A/N: This popped into my mind and I figured writing it down.
"Come on," said Santana. "It'll be fun."
"Maybe if we went somewhere private, but not here." Santana and Christopher sat at a table in the library. It was almost empty, save for them and the librarian, who sat at the front desk.
"That's what makes it fun," said Santana. "Look, she won't even notice."
Christopher peaked at the librarian. She was busy reading papers. "I don't know."
"Fine, fine," said Santana. "If you don't want to do it, I won't force you to."
"Thank you," said Christopher.
"Hey, what do you think Puck's doing right now?" said Santana.
Christopher rolled his eyes. "You know what? Let's do it."
Santana grinned. "Are you sure?"
"Yeah, I'm sure. You made it sound fun." Without further ado, Santana shimmied under the table, shaking her breasts playfully as she did so. Christopher turned back to the librarian. She was still reading her papers. He could feel Santana's hands making their way to his zipper, followed by the sound of it being unzipped. Santana's fingers slipped under his jeans and pulled down his boxers. He was impressed with how fast she could do this. Her movements were so smooth, like she had a lot of practice.
He felt her warm breath on his thighs. His hearts raced in anticipation. She waited, continuing to breathe on him. How long would she tease him? The longer she did this, the more likely it was for the librarian to look up and catch them. Finally, Santana grabbed his shaft. Her delicate, soft fingers wrapped around him. She began pumping slowly and deliberately, as if she were trying to savor every second. Christopher felt a tickling sensation on his balls. He realized Santana was doing this to him with her other hand. He gasped in surprise. His heart skipped a beat. Had the librarian heard that? He glanced at the front desk. She was still there, reading. He pretended to cough a few times, trying to disguise his gasp as a coughing attack. The librarian didn't react either way.
Santana lifted his shaft and Christopher could feel her tongue running up from the base and to the tip. It moved slowly, teasing him. Whenever she got to the tip, she would tickle it with her tongue. She continued to lick him, each time moving slightly faster each time. After the third or fourth lick, he stopped feeling her tongue. It was replaced by the sensation of her breath on his tip. He bit the inside of his mouth to stop himself from crying out as Santana's lips slid over his member. She didn't do that quite yet. First she lapped at the tip with her tongue. His balls started to ache. Finally, she wrapped her lips around his member and began to slip it down her mouth. He could hear her practically choke as she forced it into her throat. He worried that this would be what got the librarian's attention, but she continued to read.
Santana's hand and mouth worked in tandem. She stroked him off as her mouth moved up and down his member. Her hand seemed to move faster, no doubt lubricated by her saliva. Her head whipped back and forth feverishly. He could hear slurping noises as she slobbered over him. Suddenly she stopped at the base. Christopher began to feel her throat tighten. This was no doubt a vocal exercise she picked up from that singing club. Her throat muscles closed in snuggly over his member. It was so tight that Christopher couldn't help but let out a moan.
This got the attention of the librarian. As she looked over, Christopher began to cough. She raised an eyebrow, but turned back to her desk, seemingly none the wiser. Then she looked up. "Where's your friend?"
"My friend?" said Christopher. As this was going on, Santana still had his member in her mouth. He struggled to talk naturally. Everything came out like he was out of breath.
"The cheerleader," said the librarian.
"Oh her," said Christopher. "She...she went to the bathroom."
"The bathroom?" said the librarian.
"Yes," said Christopher. "The bathroom."
The librarian continued to glare for a few seconds and then got up. Christopher's heart raced. She was going to come over there and spot Santana. But this didn't happen. Instead she walked out of the library. As the doors closed behind her, Santana tickled Christopher's balls. This was enough to set him off and he shot a load into Santana's throat. He heard a gulping noise and Santana got up from under the table. Christopher rushed to zip up his jeans. "You're lasting longer."
"Jesus that was close," said Christopher.
"Don't you guys have some kind of rule about taking the Lord's name in vain or something," said Santana.
"We can't do that again," said Christopher. "We almost got caught."
"But wasn't it fun?" said Santana.
"Fun?" said Christopher.
"Yeah," said Santana. "Wasn't it exciting? Didn't it make things sexier?"
"I guess," said Christopher.
"There you go," said Santana.
"Hey, can I ask you a question?" said Christopher.
"About what?" said Santana.
"About Puck," said Christopher.
Santana smiled. "Don't worry. Yours is bigger."
"Really?" said Christopher.
"Oh yeah," said Santana. "It's not even close."
