A steamy shower and a confrontation

At 11:00am, Lily's alarm broke her out her deep sleep. She reached over and turned it off with a groan, reluctantly dragging herself out of bed. As she did, a hand dragged across her shoulder, and she looked back to see Chloe nude on the bed behind her, still asleep. Lily took a moment to watch as Chloe's breasts rose and fell with each breath, the lingering scent of sex still hanging in the air after last night.

Lily was conflicted. On one hand, she'd finally managed to approach Chloe, and they'd had a night of crazy sex, just like in Lily's wildest fantasies. On the other hand, it had only happened because Lily had discovered a magic app. Lily felt guilty for taking control of Chloe like that, but she hoped she could make amends with her this morning. First, she needed to go wash off the smell of sweat and sex, so she grabbed her shower caddy and headed for the communal shower.

Lily stood in her shower stall, soaping herself under the hot water for several minutes. As her hands moved over her body, her thoughts drifted back to Chloe's naked body and the desperate look on her face before she came. Lily began fantasising about making more rules. The idea of having her whole sorority following her commands made her warm between the legs.

Lily continued soaping herself, focusing more intensely on her breasts and nipples. She pinched them gently, breathing sharply at the pain. Her fingers drifted down to her pussy, and she started stroking herself, thinking of everything she could do with the app. She'd had it for one day, and she already had Chloe entirely under her control. She'd barely even touched the settings tabs. She closed her eyes, focusing on the heat building inside her.

Thinking of Chloe, Lily's fingers started moving faster. Her knees wobbled as her orgasm got closer, and she leaned against the shower wall for support. She started working on her clit, and just when it felt like she couldn't take any more, her body shuddered, and she moaned loudly in pleasure as she came, hard. The hot water pounded against her as she furiously rubbed herself, convulsing.

As the afterglow faded, Lily opened her eyes and went to turn off the shower. Only then did she realise that she'd forgotten to close the stall door. Panicking, Lily also noticed Brooke, from the room down the hall, staring at her in shock through the open door. She quickly grabbed her towel, covering herself.

"Um, hey Brooke," she managed to say. "Just having a shower. Did you, um, see anything you shouldn't have?"

Brooke shook her head, flustered. "No, it's fine. I mean, I didn't see anything." Her eyes nervously fell to the floor. "I was just... surprised. N-Normally I have the bathroom to myself around now."

"Guess I slept in late after the sorority party," shrugged Lily awkwardly.

"Yeah, I, um, heard some noises last night. You were up pretty late."

Lily's face flushed crimson. "Oh, um, yeah. We got a bit loud, didn't we?" she said, trying to make it sound casual. "Sorry about that. The walls in this place are kind of thin."

Brooke started to back away from the door "I-I didn't mean to eavesdrop or anything. I just, uh-"

"Well, I'm all finished in the shower now. All yours." Lily interrupted, desperate to get back to her dorm room.

"Um, no offence, but I might use another stall."

As Brooke left for her shower, Lily quickly dried off and wrapped herself in a towel. In her post-orgasmic clarity, she decided that she needed to make things right with Chloe.

Lily returned to the room to find Chloe naked, frantically pacing around the room. Chloe gripped her panties tightly in her hand, and turned angrily to Lily as she entered the room.

Before Lily could say anything, the greeting rule forced her to step forward and greet Chloe with a kiss. However, this was not the tender, friendly kiss from last night. Chloe's lips were tight, her mouth closed as Lily pressed her lips against her. After a long, tense moment, Lily pulled away.

"What have you done to me, Lily?" Chloe demanded, thrusting the panties in the air at Lily. "You made me do all those things last night, and now I can't wear any clothes?"

"You can't put on clothes?" Lily asked. Why was Chloe stuck naked? What had she told- oh! "What did I say last night? Something like stay naked until tomorrow?"

Chloe rolled her eyes. "Oh, of course." Chloe threw the panties at Lily, to no effect. "What's with these stupid rules? Why do I have to do what you say?"

Lily felt bombarded by the questions. "Chloe, Chloe, calm down."

"Fine," she said through gritted teeth. "But I want answers. What the fuck is going on here?"

Lily took a deep breath. "I, uh, found a way to make people follow my rules. Magically." Lily said quietly. "I'm sorry, Chloe, I was upset last night, and I guess I got carried away."

"Carried away? Are you kidding?! I can't even get dressed!" Chloe held Lily in a mean glare. "I can't go back to the house like this. I could get arrested for indecent exposure!"

Lily thought for a second. "I said naked until tomorrow, right? What time did we get in last night?"

Chloe's eyes widened in realisation, "After midnight. Great. So I'm stuck like this for the day."

"It could be worse," said Lily, optimistically, but on seeing Chloe's reaction, knew it was the wrong thing to say.

"Oh really? It could be worse?!" Chloe's anger flared, "You turned me into your little sex puppet last night, and now I'm stuck following your dumb commands! Go fuck yourself, Lily."

Chloe's anger hurt, but Lily knew she deserved it. She turned away from Chloe, ashamed, before confusingly dropping her towel and laying herself down naked on the bed. Possessed, Lily rolled onto her back, facing Chloe and spreading her legs wide, presenting Chloe her pussy.

Lily felt her left hand reach out to the used vibrator on the night stand, and a wave of confusion washed over her. What? Why am I doing this? Lily tried to stop herself, but her fingers closed around the vibrator, and she turned it on, the motor rumbling vibrations through her hand. Lily lay there, legs spread, and slowly pressed the toy against her clit, still raw and sensitive from her session in the shower. The intense buzz rushed through her sensitive nerves, and she let out a reluctant moan.

Chloe watched in disbelief as Lily started to fuck herself with the toy. "What the fuck, Lily?" she yelled. "I'm standing right here!"

"I know," Lily whimpered, fighting back arousal, "but I can't stop".

Lily watched her own hand lift the vibrator from her clit, and bring it instead toward her warm, wet pussy, poking just the tip inside herself. She closed her eyes as she held it there a moment, feeling the vibrations pulse between her folds, before she plunged the toy deep into her pussy. Fully inserted, the second arm of the vibrator pressed hard against Lily's clit, and the tip of the main arm tickled her G-spot. Lily let out a series of moans as the vibrations of the toy pulsed through her.

Panting, Lily opened her eyes again. Chloe had turned away from her, hands on her ears, trying to ignore the spectacle. Lily's gaze drifted across Chloe's naked body, focusing on her tight, round ass before drifting to the hint of pussy between her legs. Lily pictured herself tasting Chloe, watching her aroused reaction as Lily brought her to orgasm again and again.

But just as Lily began to lose herself in the fantasy, Chloe turned back, staring Lily down with a menacing glare. Trying to distract herself from what was happening, and figure out why she was doing this, Lily quickly thought through the events of last night, and then this morning. Why would she- Oh no!

She had apologised to Chloe this morning. Her eyes locked on Chloe's as she tried to explain.

"You made me do this, Chloe," she panted. "You told me to go fuck myself, and I have to obey your commands."

"Yeah right!" Chloe yelled back, eyes drifting to the wet spot on the bed between Lily's legs, "You're getting off on this. If you really have to obey my commands, get out of here and go do that in the hallway."

Lily made a few more thrusts with the vibrator, the hum of the motor droning in and out as it was muffled by the folds of her pussy. Then she pressed the toy deeper inside herself, and held it there. She felt herself stand up, holding the vibrator in place with her right hand, as she shuffled towards the door. There was nothing she could do. She had to obey.

Chloe watched her, open-mouthed. "What are you doing?"

"What you told me," Lily replied, her voice shaking as she pushed the door open and stepped out naked into the hallway.
