A lecture and a wardrobe adjustment

As Lily hurried out of the classroom building, she felt a growing sense of panic. Her mind was racing with thoughts of how she could get out of this predicament, when, to her horror, she found her left hand reaching down underneath the waist of her leggings, and grabbing hold of her panties. Realising exactly what was happening, she made her way quickly to the nearest bathroom as she slowly and unwillingly pansted herself.

Lily speed-walked down the corridor bent over with her bare bottom showing behind her, ignoring the strange stares and wolf-whistles she got on the way. She quickly entered the women's bathroom, made her way into a stall, and stripped off both her leggings and panties, placing her bag down on the closed toilet seat. After two full classes of edging, her panties were soaking wet, and a small amount of her juices had already transferred through to her leggings. She knew that if she wore only her leggings, she would make the stain worse, but she didn't really have much choice in the matter, as the professor had unwittingly told her to go without panties.

Lily left her damp panties on the toilet seat next to her bag, grabbed some toilet paper, and started to wipe up her own juices. With ten minutes to her next class, she didn't have time to grab a change of clothes, but she could at least clean herself up. As she stood there, wiping her crotch, Lily felt her left hand reach up and begin pulling on the collar of her T-shirt. With a sigh, she realised the professor's other instruction meant she was going to have to show off her tits.

With a series of tugs and stretches, her hand widened the collar as far as it would go until the fabric hung loosely around her neck, exposing a daring amount of cleavage. As Lily looked down, she couldn't help but feel a sense of shame, standing bottomless in the toilet stall with her breasts practically bursting out of her top.

Finally, she managed to dry herself off as best she could, and pulled her leggings back on, ignoring the small wet patch she left on the front. As soon as her hands left her leggings, Lily watched herself reach out and unlock the bathroom stall. Quickly, she grabbed her bag before it got left behind, but this knocked her moist panties to the floor. She tried to reach for them, but her body dragged her away. She hoped no one would know they were hers. Lily left the bathroom and made her way to her final class of the day, another lecture.

Lily took her seat in the lecture hall, again sitting inconspicuously towards the back. To her relief, the lecture hall was half empty, but knowing what was coming, she was already longing for the lecture to be over.

Just as the lecture was about to start, Lily felt a gentle nudge on her shoulder. Turning to the aisle, she saw Emily, another of her sisters, smiling warmly at her. Without hesitation, Emily pulled Lily into a passionate kiss, their tongues dueling fiercely as they explored each other's mouths. Emily was usually quite reserved and shy, so this sudden display of affection took Lily by surprise, even knowing it was because of her rule.

As they pulled apart, Emily took a seat right next to Lily. "Hey, Lily. You don't mind if I sit here, do you?" she asked shyly.

Lily could do nothing but shake her head. She didn't want Emily there, not with her current predicament, but she had no good reason to say no.

As Emily looked over at Lily, her eyes dropped to her exposed cleavage, and must have noticed her hard nipples. Without a word, Emily reached out and traced her fingers gently over Lily's exposed chest. Lily could feel the heat rising in her body at Emily's touch.

"What happened to your shirt?" asked Emily, a hint of concern on her voice.

Lily tried to think of an explanation, her mind racing. "Must have put it on the wrong wash setting, I think," she stammered. "I'm still not used to the washing machines here."

Emily furrowed her brow. "That's odd, it wasn't like that in Ms. Chamber's class."

A chill ran down Lily's spine as she realised Emily was in her class this morning, when she had apologised to everyone. Hopefully she wouldn't get any more commands from Emily. Emily's fingers began to trace slow circles around Lily's nipples through her t-shirt, rubbing the rough texture of the material on her nipples.

Emily looked at her for a moment, her eyes narrowing slightly. Lily could feel Emily's gaze, as she kept caressing Lily's breasts.

"Maybe it was the dryer," said Emily finally, her voice holding a hint of amusement. She leaned in closer to Lily, her breath warm against her ear. "Or maybe you just can't resist showing off your sexy body."

Lily felt her face flush, and was again surprised by Emily's forwardness. Then, to her horror, she found herself pulling at her collar, and lifting her left breast with the other hand, exposing herself. Apparently 'sexy body' had triggered the compliment rule. As Lily sat there, holding her breast, she tried to think of a way to play it off. "Why are you so interested in my chest? Maybe you're just a secret pervert, Emily," she said playfully.

Emily looked away, her cheeks turning pink, but her hands never left Lily's body, caressing her while she put herself on display. Soon, to her relief, Lily could release her own breast, but it wasn't long before the lecture finally began. As Lily had now come to expect, her left hand began to wander under the waistband of her leggings. She knew she should try to stop, or hide it, to move away from Emily, but there was nowhere to go. The first sensations of her fingers brushing against her bare, wet pussy sent shockwaves through her body, and Lily braced herself for the oncoming waves of pleasure. Lily's hand caressed her gently at first, spreading her juices all across her opening, and Lily started to breathe harder as the pleasure built.

Emily, oblivious to Lily's activities, continued to absent-mindedly caress Lily's breasts. She occasionally tweaked Lily's nipples, causing sharp jolts of pleasure to shoot through Lily's body, driving Lily wild.

As Lily's left hand moved, circling her clit faster and faster, her muscles began to tense, preparing for the release that never came. She could feel the familiar pressure building inside her, but just as she thought she couldn't hold out any longer, Lily felt her left hand stop, leaving her hanging on the brink.

Her breath caught in her throat as she sat, **** for release, **** to cum. She glanced over at Emily, who had finally noticed the state she was in and looked slightly concerned. Lily **** herself to calm down, taking deep breaths and trying to control her body's urges.

Then, to her horror, her left hand resumed its duties, slipping between her legs to rub her swollen, sensitive nub as Emily watched from beside her. Lily could feel the sweat forming on her forehead as she fought against her body's urges. She knew she had no way to explain this to Emily, but as her left hand continued to move against her will, she could feel the pressure building inside her once again.

Emily's eyes widened in surprise, glancing down to Lily's crotch, and then back up to her eyes. "Lily, we're in class!" she protested, her voice a sharp whisper of rebuke. "What are you doing?"

Lily gritted her teeth, her entire body tense with the effort of not giving in to the pleasure coursing through her. She let out a soft moan, as Emily's fingers dug deeper into Lily's breasts, matching the pace of Lily's own hand.

"I can feel how turned on you are," Emily whispered, her voice barely audible above the sound of their breathing. "You're so wet, Lily".

Lily looked down to see a dark stain across the front of her leggings, and blushed. To her shock, Emily then put down her pen and began to massage Lily's breasts with both hands.

While Lily gently stroked her own pussy, Emily teased both Lily's nipples, driving Lily closer and closer to the brink. Her muscles tightened, ready to explode, but once again she was denied, her pussy clenching while her hips thrust underneath the desk.

Lily's head fell back against the chair, her body trembling with the effort of holding back the orgasm that threatened to consume her. Emily watched her, pawing at her breasts, her eyes filled with lust.

"You want me to slow down?" Emily whispered in Lily's ear, her hands still caressing Lily's breasts. Lily's breath caught in her throat, but she nodded, and Emily's hands slowed.

"Sorry if I made you uncomfortable," Emily continued, "but I can't deny that I found it, well, kind of hot."

"Yeah?" Lily responded in a flippant whisper, still catching her breath. "Next class, you should try it."

Emily watched as she paused for a moment, before Lily's hand began sneaking back under her waistband to tease her aching pussy. "You talk big, but you're going back for more already. You'll have to remember to wear your vibrator to class from now on."

Lily left out a soft moan at the suggestion, as her fingers again caressed her wet folds. She knew Emily didn't mean it, but she really didn't want any more commands right now. Hopefully she could fix this after her classes ended.

"Maybe let's just focus on the lecture," she suggested, turning her attention back to the front of the hall despite her hand's continued stimulation.

Emily seemed a little offended. "Okay, weirdo. You're the one getting off in a lecture about Ancient Greece." Emily then returned to her notes, only lightly caressing Lily with one hand.

Lily found herself pushed to the edge three more times until, after what seemed like an eternity, the lecture finally ended, and she could stop, even though her body was aching for her to finish. As the professor left the stage, Lily could feel the damp stains under her pits, and her wet leggings clinging to her pulsing crotch. Finally free to fetch her phone, she quickly grabbed her things and hurried out of the room, her cheeks burning with embarrassment. She knew she had to find a way out of this mess, and fast.
