Experiments of a Lewd Scientist

This is a completely different day, Twilight got a message from Cadance, it said "We have the house for ourselves" Twilight gulped some saliva as she stands outside of the house of her sister in law. She knew Cadance since she used to babysit her and Twilight knew that she tends to act a little strange when it comes to love or similar stuff; still remembers some of the sounds she made on some days she got dates with Shinning Armor at her old place.

"Ok Twilight, you got this!" She said to herself while taking a deep breath. "You know her, she's married with your big brother... it's a natural thing to go visit your sister in law..." Twilight looked at the house for a moment and then walked closer just to ring the bell. "... I should go back and get the recorder for the audio log..."

As soon as she tried to step away, the door opened and Cadance showed. "Twilight, you took your time to come" She joked to the science girl who was obviously really tense. "Come on in" She invited Twilight inside, who walked in with very heavy steps, as she stepped inside she noticed a very intoxicating but lovely smell inside the house; it was strawberry? roses perhaps? All she knew is that the smell made her feel a little more relaxed to the point of closing her eyes and enjoy it.

"My! You didn't had to do this" Twilight expressed with her eyes completely closed enjoying the smell of the perfumes; she was really comfy with that smell, but then Cadance closed the front door and approached Twilight from behind and cared her hands all over the side of her body. "W-wha...? Cadance?"

The principal's hand clunched to Twilight's boobs. "You've been naughty lately, am i right?" Cadance asked to Twilight with a very serene but playful voice.

"This is because of the dildos?" Twilight asked while her body started to feel in heat at the touches of her sister in law.

"Not exactly, you thought that i wouldn't have seen your little stream of the other day?" Cadance stated, sqeezing Twilight's boobs a little harder now. "You in such beautiful white lingerie... and that bush of your slit... you loved being watched by strangers?" Cadance asked once again, Twilight's breathing turned heavier as well a little moan escaped between her lips.

"It was... for the science" Twilight tried to excuse herself, but the hands of her sistr in law were something out of this world; her more experienced time in pleasing really shows, now those conversations with the family where Shinning Armor said that she was like a non-stop truck of love started to make sense. "These hands... are... Ahhh..." Another moan, now interrupted her speaking, with a little move, Cadance hold Twilight by the chinn and looked into her eyes before they shared a passionate and sloppy kiss; both women tongue action was really intense even with the fact that Twilight hasn't kissed anyone before that point.

Cadance leaned her head back before looking into the eyes of the slim scientist girl. "Follow me Twilight, this is meant to be done in the room" She hold Twilight's skirt and lead her to the bedroom, Twilight did not tried to fight back; she was just amazed by te whole self of her sister in law, that kiss felt like a car running towards her brain; shutting down all primarly inhibitions of the body and switching them to pleasure. They reached the bedroom shortly after, the bed looked like a very big marshmallow waiting to be tasted. "Here Twilight, put this on"

Twilight grabbed the clothes Cadance gave to her and checked them, she found out that there were white lingerie with holes in the thong and in the bra for the nipples, both were also accompany by a pair of lace stockings with heart patterns all over them. Twilight proceeded to put them all on, feeling really comfy and the only thing she could be missing would be a pair of elbow gloves to feel like a very rich woman acting like a total slut, but there was indeed something else she didn't noticed, a blindfold.

"Huh... what is this for?" Twilight asked confused by the blindfold, but then Cadance appeared from behind and took it just to place it on top of Twilight's eyes before she could see what Cadance was wearing. "C-Cadance? Where are you?" She moved her hands to try to catch her, she kinda knew that she wouldn't be able to take it off.

Then the scientist hand landed in a soft and squeezy zone, Twilight squeezed it for a moment to try to guess what it was; she got it clear as soon as she did a few more squeezes. It was Cadance's huge breast, compared to Twilight; she were no match for the huge ones her sister in law had. Cadance letted out a soft moan at the touch of those sweet squeezes, that caused Twilight's cheeks to blush intensily red before she got grabbed by the wrist and being layed on top of the soft bed that the room had.

"My my.... you're naughty if you grab someone's breast without permisson" Cadance whispered to Twilight's ear before kissing her neck while also caring the hands on the scientist's cheeks. Twilight felt those touches more intensely, maybe wearing the blindfold made her body feel more sensitive to foreing touches; Cadance's hands felt really playfull, more than she could ever do with herself. "Let's see what you are hiding... here!" She stated before rubbing a finger between Twilight's slit, the fact that the tongue had that overture for fingers to run along it was a really great touch; Twilight only had one question, why does she have lingerie of her size?

"Wait... i am..." Twilight felt how one of Cadance's fingers gor inside of her slit, a loud moaning escaped her mouth before she could finish the sentence. "... sensitive there" she stated to her old babysitter, a big mistake for Twilight to say that to someone that already knows female bodies and their pleasure points. Cadance arched a big smile before continuing to rub her finger inside all over Twilight's inner pussy walls, moaning getting more intense. "I had to say it... didn't i?" she thought to herself, really not the smartest move she could do.

"Don't worry Twily, this is just the beggining!" Cadance whispered into Twilight's ear before putting cuffs on her wrists, while also being tied to the head of the bed, Twilight could hear the sound of something metalic, but couldn't recognize it. Then, she felt something round against her pussy lips, very cold. "It's good to use them with your own hand but... it's better to feel it with a little harder thrusts" Cadance hold Twilight's thighs and then pushed her hips, Twilight now recognized that it was a dildo, a very long one that reached her womb in one go.

Twilight's eyes widen, but it was not possible to tell because of the blindfold; she only felt Cadance moving her hips back and forth constantly hitting her on the entrance of her womb. She couldn't stop moaning, that really was hitting her insides hard but in a very pleasing way. All she could do was just moan and bit her lips while Cadance trhusted her hips with a very consistant hips speed, Twilight wanted to remove the blindfold to see what Cadance was doing and what she was wearing; but it was no possible; unnable to see what was going on her body felt in more heat than before and with her pussy leaking a lot of juices staining the bed sheets underneath her.

Cadance thought that her loud moans could disturb the neighbors, so to keep her shout in silence, she proceeded to kiss Twilight in her lips while also digging her tongue inside of her. The playfull tongue from Cadance was really hard to keep track of; like it has it's own life, it played with Twilight's tongue twirling around and teasing every inch of it, making a saliva mess. Twilight couldn't handle such magnifficent display of pleasing skills, Cadance level was way higher than hers... how long could she hold herself? Well, in fact it was not tood long, Twilight's body shaked shortly after all tose mixed feeling over her body, the dildo, the blindfild and the tongue kiss, Twilight squirted all over Cadance's crotch and bed sheets staining them in all of her juices.

Cadance leaned back, giving her space to catch some air, panting hard. "Twilight, you did a really big mess. You're so naughty"

"And who fault is that?" She asked, a little annoyed because she wanted to see the action.

"All yours Twily" Cadance giggled before pulling the dildo out of her siste in law's pussy. "But you've made a really big mess, so wait here while i take a shower. After that i have to go to a meeting"

"Wait... you can't leave me here just like that!" Twilight demaned to get untied, but no response to be heard. "Cadance?... Hello?" She was left alone in the room, wrist with cuffs and unnable to leave. Well good news are that she won't forget to write a log about being dominated by someone that became part of your family... that's for sure.
