Kelly, a prankster with a mean streak

Naomi and her family greeted the Resident Advisor on their way in, who gave them a quick tour of the building. The common area, gym, pool, and laundry room were located on the ground level. Naomi was on the top floor, which meant no noisy upstairs neighbors to worry about. However, it was a five floor tall building, which meant she wanted to take the elevators instead of the stairs. Her parents agreed, and the RA showed them around her floor. Each room housed two students in bunk beds and there was a communal shower at one end of the hall, while the restrooms were on the other.

The RA handed Naomi her room key and opened the door, introducing her roommate. Kelly is a tall athletic girl with long brown hair, and a thin frame that did well to accentuate her curves. She had D cup breasts and slightly rounded hips. Naomi was a bit shocked to see a girl so much taller than her. She barely reached her chin, which meant her eyes were level with Kelly's large breasts.

The tall girl smiled at the naked Naomi. She looked forward to pranking her new roommate, catching her in her underwear or exposing her to neighbors. However, she didnt dream of someone so cute and naked to fall into her lap! The two shook hands and Naomi explained the circumstances that led to her nudity. As Naomi's blush grew, so did Kelly's smile. Naomi's parents left, placing the suitcase next to Naomi.

"Let me get that for you. You'll have the top bunk." Kelly explained.

Naomi watched as Kelly effortlessly lifted the suitcase up, making her duck out of the way as it flopped onto the bed. Naomi couldn't even see the bed from her angle.

"Since I'm so tall, it sounds easier for me to climb up, but with how big I am, I'm just not sure the frame can hold me. I'll feel safer if you were up top." Kelly explained.

"How do I even get up there? Theres no ladder." Naomi said, pointing out the obvious.

Kelly smirked as she planned her first prank so well. Getting there early, she found out the ladder could be removed to save space. It was nestled under the bed, which was part of the reason why she chose the bottom bunk. The other was for what was about to happen. Kelly lay herself down on the bed and shrugged. Naomi sighed and lifted her foot to stand on the bottom bunk's frame before hoisting her other leg up to straddle the edge of her bunk, giving Kelly a spectacular view between her legs, and the vibrator sticking out of her butt.

"What's that?" Kelly asked, knowing exactly what it was.

"What?" Naomi asked, trying to play dumb.

"That thing in your ass!" Kelly shouted.

"Its a...heartrate monitor. I have to keep it in to keep track of my steps and monitor my fitness progress." Naomi lied.

"You had that in you the whole time?" Kelly asked.

"Um...yeah." Naomi lied again.

"So, instead of wearing a normal wristband, you went with a buttplug?" Kelly asked.

"Can I get dressed in peace?" Naomi asked, rummaging in her suitcase for an outfit.

Kelly got up and turned the dial on the base, making the vibrator turn on. Naomi involuntarily shuddered as the erotic teasing resumed, and her crotch became wet again from the stimulation. Her sexual frustration quickly returned as the hunger for an orgasm became nearly irresistible.

"That doesnt sound like a heartrate monitor! Haha!" Kelly joked as she pulled the suitcase off the bed.

Naomi barely moved as she fought the urge to touch herself, not wanting a total stranger seeing her orgasm. However, she didnt have the nerve to turn it off either. She could only lie down on her belly and watch what Kelly was doing.

"Well, it seems you weren't telling me the whole story, slut. I think you get off on being naked in public. So, I'll go ahead and make things easier for you. Its warm here so all these long sleeves and any bottoms with legs can go. Oh, and say goodbye to your bras and panties. Huh, I guess that doesnt leave much, does it? Maybe you'd like it if you just went naked?!" Kelly joked, trying to judge Naomi's reaction. The naked girl could only groan in sexual and mental frustration.

"Hmm you dont seem to be of sound mind. Perhaps I should make this decision on your behalf. I'll just go throw these items away and take your suitcase to the RA as we discuss your new living situation." Kelly said as she left.

Naomi couldnt believe how easily manipulated she was. She had the chance to stop her, but she rather lay down and let her libido control her. Now that Kelly left, she didnt even think about going after her. Instead, she was contemplating fingering herself and finally achieving orgasm. She had a tough decision ahead of her.
