Twilight thrusts in the still crevice of Libi’s pussy, causing the demon to groan happily. They have been having sex for what feels and most likely is hours, and Twilight feels (and hopes) this is the last load. Libi is bent over with Twilight holding her hands from behind as she thrusts in, Libi’s legs are spread out unable to support herself, twitching every time Twilight thrusts in, making her now huge bloated belly the only thing keeping Libi off the ground, full of gallons of Twilight’s thick cum, trapped behind Twilight’s monsterious dick, making her seem eleven months pregnant with triplets. Libi’s and Twilight’s face are both in states of ecstasy with their tongues sticking out, their hair in messes, and moaning like whores.

“I am gonna cum again!!” moans Twilight, speeding her thrust up, not caring how much her hips are killing her.

“Go ahead!” moans Libi, edging Twilight on, “Fill me up with more cum!!”

Twilight slams her entire length in, and groans as she cums. Libi moans as her belly bloats further, making it now look like quadruplets. Soon Twilight finishes, slumping back and letting go of Libi’s hands, nearly causing Libi to fall on her face. Twilight moans as she weakly pulls the rest of her flaccid member out of Libi’s soaked pussy that is still tightly clinging onto the escaping dick, making a wet pop as it comes out. The cum starts pouring out very fast from the demons pussy, until its lips suddenly closes up, trapping the cum again.

“How did you do that?” Twilight asks, shocked at the sight.

“I have complete control over my body, Mistress,” Libi says, managing to seat up in a kneeling position, holding onto her bloated belly, “I can control any aspect of my body, be it the size of breasts or arse, or how tight my pussy is.” She then puts her hands on her bloated belly and rubs it, “You certainly filled me up?”

“Yeah, I guess I did…” Twilight says, blushing and averting her head away in embarrassment.

“Don’t be embarrassed, Mistress,” Libi giggles, “That was the best fuck I have had in like forever! You had great stamina… but this is a lot of cum to come from those balls.”

Twilight nods, it is weird, her balls are pretty big, but no way big enough to hold this much cum. “I will have to research this later,” she decides, she then looks at Libi’s still very bloated belly, “Are you going to be ok, I mean you’re very bloated and you’ve trapped it in there again?”

Libi smiles and places her hands on the middle of her belly, “Watch this,” she says, applying pressure on her stomach, causing it to get smaller. Twilight watches amazed as her belly shrinks under her hands. No cum pours out of pussy and just seems to disappearing, and very soon her stomach is back to normal. “Thanks for the meal,” she jokes, patting her stomach.

“How did you do that?” Twilight asks, for a second time, “Did you just absorb the cum?”

“Sort of,” Libi explains, scratching her head, “But not in the way you thinking of. Despite what some ponies think we demon’s don’t eat cum, what you saw is a way we remove large amounts of cum without causing a mess.”

“Oh, what do demon’s survive on?” Twilight asks, curious, who actually never heard of the idea that demons feed on cum.

“We don’t survive on anything,” Libi states, standing up and walking to Twilight, standing in front of her, “What we do is get empowered by feeding on a certain thing that can change between demons. Example I am a Demon of Lust, so I feed on Lust…” she leans down and places her finger under Twilight’s chin, lifting it to it is level with Libi’s face, “And I got a lot last night.”

Twilight blushes but she doesn’t turn away from Libi’s face. She never really noticed it before, but Libi face is really beautiful, with long beautiful eyelashes that sit above her mesmerizing red slitted eyes, she has an adorable nose, a very well shaped and totally feminine face, and has a beautiful pair of lips. Twilight has seen quite a few humans during her trips to the human world, but none are as beautiful as Libi. You could almost call her sinfully beautiful. Twilight is surprised she hadn’t noticed before, maybe because it is lighter… wait, lighter?

Twilight tears her eyes away from the tempting demon, to see the sun is starting to raise. They had been having sex all night!!

“Oh no, Spike will be coming home soon from Rarity’s soon!” Twilight says, starting to panic, “I can’t believe we have been having sex all night!”

“I did say your stamina is impressive… in many ways,” Libi teases, unknowing of Twilight's plight.

“I gotta clean myself up before he arrives!” Twilight says, quickly getting up, whimpering as a night time of fucking takes it toll. Her legs are very stiff and sore.

“Oh, let me help,” Libi says, grabbing Twilight’s limb dick, making Twilight gasp.

“Wait, what are you doing?” Twilight yells, as she watches the demon handing her flaccid dick, moving the soft flare near her mouth.

“I am just helping you clean it up,” Libi smiles, moving her lips near her flare, causing Twilight to gasp as she feels Libi’s hot breath blow across it, “And I just saw your naughty dick was leaking the last bit of cum onto the floor so I thought I would get rid of it.” As she finishes she suddenly latches her lips onto Twilight’s flare, sucking it hard. Twilight whimpers as Libi sucks the last of the cum out… it felt amazing. “Delicious,” Libi says, smacking her lips, “You want me to clean up the rest?”

“No thank you!” Twilight quickly says, escaping Libi’s grasps and gathering up her things before quickly leaving the room, leaving a confused demon behind.

Twilight dashes to the bathroom and starts up the shower. She tries to clear her mind while she waits for the water to warm up. She nearly said yes to Libi, for a split second she wanted Libi to lick clean her clean with her long and dexterous tongue. Twilight can imagine Libi running her tongue down her shaft, sucking and licking every inch, until she got down to her balls, Libi would spend ages licking and sucking her balls, savoring it, and then she would go further to her now dripping pussy, she would lick it until Twilight cum so many times, then she would stick her tongue deep into…

Twilight suddenly snaps into reality and realizes that she has began to play with herself, one of her hands has grabbed and begin playing with one of her breasts, and the other has slipped past her dick and is rubbing her sodden pussy. Twilight quickly removes her hands and steps into the shower, letting the warm water wash over her.

“I can’t believe myself,” mutters Twilight, starting to wash herself, “I just had sex for the first time and I am already acting like a horny filly.”

Twilight never really ever thought about sex before, actually until recently the only time sex or anything sexual had been in her life, was accidentally walking into her parent’s room when she was really young, also when she also accidentally walked into Shining Armour’s room and he was sleeping with a mare she didn’t get to see because she managed to hide under the covers, she now guesses that was Cadence. The last time was when she tried to masturbate a while before she came to Ponyville, back when her dick was still small.

So basically Libi was right, Twilight is a virgin in every regard… until now. She is surprised that she was able to do all the things she did, for she knew nothing about sex until last night, beside what sex is for. Babies right… I wonder if demons can get pregnant by ponies? She better ask Libi about this later.

“But why am I acting like this?” Twilight asks herself, confused, “Is it because Libi got me aroused before? That has to be it, she got me aroused and now I just want to relive herself. Yes, that is it, I would never really want Libi to touch my marehood, cause that is out of bounds.”

Twilight has it all worked out, she will get rid of her dick, banish Libi back to the Abyss, find a nice stallion, marry, maybe have a foal, and never have to think about demons or having a dick ever again.

Twilight gets out of the shower and grabs her towel, wrapping it around her chest. She leaves the bathroom and walks to her bedroom. She stops for she sees Libi on the way. She is sitting on a windowsill and looking outside, with a bored expression her face. She notices Twilight standing there and looks her way. She looks Twilight’s body up and down before smiling.

“You look good in towel,” Libi flirts, smiling further as Twilight blushes, she then suddenly sighs, “I envy your figure, Mistress. I wish I was as busty as you.”

“Oh, I wasn’t alway like this, but after I became an alicorn my body sort of became like this… Anyway I thought you said you could control your body?” Twilight asks, confused, “Why not change your body?”

“Because numbnuts, it’s not permanent,” Libi rudely says, frowning, “I could make my breasts as big as watermelons, or my arse as big as a pumpkin, but it won’t be forever. I am stuck like this… unless I gain more power.”

“How would gaining more power let you change your body?” Twilight asks, curious.

“Cause I would become Succubus,” Libi explains, looking annoyed.

“Aren’t you already a Succubus,” Twilight asks, remembering that Succubus are demons of lust.

“No, there are Demons of Lust and then there is Succubi. A Succubus is a very powerful Demon of Lust, causing them become perfect in nearly every regard,” Libi explains, frowning at Twilight ignorance, “Sadly I am not quite there yet.”

“How are they perfect?” Twilight asks, confused again.

“I meant sexually, they gain perfect control over their body, so they can permanently change their body to fit any fetish, also they become very beautiful,” Libi finishes, sighing.

Twilight shakes her head. “I get the body thing but I don’t get how you can become any more beautiful, you are already one of the most beautiful things I have ever seen…” Twilight suddenly went a deep red at the realization at what she is saying, Libi is also blushing too at the very frank compliment. “Excuse me!” Twilight says, dashes off and once again leaving behind a very confused demon.

Twilight dashes into her room, slamming the door behind her.

“Also must be tired too, very tired,” Twilight says to herself, as she quickly dresses herself.
