be great.  He was right, as Leo's seed quickly filled up his mouth.  He didn't want to have to clean up a mess, so he swallowed as much semen as he could.  While Splinter sucked and swallowed, he reached down in between his legs and stroked his own hard dick.  He contemplated on how to use it on his son.  He wanted to be enjoyable for both of them.  He remembered how good it felt when he rubbed his penis up against Leo's chest, and the boy had even willingly massaged his sensei's cock, ass and nipples.  Leonardo was willing to please his father, but for now, Splinter was content to simply allow his son to recover from his first blowjob.  

	Leo squeezed his eyes shut and rode out the last wave of his climax.  All of his attention was focused on his abdomen right now.  His father's mouth sucking his seed out of his testicles.  His father sticking two fingers deep into his ass and rubbing something that made him feel wonderful.  He didn't notice that his neck was in an uncomfortable position until he was through coming.  It was then he felt a pain in his neck, as he had been leaning his head back against the wall next to his bead, and his neck muscles were getting sore.  He sat up straight just as Splinter pulled up off of his crotch and out of his ass.  He was about to lay back down on his bed when Splinter suddenly covered his mouth with his own.  Leo' eyes snapped open.  He could taste his own cum on his father's lips and mouth, but in the heat of the moment, he found that rather pleasant.  Leonardo relaxed as Splinter placed his hands on his neck, holding still in the kiss.  Still kissing him, Splinter pushed Leo back down on his bed, and laid down on top of his son.  When Splinter was laying flat against his son, Leo couldn't help but notice his master's rampant erection being pressed up against his wet groin.  He wondered what Splinter had in mind for them next, but for now, he was content to explore Splinter's body with his hands and his mouth with his tongue.  He ran his hands down his father's body.   He cupped and squeezed Splinter's ass.  Splinter humped his hips against his son harder at the sensation of Leo's fingers probing at his backdoor.        

	Splinter didn't think this night could have gone better.  He never dreamed his son could be so ready for what they were doing.  Leo was brazen enough to even to gently stroke his father's anus with this fingers.  Splinter loved the sensation, but he wanted his seed inside his son's body, not on it.  If he didn't stop himself, he was going to make an even bigger mess of Leo's crotch.  With great effort, he pulled off of his son's mouth and sat up, straddling the turtle's hips.  He looked down at his son with a look a passion which Leo had never seen in his father's eyes before.  Splinter rubbed Leo's chest for a moment before speaking.  

	"Well, my son?  How was your first climax with another male?"  

	Leo looked at his naked father sitting on his waist.  He eyed the prominent erection that seemed to be staring straight at him.  He knew that this session was not over.  He didn't want it to be.  Seeing Splinter's rampant arousal had to be taken care of, he decided.  It wouldn't be right to not give him equal pleasure.  He ran his hands up Splinter's firm, muscular thighs.  He took his father's hard cock in his hand and stroked and squeezed it.  With his other hand, he gently massaged the rat's testicles.   Splinter closed his eyes and let out a low, soft growl.  He leaned back to allow Leo easier access and closed his eyes, deeply enjoying his son's attentions.

	"Father, this is one of the greatest nights of my life.  Thank you for this."

	Splinter looked at his son and beamed proudly.  There was a reason why he made Leo the leader of the turtles.  Splinter's cock began to leak precum, and Leo's hands were spreading it up and down his shaft.  His penis was was getting very slick with each stroke of his son's hand.  And his son's anus was already loosened up from his fingers.  Even better, Leonardo seemed to greatly enjoy prostate stimulation.  Perhaps he was ready.  But Splinter had no intentions of harming his son.  He had to make sure that his son was ready for such an act of love as the one he had in mind.  

	"You are very welcome, my son.  Tell me, when my fingers were inside you, how did that feel?  Was it pleasurable?"

	Leo flashed back to the sensation of his father's fingers knuckle deep under his tail.  He remembered how the digits were pressing up against something inside of him.  And every time they did, the sensations were indescribable.  But they did feel good.  However, as enjoyable as that was, he knew that it would not be fair to take so muck pleasure and not give any back.  Having his penis being sucked on by his sensei was exquisite.  He knew Splinter would enjoy it, and he knew he himself would enjoy getting to taste his father's masculinity.  

	"Oh, yes, Father.  It was.  But what about you?  You still have an erection.  If you want, I can do to you what you just did to me.  I can take it in my mouth, if you wish."  

	Splinter looked down at his student and smiled.  Leonardo was always the most eager to please his master.  His brothers had always berated him for that.  Splinter most certainly wanted pleasure from his son, but he couldn't decide whether or not he wanted Leo's mouth or ass.  Leo had volunteered his lips and tongue into service, so oral sex it would be.  Perhaps later, he would penetrate his son, but for now, he looked forward to having Leo's eager mouth drooling over his raging erection.  

	Leo rubbed his father's chest, enjoying the feeling of the hard muscles underneath.  He looked up and down Splinter's body.  He wanted to give his beloved master the pleasure that he was given, but the position they were in made it difficult.  But Splinter seemed to have that problem solved.  The old rat bent down to kiss his son deeply one more time.  Leonardo eagerly pushed his tongue into his lover's mouth.  Splinter rose up again, and then began walking on his knees towards Leo's face.  Leo watched as his father moved his body so that he was now sitting on Leo's upper chest, rather than his crotch.  Splinter's raging arousal was now mere inches away from his face.  His father shifted again, and his knees were now under Leo's armpits.  Leo had no choice but to lift up his arms and wrap them around his father's waist.  Splinter rose up on his knees, so that his penis was directly in front of Leo's mouth.  Leo took the hint, and stuck his tongue out to gently lick the head of his father's member.  He nearly choked on the masculine musk that wafted off of the organ.  The taste of the cock was salty.  He once again reached around to cup Splinter's buttocks.  He squeezed and caressed the firm muscles while relishing the feeling of the fur in his hands.  Splinter must have enjoyed this, because he thrust his hips towards his son's face.  Leo looked surprised as he suddenly found himself with a mouthful of rat cock.

	Splinter grasped the backboard of Leo's bed and groaned loudly at the wonderful wet heat surrounding his dick.  He looked down and saw Leo looking up at him with eager eyes.  He reached down and stroked his son's face.  Looking at his expression again, he believed Leonardo was looking for approval for his oral efforts.  He responded by easing his dick further down Leo's mouth.  Splinter hoped that Leo had learned a few things while he was sucking the boy's cock, like keeping his tongue over his bottom teeth to prevent scraping.  And he did, as Splinter relished the semi-rough surface of his son's tongue scraping the bottom of his dick.  He closed his eyes and failed to suppress a throaty growl at the young turtles wet mouth consciously sucking harder on his penis, as well as the strong hands massaging his ass.  He bucked and moaned on Leo's chest.  He had to be careful, however, of the lad's upper teeth.  Leo, however, seemed to sense this, and Splinter could tell that he was being cautious about this as well.  

	Leonardo couldn't remember when he had enjoyed himself this much.  He loved being this close to his beloved father and master.  He loved that Master Splinter trusted and loved him enough to trust him with the most sensitive and precious part of his body.  And he loved seeing Splinter's look of bliss when he took the old rat's cock as far into his mouth as it would go.  Leo drug his tongue back and forth on the underside of Splinter's penis.  Yet he was careful enough to make sure his top teeth did scrap along the top of his master's tasty member.  He relished the taste of raw masculinity in his mouth.  He squeezed his father's vulnerable buttocks harder, causing the rat to buck his hips forward and his his dick in Leo's mouth.  Leo had and idea.  He had greatly enjoyed his master's fingers probing his anus, and he wondered if Splinter would enjoy that sort of thing as well.  But he knew he couldn't put his fingers in dry, so he took his hands off of his father's ass, and let them roam up his furry body.  He stopped to gently rub his chest, and tweak his nipple a bit.  He could see that Splinter was making an effort to not moan so loud as to awaken the other turtles.  Leo smiled around the dick in his mouth, and then moved his hands up to Splinter's face.  Splinter seemed to know what Leo was up to, because he took one of the turtle's fingers into his mouth and began to suck on it.  While he was enjoying the sucking sensations on his finger, Leo suddenly felt something else attempting to probe it's way into his mouth.  Leo looked behind Splinter, and noticed that the old rat was trying to stick his tail into his son's mouth.  Leo was happy to oblige, and loosened his lips slightly on the rat's penis.

	Splinter was thrilled to have his tail and dick in his boy's mouth at the same time.  He knew what Leo wanted to do next, but Leo's finger's were quite bigger than his own.  He knew that he would not only have to get the finger extra wet and slick, he would have to prepare his own body if his son was to finger fuck his asshole.  While he loved the gentle yet firm sucking on his tail, he knew he would have to remove it if he wanted to do what he felt needed to be done.  When he was certain his tail was slick enough, he gently pulled it out of Leo's mouth, and maneuvered it back between his son's legs, and under his son's testicles.  Leo seemed to know what his father wanted, so he spread his legs, and allowed his master to insert his tail into his still loose anus.  Splinter felt the turtle moan around his throbbing dick, and that made it all the more difficult to what he had to do next.  With great effort, and with the green digit still in his mouth, he gently pulled his hips back, and pulled his cock out of Leo's mouth.  Leo looked confused for a moment, until Splinter hoisted his weight up and over the turtle's face.  He paused to allow his son to lick and suckle his balls for a moment, and then the view of the Leo's face disappeared completely as he sat down on his head, making sure the turtle's beak was wedged into his butt cheeks, and the boy's mouth was as near his anus as he could place it.

	Leo was very surprised at this new move his father just made.  At first, he feared that there would be an unpleasant odor, but then he remembered just how clean his father could be.  Splinter took great care of himself, and he smelled quite nice to Leonardo.  Even his father's anus, which was pressed up against his mouth, smelled pretty decent.  After a moment's pause, he felt the old rat buck his hips, thus grinding his asshole across Leo's face.  Then, it struck him what Splinter wanted.  While Splinter was preparing Leo's finger's, he was expecting Leo to prepare him.  Tentatively, Leo stuck out his tongue and pressed to his father's opening.  The taste was not bad at all, rather, it was very masculine, and Leo loved it.  His father must have loved it to, because Leonardo could feel his father shiver at the sensation.  He heard his master groan loudly around his finger, almost loud enough to wake his brothers, and he found the courage to dig his tongue harder and deeper into Splinter's ass.  In response, his master pushed his own tail deeper into in own ass.  Above him, his father got off of his knees and squatted down on his feet, thus opening his butt more for Leo's access.  Leo pushed his tongue as far into Splinter's asshole as it would go.  He reached up and stroked his lover's painfully hard penis.  

	While Master Splinter adored his son's tongue inside of him, he didn't want to climax like this.  Again, with effort, he hoisted his hips off of his Leo's face and sat back down on the boy's chest.  He pressed his dick up against Leo's mouth, and was happy when his student got the message and opened his beak to allow the old rat access.  Splinter thrust his hips forward and buried his penis in his son's mouth once more, shivering at the moist heat and the eager tongue bathing his manhood.  Splinter was fairly certain that Leonardo was by now used to giving head, so he humped his son's face with reckless abandon.  He felt something move in his own mouth, and remembered he was sucking on his son's fingers.  He was certain that they were ready for his backside.   He grabbed Leo's forearm and pulled the limb away from his face, and guided it towards his posterior.  Leo knew what to do then, because he pulled his arm free from his master's grip, and buried his hand in his furry ass.  Splinter stopped his face fucking momentarily when he felt something hard and alive poking at his backdoor.  He forced his body to relax as Leo's fingers opened up his anal ring.  Even with the finger sucking and the aggressive rim job, his son's fat digits in his asshole was a tight fit.  Leonardo seemed to sense this, and was careful in his penetration, as he gently eased his fingers deeper inside his father's body.  Splinter also felt his son power up his cock sucking to take make the going in a little easier.  It had been a long time since Splinter had been to the Battle Nexus, and while there, he had taken on many male lovers.  So this wasn't a completely alien feeling to him.  Splinter slowly backed his hips up, puling his dick out of his son's mouth, until only the crown remained in, and at the same time, he pushed is ass onto Leo's exploring digits.  Finally, the fingers were as deep as they were going to go.  Splinter sighed heavily at the pressure on his prostate.  He wondered if his boy knew where he was touching him.

	"Leonardo, I am enjoying your fingers inside of me very much,"  Splinter said, reaching down and placing a hand on his son's head.  "You are doing so wonderful.  Now, do you remember the pleasure you received when I was doing this to you?"

	Apparently, Leo was having a great time with his master's dick in his mouth, because he only nodded yes.

	"What you felt was called you prostate.  It is a gland hidden inside the rectum of all human males,"  Splinter explained while easing his penis back into Leo's mouth.  "We have one because of our mutation.  The prostate produces semen, which is what is need for a female to be with child.  This gland can also be very pleasurable to males, when stimulated correctly.  Right now, you are touching my prostate with your fingers, and you are giving me great pleasure, my love."  

	Leo blushed at what Splinter called him.  My love.  With that statement, he truly felt like he and Splinter were equals.  He pressed in harder with his finger, eliciting a throaty groan from his lover.  He sucked as hard as he could on Splinter's penis.  He had been surprised when his father had swallowed his cum, and he wondered what it could be like to do the same.  With one hand stimulating Splinter's ass, Leo's other hand was free to roam.  He reached up and stroked Splinter's face, and then brought his hand lower to rub and pinch his master's pert nipples.  Above him, the rat had his eyes closed, and he was wearing a very satisfactory look on his face.  From the sounds that Splinter was making, Leo believed that his father would soon climax, which Leo eagerly anticipated.  He wanted to taste his father's seed.  He wanted his master to share his orgasm.  He could feel the rat's tail twist and turn and pump inside his own asshole.  As a result, his erection had returned with full force.  He wondered what he and his master were going to do once Splinter had climaxed.  He hoped that his father would not leave him in this state of arousal.  

	Splinter began to actively hump his son's face, thrusting his cock in and out of Leo's mouth, and dragging his ass along the young turtle's chest.  He felt his nerve light up with the steady approach of his orgasm.  It was difficult for him to keep his self restraint while fucking Leo's mouth and fingers, for he did not want to choke the lad on his own cock.  His fur was wet and shiny with the sweat of his efforts.  He was desperately trying to keep the volume of his pleasured grunts to a minimum for fear of drawing attention from his other sleeping sons, but it was very difficult with Leo's wet, hot mouth and his strong, aggressive fingers jamming up against his prostate.  He couldn't help but moan a little louder as he began to climax into his son's mouth.  He knew Leonardo would have trouble swallowing his cum, so when he peaked, Splinter made sure that his penis was only half way into Leo's mouth when he stopped his thrusting and came.  He threw his head back, let out a deep, guttural growl, and shot his load into his student's mouth.  The pleasure was indescribable as Leonardo continued to suck his cock, thus swallowing a great deal of his cum.  Leo also continued to dig his finger into Splinter's prostate, milking more seed out of the old rat.  Splinter couldn't help but slowly thrust in and out of his boy's mouth during his climax, though he was careful not to go in too deep.

	Leonardo blushed intensely when his father came in his mouth.  In his lust fogged mind, the rat seed actually tasted quite good to him, and he powered up his sucking as to milk his master for more semen.  He had to concentrate on controlling his throat, however, as he wanted to drink of Splinter's cum, but he didn't want to have to choke on it, either.  Leo continued to press his finger against the old rat's inner gland.  Smiling around the rat cock in his mouth, he looked up at his father, and was grateful at the sight he saw.  Master Splinter was wearing an expression of pure ecstasy and joy that Leo had never seen on his face before, nor did he think he ever would, before tonight.  The sounds coming from his furry lover were incredible.  Leo had a feeling that if it weren't for his brothers in there rooms trying to sleep, Splinter would have been crying out his pleasure as loud as he could.  But since neither of them wanted to be interrupted, the old rat had to settle for growling and grunting throughout his orgasm.  Leo loved hearing the sounds regardless.  The sounds, sensations, smells, taste and sight only served to pump more blood into his own proud dick.  Just when Leo wondered if his father would ever run out of ammo, the steady stream of semen slowly died down to a dribble into his mouth, and Splinter let out a deep sigh.  Leo felt his lover relax and settle his weight back down onto his chest, and he reluctantly allowed the deflating penis to slip from his mouth.  Splinter sat still for a moment, trying to catch his breath, then he slid his butt back down Leo's chest.  Leo's fingers, however, were still imbedded in the rat's muscled posterior, and when Splinter scooted back, he accidently put more pressure onto his prostate.  This surprised him, so much that an extra squirt of cum shot out of his penis and onto his son's face.  Splinter looked down, and couldn't suppress a slight chuckle at the sight of Lei's expression of surprise with a white streak of cum laying across it.  Leo smiled back, and laughed a little himself.  His laughter bounce his father up and down a little bit on his chest, and at this they laughed even harder.  During their laughing spell, Leo reached forward with his free hand and stroked his father's semi-hard cock, hoping to get another shot of rat seed.  It worked, and Splinter's hips jerked once more as he shot his boy right in the chin and neck area.  He then continued to slide back down Leo's body.  Leo tried to pull his fingers free of Splinter's gripping tunnel, but strangely, his master stopped him, grabbing his wrist and making sure the fingers stayed in.  

	"Leave them in, my son.  For what I wish to do next, I will need to remain loose."  Splinter said once he was lying back down on Leo's shell.  He rested his head on the terrapin's shoulder, enjoying his son's rising and falling chest as Leo breathed deeply.  Splinter inhaled, and he could smell his own cum on his lover's body.  He picked his head up and looked down at Leonardo with affection.  He once again had to smile at the sight of his eldest student's face covered his semen.  Leo smiled back, and Splinter couldn't hold back any longer.  He kissed his son's mouth with great affection.  Some of his own seed was on the boy's lips, and he licked it up and slipped his tongue into his lover's mouth.  He made sure to pass his semen off to his son, who took it with stride, sucking the sticky substance right off of his own father's tongue.  During the kiss, Splinter scooped some more semen off of Leo's forehead with his finger.  Splinter pulled back from his Leo's face and presented his cum-covered finger to his boy, who gleefully sucked on his finger, swallowing the left over seed.  While he was sucking the fingers, Splinter slowly kissed and licked his neck, making sure to get every last drop of his own jizz into his mouth.  When he was done cleaning Leo's face, he once more engaged in an intense kiss with his lover.  Since he had not swallowed, Splinter passed his own tasty semen into his son's mouth, digging in his tongue as deep as it would go.  Leonardo gladly returned the gesture, licking out all of his master's cum from his mouth while keeping one hand in his father's ass.  While he continued to massage his Splinter's secret inner gland, he held his head into the passionate kiss with the other hand.  Splinter was thrilled at the lad's eagerness during the kiss, and he had difficulty keeping his dominance.  Their lips were pressed together so deeply and tightly, that they both began to hurt.  This didn't stop them from each other's bodies, though, as Splinter began to hump Leo's crotch with his hips.  His pulse accelerated as he felt his son's raging erection grind into the fur of his inner thigh.  He kissed Leo deep and hard as his son bent his legs and brought them up in between Splinter's legs, forcing his sensei to spread his own legs and place them on either side of his son's waist.  He knew what he wanted, and he wanted soon.  Very soon.  With great effort, for he so loved kissing Leonardo, Splinter pulled off of his son's face and body.  He kneeled on all fours above his son, who strained to keep his fingers inside his master.  They slipped out, however, as Splinter suddenly flipped his entire body around, so that his ass was facing Leo, and his muzzle was mere inches away from that proud green erection.  Splinter settled down on top of his student once more, and Leo found himself with his own beak no less that two inches away from his daddy's asshole.  Splinter knew Leo would pick up the idea.  In the meantime, he stroked the boy's cock up and down, covering it with pre-cum.  He didn't dare take it into his mouth again, for fear that his son would loose control and peak once more, and Splinter had other plans for his son's semen.  As he stroked, he kissed the green penis up and down and all around, running his tongue over the boy's balls and inhaling deeply the masculine scent that wafted from the turtle's crotch.  He paused and smiled as Leonardo got to work himself, groaning at the sensation of something, small, soft, wet, warm and persistent licking his testicles and digging into his rectum.  
	
	Leonardo at first didn't know what to make of his father's actions, but what he did know was that the rat had immensely enjoyed the feeling of a warm tongue in his asshole.  Leo placed his hands on Splinter's butt cheeks and ran his oral muscle from the hairy scrotum up his lover's crack to the small pucker at the center.  He curled his tongue inwards and pressed into his master's entrance.  Still a little loose from the fingering, Splinter's ass opened with relative ease.  Still engaged in the rim job, he groaned at the feeling of a wet pair of rodent lips kissing his shaft and balls.  He bucked his hips up slightly into his father's pumping fist.  He thought he was going to feel his cock being sucked on once more, but Splinter continued to only kiss and lick.  This confused Leonardo, and it almost seemed like Splinter didn't want him to come again.  What else could he be planning?  Was it something better that oral pleasure?  What could be better that the feeling of a warm, wet mouth of his dick?  Leo thought this over while he squeezed his father's buttocks while licking the inside of his ass.  Whatever Splinter was planning, it was sure to be worth the wait.  He craned his neck forward to shove more of his tongue into his master.  With both hands free, Leo was once more free to manually explore Splinter's body.  He ran his hands through the thick, brown fur, relishing in it's softness.  He reached in between them, he tweaked Splinter's nipples, causing the rat to groan loudly and force his ass down onto Leo's face.  Leo brought his hands back to the furry buttocks, pulled them apart, and shoved his tongue as far as it would go into his father's body.  To add to the pleasure, he swirled his tongue around inside, and he smiled upon hearing Splinter gasp.  Splinter then surprised Leo by taking his entire cock back into his mouth.  The young turtle could feel his father's cold, wet nose pressed to his testicles.  He could also feel Splinter getting as much spit on his penis as he could.  Leo had to focus to keep his calm, as he suspected that his master wanted to do something else besides swallow his cum again.  But what?  Leo pulled his tongue out, and inserted his thumb into Splinter's asshole deep enough to hit his prostate again.  In response, Splinter humped his hips and crotch onto Leo's chest plate, grinding his rat dick against his boy.  Finally, Splinter pulled his mouth off his son's cock to speak.

	"Ah, Leonardo.  The pleasure you are giving me is so wonderful," he said, pausing his movements to looks back at his prized pupil.  Leo kept his finger in, continuing his prostate massage.  

	"By now, I believe we are both ready.  Would you like me to show you the ultimate act of love between two males?"  

	Leo, of course, eagerly nodded yes.  He wanted his beloved father to show him everything he had to show.  He couldn't wait to see how this could possibly get better.  Splinter smiled at him warmly, then gave his penis one final kiss and lick.  He then sat up and scooted forward to sit on Leo's chest.  Leo managed to keep his thumb in, and he reached around to stoke his father's cock with his free hand.  Splinter looked back at his son again and smiled. 

	"Tell me.  Are you close to climaxing again?"  Splinter asked him, growling at his anal ring stretched to his needs.  	
	"Oh, no, Master," Leo answered.  "My first climax took a lot out of me.  We can still more things before I peak again, if you wish."

	Oh, yes, my darling.  We have so much more to do.  What we are about to do, you will most likely to find it very pleasurable.  That is why you must fight your orgasm as much as possible.  I want to draw this out with you, Leonardo."  

	Splinter then scooted up all the way until his ass was resting hovering over Leo's crotch.  He reached behind and pulled his son's thumb out of his anus.  

	"Grab my hips, my love."

	Leo complied, slowly realizing what his father had in mind.  He saw that the tip of his erection was mere inches away from Splinter's opening.  He now knew that Splinter had taken great pleasure in having his anus penetrated, and that it was extremely tight inside.  He had just spent a great deal of time loosening his master's tight asshole.  Furthermore, his master had just spent an equal amount of time slicking up his own penis.  This is what he had meant when Splinter had said that they were both ready.  He wanted to place his penis inside of him.  But Leo was worried.  Wouldn't that hurt his father?  Before he could wonder about this anymore, Splinter reached under and grabbed ahold of Leo's pulsing arousal and positioned it so the crown rested against his pucker.  Leo shivered uncontrollably in  anticipation.  He massaged his lover's hips, just like he was asked to do.  His father took a deep breath, and then lowered his hips.  His anal ring immediately parted open, thanks to Leo's work.  Still, he grunted in pain, causing worry in Leonardo.  When just the crown was inside, he reassuringly smiled over his shoulder at his son.  He continued to sink his hips down.  Leo watched in amazement as his dick disappeared into Splinter's body.  His master's tight rectum squeezing his cock was more satisfying than anything else that they did tonight.  He closed his eyes and groaned with pleasure.  He squeezed and massaged the furry hips harder.  Halfway down, Splinter let go of Leo's cock and placed both hands on his son's knees, took a deep breath, and sunk himself down to take the whole of the penis into himself.

	Splinter continued to breath deeply, still adjusting to the feeling of an erection inside of him for the first time since his last trip to the Battle Nexus many years ago.  And to think, the erection belonged to none other than his own eldest son, Leonardo.  He could tell that the boy was struggling to keep his composure, and that he didn't want to hurt his father by bucking his hips.  Splinter rose and fell once to stimulate himself.  Leo's dick was a perfect fit for his anus.  While he was completely imbedded in the rodent's ass, it was still just long enough to gently press into his prostate.  And when he moved, he could feel the tip rub into the gland.  He had to be careful not to clench up.  He didn't want to overload his son just yet.  Leo had said that he was far from another climax, but that was before he had the privilege of penetrating his father's tight body.  Splinter smiled, loving the feeling of Leo's strong hands on his hips and ass.  He couldn't resist tightening up just a little.  His son gasped in response.  Splinter then lifted his hips up, relishing the sensation of Leo's erection grinding against the walls of his asshole.  He felt the hands on his hips react as well, as they were shaking uncontrollably.  When just the tip was in, he sat back down much faster than before.  Leonardo tightened his grip on Splinter's ass cheeks considerably.  Splinter looked at his beloved son and lover, and then repeated the motion a few more times until his body was used to the intrusion.   He closed his eyes at the feeling of the strong green hands running through his sweat drenched fur, up his somewhat ticklish tummy to gently rub his nipples again.  When he felt he was loose enough, he leaned back down to lay on his son's front.  With his back laying on Leo's chest, and his asshole firmly gripping Leo's cock, he placed his legs on the outside of the turtle's, and turned to kiss his cheek.  Leo wrapped his arms around his father's body, and turned to kiss Splinter on the lips.  Splinter obligingly opened his mouth to let Leo slip his tongue inside.  He wrapped his own arms around Leo's larger, more muscular ones, so that effectively, they were spooning.  Although, it was in a position that Splinter had never tried before with any of his previous Nexus male lovers.  In retrospect, he wondered why.  He was glad, however, that the first person with whom to do it was his own adopted child.

	Leonardo felt his heart beat harder than ever before.  He could feel his lungs expand and contract under the weight of his lover.  He felt Splinter's lush, wet fur bristle against his chest and stomach.  He felt Splinter's thin lips pressing down on his own larger lips.  He felt his master's oral muscle lick into and all around the inside of his mouth.  He felt his father's hand squeeze his hand to his hairy chest.  Just for fun, Leo's hand found a nipple and squeezed, noticing how hard the little bud of flesh was.  With his free hand, the turtle reached down and gripped the rat's pulsing erection, giving the organ a few firm strokes.  He then let his hand run over SPlinter's balls, and then down further, where he felt the spot where his own cock was buried to the balls in the greatest warrior he had ever known.  Above all else, he had felt that.  The feeling of Splinter's rectum clenching the turtle's penis was enough to almost drive Leonardo to another blowout.  To know that his master had loved him enough to allow the turtle to do this touched the young ninja deeply.  Splinter reached up and caressed his lover's cheek, keeping his hips still.  After making out with the young turtle for a few minutes, Splinter pulled his muzzle away and looked at his student's face, smiling softly.  Splinter spoke to his lover.

	"Are you still far away from your second orgasm?"  He asked his son, who nodded in reply.  "We can stay locked like this as long as you wish.  I want you to enjoy being inside of me as much as you can.  I  know I am enjoying it.  You feel much bigger inside of me, my darling.  When you are ready, you may--ah!"  
	
	Splinter was cut off as he felt the young warrior buck his hips into his own ass.  The rat squeezed his eyes shut as he groaned in pleasure at the joyous feeling of his prostate being pressed into.  Finally, his boy was beginning to take control like a man.  He laughed as Leonardo buried his beak into Splinter's neck fur and inhaled.  The old master's scent drove Leo wild with lust.  It was so strong, so intoxicating.  He pulled his beak away long enough to speak.

	"Oh, Father.  I'm more than ready," he growled, kissing and licking his lover's cheek.  "You feel so good, my love."  

	Splinter felt warm with pride at being called "my love".  Leo was indeed taking to their mating with gusto.  Splinter moved his hips back and forth to encourage his lover to thrust more, and it worked.  Leo got the idea, and humped his father's butt.  Splinter simply laid back and relaxed, reveling in his son's cock plunging in and out of his rectum.  There were so many things to enjoy.  Leo's mouth trailing sensual kisses, licks and even playful bites up and down the rodent's neck.  Leo's hand roaming over his tight, furry body, across his chest, over his ticklish spots on the side of his tummy, while the other hand massaged Splinter's rigid cock and bouncing balls.  And then there was Leo's own genitals.  Leo's cock was thrusting rabidly into the rat's tail hole fast enough to slap their testicles together.  While Splinter enjoyed the mating, he was getting sore back there, and he didn't want Leo to finish too soon.  He gently placed his hands on Leo's hips and held them still.  Leo let a noise of surprise escape his throat and stopping his movements completely.  He opened his eyes and looked at his father questioningly, while his cock was still stuck in four inches.  Splinter looked at him for half a second before giving a hearty lick to the lad's beak, and he started to move his hips at a more tolerable pace.  He knew Leo was always a quick learner, so he was not surprised when he felt his son match his rhythm.  Moaning in delight, Leo snaked his tongue out to meet the rat's own eager oral muscle.  Their tongues danced and wound together, just outside of their mouth.  Splinter tensed up a bit as he felt two stubby digits pinch his nipple.  In his passion, he shoved his face force and covered his son's beak with his muzzle.  In response, he felt Leo's hand tighten it's grip on his private parts, mainly on his painfully hard penis.  He had already come once.  He wanted much more than just the feeling of a mouth on his dick again.  He could barely imagine how good Leonardo's tight, virgin anus would feel clenching and pulling on his member.  His son would squeal and squirm and make the most delightful, entertaining expressions as his father pushed--

	The old rat was suddenly snapped from his fantasy as Leo, without warning, stopped his thrusting and pulled himself out of his father's tail hole.  Splinter didn't know what his eldest was up to, but he trusted his son enough to not protest.  He wanted to see what his new lover would do.  He turned at stared into the turtle's eyes, which were burning with sexual desire and energy.  Then, without a word, Splinter was suddenly flipped over so that once more, he was laying down on Leo's front, now facing his pupil.  He soon got the idea and straddle the young warrior's lap, and backed his ass up so that Leo's cock was was pressing into his asshole.  Before lowering himself, he bent down and kissed his son.  

	Leo was done being hesitant.  He pressed his beak hard against his father's mouth.    He wanted to know that he could lead as well, and lead he certainly would.  He felt his sexual high drop down slightly at the feeling of his cock in the cold air.  He wanted to go back into his father, and soon.  But for now, he simply enjoyed the feeling of Splinter's furry body against his hard shell.  His penis was resting in the cleft of his master's muscled rump.  He reached down to finger the loose and well used anus with one hand, while the other hand pulled Splinter's head hard into the kiss.  Splinter seemed to be as eager to renew their rutting as he was, so Leo reached for his dick and positioned it at his father's rear entrance.  He gasped into his father's mouth as he felt his member once more become enveloped in tight heat.  On instinct, he thrust his hips up to meet his lover's butt, and broke the kiss to cry out at the feeling of Splinter's anal ring squeezing the very base of his shaft.  He opened his eyes slightly to examine the rat's expression.  The rat had a look of mixed pleasure and pain on his face.  Leo reached up and gently reached up and stroked Splinter's handsome face, making sure never to break the rhythm of his hips.  He failed, however, as he realized that his time inside his master was coming to an end.  He could already feel the fire building in his loins.  He was going to cum soon, and he was going to put his seed right into his father's colon.  He sped up his thrusting, while slightly amused at seeing Splinter making faces he never thought he'd see on his sensei.  Splinter had his eyes shut and his mouth open in pleasure, and he was actually squeaking, to a certain degree.   The teenage turtle couldn't help but smile a little bit at this, and he reached up to pinch a nipple under brown fur.  Splinter must have sensed his son's impending orgasm, for he, too, sped up his rocking on Leo's cock.  This exquisite friction, added to the sensation of Splinter's own member grinding up and down on his stomach finally pushed Leo over.  He reached up, grabbed Splinter under both arms and around his back, and pulled him tight against his shell.  Splinter, in turn, wrapped his arms around Leo's shoulders and buried his muzzle in his boy's neck.  Both lovers cried out and squeezed each other hard as turtle seed shot deep into the rat's ass.  Leonardo made sure his dick was buried to his balls in his master when he came.  

	And come he did.  Far too long had it been since Splinter felt the joy of another male shooting his semen into his ass.  He couldn't think of any better person from whom to receive this pleasure than his eldest student.    He had to focus in order not to wake his other three sons with his cries of ecstasy.  More importantly, he had to focus not to waste his own seed on Leonardo's belly.  He still wanted very badly to mount the young turtle.  Fortunately, years of physical training and self discipline over his bodily urges helped him retain his impending orgasm.  Splinter was able to hold his fire, for the time being.  In the meantime, he simply tightened his anus around his son's penis, and reveled in his orgasm.  Fir the first time since he'd been at the Nexus, The rat felt the hot, gooey sensation of his rectal cavity being flooded with another man's cum.  He picked his head up and shoved his mouth hard onto his lover's.  He licked all around the inside of Leonardo's mouth and he continued to rock his hips on the turtle's crotch, wanting to milk the load of each and every last drop of seed.  Finally, he could tell that his son was running out of ammo.  Leo's orgasm began to fade, and eventually, he stopped coming all together. 

	For a few moments, master and student simply laid together in the sweaty sheets.  Splinter kissed Leo deeply as the young turtle ran his fingers through his father's damp fur.  Leo was breathing heavily though his nose, as his mouth was busy with his partner's.  He could feel his penis slowly deflate and slip out of Splinter's ass.  Twice in one night.  He was done, but he knew his father wasn't.  Along with the old rat's tongue licking under his own, Leonardo could still feel an aching erection pressing against his tummy.  And he seriously doubted Splinter wanted another blow job.  Leo knew what he had to do.  Which was fine by him, as it was only fair to serve Splinter in that way, after all the rat had done for him tonight.  This was confirmed when he felt something thin yet insistent squirm its way into his asshole.  Leo opened his legs obligingly and moaned  into his father's muzzle.  They stay that way for a minute, with Splinter's tongue and tail penetrating his son at opposite ends of his body.  Like his father, Leo kept a clean diet, and there was no worry for any….unpleasantries.  

	Finally, Splinter disengaged the kiss and looked down at his student.  After 18 years, he had learned to read his sons' expressions, and he knew that Leo was expecting his father to mount him.  This was confirmed when Leo reached forth and took Splinter's member in his hand, which was dripping with pre-cum, and spread the sticky, slick substance up and down his father's cock.  Splinter threw his head back and groaned in appreciation, thrusting his hips into his son's grip.  At the same time, he felt his tail bottom out inside his son.  He twitched his tail in order to do his best to erect his son's cock again, but to no avail.  He could that Leo was finished for the night.  Which was fine by him.  Splinter had only came once thus far, and Leo had already had two orgasms.  It was time for the old rat to get his.  He rose up off of his students shell and pulled his tail out.  After seating himself at Leo's feet, he picked the boy's hips up and turned him over, so that Leo was on his stomach now.  He raised up Leo's ass so the he was on his hands and knees, and in a perfectly vulnerable position for his father.  Splinter placed his hands on his student's buttocks, and without any further wait, began to lick Leo's asshole.  Once more he was grateful of Leo's careful and healthy diet. 

	.Leo gasped the feeling of something small, soft, squirmy and slippery knocking at his back door.  He closed his eyes and relaxed, enjoying his position of sheer vulnerability to his father.  He thought he was going to become erect again, but he didn't, and he was completely spent for the night.  He simply buried his head into his pillow and allowed his father to prep his body for one last act of passion.  The sensations he father was giving him were amazing, and he hoped that he was able to please Splinter just as much when the rat had sat on his face earlier.  Leo wiggled his hips in his father's grip and he felt Splinter dig deeper and more aggressively into his backside with his oral muscle.  He could also feel Splinter's rapid, impatient breath blowing into his backside.  The warm air from the old rat's nostrils on his wet ass and balls was amazing, and he thought he just might rise again until the licking and blowing stopped suddenly.  Leo then felt a wet, furry finger press into his buttonhole, and he forced himself to relax.  Splinter saw this, and he pushed his digit into his son as deep as it would go.  The hairy finger felt just as good as it did when Splinter was blowing Leo earlier in the night, though it was coming in at a different angle, so it felt a little different of course.  What he hadn't done before was push an extra finger inside, which Splinter was doing now.  Leo gasped out loud at the extra intrusion, but figured it was necessary to prepare him for what was surely to be next.  Leo felt the fingers thrust and squirm inside him in every direction before Splinter pulled them out and gently place a kiss on both of his buttocks and slightly open anus.  He then felt Splinter place his hands on his ass.  He looked back and saw that Splinter had pulled away from his rump and risen up on his knees.  Leo felt something hard and eager poke at his anus, and he knew what time it was.  He took a deep breath, and tried to relax as much as possible.  Once again, his father was able to read his body language, and he gently thrust his hips forward to drive the tip of his cock into his pupil.  Leo squeezed his eyes shut at the thrill of his father penetrating him in so intimately a way.  

	Splinter paused after his initial mounting of his son.  He didn't want to harm his son any more that it should have hurt.  Fortunately, the tail and finger fucking had loosened Leo up enough so that it was nothing more than a mild irritant.  Splinter could tell that Leo was relaxed enough to start thrusting. Having done this before, albeit many years ago, Splinter had no problem picking a comfortable rhythm for them both, going in a little deeper each time.  Soon, he had bottomed out inside his student, and he paused and relaxed at the feeling of being balls deep in Leo's ass.  Even better, Splinter could feel the tip of his dick press against the turtle's prostate, and he pushed his hips forward just a little bit to stimulate his son.  After relishing the feel of Leo's hips on his crotch, Splinter figured it was time to show the boy real pleasure.  He puled all the way out and shoved himself right back in to the hilt, picking up a steady rhythm he knew the lad could handle.  	Back and forth, he moved his hips, hilting himself each time.  And each time, Leo let out a small moan that was music to Splinter's ears.  Not only that, but he could feel the boy willingly tighten up in order to please his master.  Leo truly had mastered his own pain.  

	Leonardo had been studying ninjutsu since he could read and walk.  And one of the main lessons his father had taught him was to deal with physical pain.  And dealing with it he was.  A dedicated student, he quickly learned to focus and fight his way through the worse pain.  And even though he enjoyed getting butt fucked by his father and master, it did sting just a little bit.  But it was nothing he couldn't handle.  He even tightened up his sphincter just to challenge himself and please Splinter.  And Splinter was indeed pleased.  Leo looked back over his shoulder to see Splinter's face, which was a mask of pure bliss and joy.  Leo was so happy to see the old rat enjoy himself as much as the young turtle had throughout the night.  Leo's body rocked forward with every time Splinter thrust his hips into his son's butt.  And Splinter had even begun to moan in time with Leo's own grunts of pleasure.  He intensely enjoys Splinter's hands as they squeezed and kneaded his scaly ass.  And that's where those furry hands stayed.  They both knew that Leo was done for the night as far as orgasms went.  Splinter wasn't going to push his son's body that far.  But Leo could tell that what Splinter was going to do was to finish this wonderful night once and for all.

	Splinter could already feel his peak slowly rising in his loins.  Leonardo's controlled squeezing of his cock, along with the sounds he was making, were about to drive him over the edge one final time for the night.  He tried to maintain his rhythm, but his body demanded otherwise.  It was time to finish this.  And he couldn't wait to cum inside of his star pupil as hard as he could.  And from what he could tell, Leo wanted the same thing, and he wan't going to let the boy down.  Not worried about whether or not he was hitting the prostate, Splinter powered up his thrusting, confident in his son's pain tolerance.  All the way in, and all the way out, he fucked Leo.  His fire was was coming faster and faster.  He himself had to concentrate not to moan too loud.  But other than that, losing control never felt so good.  It felt almost as good as finally letting go and cumming hard into Leo's clenching asshole.  Wanting to make sure that the young turtle got the full load, Splinter gave three last thrusts into Leo's ass.  

	Leonardo beamed with joy at the sensation of his guts filling up with his master's seed.  He hoped that Splinter felt just as good when he had came inside the old rat earlier.  Leo didn't even need a third orgasm to make this feel special.  Simply having his father take him like this was enough.  He looked back at his father, only to see his furry face coming at him over his shell.  Before he knew it, his lips were pressed against Splinter's, and the old rat as pressing his tongue against the turtle's closed teeth.  Leo happily obliged, and allowed Splinter slip his tongue inside.  While Splinter's orgasm was fading, Leo continued to make out with him.  Leo could even feel some of the sticky seed seep out of his body and onto the bed sheets.  Finally, The old rat's orgasm subsided, and Leo gasped as Splinter slipped himself out of his son, done for the night.  However, neither of them broke the kiss, as they rolled over onto their sides facing each other, caressing the other's face.  After a minute, Splinter pulled out of the kiss and smiled gently at his son.

	"Now, Leonardo, this lesson in male love is complete," said Splinter.  "But please, do not think that his will be our only time.  If at anytime you are ready for another session such as this one, come to me, and if I am ready as well, we will begin."

	An open door policy for sex?  Leo liked the sound of that.  "I will, Master Splinter.  I really had fun tonight."  Leonardo ran his fingers gently though Splinter's chest fur.  "But what about the others?  Will you go to them, as well?  

	Splinter smiled.  Leonardo had always made sure that his brothers were treated equally by their father, not ever wanting any special treatment.  Splinter had always deeply admired the young turtle for this.

	"In time, yes.  When I feel that they need this, and when they are ready," Splinter replied, returning Leo's affections and scratching his shell.  "And you can go to them as well.  If you see they they are in need of guidance with their bodies, teach them what I have taught you tonight."

	"But what if they don't accept this as willingly as I did tonight?  Donnie might, maybe even Mike, but Raph?  He might not like this.  He never lets anyone get close to him."

	"I will deal with Raphael, my son.  But or now, let us rest," Splinter said, pulling the covers up over them both.  By now, he was sure Leo was tired enough to simply nod off and go to sleep.  He kissed his son on the lips, then the forehead, and told him to go to sleep.  Leo did so in a matter of minutes, and soon, Splintered followed, more than happy to sleep in his son's strong arms.
