You proceed cautiously

A part of you wants to move immediately to testing out your strange new ability on Kelly, but another, more cautious part of you understands that she won't simply let you write something on her skin. You decide that you'll need to find a way to convince her to allow you to experiment while minimizing the repercussions to yourself if it turns out that the ability only works on objects. You wonder what would happen if you wrote your name on something valuable, like money. Or a cellphone. You wonder if such items can be used as effective bargaining chips to get you what you want.

“Hey, Mrs. O’Brien, can I borrow your phone for a minute?” you address Andrew’s mother. “I need to make a quick call.”

“I don’t see why not, especially since you’ve been so understanding with us,” Kelly replies pleasantly. She bends down to grab her purse, giving you a deep view of her generous cleavage. Her hands sift through her purse and come back with one of the newer Apple smartphones.

She holds the device out for you to take. “You forget your phone at your house?”

“Y-yeah, totally,” you take the offered phone. “Thanks.”

"You're welcome," she smiles at you.

You walk to the living room and hold the smartphone in front of you. You know that cellphones are a valuable tool to a lot of people. It might make for a useful bargaining chip.

“Well, here goes nothing,” you use the sharpie to write your name on the phone. Nothing strange or mystical happens that you can see. You only see the black lettering of your name marring the light blue frame of the phone.

You walk back to the kitchen after a few minutes to find Kelly and Andrew finishing the last bits of their hot sandwiches.

“Thanks for letting me borrow your phone, Mrs. O’Brien,” you say. You hold out the smartphone in front of you for Kelly to take.

“Oh, no prob-” she stops mid-sentence and stares at her phone for a moment, as if something is catching her eye.

“This isn’t my phone, Ryan. It’s yours,” she gives you an uncertain look. “Here,” she holds the phone out for you to take.

“Uh, thanks?” you take the phone from her.

“Mom, what were you doing with Ryan's phone all this time?” Andrew frowns at his mother.

“I have no idea, honey,” Kelly has a distressed look on her face. "I'm so sorry, Ryan. I didn't steal your phone, I just... had it."

"That's okay, Mrs. O'Brien. Like I said, Andrew's my best friend. I don't mind you guys using my stuff, so don't worry about it," you wave dismissively. Kelly and Andrew both smile at you.

The phone in your hand vibrates. A text message pops up. It's from Samuel O’Brien; Kelly’s husband and Andrew’s father.

Company trip went well. Will C U tomorrow.

So Mr. O’Brien won’t be back home from his business trip until tomorrow. Normally, this wouldn’t register among your concerns, but you feel like you’ve just stumbled upon something special. Something potentially world-changing. An older, more enterprising man in your position would probably be planning to write his name on something priceless like the Mona Lisa and sell it to the highest bidder, but you’re an eighteen year-old boy infatuated with his friend's mother. You have much simpler concerns.

Your heart thuds heavily in your chest as you wonder what would happen if you wrote your name on a person. Could you really own Kelly O’Brien? A part of her? Her big tits. Her plump ass. Her mouth. What if you could own aspects of her personality? Her mind. Her devotion. Her love. Would Andrew and Mr. O’Brien just accept it like Andrew accepts that you own his kitchen table and his mother’s cellphone?

Images of Kelly O'Brien submitting to your ownership flutter across your mind. You imagine Kelly's big breasts bouncing up and down as you pump in and out of her tight pussy. You can almost hear her scream your name as she comes for you, her all-powerful owner.

Your manhood thickens. You should be admonishing yourself for thinking these things about your friend’s mother, but the intoxicating potential of your strange new ability is almost too much to resist. What if you really can own people? What if you can own Kelly O'Brien? The idea is so delicious and enticing that your formerly strong moral convictions are crumbling under the weight of it.

“Ah, I’m stuffed,” your best friend’s voice breaks you from your train of thought. "Wanna go back upstairs, Ryan?”

You look over at the redhead. He’s already taken his plate to the sink and rinsed it. Your stomach gurgles and you realize that in all the confusion, you still haven’t eaten.

“Not yet, man,” you tell him. “I still gotta eat.”

“Well you'd better hurry up, bro, or I might just sell that sword!” Andrew claps you on the shoulder and disappears up the stairs.

You just shake your head and sit down at the table, which now belongs to you. Kelly is sitting across from you, despite having finished her sandwich. She's giving you a look that reminds you of the one your mother has when she thinks you aren’t taking care of yourself properly.

“I can’t believe you didn’t eat. Aren’t you hungry?” Kelly says, her voice laden with concern. It finally occurs to you that you’re alone with Andrew’s mother and your earlier thoughts of owning her rush to the forefront of your mind.

You take a bite of your sandwich to distract yourself. The gooey Parmesan, the sauce and the chicken contrast perfectly in your mouth as you chew. You let out a moan.

Kelly laughs. “I guess that answers my question.”

You gulp down the mouthful. “Thanks for not letting me eat alone, Mrs. O’Brien.”

She gives you a warm look. “You’ve been incredibly generous and understanding with Andrew and I tonight. Besides, someone should stay here and keep our guest company," she glances meaningfully at the stairwell and you laugh.

“Speaking of generous, why don’t you use my phone until you get your hands on a new one?” you say. You push Kelly's, or rather your phone across the table.

Kelly’s eyes widen and she waves her arms in front of her. “Even though I could really use a phone, I couldn’t possibly take yours, Ryan. Not after I've been keeping it from you all this time!"

“It’s okay, I still have the one I left at home, remember?” you try to reassure her. She doesn’t look convinced, so you enact the next step of your plan. “What if I had you do me a favor in return? Would that make it alright?”

“I guess it would depend on the favor, but I still don't feel comfortable with this,” she folds her arms across her chest, which has the delightful side-effect of pushing her breasts upward. You bite your lower lip.

Remembering Kelly’s instinctive respect for your property rights, you go in for the kill.

“I get to decide how something I own is used, right?”

She nods as if that were the most obvious thing in the world.

“So if I want to let you borrow my property in exchange for a favor from you, you shouldn’t feel bad about it.”

“I… you’re right,” Kelly says, her green eyes accepting. “Okay, I’ll use your phone until I buy a new one. I will be doing you a favor, though, just so you know. No if, ands, or buts about it. So, what’ll you have me do now that I’m indebted to you?”

Your cock twitches.

“H-how about you let me write a small message on your arm?” you say.

She frowns at you.

“No?” you say.

“Uh, I don’t know,” she mutters uncertainly. “That's not something I was expecting…”

“I know it’s a little weird, but you said you could use a phone right? This one just so happens to have all your contacts programmed into it. A small message on your arm and it's yours for the time being. Come on, this is how I want my phone to be used."

Kelly sighs and holds out her right arm, placing the back of it against the cool, dark wood of the kitchen table. You marvel at her smooth, creamy skin for a moment before she speaks.

“Alright, you can write on my arm,” she says, her tone growing more firm. “Just... don't put down anything too embarrassing. It's too hot to wear long sleeves, you know?"

“S-sure,” you say, caught entirely off guard by Kelly’s acceptance of your request. You can hardly believe this is really happening.

“Well?" she raises her eyebrows at you. "What are you waiting for?

You nod and pick up the sharpie. You put your left hand on her arm to steady it. You savor the softness of Kelly’s skin for a moment before you put the sharpie up against her skin. Your fingers tremble with anticipation.

Kelly shudders. “Oh, that tickles."

You grin, happy that the tension between Kelly and yourself has dissipated.

You steady yourself and begin to write.
