Bumgartner was already in the front of the room and that was fine by her as she snuck in through a backdoor to the cavernous lecture hall. Most students sat in the first fifteen rows, but Crystal preferred the back rows, practically in the dark where no one could see her messing around with chemical formulas. ECON was a required class and she hated it. But things got interesting when some boys entered the class, all wearing the insignia of some fraternity. Some moved the the front but two sat in the back. Bumgartner started his lecture, but Crystal wasn't focused on him anymore, but the two boys a few rows in front of her.
One looked back at her just as she hiked her skirt up a little and spread her legs. His eyes widened. She pulled aside her panties, still damp from the bus and started to finger herself. As if he couldn't believe it, he tapped his buddy and both forgot completely about ECON. She stood up, quietly and walked over to their row, sitting in the seat next to them. She smiled, purring, and reached over to each's semi-rigid cocks, "Today I'm going to teach you gentlemen about the law of supply and demand. I'm going to demand cocks for my mouth and you are going to supply them."
She fell to her knees and urged the one to the left to move closer to the other one. He obliged and her hand slithered up their shorts, rubbing their balls and cocks at the same time. Right grunted and Left slapped him. The seats in front were just tall enough that if an errant glance from the front of the class came their way, no one would notice unless the looked really hard.
"You boys like this?"
Right stammered. He was harder quicker and she smiled wickedly as she looked down at the gorgeous Asian goddess playing with his balls. Something came over him.
"Suck my cock."
"Okay," she said, helping him unzip his shorts and pull out his cock. It wasn't as big as Left's, but she didn't care, taking as much of it into her mouth as possible. Right pulled out his cock and Crystal stroked it wildly. She tried not to make noise, but it was impossible not to. Thankfully, Baumgartner was in full booming lecture mode. She slurped and bobbed on the frat boy's cock then pulled off, teasing the head a little bit before switching to Left's bigger cock.
"Oooooh," she said, taking only the head in before making it half way down, moving quicker and quicker with each bob. She wanted to take the whole thing but she knew that she would gag, loudly. Instead, she switched cocks again, drooling and spitting on Right's glistening cock, she went to work slurping, licking and gorging herself on his cock. Left stroked his cock waiting for his turn. Right moaned then spasmed. Crystal swallowed every ounce then gulped. She patted his cock gently and said, "Good boy, now to finish with this hog."
She went to work on Left's cock, stoking it as she bobbed up on down in it, licking then slurping. He grabbed her head and slammed it down into his crotch. She almost squealed with pleasure and felt her whole body rack with an orgasm. He held her head down for a long moment and Crystal struggled breathing. For a moment, she thought this would be a great way to go, suffocated by cock. He let her go and she came up gasping for air, drool falling from her mouth. She deep throated him again, almost gagging her each time.
"Cum on my face," she said,stroking his cock. He exploded on her face and in her hair and she giggled. "That's it baby, give me your cum."
"Oh my God," he shuddered. She got up, not caring about the cum on her face and went back to her notes. She didn't know that she'd infected them too, but none seemed to care. Left walked over at the end of class and said, "I'm Chad and if you aren't doing anything tonight, maybe you could stop by the Tri-Alpha house."
"I will be there with bells on...only bells."
