>Be anon
>Hanging out with Twilight one day.
>Answering questions about humans.
>And finally the question comes up.
>"How do you humans reproduce?"
"Well uh...."
>You manage to stammer out as the purple unicorn stared at you in anticipation.
"Well, the males, meaning me would take our penis and thrust into a female's vagina until we ejaculate."
"That would impregnate the females."
>"Penis?"
>"Vagina?"
>She furrowed her brow.
"Oh man, I've my work cut out for me."
>You then proceed to info dump everything you knew about human mating and reproduction on the inquisitive mare.
>"And you do this for fun sometimes?"
"Well, yeah I guess some people do."
"But others take it more seriously."
>"Why is that?"
"Its a form of intimacy and affection that you only share with one person."
>Twilight was confused by this.
>You had learned by now that ponies here don't have genitals and don't sex it up.
>So the thought of you having "fun" with just one person.... or pony confused her.
>"So why don't you do it with me?"
"What?"
"Uh erm."
>You looked at the cute, doe eyed mare with anticipation.
>"Do you not like me?"
"Well Twilight, like I said it usually between two people who are intimate."
>"Well I really care for you as a friend and I can't get pregnant or anything like that."
>"And you said it can hurt when you get aroused and your penis gets hard."
"Well yeah, but...."
>The thought of you doing lewd things with the mare soon overcame your mind.
"Sure I guess."
>"Oh that's great!"
>"How do we start?"
"Well I'm not hard yet so I need to stimulate my penis."
>"Oh fascinating!"
>"Can I see it?"
>You proceed to nonchalantly drop your pants and underwear to reveal your flaccid dong to the mare.
>Twilight uses her telekinesis to pick up your phallus by the tip.
"Oh fuck!"
>"Oh sorry!"
>"Just wanted to examine it." Twilight says with a scientific curiosity.
>She slides back your foreskin revealing your tip.
>"Fascinating!"
>"And the semen comes from this hole?"
>She says stretching it ever so slightly.
"Uh yeah!" you manage to say while chewing on your lip.
>Throughout Twilight's fondling your blood began to pump and fill your cock to standing.
>"Oh I must have gotten you aroused!" she said with a blush and some pride.
>"So what do we do now?"
"Well, now is when I would penetrate you."
"But since you don't have the tools I'll have to improvise."
>"How so?"
"Let's get on your bed first."
>"Okay" Twilight said with her trademarked inquisitive excitement.
>You two waste no time in getting onto the bed.
"Can you present your rear to me?" You say with eagerness in your voice.
>Twilight turns around presenting her fat purple butt to you.
>Its stuffed with years of hayburger fat and cultivated by thousands of hours of being used to prop up the mare's book reading sessions.
>She smells like lavender and old books.
>You couldn't be more ready.
>You take your hands and grab her flanks, one in each hand, and with plenty of plot to spare.
>Twilight lets out an eep as you pull her backside under your throbbing cock.
>"Anon what are you doing."
"Well Twilight, we call this hotdogging."
>"Hotdogging?"
>You proceed to slide your member between her fat butt cheeks.
>"Oh I get it." She says as she lets out a giggle.
>datass.jpg
>She had just enough frothy mare sweat to use as lube.
>You proceed to move her fat ass up and down until she gets the rhythm and does it of her own accord.
>Ohmygod
>Her purple pillows engulf your dong as you enter a period of ecstasy.
"Fuck Twilight that's fucking great."
>She smirks as she continues the motions.
>Your member is covered in mare sweat and plush buttocks.
>You begin to massage Twilight's backside as a means of compensation for her pleasuring.
>"Ah!" she gasps.
"You like that?"
>"Yeah, don't stop."
>Twilight was now panting and grunting, her soft moans were interspaced by quick breaths.
>You were getting closer and closer.
>You nearly bit off your lip as you rode the waves of pleasure.
>What put you over the edge was her neat fleshy dock.
>It had instinctively raised her tail to grant you access and its twitching in pleasure set off something primal in you.
>You shot a hot torrent of cum all over Twilight's ample behind, some of it reaching her lower back.
>Her plump cheeks caught most of it.
>And as you pulled out a light stream of semen oozed from between them.
>Twilight let out a gasp as the hot cum coated her backside.
>After the orgasm you laid beside the soft unicorn.
>You were still reeling but she had so many questions.
>"How did it feel?"
>"Is the semen edible?"
>"Why is it so sticky?"
>"Did I do a good job?"
>You then grabbed the mare and snuggled her close.
>"Oh is this post coital bonding?"
>"I have a theory about human mating habits and that after the climax you-"
>Twilight continued on with her discussion as you enjoyed the company of a soft, fluffy, and loving mare.
