“Oh. Hello Anon.” Fluttershy looked round and smiled as you entered her cottage. You smiled and waved. From your angle you had a full view of her plot. While there were no holes to speak of, the sight of her exposed ass was incredibly arousing.

“Are you here about what we discussed last week?” You nodded. Today was the day you taught her about human Sexuality. Pinkie had told the whole of town about what you and her had done. It had become quite the hassle as nowadays all you heard was stuff like, “Is it true you have a snake hidden in your pants?” or “Pinkie told me what you did, can you teach me."

Today was your first appointment, your evenings were booked for the rest of the week.

Fluttershy hadn’t been the first to ask, but she'd had the best reason. Her interest was purely academic. Being an animal lover, she was ecstatic to learn about the biology of a brand new species, and you’d decided; if you’re gonna be horny, might as well use it for a good cause. This curiosity seemed to have overridden her usual shy nature, as she’d been unusually confident and forward these past few days.

“Well then. Let’s get started.” She walked to her table and picked up a note pad and a pencil. You wondered how she was gonna write with hooves and no horn, but you pushed these thoughts from your mind as she beckoned for you to follow her upstairs.

“Please remove your pants.” You complied. Pulling down your pants, your cock was released from it’s prison. As she saw your member, already hard, her eyes widened. “Oh my.” She tentatively reached out a hoof and poked it, hearing you gasp she withdrew her hoof, “I’m sorry, did I hurt you?” You shook your head and explained that it felt good. “Oh.” She took the pencil on her mouth and began to scribble some notes.

You moved to sit on her bed and spread your legs.

She put the pencil down and trotted to the bed. “So. What do we do?” you told her that you were going to teach her about something called a blowjob. After explaining what a blowjob entailed, Fluttershy looked a bit reluctant. “If I weren’t using this for my research, I wouldn’t even consider this but...” She seemed to be convincing herself. You told her that is she’s uncomfortable she didn’t have to do it, but she cut you off, “’no, I need to do this.”

She got into position over your cock and dropped her mouth onto it. You could tell she was inexperienced. She began to lick at the tip. You shuddered. Sensing that she was doing something right, she began to suck.

You reached your hands round and cupped her rear in your hands. You massaged her cutie marks as she continued her work.

A few minutes pass and you feel it building up, you told her that it was about to happen and she pulled away. Her jaw dropped as she saw your seed erupting.

“Is this sperm. I need to collect samples.” You told her Twilight already had plenty of samples, and was examining it. “I’ll have to ask her to send me her research.”

She sat up “Now", she motioned to the mess at your crotch, “What do we do about this?” You told her that it could wait. You instructed her to switch places, present her rear and raise her tail. Now the real fun begins.

The sight was beautiful. Her plump yellow cheeks, that smooth valley nestled between them. You'd already nutted, but Anon jr was clearly ready for round 2 .
You decided to start slow. You poked at her rump and were surprised to hear a gasp. You looked up confused to see her looking back, blushing. Pinkie hadn’t reacted at all.

You told her this. Realising what you meant she let out an “ah.”

“Some ponies have a part of their body that feels good for them when touched. Mine is my rump. Pinkie's is behind her ears. Others, like Derpy, aren’t really sensitive anywhere.” Her voice took on a sympathetic tone. “I feel bad for them, they don’t know what they’re missing.”
Derpy was actually booked in for tomorrow evening so it was interesting to know this.

You told her you were going to continue. She gave a nod and your brought your face to her rump. You planted a kiss at the base of her tail. Hearing her gasps was a welcome accompaniment. You moved the second stage. Keeping your head still you began to lap at the smooth skin, Fluttershy began to moan.

Your tongue glided across her plot, “Yes. That’s *gasp* the spot.” Fluttershy was panting at this point. You reached round and took her flanks in hand. You started giving hard squeezes to her cheeks the soft flesh molding to your touch.

After a few minutes, you pulled away, and looked over to Fluttershy’s face. She had tongue out and was panting. “Please *pant* don’t *pant* stop.”

You didn’t need to be told twice.

You inserted your member between her cheeks and began to thrust. As your cock slid across her rear, she practically screamed in pure euphoria. The sound of her moans were a nice change from Pinkie’s indifference. It felt good knowing the pleasure was felt on both ends.

Your thrusts became faster and Fluttershy’s moans became louder. Eventually you felt the second eruption coming.

You tell her it’s about to be a second Pompeii in here. Before she could ask what I meant, you burst into her canyon. Fluttershy’s body spasmed as she let out her loudest moan yet.

“That *pant* was amazing.” You couldn’t help the self-satisfied smile that crept onto your face. “Though....” You began to get worried but then you saw her half lidded eyes looking back, her rear raised again, “....I seem to be a bit dirty, could you clean me up?”

You’d learnt your lesson from the Pinkie experience and had come prepared. You turned to your bag and pulled out a cloth and a spray bottle full of water. You got to work, her moans were a nice background noise to your cleaning.

After a few minutes you could see your reflection in the surface of her ass. You thought how strange that was but you chalked it up to cartoon logic.

After putting away your cleaning supplies, Fluttershy turned to you and sat herself down next to you. “So Anon”, you motioned for her to continue. “What’s Pompeii?”
