Wedge Foot and Frost Tail watched their teacher trotting along the beach, her hoof-prints forming a neat line in the sand.
The two colts had recently found themselves getting interested in sex.
They had, of course, experimented with one another, but they wanted fillies and mares now.
They really wanted Velvet Love, the porn actress the duo had found, but she was far away in a big city.
Her sister however wasn't.
Her identical sister lived right in town.
Velvet Orchid.
Velvet Orchid the school teacher. Their school teacher.
A young unicorn like her sister, she had only just started to teach.
She specialised in biology, horticulture and magic.
She also help teach the fillies sports.
The two colts watched her shapely flank as she started to canter back along the beach, following her original trail of hoof-prints.

They had discovered the relationship by accident.
While browsing the web for porn the two colts had discovered Velvet Loves old photos and videos.
Really old.
From when she was a filly.
She had a co-star; her identical sister.
The colts had watched in rapt fascination as the two fillies fuck each-other with all kinds of things (sex toys, fruit, vegetables and so much more). They watched as the fillies where rutted by others, getting mounted by a big old stallion (who turned out to be their father), colts their age, all sorts.
They watched as the two young filly's with no cutie marks had grown and earned them.
Just like the sisters, they where identical.
An orchid flower, only partly opened and viewed at an angle.
It looked like a mares sex, the top petal the anal ring, the rest flowing down to look like a winking vulva.

The duo had taken a while to find out the connection between the mare in the pictures and videos and their teacher.
Velvet Love acknowledge the videos where of her.
But only said her sister was the other filly. She never gave a name, and in all their searching they never heard either one called their full name, only Velvet or pet names.
It was only after they happened to be looking at a new photo of Velvet Love on Wedges phone and Miss Orchid had walked by did they notice the similarity.
The problem was, miss Orchid always wore a saddle bag or some other item of clothing over her cutie mark.
The school foals had lots of ideas about why she didn't show her cutie mark. They ranged from absurd (it was some form of strange blob that looked like dirt), that it was simply embarrassing or even offensive, to that she was actually a blank flank.
The two horny colts took it upon themselves to find out.

They stole an invisibility cloak from Frosts father's shop and crept into the teachers changing room, where they hid a tiny camera in a pen they purchased off the internet.
This earned them plenty of dirty footage they enjoyed, but it also scored them the answer to the mystery of what was on her flank.
When they discovered it matched Velvet Loves cutie mark they decided to keep it their secret. They could do so much with this information! (They also realised almost no-one else they knew at school would be interested, a few parents may take issue with a former porn star and relative to one working there and then she'd loose her job and the two colts would loose their chance to do... something)

But first, they wanted to know the answer to another question: Was that actually an orchid on her hip or was it a mares sex? After all, although both had mothers and Frost had an older sister, and there where plenty of girls at school, they never really got all that good a view of a pussy before (at least, one not on a computer screen)
This, again, required invading their teachers privacy.
Velvet Orchid grew orchids in her greenhouse, everyone knew that.
One of the verity she grew as the Teardrop Orchid, sometimes called the Yonic Orchid, which she had, according to an old newspaper article, won an award for years back, but she kept it locked in her private greenhouse.
Using the invisibility cloak the two colts managed to sneak in to the greenhouse and find the orchid.
The flower looked like the spread sex of a mare from their biology books and from their screens!
They where delighted and snapped some photos as extra proof.
They could really use all of this as leverage over their teacher if they needed.

The two colts plotted and planned. So many possibilities.
So many ideas.
It was hard to choose, thankfully they knew what they really wanted: They wanted to fuck the mare in every manner they could think of.

Frost Tail, being a smaller built Pegasus pony, wanted to get the first use of her cunt and asshole. After all, Wedge Hoof was a sturdy earth pony, although his cock was shorter than his winged friends it was much thicker, a blunt tipped solid tube of earth pony stallion-hood. The brown and pink mottle to the flesh log which dropped between his legs mirrored his own fur which was mid brown save a few wisps of pink in his tail, mane and the feathering which covered his sturdy fetlocks.
He was a well built example of an earth pony stallion, fit and strong he liked sports and showing his physical prowess.

Frost Tail, meanwhile, was pale blue with rich midnight blue mane and tail, both of which shimmered like a frosty night. He was lithe and fast, speeding around the sky silently before dropping to surprise his friends and enemies. His cock was longer than his ground bound best friend, but thinner, despite what looked to be an intimidating mushroom like flare to his tip, it was, even at full size, only a little larger than his friends blunt tip when not flared, from there it tapered, widening towards his base with a prominent median ring. The flesh was a mid shade of blue between that of his coat and his tail/mane.

The two colts watched their teachers morning exercises.
Bridle Bay was a big place, a tourist destination mainly, with lots of hotels and inns at one end.
A huge Zeppelin, rail and shipping harbour connections where abundant beyond that, at the far end of the bay and projecting out onto the spit, all passing though the large newly built transit hub.
A stretch of sand and low hills dotted with a few resort golf courses, spas and resort hotels, their town from the port and hotels, providing some separation of the residential and commercial areas, even if it was an hour or two walk from the centre of one to the centre of the other, although almost all traffic was one way - the people of Bridle Bay township would go to work in the transit hubs, ports and hotels, with none of the people arriving heading out into the township (why would they? everything a tourist and traveller needed was in the hubs and hotels, even the beach was long enough to mean incursion was rare)
The touristic and transport hubs meant the town had a large transient population, with many coming off the long distance ships and flights to pass on further into the nation.
The colts were to use this to their favour.
After-all, the locals where all good and nice pony's, crime between residents was so low as to be non-existent.
What crime there was was mostly littering.
However among those transiting and staying in nearby hotels; drunk and disorderly conduct, petty theft where the most common. Sometimes smuggling and trafficking occurred. Only on rare occasions would a rape or murder happen. The perpetrators of the latter two would often either get caught after they moved on inland into another city, or more often than not simply vanish, the government refusing to believe any pony capable of such awful behaviour so some other explanation must exist, most probably they where under some "foreign influence".
Connections to dragon, gryphon and crystal pony heavy lands occasionally brought grudges to the shores of the land, and was often the "foreign influence" the government described - ponies didn't naturally or normally commit violence against one another, however there was plenty of documentation of conflicts elsewhere.

Miss Orchid lived in a small cottage slightly more inland than most of the rest of the town, on the fringes of a golf-course, alone and invisible from the rest of society.
Nice and secluded for the colts plans.
No one would suspect it to be a local if they where cleaver about it, especially if they made it clear how easily they could ruin the mare if she told anyone (even if they believed her).

The evening came.
They had everything they needed and wanted. They had an excess of time.
It was the start of weekend during the school term, she almost never left the house (or at least her garden) from the moment she got home at the end of the week to when she had to leave for work at the start of the next - even breaking her jogging habit, which she did after school.
She got back form her jog as the two colts approached and got into position to wait for the opportune moment.

She was in the garden tending to her plants, Wedge was crouched among the bushes. Frost sat unmoving on the roof, pressed against the chimney with a large old fishing net which they had stolen from the harbour.
She stood directly between Wedge and the door, tending to a pot near it. It was the perfect opportunity
Frost swept down and dropped the net before landing to help the now galloping Wedge.
The muscular colt slammed into the sand coloured mare and sent her tumbling towards the door.
Frost grabbed a rope connected to the net and started to pull her though the door.
The force of Wedges impact has knocked the air from her. She couldn't do anything more then wheeze her protestations.

Slamming the back door with a hoof Wedge watched the beautiful mare struggle.

"What, what do you want?!" She begged the two colts, not comprehending the two colts where from one of her classes, assuming like so many others there where full stallions.

"We've seen your videos and photos Velvet Orchid. You and your sister; Velvet Love. Spreading yourselves, whoring themselves out. You thought you'd be able to leave that all behind." Frost taunted as he pulled out his tablet, a super cut video of the filly sisters debauching themselves playing in explicit detail.
Wedge had managed to yank her saddlebags off, revealing her cutie mark.
The distinct flower red, pink and brown against her sandy fur.
"What... W...Wedge? Frost?! W... Stop this! This isn't funny! I shall tell your ...!" She was cut off as Wedge kicked her hard.
"No you won't. We'll tell everyone about your videos, what you did, used to do. What your sister does. You're identical We can just say you tried to make us do things like those videos, you showed them to us, gave them us. Ponies don't hurt other ponies here, remember misses Crabber how she murdered her husband and had been selling her self and foals to a dragon? Remember how Magistrate said she must have been under the dragons influence, even when confessing? Ponies don't hurt ponies." He taunted, getting close to her.
"But we're gonna hurt you."
