Isaac Night wasn't one for socialising. He preferred to stick to the small group of people he knew he could trust with secrets he would never tell. Though, one girl had managed to worm her way into to the cogs of his heart with her quiet intelligence and kindness towards his sister Francoise.
Y/n didn't bother with people- not unlike her boyfriend Isaac- she was a quiet girl who preferred to show her gratitude with small smiles and walking drawings that pictured flowers and animals.
She was a smart girl who used her power of picture motion wisely, often she would draw intricate designs of varying machines that would float its way to the boy sat next to her when in class.
She would later be called into Iago tower by Isaac, a tall structure stood proudly in the middle of his secret laboratory. It was familiar, the welded swirling pattern around the edges- the same ones from her blueprint.
"Oh, Isaac." Y/n sighed wistfully as she circled the invention, her eyes gleaming as they usually did when he would bring her drawing to life in a way she was uncapable of. "It's beautiful."
Isaac watched from his place stood by the nearby railing, his gloved hands clasped in front of his white coat as he analysed the girls facial expressions.
"It was by your design- the reason for its beauty." His response was smooth, each word coated in false indifference.
Y/n came to stand beside him, admiring the creation from the boys side. "You're a smooth talker when you want to be, Isaac." She teased, a thought jumping forth in her mind. How would she repay him?
"I'm sure you want something in return." The girl stated as she turned to look at him.
The boy in question thought for a moment before his dark eyes steeled her with a unyielding force. "I do have an experiment I've been waiting for a test subject for."
"Me." y/n cut in "I'll be your test subject!" Her hand came up to grab his arm, a loving squeeze followed the gesture.
A sinister smile grew on his face. "Excellent." His word were drawn out as he ushered her to the other side of the second floor, a normal looking chair stood lonesome in the cluttered room.
"Sit." Came the clipped instruction Y/n was quick to follow. With a careless flick of Isaacs hand, restraints that once hung loosely from the chairs armrests flew to cover the girls wrists.
She looked between them unsurely for a moment. "Are these necessary?" She queried as the same happened to her ancles.
"Can't have you moving around during the experiment, now, can we?" The boys voice carried across from the workbench situated in the centre of the room.
His head lifted from the paper chart on the table, his eyes meeting hers comfortingly. "Do you trust me?"
Y/n's nod answered quickly.
"I need words, Y/n." He wouldn't do anything she was not comfortable with.
"Yes, I'd trust you with my life."
His head nodded, pleased with his girlfriends response. He lifted his hand lazily in her direction, his fingers puppeteering invisible strings that attached himself to her.
Y/n jumped slightly at the feeling of a caress against her cheek, though the source of it was not visible. It felt as if Isaac's own calloused fingers he hid beneath those gloves he always wore were rubbing against her supple skin.
"I am going to ask you a few questions as this test goes on." Isaac proclaimed as a second invisible hand wrapped around her shoulder.
"Firstly, can you feel that?" He questioned, though he knew her answer by the way she had jumped upon contact.
Y/n sucked in a breath of air as she felt the hand on her shoulder lower towards her waist. "Yes, I can." She answered.
Isaac nodded, his eyes were gleaming with mischief as his knuckles bent. "Good. Now tell me what it feels like. What is it doing?"
"It feels like your hands." The girl started to explain. "Their cold against my skin, one is squeezing my waist the other is resting on my cheek. It's feels like you over here with me."
She felt herself grow damp between her legs at the situation, her eyes never leaving his.
Night hummed in satisfaction, his left hand tilting downwards, controlling the phantom one on her waist to trail onto her plush thigh. The hand on her cheek followed the other one, stopping just before the mound of her breast.
Y/n's breath hitched as she watched her legs be parted by the invisible appendage. They stopped suddenly and her head snapped up to look at the boy at the table, a questioning look graced his handsome features.
"Carry on, My Love." She urged. "It's for the experiment, right?" Her lips tilted into a knowing smirk that the boy soon mirrored.
The hands resumed their previous exploration, diving deeper between her thighs.
"Now." Isaac started. "The next experiment tests if my powers can reach your skin through your clothing."
As he said that, Y/n felt the hand on her chest roll her nipple between its fingertips.
"Mm~ Yes." Her answer was broken by a shocked moan. The second hand rubbing small circle on her begging clit.
"Tell me, sweet girl, tell me what your feeling." Isaac looked dishevelled, his hair had fallen into his face from the heat rising in the room.
If he were a man with lesser restraint he would have already ditched the experiment to touch her with his own hands. He was pained when he realised he wouldn't be able to feel her through his power.
The hands a copy of his own, touching her body, feeling her slick on their fingers. The Inventor was jealous of his own hands.
"I feel like you should test if I can feel them inside of me." Y/n needed more, the teasing touches only getting her so far.
Isaacs eyes scrunched shut at her words, his fingers dancing in the air as he guided the copy to circle her entrance before her walls clenched as it entered.
He wanted to slap himself for putting him in this predicament, though, he could do that later, strangely enjoying watching his girlfriend writhe on his phantom fingers.
Y/n's moans echoed around the cluttered room, the feeling so intense she never wanted it to end.
"F-fuck, yeh, Just like that, Isaac."
A quiet groan left the mentioned boys lips, his mouth opening slightly as his brows scrunched. He watched as her eyes led her head into falling back onto the chair, his trousers felt too tight at the sight.
She felt her mind fog up as the copy of her boyfriends hand came up to rest on the junction of her throat, grabbing carefully to lift her head up from its limp state to look back at him.
"Eyes on me, sweetheart." His course voice begged.
Soon Y/n felt herself teeter on the edge of her climax, the phantom hand between her legs adding a second finger to the mix.
"Isaac-" She broke off into a drawn out moan, unable to finish her warning as she came on the invisible hand.
The boy hunched over the work bench, his hands shooting down from the air to grasp the tables edge, his knuckles turning white from the force.
As the girl came around after such a magical high, her eyes clung to the figure of her boyfriend breathing heavily, looking towards the ground.
"Isaac?" His name soft against her tongue. "Are you alright?"
The boy answered by flicking his hand in her direction once more, the restraints around her wrists and ancles falling limp against the armrests of the chair once again.
Her legs were shaky as she made her way towards him. When she reached him she placed a comforting hand on his shoulder, following his eyeline to the wet patch on the front of his trousers.
Y/n stifled a good natured chuckle. "Aw, did you cum in your pants, angel?" Her tone was mocking in the most loving way.
Isaac huffed a breath as he turned to her. "You can leave now, the experiment is over."
Her smile was as strong as ever as she replied. "I think the results were clear. You can use your powers to make two please come at once!"
The boy rolled his eyes, his cheeks tinged pink with embarrassment.
Though he knew he would defiantly be doing it again.
