What's next?
A fun "experiment"
Mark was walking towards the huge building that was connected to the other strange buildings. He opens the door on it, and enters inside. Once he's inside he notice that he was in a pitch black room, he carefully take slow steps not wanting to bump into anything/anyone.
"I hope the sisters are not terrifying." said Mark shruddering, "Hello! Is anyone there?!" called out the lucky SCP, his voice echoing throughout the large room.
He kept on calling for a while, until a bright flash of ligjt surrounded the room forcing him to close his eyes. The light died down and Mark open his eyes and notice the room is no longer pitch black, but rather a nice room.
The walls are colored in pure white, there are a lot of research equipment around the floor and ceiling, and a buch of experiment things, he could've swore that there was a bucket of ice cream in the middle of a table, making him confuse.
"They weren't kidding that these guys love experiments." commented Mark.
"Hello there." said a voice.
Mark turn around and notice three beautiful girls. On the left was a tall young female adult, she has long blonde spiky hair that reaches her back, blue eyes, a white mantle covering her left shoulder, a white uniform with a yellow tie, black pants and black shoes. On the middle was a young female teenager that reaches the shoulder of the female adult, she has short brown hair, red eyes, and wears the same clothing like the other one but has a long gray skirt that reaches down to her ankles. Finally was a young pre teenage girl that reaches the shoulder of the female teenager, she has dark brown hair, black eyes and still wear the same uniform like the other two but instead of a tie it was a yellow ribbon.(Their appearances is based on the Oversimplified SCP manga, but they have colors instead of color gray).
"Woah they're kinda cute and beautiful." said Mark admiring them.
This cause the three of them blush a bit, but quickly vanish.
"So you must SCP 651 or rather Mark, correct?" asked the adult one.
"Yeah, that's my name. How do you gals know me?" asked Mark.
"We heard theres an SCP that has the power of good luck and can nullify any SCPs power." said the teenager one.
"During with our experiments with the personnel of the foundation, we read their minds and heard more about you." said the younger one.
"Oh that kinda makes sense, I guess." said Mark.
"Since your here, wanna be part of our experiment? We have a lot of tests that we want to discover." said the adult one
"And were curious to see, how your ability works." said the teenager one.
Mark began to think about it and remember what the director said to him, about having sex with the three sisters.
"I hope things will not get chaotic when I'm around here, god I hate complications." thought Mark to himself, "Ok then, but this does not involve with any organs opening up, drinking chemicals, or something."
"Oh, it's nothing like that." said the younger girl reassuring him.
This made him sighed in relief.
"Its to measure different the length of the pipes, run through a football field, and finally taste the difference between two different ice cream." explained the adult one.
"Huh? That doesn't sounds bad." said Mark himself, even though the first one sounds hard but he can manage it thanks to his lucky powers.
"Then lets proceed to the experiment." said the teenager one.
The three of them go towards their respective facilities, to prepare the experiment.
"Hey, before we start can you gals tell me your names?" asked Mark.
They turned to back him, and the adult one said, "My name is April."
"May." said the teenager one.
"June." said the younger one.
"Neat."" He then followed May to her experiment room. Soon the experiment started...
Few, experiments have passed...
The Sisters are now in table calmly drinking tea, they enjoyed the experiment with Mark. The lucky SCP however has his face face planted on the floor, and was groaning.
He never would've thought the experiments were ****, first was the pipes he thought it was hard but boy he was wrong, whenever he tried to measure the pipes it keeps on extending where measuring is impossible making him annoyed he thank his lucky ability that it stop the extensions of the pipes and manages to measure it, with May recording the research. Second was the football field, he thought he was gonna play the sport but instead he must run half way across the field with wizards shooting magic fireballs at him, luckily he reach the goal and April recording the experimental data. Finally the last experiment is the weird one, because all he has to do is taste the difference between two ice cream, June keeps on giving him ice cream until he finds the difference, luckily his ability save him and manage to found the different ice cream, making June write it down.
"That was such an enjoyable experiment Mark." said April sipping her tea.
"Agreed, your ability gave out many possibilities." said May agreeing with her sister.
"Not to mention, I manage to succeed with my experiment!" said June happily while eating an ice cream.
The lucky SCP lifted his head, "Glad, I manage to help I guess."
"No need to be modest." said April, "Now then mind telling us, about yourself?"
"Well..." Mark started.
Mark then tell them his life story in the foundation, of course he doesn't remember much about his previous life before the foundation, he tells them the friends he made, the lives he save, and the chaos he prevented all the time. The sisters are getting interested in his life, and keep on listening. For a couple of hours Mark and the Sisters talk and hang out, as they listened to each others stories.
"...And that's how I save Conner from being strangled infinitely by SCP 173." said Mark, remembering the times he save his buddy from many dangerous threats.
"Impressive, few people stood a ground against 173, despite it having lightspeed killing." said May.
"It's great how you healed those people back to normal." said June with a smile.
"Thanks." said Mark.
"Right! Now then shall we proceed to the next experiment?" asked April.
"This does not involve with the previous experiments, is it?" asked Mark nervously.
"Oh, it's not those experiments, its this." said April snapping her fingers.
They were then engulf in a bright light, after the light died down Mark notice he was in a different room, the walls are colored pink, and there's a few stuff lying around, along with a large queen size bed. It took Mark to realize what the experiment is.
"Wait you mean-" Mark was then cut off.
"Yes it's the sex experiment conducted by director Mitch." said April with a smile.
"Are you sure? Because we just met and all that stuff." said the lucky SCP unsurely.
"It's ok we pretty much began to like you, during the course of our experiments we have these strange feelings towards you." said May.
"Not to mention, you help us improve with our experiments, and we decided that we share you." said June cutely.
Mark thinks about it, Sweetie did approve he can have multiple lovers, as long as its true love. He then gave them an answer...
"Ok then, if you gals are cool with it, then lets do it." said Mark with a smile.
This made the three of them happy and smiled. April approach him with a seductive smile, "Be prepared Mark, the experiment will make you feel heavenly. Now take off those clothes."
Mark responded by removing his jumpsuit, along with his white shirt and boxers revealing his slightly muscular body and dick. The Sisters began to admire his body, especially his dick.
April grab his member making him grunt a bit, "My this is such a big penis, compared to the other male personnel."
"It's not that big." said Mark bashfully, looking at the side.
"Biggest penis, we have ever seen." said May grabbing it, with June nodding.
"Sisters, let's us undress." said April towards her siblings making them nod.
The three of them began to remove their uniforms, they unbutton it making them drop down on the floor, showing their chest which is covered by a gray bra, and they pull down their skirts and pant, revealing a gray underwear covering their pussies.
"Does this make you hard, Mark?" asked May seductively.
"Yup." nodded the lucky SCP.
"Good." said April, before lunging at Mark.
She then pinned him down in the bed, then savagely kiss him in which he returned. They swirled their tongues around each other, Mark roams his hands around her back rubbing them, and unclip her bra which showed her E-Cup breasts and groping them, April stops kissing him and smirks.
"Impatient, huh?" asked April.
"Sorry couldn't help it." shrugged Mark.
They resumed their make out, as they wrestled each other's tongues and roam each other's bodies. May then appear behind her sister's behind with a smirk on her face, she then grabs the waistband of her sister's underwear pulling them down, revealing her pussy and asshole making her lick her lips, she press her face near her pussy and began to rapidly lick it and suck her clit, making April moan within Mark's mouth. June then approach Mark's dick and grabs it with her hand, gently rubbing them up and down making the lucky SCP moan within.
May stops sucking her sister's pussy and look at her little sister with a smirk, "Since when did you become dirty and bold my dear little sister?"
"It was during the time, when I watched those adult videos in the internet when I'm alone." said June embarassingly.
"You made me proud, now continue what your doing." said May as she resumed eating her sister out.
June then continue rubbing Mark's dick in which it got hardened, she then place her mouth upon it, and began to suck it like a popsicle. She began to suck faster, as she bob her head up and down rapidly, with May sucking April's pussy hard while fingering it. After a few minutes both Mark and April feel a sensation on their genitals, in which they cum inside the mouths of May & June, as the two of them moaned loudly.
"Tasty, just like ice cream." said June licking her lips.
"Now for the main event." said April.
She was then put in a doggy-style position aiming her ass towards Mark, in which he smirks and approach her raising his dick and thrust forward to her pussy, making the both of them moan, he then moves out and moves in, as he kept on pounding her pussy multiple times while grabbing her breasts underneath.
"Your tight April!" moaned Mark, as he kept on banging her.
"Thank you! Now please go faster!" moaned the elder sister.
He kept on banging her pussy rapidly, while kissing her back and fondles her boobs. June was watching this in which it made her underwear wet, she was surprisingly grab by May and pulls her close.
"Make out with me June." said May, as she kiss her on the lips.
This surprise the younger sibling for a bit, then return the kiss as they wrestled each other's tongues. They roam their hands to each other's bodies, even removing the rest of their clothing revealing their wet pussies, and breasts(May's E-Cups and June's D-Cups), they grope one another, suck on each other's breasts and insert their fingers to each other's pussies multiple times. After a while, Mark who was fucking April's pussy rapidly, felt his balls tightened up and explode within her pussy making him moan, and April's hole also cummed in which their juices mixed together. And at the same time both May and June cum as well, as the two of them squirted a lot of cum. This made them panted heavily, Mark pulled out of her as they lay on the bed.
"That was amazing." panted April with her pussy squirting a lot of cum.
"You said it." said Mark panting as well.
"Is it my turn?" asked May.
Mark saw May laying on her back with her legs spread, and she has a seductive smile on her face. Mark then rapidly fucks May missionary style, making her moan loudly as Mark grope her breasts and suck them making her moan more. June then sucks April's breasts like a toddler, with her arm wrapping around her little sister's head.
"That's right suck your big sisters breast." moaned April, as her little sister kept on sucking.
The lucky SCP kept on pounding May's pussy rapidly, while making out with her. After a few minutes, his balls tightened up then explodes within her making May moaned loudly. Both of them panted for a bit and Mark pulled out of her causing some cum to leak out of her pussy. Next was June who's back was leaning on April's body, Mark grabs hold of his dick and pointed it towards her pussy.
"Are you ready?" asked Mark.
"Yes, now give me your batter." said June.
He then inserts himself within her making her moan loudly. Mark admits that her pussy was very tight, he then began to pound her while fondling her breasts making her moan, April began to lick the right side of her face and giving it a few kisses. Mark fuck her pussy rapidly and April rubs her clit pulling and twisting it making June moan more. After a few minutes June cum on Mark's dick, while the lucky SCP explode within her.
June lets out a couple of pants and fell down, and Mark pulled out of her causing some cum to leak out. Mark notice that he' still hard and April notice this making her smirk.
"Your still hard, huh? Don't worry we got more experiments to do it." said April seductively.
"Oh boy." said Mark to himself.
Few hours have passed...
Mark and the Sisters did a lot of sexual positions even using their powers. First, April place herself on top of May, as the two of them kiss each other with Mark pounding their pussies alternately, then cum within them. Second, June was sucking his dick while April and May suck his balls in which he cums on their faces. Third, Mark put May in a cowgirl position and rapidly thrust upward to her pussy making her moan while bouncing on his dick. Fourth, Mark make April lay on her right side, grabbing her right leg as he pounded pussy and massaging her clit. Fifth, Mark was pounding June on a doggy style position making her moan, while grabbing her breasts fondling them. Sixth, was April and May on a 69 position as they lick each other's pussies while June and Mark make out.
For the next part is where they use their powers, like summoning sex toys. June uses a strap on to pound April rapidly with Mark jacking his dick. Next they summon some vibrators and insert it on the holes of May, making her moan loudly then cum a lot. For the next part they use their powers to give themselves dicks in which it weirded him out, thankfully they're not for him. Both Mark and June double penetrated April as she moaned loudly, feelings two cocks on her holes then the two of them cum a lot on her holes. April then jack off both May and Mark's cock, as they cum on her face and licking it off.
Finally, after countless of hours, Mark was cumming within April, as he let's out a huge load within her womb making her moan. He then pulls out of her, and laid his back on the bed, with the Sisters snuggling up to him.
"That was amazing." panted Mark.
"I agree that was such a thrilling experiment." panted April.
"Who would've thought that you have many stamina." said May recalling the times he pounded her.
"Not to mention, your batter taste good." said June happily snuggling into his chest.
"Glad you enjoy it, also I have another girl SCP who also have sex with me. Are you guys ok with others sharing?" asked Mark.
"Of course, you lucky SCP we'll gladly allow others to share. Besides your our favorite experimental partner." said April, making her other sisters agreed.
"Then it's good enough. Let's get some shut eye." said Mark dozing off, with the Sisters following as they fall asleep due to their sexual experience.
Meanwhile, back on the observation room, all the researchers has gathered the data once again, in which a few of them masturbated.
