It was late in the evening and Chastity could barely hold a coherent thought. She'd been trying all day to resist, to focus on her assignment, all to no avail. She'd barely written a paragraph.
She closed her eyes and locked her fingers over her mouth, willing her hormones to simmer down. Begging, praying they wouldn't hold her hostage.
She knew it was futile.
"Dear patrons, the college library will be closing in twenty minutes. We wish you safe travels home this evening and thank you for your patronage."
Chastity closed her laptop and began packing up her things, unaware that a man was staring at her from across the room, hidden in the shadows of the book stacks.
He had caught her scent six hours ago when she'd walked in, her hurried steps creating a gentle breeze upon which her aroma had travelled, straight to his dick. She was in heat, and he'd been rock hard, willing himself to resist her. There were only five people left in the study room, and he was losing his strength as each student left.
Aaron was a breeder, and it had been three days since his last rut with a bitch. He'd been strong, resisting the perkiest blonde yesterday, but something about this bitch's scent sang to him, drew him in from the depths of his ballsack.
Chastity stood abruptly. Her skirt had creased out of shape from the hours of study, so Aaron caught a nice long look at her panties. Lilac with white flowers.
He groaned and gripped the edge of his table in sheer agony. His cock fought hard against his pants.
There was only one way tonight would end.
She straightened down her skirt and collected her bag, but instead of heading to the stairwell as Aaron had expected, she walked deeper into the library.
Such easy prey, the girl had no idea what she was in for.
Chastity found her way to the bathroom, desperate for a few moments of strength. Or, at least, some privacy while she sorted herself out.
In the mirror, she could see that her cheeks were flushed a deep crimson.
"Jesus, Chastity, look at the sight of you," she scolded herself as she splashed some cold water on her face.
As she went to shut off the tap, she knocked the lever the wrong way by mistake. A huge torrent of high-pressure water spurted up from the sink, covering her shirt. She quickly fought through the stream and shut off the tap, beyond frustrated by her own stupidity.
Her white shirt was now sheer, her desperate nipples attempting to break through her bra for release.
She couldn't walk out of the bathroom in this state - she had no jumper to cover up, and she was certain there had still been people studying. Thankfully, the bathroom was empty.
Chastity unbuttoned her shirt and held it under the hand dryer. This fabric would dry quickly, but her aching nipples and throbbing pussy distracted her from this confidence.
She brushed her hand over her bra, her firm nipple relishing in the brief attention. She needed release. With a quick glance over her shoulder, Chastity traced her hand down her abdomen, under the band of her skirt to her panties. They were completely drenched in her juices.
She slid two fingers in, warm from the dryer, and gave the lightest flick to her clit.
Chastity moaned louder than she expected. She gasped and withdrew her hand quickly, clamping it firmly over her traitorous lips. But it didn't help - she could smell the aroma of her pussy on her fingers, weakening her resolve further.
"Right," she whispered to herself, trying to regain some sense of control. "Five minutes, that's it."
Chastity peeled off her soaked panties and draped them over the tap to air dry a bit. Her shirt was mostly dry, so she put it back on but didn't have another spare second to button it. Her mind was crazed, focused so certainly on the one thing that would give her relief.
With her last functional brain cell, Chastity made sure to close the bathroom stall behind her before she got to work. She sat atop the toilet seat, leaning back as far as she could and spreading her legs to the stall walls. Her fingers made no delay - there was no need for saliva to moisten things up at all.
Chastity stroked her pussy gently, drawing a relieved moan from deep within her chest. It was burning hot and dripping with her juices. She pressed a manicured finger into her pussy, drawing more moisture out. She caressed her fingers through her folds, using the lubricant to meet the desperation of her need for release.
She groaned then bit down on her lip sharply, circling her clit slowly. She lost the grip on her lip and released a deep, guttural groan.
Aaron's ear was attuned to every noise coming from the other side of the bathroom door. Her groan was purely animalistic, the rawest sound a bitch in heat could make.
He pushed through the door boldly, not even attempting to keep his presence secret. He'd decided that he would be fucking this bitch, so there was no need to tiptoe around his intentions.
The woman let out a gasp and stopped herself, but not before Aaron heard the wet retreat of her fingers from her sopping cunt.
His eyes caught sight of her lilac panties hanging on the sink. Exquisite. She would be open and ready for his cock.
"Oh, um," her nervous voice squeaked from the stall. "Sorry, I'll clean up the sink in a minute."
His cock was thrilled by her attempts at innocence. Such fun to play with. He'd make her admit to herself that she was a bitch in heat, in need of a proper fuck.
Aaron said nothing. He stepped into the bathroom, collected her panties and held them up to his nose. He breathed in deeply, losing his last shred of self-control. He pocketed her panties and then stood in front of the only locked stall.
It was quiet for a moment. He could hear only her heavy, panicked breathing. She'd stopped touching herself, but he could smell her heat stronger than ever.
He knocked on the stall door three times.
"Um!" she squeaked in panic. "This one's occupied!"
Aaron grinned and knocked again.
"Oh my god, I'm in here," she was becoming frustrated.
"Don't make me knock again."
Aaron tried to keep his voice playful, but the breeder instincts overtook, deepening his voice to a more assertive tone.
Chastity was silent for a moment too long. She attempted to shriek, "This is a women's bathroom!" in disbelief, but Aaron could hear the new curiosity in her voice.
"Sweetheart..." Aaron began, and he gripped the top of the stall door. He lifted himself onto his toes to see over and stare directly at the woman. She was splayed out, her hungry cunt fully on display. Her shirt was unbuttoned, falling aside and revealing her vibrant bra that barely held her voluptuous tits at bay.
She locked eyes with him but made no attempt to cover herself up.
"I'm here to help you with your situation," Aaron continued.
Chastity hesitated, her chest heaving with deep breaths and her lip quivering. She was battling with herself, but eventually she came to her senses.
"Please," she whimpered.
Aaron gave the door a firm and insistent shove, breaking through the flimsy lock. He wasted no time.
