She doesn’t get a chance to choose.

Before she could hear a response, she was thrown to the ground, as Hyatt grabbed her hips, turned her over, and pulled her ass into position. He laughed when he saw the plug.

"Better pull that out, yourself, slut. Last chance."

She struggled up to her hands and knees, looked up to find her instructor nodding and mouthing, "Say yes." She dropped her head, reached back behind her, grabbed the plug, and pulled. The gel covering her disintegrated as she did so, and she shivered as the air moved over her now truly naked skin.

She felt a drop of spit land on her ass-crack and drip slowly down. She stared at the ground; Hyatt rubbed the spit in with his cock, then pressed in, slowly at first, reveling in the feeling.

“aaaaaaAAH OW! Oh that hurts!”

Scarlett couldn’t think straight as Hyatt kept the pressure up, and the pain mounted. She tried to crawl forward to get away from it, but bumped into her instructor’s knees. Hyatt quickly reached the depth the plug had been in, but had barely started—every time she thought he might stop he just paused and pushed further.

"Oh, god, Ow! Hnnnngh! Oh fuck!"

Tears were streaming down Scarlett's face when Hyatt finally bottomed out with a grunt.

"Damn, I forgot how good an ass-fucking can feel. Been in that vat too long, right boys!?" Hyatt asked, to whoops and cheers.

Scarlett looked up and saw, through a curtain of her hair, that some of the crowd had pressed closer, and someone was high-fiving Hyatt. Her ass felt like fire. She turned back to the man whose instructions had led her to this point, pinioned on some stranger’s penis, more men crowded around her like hyenas circling a corpse.

“Please...it hurts.”

“Yes, toy. It always will.”

“Please make it staaaaaaAA—” Hyatt had finished his high-fives, and was starting to fuck her in earnest. Her instructor moved his legs apart and let Hyatt’s thrusts push her face into his crotch.

“Good, toy. You’re doing a great job.” He patted her head, gently, then put his hand around the back of her head and pulled her forward, her face pressed against a large bulge under his trousers. “Unh. I think you deserve a reward.”

She didn’t see what happened, there was no unzipping or movement that she could see, but suddenly his cock sprang free and smacked her in the forehead, leaving a spot of pre-cum. Most of her attention was still on the raw friction tearing her ass, but she was **** to look up as her instructor pulled her hair back.

“What do you say, fuck-toy, when someone offers to donate to you?” His voice was harder now; the gentleness that had been there was ebbing away. Had she done something wrong?

“Oh, ow, uh, please? Please, sir? Ah!”

He laughed. “Sure, that’ll do. Now say ‘ah.’”

“Hu—ack!” Dispensing with any additional instruction, he maneuvered her mouth over his cock and plunged as far down as he could get, meeting her gagging throat almost immediately. He held her there for a second, enjoying the panicked vibrations coming from her vocal chords. He let her come up just enough that she could suck in a ragged breath, and watched her spit flow down his genetically-enhanced dick as she coughed, then methodically started pumping into her mouth, forcing her to gag every time he got too deep. Her eyes were closed, and her hand would occasionally weakly press against his knee, but for the most part she was silent as he and Hyatt spit-roasted the poor slut. They grinned at each other.

Scarlett couldn’t process the sensations she was being subjected to. Every time she tried to think about pushing herself away from the pain in her ass, her mind was **** to try and breathe around the intruding phallus trying to find the entrance to her throat; every time she thought she had her breathing under control, the cock behind her would thrust into her defenceless ass, causing yet another spasm of pain.

Among the crowd of young men—old men in youthful bodies, really, endowed with both patience and vigour—many sensed that it would be a little while before Hyatt and his friend relinquished their toy, and made their way back to their seats elsewhere on the bus. Others, perhaps those only on their second or third cycle, stayed and watched the pretty young woman trapped between two cocks, her tits swinging, spit dripping down her chin, squealing in pain when she could, gasping or **** for air whenever the man in front of her drove into her mouth. Not one seemed in the least concerned at her obvious distress.

Finally, after what seemed an interminable time, Hyatt's pace increased, and, with a grunt, he flooded her ass with an extraordinary load. The semen actually soothed her pain for a moment, before beginning to cascade down her thighs as he pulled out and wiped his softening cock on her back. Her legs collapsed as he let go of her hips, dropping her back into a caricature of her former position, her head still being used by the cock in front of her. Not long afterward the cock abusing her mouth exploded, too, but she was too addled to swallow more than a tiny amount of the cum fountain. Most of it dribbled down her chin and onto her bare chest.

When her head was finally released, she gasped and coughed and gargled for air, and sank down onto the ground, covered in spit and semen.

"I gave you two simple rules to follow, slut. Can't you even do that?"

When could she wake up from this nightmare? When would her body stop hurting? She looked up at the man above her.

"I told you to say thank you whenever a man is generous enough to donate to you. Where is my thank you?"

"I—I'm sorry. [cough] Thank, thank you, sir."

His demeanor changed as quickly as if she had hit a switch. His expression softened, and he said, "Good, pet. Good. You've done well."

"But pet, don't forget, you need to swallow your medicine. You can't just let it dry on your tits like that. Where's your dose extractor? You have two doses to drink! Pick it up and collect them."

Scarlett sat up slowly and found the device where she had left it. What was she supposed to do with it? She held it tentatively against a puddle of fluid collecting around her belly-button, and felt the filters engaging as the extractor did as advertised and somehow separated the cum from her spit. She moved it up her chest, watching sperm collect in the clear container. When she had traced all the wet spots around her breasts, she held it dumbly in the air, looking at the viscous cream swirling inside.

"Hasn’t anyone shown you how to use this? Turn it around. See those numbers there? That one shows the quantity. So you've got a little less than half a dose in there. You're pretty young, so you probably only need 15 or 20 doses a day to keep your mind stable, though that'll go up over time. And that number shows how many different donors have contributed to that load. You should probably try to have as many donors as possible. Obviously it only says one right now, but once you get the contribution from your ass, it should say two."

He looked at her expectantly. With a defeated cough, she leaned over and maneuvered the extractor around to her butt, wincing as the cold device touched her raw skin. Again, she felt it working, but evidently not quickly enough for Hyatt, who grabbed it from her and slammed it unceremoniously home, eliciting a sharp cry of pain.

The man to her left continued.

"Now, pet," he grabbed her hair and **** her to look at him, "you're not quite hopeless, but you're pretty close. Out of the goodness of my heart, I'll consider providing you some tutoring at Phucker—“

“Oy, loverboy! You wanna finish up with the co-ed? Pass it over, then, eh? We’re fit to burst, here, and she’s got the only holes on the bus!”

Hyatt stood up immediately to face the 5 or 10 men still watching. “You’ll get yours soon enough, dude. Just let my friend finish up and we’ll pass her over. No need to get testy.”

The crowd subsided slightly, but Scarlett thought they still looked like they were spoiling for a fight. Well, spoiling for something, anyway. She’d always thought it would be kind of romantic to have men fight over her, but this was not what she’d had in mind. This didn’t feel romantic.

“You almost done, Francis, or do I need to wake the twins up?”

She hadn’t even noticed that the two men next to Hyatt and Francis were both asleep. How could anyone sleep through this? Was her situation so commonplace, her predicament so boring?

The man above her pulled her hair again to focus her attention back on him, and continued, “Looks like I have to let you get to work. You’re in high demand! I’ll leave you my name. Come find me on campus, and if you seem like you’re worth my time, I’ll consider training you.”

He took what looked like a small piece of metal and pressed it against her upper arm. She felt a quick series of pinpricks and when he removed his hand she saw what appeared to be a line of text tattooed on her skin.

"It’s alright, Hyatt. Sit down. You, what’s your name?"

“Name’s HomeDepot McDonald’s. I usually go by Homer.”

“Ok, Homer. Sleeve here is under my protection for the moment. No permanent marks, understand? Pass it on.”

“And who the fuck are you?”

“Francis Donatien.”

The man in front of the crowd looked hard at Francis, and seemed to deflate slightly.

“Fine.”

"Now go on, pet. Get to work."
