A few folks

Kiara and Mark slid their college ID’s into the machine, and walked into the library.

He looked down at her photo ID. “I guess I don’t have to ask how you got one of those?”

She smiled. “Okay, we’re going on a tour. Let’s start with that rare book room you mentioned.”

“That’s locked,” Mark said. “You can’t get in.”

Kiara rolled her eyes at him. They walked down the stairs and to the entrance to the rare book room. She stuck her thumb into a scanner, and the door popped open. “Stay quiet.”

They walked past rows of old books, behind the librarian’s desk, and to a short interior hallway. Kiara nodded at a shut office door. The curtain on the door’s small window was half open, and Mark could watch very clearly as a young man wearing a tie and button down shirt—the librarian?—stood next to his desk. He was rhythmically thrusting his cock into the mouth of another young man, who was wearing gym shorts and a t shirt, and leaning on the desk for support. Mark was intrigued. He’d never seen gay sex in real life.

They watched for a couple of minutes, before Kiara motioned them out. “He’s about to cum, and he’ll then get guilty and look around.”

As they left the rare book room, Mark said, “OK, that was cool, though it was a little gay for me, even after last night.”

Kiara smiled. “That was a warm up.”

They took the elevator to the 4th floor. Along one side of the floor were a series of enclosed study carrels. Kiara led him down to about the 10th carrel, which was empty. They entered. Mark looked at her. “What?”

Kiara made eye contact and lifted her eyes. Between each of the study carrels was a wall, and at the top of each wall was an 18 inch high pane of glass. Mark pulled over a desk chair, and climbed up to see what Kiara was referring to.

Below him was a young couple. They’d covered with paper the square of glass on their carrel door and thought they’d gotten a little privacy. She was squeezing his dick through his jeans, while he’d pulled up her polo shirt and bra and was licking and biting a wide nipple. They were both in great shape, and obviously totally absorbed with each other.

Mark felt his cock rise, again. He watched the man try to unbutton the girl’s shorts, but she swatted him away. The girl unzipped her boyfriend’s jeans, pulled him out, and lowered her head while he pulled on her nipples. That girl, Mark thought, knows her way around cock.

Mark unzipped himself and pulled out his own. He’d need a new technique with his improved model. He started tugging faster and harder. He could feel the familiar pre-cum tingle.

“Ok,” Kiara said. ”You’re about to make a big fat mess, and I didn’t bring any Kleenex. I think you should zip yourself up, and you should go meet Cindy.”
