River Tubin'

Twilight Sparkles Family arrived at the local river to beautiful conditions for their annual float.  Her Father unloaded the tubes while her mother tried to slap some sunscreen on Twilight and her brother.  Shining Armor obliged but Twilight was more self conscious about her body and insisted on doing it herself.

Before long all the prep was finished and the family was on the river ready to enjoy the 3 hour float. Shining Armor was especially excited for the two sets of rapids.

It was a peaceful slow stretch for the first mile and Twilights father laid his head back enjoying the tranquility until…

“AAAAAA! I’m sinking. Dad I’m sinking!” It was Twilight.

Sure enough her tube had sprung a leak. There was no way it was going to last the whole float.

It was decided she would have to ride on her dad’s lap since he had the largest tube. It had enough space for the two of them but it was a tight fit.

The float went by uneventfully until they approached the first rapid.  Twilights mother and Shining Armor went first hooting and hollering. Twilight said she had to go to the bathroom first so her father pulled over to the bank.

While she went behind a tree her mother and brother drifted ahead about a hundred yards. Twilight finally loaded back up and they were off.

As she did her father was struck by what a beautiful young filly she was becoming. Her shoulder length purple and pink streaked hair was tied up in a ponytail. Her long slender legs were very shapely and her teats were starting to form into those of more of a full grown mare. Her father caught himself staring and looked away as she sat onto his lap.

The first rapid was the mellowest, but was still bumpier than her father remembered from last year.

Halfway through he started to really feel the bumping from the waves and Twilight on his lap. Mortified, he realized all the friction was causing an erection. Or so he told himself and that it was not the pretty filly that caused it.

They came to the end of the rapid and Twilight's laughter from the excitement subsided. Shining Armor and her mother had drifted further ahead, so they had the section of the river pretty much to themselves. her father shifted around nervously, hoping Twilight wouldn't notice his hard stallionhood. He had no such luck.

“What the heck is that?” she said reaching a hoof beneath her. Her father flinched as she rubbed  his hard cock.

“Oh my god, do you have a boner?”

“Oh, god. I’m sorry sweetie.”, he replied, “Don’t think anything of it, it was just all that bouncing around in the rapids.”

“Eeew, make it go away. It’s totally poking me.”

“I’m trying, hold on.”

He tried to think of innocuous things to turn him off.  Sports, work, his wife’s fat flanks. Nothing was working.

The truth was it had been a long time since he’d had any good sex, Twilights mother had really struggled to lose the weight after Twilights birth, and sitting here with this beautiful filly bouncing around on his stallionhood was turning him on, daughter or not.

“C’mon dad, you’re grossing me out” Twilight said.

“I’m sorry hun, the truth is this probably won’t go down until I cum, er, ejaculate.”

Twilight giggled a little at the vernacular.

“Well do it then and get it over with.” She said.

“I’m not just going to clop  in front of my daughter!” her father said slightly appalled, secretly thinking about it.

“Can’t you just go in the woods?”

“Your mom and Shining Armor are already way ahead of us, we don’t want to lose them.”

“Well just do it then, I can’t sit on that thing. I promise not to look.”

Like it or not they were in a situation that wasn't going away. The longer he avoided it the more awkward it was becoming so at last he decided to get it over with.

“Alright dammit, but don’t tell your mother about this, and don’t watch” he commanded

“Yes, dad” she said sheepishly.

Twilight scooted over so that she was straddling his left hind leg giving him some room. He freed himself and began rubbing it, trying to be quick about it before they caught up to Shining Armor and his wife. In his mind he tried to picture his usual fantasies, but couldn't help stealing glances at the little purple haired filly on his lap.  Finally he caught her peeking down.

“Twili, c’mon you promised.”

“What? How am I not supposed to look? You’re taking forever, and it’s so big… I've never seen one like that.”

“Well I’m sorry, I’m trying this is just a little weird. You are my daughter for Celestias sake.”

“Well we need to hurry before we catch them,” she said, “can I help some way? Do you wanna look at my teats or something?”

“What? Honey I can’t do that.”

“Just pretend they’re someone else’s. You need to get really turned on to ejaculate, right?”

“Well yeah, but, would you be comfortable with that?”

“More comfortable than having your stallionhood jabbing me this whole float.” She said.

Without another word she spread her legs just enough to reveal the most perfect small firm teats he’d ever seen. Daughter or not this was working. Her young nipples were building him closer. He continued for a while but still wasn't there.

“You gotta hurry dad, we’re gaining on them. Try touching them.”

“Honey…”

“No time dad, just do it.”

She took hold of his left hoof and placed it on her teats as she laid back against the tube. her father gasped a little at how firm hey were. Losing himself in the moment he allowed himself to rub the nipples.

“Helping?” she asked.

“Well, yeah actually.” He said, “your teats are amazing. You have become such a beautiful young filly. This is still kinda strange for me though, I don’t know if I can do it.”

“Ugh do I have to do everything?” she said and shockingly reached over and started rubbing his cock.

“Twilight! No honey you can’t!”

“Relax dad, It’s better when someone else does it, right? Just let me take care of it.”

“Oh, my god. Twili, this is wrong, we, we, oooh my god where did you learn to do that little girl?”

“I’m not so little anymore.”

She was working his cock expertly. her father couldn’t remember the last time he had felt like this. His wife had

completely lost interest in sex since Twilight was born but even before that she had always been a cold fish.

Now here was a knockout of a filly rubbing him off and it felt amazing. He was rapidly losing concern that she was his daughter.

She increased her pace, furiously rubbing up and down trying to make him cum while he massaged her teats with both hooves now. He leaned his head back in ecstasy and when he looked up was surprised to see her other hoof down between her own legs.

“What, uh, what are you doing now?” he asked.

“Don’t be mad daddy, this whole thing is kinda turning me on. Girls need to come too sometimes you know. Would that help you cum sooner dad? Watching me cum?”

“Oh my god, I can’t believe this.”

“Maybe if you help me do it, it will help you dad. Let’s help each other.”

She grabbed one of the hooves on her teats and guided it to her waiting pussy and placed his on her exposed mound. It was small and glistening. her father was helpless. He had never seen anything so perfect in his life. He began rubbing in small circles then worked his way up to her clit and then back down to enter her.

Twilight  resumed hoofing him off, using two hooves now. Together they increased the pace building closer and closer to mutual orgasm.

“Oh, oh dad. You are so good at this. I’m gonna cum really soon. Don’t feel bad daddy, I love it. I want this. OOOOhhh. God dad. It’s so good, I’m gonna cum…”

“Yeah baby. You are doing so good. I’m close too honey. Keep going.”

Faster and faster they went not realizing they were coming around a bend in the river.

“There you two are what’s the hold up?” It was Twilights mother. They had caught up.

“Fuck, quit!” her father half whispered. Luckily it was a deep tube so they weren't seen, but still had to scramble.

“We’re up to the big rapid Dad!” Shining Armor shouted

“Er, um. Okay champ, go for it.” her father replied as Twilight re-positioned herself back on his lap. His cock was

throbbing now as her flanks ground on it.

Shining Armor went off into the rapids, Twilights mother followed second. As her father and her descended into them she reached behind herself and rubbed his cock again.

“That’s enough Twili, they’re right there.” her father said.

“Mmm, I can tell you hate it.” She said.

As she stroked him behind her back she scooted down in the tube and spread her hind legs again and began

masturbating again.

“Oh my god honey, we’re gonna get caught. By Celestia your pussy is beautiful though.”

She giggled at this. Up ahead Shining Armor and her mother were hollering their way through the rapids. Their distance increased a little as her father back paddled, but they were still close. Suddenly they hit a particularly large bump that threw Twilight  up higher on to her father’s lap. She squealed with excitement. As she re-positioned this time she reached between her legs to hold his cock. Without warning she straddled him and this time brought the head of his throbbing stallionhood right to her dripping pussy. Before he could protest she rubbed it up and down her slit and then sat down on to it.

“Oh god, Twili, no, we can’t, we, ooooh my god.”

“It’s okay Dad. Oh, Celestia is it ever.”

They reached the largest part of the rapids. her father back paddled to buy them time. The waves bobbed the tube up and down plunging his cock in and out of her without effort from the father and daughter. The sensation was amazing. The natural rhythm of the water was bringing them closer and closer to orgasm. Twilight was moaning louder and louder, scaring her father that the rest of the family would hear.

“You gotta be quiet honey, we’re so close to them.”

“Finish then, Daddy. Fuck me hard. Make me cum.”

All apprehension was lost in their lust. her father grabbed her by the waist and began fucking her furiously. Her small frame was so light he could simply slam her up and down with his forelegs without need of his hips. Faster

and faster he plunged deep inside her.

“Oh god daddy, oh fuck yeah I’m gonna cum. Are you gonna cum with me dad? I want you to cum deep in my pussy.”

“Yeah baby. Daddy’s almost there.”

They caught sight of Twilights mother and Shining Armor around the last bend of the rapid.

“Gosh you two are slow today!” she shouted back. “Are you coming, or what?”

“YEEEAH!! I”MMM CUUUMMMIIINGG!!!” Twilight screamed.

Her father exploded into her. He had never cum so hard. Her pussy clamped on his cock seeming to pull him

into her deeper than ever as he filled her with his seed.

As they reached the bank where Shining Armor and Twilights mother were loading up their tubes into the truck. Twilight and her father quickly rinsed off in the water,  gave each other a loving look, then kissed.

As they pulled their tube out of the water her mother asked, “So how was it sharing the tube, not too tight a fit?”

Twilight smirked and said, “Oh, I think we fit together just right.”
