"I'm going to murder you once I get out" a green unicorn said, who just happen to be tie from a rope by the her two front hooves. She is struggling to break free since a blue pegasus is licking her horn, which is making her feel all tingly inside. However to understand on what's happening in this story, we must go back a couple of minutes, to get know who these ponies are, and instead of writing an actual beginning we're going to start like this, in the most non-cliche way ever deal with it.
The blue pegasus is, Aerial Ace. She is the best flier in Ponyville and is not related to Rainbow Dash in anyway possible. Just because Ace is a pegasus and is fast, doesn't mean she Rainbow's foal but she is a tomboy, I'll tell you that. Anyways she's was flying around Ponyville until she overheard a farmer pony, who was talking to the newest pony who came live to Ponyville, Rarity. Ace got closer to Rarity and the apple farmer who's name is Apple Eden in their conversion.
"So can I ask something?" Eden ask.
"Anything" Rarity said.
"So I met your daughter the other day and I was wondering..." Eden suddenly trails off.
"Wondering about what, dear?" Rarity ask bringing Eden back to the question.
"Your daughter, Sparity she reminds me umm... your body."
"I'm sorry?"
"Remember when we first met and I thought you were a ghost?"
"Yeah but I don't see why-" Rarity then just realize what Apple Eden was talking about. "-Umm yes you see, Sparity is the actual Nightmare of me."
Ace back off of the conversation and thought "Sparity is actually nightmare Rarity. No wonder she's so interesting but I need to be the top pony which means I have to show her who's boss by having my way her" Ace went flying to find her the unlucky pony. It didn't take long to find Sparity, a green unicorn hybrid. "HEY, SPARITY!" Ace shouted.
Sparity jumped by Ace's shout and it just so happens that she was right under a tree. Like a frighten cat she clung on to a tree branch. "Oh it's just you" Sparity said as she tries to get down. "Why are you shouting anyways?"
"Oh umm-" Ace was nervous. She might only have one shot at this before Sparity knows what's happening "-I found this good book and I thought you might want to see it."
"If it's Fifty Shades of Hay then no thanks, I already read that fifty times."
"No its... wait you read a book fifty times?"
"Yeah well... I kind of wanted to know why that book became a thing."
"But I thought you live in the wild with your parents. How on Equestria did you know it became a thing?"
"I may or may not snuck into cities to read some books."
"You sure you're not Twilight's foal" Ace said with a grin
"Well I am Spike's foal, maybe it came from him" Sparity said with a giggle.
"Maybe, but anyways you wanted to see this book."
"Yeah sure, whatever."
So they head to Ace's place, lucky for her it was nearby and nopony was close by. "The book is in the basement" Ace said, pointing her down the stairs. "Go ahead I'm going to grab something" she then went into her room to grab a rope. She then went down to find Sparity still searching for that book.
"Couldn't you clean this place... what's with the rope?" Sparity asked and before she knew, she gets ropes in a trap. She try to cast a spell but Ace quickly stop it licking it. "I'm going to murder you once I get out" she said struggling to become free. Sparity is also one of those mares that, once you fuck with them you're fuck, the only problem is Sparity sucks at it. She trys to get lose until Ace's hoof started rubbing her marehood. "Why are you doing this?" Sparity mange to say between her moans.
"Because I do this to everypony" Ace said still licking Sparity's horn.
"Yeah... right."
Ace stop licking Sparity's horn and face her. "No really, I rape Surprise, Eden..." Ace trail off in naming the mares she may or may not raped. Ace is now distracted time to teleport, only problem is her horn felt a little funny, probably when she crash into her a few days ago. She try to cast any spell and a laser shot at Ace knotting her back, it must have been a magic surge to sent her back
"Whoops" Sparity not caring as much. She started untying the rope until she notice some was growing near Ace's marehood. She then realize what it is and panic to untie herself before Ace wakes up. Of course since she is panicking it just got worse and worse, it also didn't help she is dripping as well.
Ace soon awoke to see her toy is trying to escape but before she went and stop Sparity, she notice some extra weight has been added to her. She look down to see her marehood has turn into her stallionhood. It's also a lot bigger then what she expect a normal stallion penis to be like. Her's is like a size of a filly's hoof and long as half of her tail. "Oh, Sparity never thought you're so kind to me."
Sparity froze when she heard Ace's voice, and in mind is NOPE! "I'm not ready for this Ace" Sparity said, trying to talk her way out of this.
"You're marehood disagrees with you" Ace said making Sparity wonder why.
"Oh of course I get my mother's lust" Sparity thought. "Now let's be-" she was cut of by Ace shoving her entire dick into Sparity's mouth. Knowing the she been defeated, she starts sucking Ace's dick, not like she had a choice anyhow. Being tie and barely left any room to actual suck but to her surprise Ace came just like that but it didn't help that there is a lot of semen. "I see why you're also call the fastest pony there is" Sparity mock while spitting the rest of Ace's semen out.
"Well oh yeah, I can still keep going" Ace said shoving most of her member in Sparity's marehood.
"AHHHhhh-" Sparity scream in pain "-first you lie to me and then you steal my virginity, what else do you want?" Sparity cry in pain.
"Don't worry-" Ace moves closer to Sparity "-it's my first too" Ace said with a cocky grin
"What but you said...hmppphh-" Sparity was suddenly kiss by Ace. She quickly broke off "-Jerk that was my first."
"Yeah so it's was my too and I glad I had it with a nightmare pony" Ace said taking out her member.
"But I'm no nightmare pony" Sparity said in disbelief.
"What don't you trust me?" Ace said with a smug face on her.
"Yeah because I totally trust a lier and a pony who just rape me" Sparity sarcastically said.
"Don't worry I'm not done" Ace said aiming her member at Sparity's another hole.
"Wait what are you-... Kyah!" Sparity scream in pain. "T-t-take it out! You're going to tear me a part" Sparity said as Ace lunge her stallionhood in her.
"Don't worry I'm the faster pony there is but it's going to be the longest time of your life" Ace said and she wasn't kidding. She might have came faster then Sparity but the amount of times she came made it last for hours. In and out, in and out, it's amazing that Ace has a lot of stamina. It could make any stallions sad. Ace let her semen go everywhere since she had to take it out but once it was done blowing her load, she was ready for another round. Sparity eventually slip out of the ropes by Ace's semen however she didn't want will to leave. Sparity started enjoying after her tenth orgasm and didn't wanted to end, but everypony had to stop some point. Once Ace shot or last load of semen she fell on her back due to exhaustion. "That was fucking awesome" Ace then went and search one of her potions. Once she found one she try and drinking the potion only to by knot out of her hooves. "Hey I needed that" Ace complain.
Suddenly Sparity lunge herself to Ace meeting face to face. "Well thanks to you I won't be sitting anytime soon"
"So what? It's hard to sit anyways."
"Yeah but I like sitting. So to help repay what you done to me I feel we should have some fun" Sparity said charging up her horn.
"What are you-" she was suddenly felt hotter then normal. Ace felt suddenly weak and having the urge to jerk off. "-What have you done to me?" Ace ask as she move her hooves to her normal marehood. She was of course block by Sparity's magic.
"Oh I thought you like the heat from a mating season-" Sparity then cast the spell she accidentally use on Ace. However it is smaller then Ace's stallionhood because it was a magic surge. "-And I'm sure you enjoy our session but why not another. However let's make sure one of us has to goes though hell in the end" Ace is sweating like hell when she just realize what she meant and it's not all she sweat when Sparity lean in to said something more. "I'll be your nightmare."
Inside Ace's house nears the stairs leading to the basement, a nightmare pony and a dragon were spying on the 'couple.' "Uhhh, shouldn't we stop them, Rarity?" the dragon ask his wife.
"Of course not. It's rude to interrupt, Spike" Rarity answer.
"It's also rude to film our foal having sex-" Spike said pointing at the brony camera. "-Also it stinks."
"Trust me, Spike. There's a good reason for it and beside you never complain about the smell after our fifty time when I came back to life."
"Yeah but there isn't a small layer a semen on the floor either."
"You sure? I remember throwing out the blankets every time."
"Fine we won't interrupt them but you're telling her when ever she finds out."
"Very well dear" Rarity said as they watch and record their foal having sex.
