FETISH SEMI-CLOPFIC TIME!
Fluttershy was alone with Spike in her cottage, away from all the other ponies. They were sitting together on the bed, Spike sitting on Fluttershy's lap, keeping her company. He was telling her a story about a knight who saved a princess from an evil sorcerer.
Fluttershy realized that now was the perfect time to do something she was planning on doing for a long time. She wanted to examine Spike, and now she was alone with him. No other pony would have to know.
"Hey, Spike, can you do a favor for me?"
The dragon grinned.
"Sure, what is it?"
Fluttershy blushed as she formulated her request.
"Well, I'm a biologist, and you are a dragon. There is very little information on dragon anatomy, especially on certain areas and with dragon youth. Well, now are with me, and I have a perfect opportunity to gather some data. If you don't mind, I'd like to inspect your..."
Her blush intensified as she gestured towards her crotch.
"...uh, so may I?"
Spike look horrified and turned red himself, but then his look turned devious.
"I will, but only if you promise to let me explore yours as well."
Fluttershy's blushed intensified. To let anyone go down there was a horrify idea to her. She got anxious whenever she saw the doctor for just that reason. However, she was doing the same to him, so it was only fair that he let him do it.
"Alright, I promise I will."
"Okay then. Lets get started!"
Spike lay down on his back and spread his legs. Fluttershy leaned forward and noticed two objects of interest. The first was a slit at the base of his tail. She pried this open with her hooves, revealing a fleshy space with a hole at the top and bottom. Spike leaned in to watch as well.
"This is your clocoa. It's a common feature of reptiles as well as birds. As you should know this is where waste is gathered before it is expelled. "
She then leaned in to examine it closer. Sure enough she saw signs on each hole detailing their function.
"Now, the top hole is the urethra, it connects to your bladder and expels liquid waste. The lower hole is the anus, which connects to the colon and expels solid waste. "
She then closed the clocoa and moved onto the other feature. It was a bump of wrinkled skin with a hole on top. She placed a hoof on either side and started feeling it and examining it.
"This appears to be a penis sheath. Inside is your penis, which you will use when you are older to fertilize lady dragons so her eggs will hatch. Now let me see if I can do something."
She then started rubbing the skin back and forth between her hooves with much energy. Spike began to feel a strange and intense sensation down there.
"Fluttershy, what are you doing?"
Then it happened. A pink bulb emerged from the hole at the top, followed by a shaft which she started to rub.
"And this is your penis. It's coming out now because its full of blood because its aroused. The top is called the glans, it's shaped like that so it gets a better grip on a vagina while mating. I guess a dragon's testicles are inside his body."
She then dropped the penis.
"Okay, it's your turn now. "
She lay down on her back and spread her legs slightly apart, laying her tail back so Spike had a clear view of her nether regions.
"Go ahead, touch it. "
Spike started by placing his hands on an a hole that looked like a star right above the base of her tail. He stuck a claw and finger in, and felt her muscles squeeze it.
"This is so cool. What that?"
Fluttershy stuttered out her response.
"That's my anus. "
Spike hastily pulled his finger out. Fluttershy laughed.
"Mine was just cleaned out an hour ago. You know, the anus is the only voluntary sphincter, let me demonstrate. "
Fluttershy didn't know what was going through her head, but with Spike feeling her up she felt unusually bold and light headed. She strained and flexed her anus, revealing glistening red folds as it opened up. Spike was fascinated and stroked it with a single finger, which made Fluttershy giggle.
He then moved upwards. He skipped over her slit and moved onto two mounds between between her legs. They each had a wrinkly pink part on top. He squeezed them, they were soft but firm, like bags of sand.
"These are my breasts. When I have a foal they will produce milk for him to drink. "
Spike smiled as he played with them.
"I see these on all the other mares, even Twilight. Rarity's are huge. Yours are rather small."
This caused Fluttershy to tuck her head behind her head in shame.
"I'm sorry. They aren't very big, but they are gorgeous. Now what are these?"
He began to fondle the tips. In comparison to the breasts they were somewhat hard.
"Those are my nipples. Foals suck on those to get the milk inside the breasts out. "
Spike then moved on down to the slit. He placed a claw on each side. It was leaking something from inside, which made it quite slippery.
"Twilight never let me touch her here. I did once while she was asleep, but she started stirring once I put a claw in it. Now I finally get to see in side. "
Spike's touch on her felt like a thousand. Fluttershy was getting excited now.
"That's my vulva. Please look inside. "
Fluttershy then spread her legs further, forcing her vulva open and giving Spike a clearer view of what's inside. It was fleshy, pink, and very moist. There were two holes in it, and a knob at the top. Spike put his fingers in the bottom hole. The muscles were tight, but he was able to stretch it.
"That's my vagina. I don't know what Twilight has told you, but the truth is that foals enter the world by passing through a pregnant mare's vagina. The other whole is my urethra. "
"And what's this?"
Spike went on to flick the knob. This caused Fluttershy to squeal.
"That's my clitoris. It gives mares pleasure. Please suck on it!"
Spike bent forward and did as she said. It tasted odd, sort of sour, but he enjoyed it. Fluttershy enjoyed it even more, squealing with delight as she felt the intensity of the sun gather into one point on her body. She was out of her mind and in heaven.
" Wee! Hey, you want to know how you fertilize lady dragons? You stick your penis into her vagina! Try it on me, it will prepare you for Rarity!"
Spike removed his mouth from her clitoris, sat up, grabbed his penis, and carefully aligned it with her gaping vagina. He slowly inserted it inside. Fluttershy screeched.
"Now thrust it in with you hips. "
Spike did as he was instructed. Fluttershy screamed for more and automatically thrusted in response. They continued until Spike felt a rising force inside him.
"Ehhh...I...eh"
"Don't stop now!"
Fluttershy thrust once more and with that Spike exploded. He felt odd as semen gushed out, but it was also the best feeling he ever felt. However, it left him exhausted, and slowed down.
"Keep going! I need my turn. "
So Spike forced himself to continue on. Soon enough Fluttershy felt the familiar fire build up with in her and release. Spike felt her vagina contract rapidly around his penis, and her hip convulsed. At last she stopped and sighed. Soon enough Spike fell asleep, his penis still inside her. Fluttershy lifted him up and cradled him.
"I just fucked a baby dragon. What the fuck is wrong with me?"
The Mother Fucking End
