Her ass and panties

As your eyes roam over Ashley's body, you notice that she looks hot. Not just attractive hot, but overheated hot, probably from her jog. It actually makes you feel a little bad that she's drinking just tap water.

"You know, if you want you can get some ice from the freezer for your drink," you tell her.

"Really?" Ashley says, her brown eyes lighting up with joy, "Thanks John! I owe you one!"

"No problem," you say. As she turns around towards the freezer to get her- your ice, you take the opportunity to check out her ass. You always had a particular fondness for it. While her ass wasn't the biggest, all that running she did made it toned and firm, something you considered to be a major plus. And with a few words, it could be yours.

...Unless this really was just an elaborate birthday prank on Ashley's part. Then you'd just make yourself known as a perverted creep to your friend. Is it worth the risk?

...Fuck yes it is, that ass is a treasure.

You walk up behind Ashley as she finishes getting ice and with a slight nervousness you declare, "I own your ass now, though."

Ashley pauses for a brief moment and looks over her shoulder at you. Before you have time to stammer out an apology though, she nods and says, "Yeah, okay. Anything in particular you want me to do with it?"

To say you were flabbergasted was an understatement. It took you several seconds to recollect yourself, during which Ashley took a sip of her ice water like what she just said was completely normal. Eventually, you blurt out, "L-Let me play with it a bit?"

"Whatever you want," she says casually, leaning forward a bit to stick her ass out at you. Tentatively, you reach out and place a hand on her butt cheek. When she doesn't move, you proceed to squeeze and knead the firm flesh, not quite believing what is happening right now.

"You're really fine with this?" you ask, setting down your drink so you can use both hands on her ass.

"Why wouldn't I be?" she responds, "You can do whatever you want with your ass, even if it is technically a part of my body."

"Even this?" you say, and deliver a sharp slap to her ass.

She yelps and jumps a little from the shock, splashing a little water on her tank top. She coughs a bit, then says, "Yup, even that."

Okay, that 95% convinced feeling you had just went up to 110%. There was absolutely no way Ashley would so easily tolerate this from anyone, even as a joke. As unbelievable as it was, you now owned her ass.

Seeing her white panties poking out from her waistband, you get an idea. Grabbing the hem of them, you tell her, "Hey, since you're wearing these panties over my ass, it stands to reason that I own these too."

"Yeah, that makes sense," Ashley says, before going wide-eyed and asking, "Crap, is it okay that I'm wearing your panties? I'm so sorry if it isn't, I..."

You interrupt her by yanking the panties up as hard as you could, giving her a wicked wedgie. She lets out a shriek as your pulling brings her onto the tips of her toes, and she spills even more of her drink in the process.

"I dunno," you say playfully, still holding the panties up, "Is it okay for me to do this while you're wearing them?"

"O-Of course," she says in a strained voice, "It's my fault for wearing your panties without your permission."

"And if I told you to take them off right this second, without leaving the kitchen, would you?"

"I would," she says without hesitation, "They're your panties after all."

You hold the waistband for a few more seconds, then let go of the panties. Ashley hisses in pain and clenches her legs a bit.

"Damn, guess I deserved that," she mutters, "So, do you want your panties back or not?"

You think about it for a moment, then tell her, "You can keep wearing them for now. Next time you take them off though, I'd appreciate it if you kept them off and returned them to me ASAP."

"Got it," she says with a nod, "Thanks a lot, John."

"Of course," you say, before a thought strikes you, "Oh, one more thing."

"Hmm?" she says, taking another drink from what's left of her water.

"I want to be able to see my ass," you tell her, "So if it's not too much trouble, I want you to keep it bare when you are in the apartment."

"That's fair," Ashley says with a hint of hesitation. She sets down her drink, then shimmies the back of her jogging pants down so that the firm pale globe of her ass was sticking out. Thanks to the panties being firmly wedged up her ass-crack, her butt was now on full display for you.

"Damn, this is uncomfortable," she mutters, her face slightly red from embarrassment, "I feel like my pants will fall down any second. I'm gonna have to either start wearing skirts or have a pair of pants with the back cut out for home."

"Those sound like fantastic ideas," you tell her. You finally take a bite of your long-neglected toast, not even caring that it's no longer hot, and start thinking about what you want to use your newfound power for next.
