He takes the panties to the bathroom

As the days goes by, he notices how often Erica walks by his office door. He also notices how she smiles at him whenever he looks up at her. He heads to lunch with some of his teammates to discuss their new project, but he can’t keep his mind off the panties in his desk drawer.

When he gets back from lunch, he checks the drawer again. The panties are still in there, however, there is also a yellow post it note is stuck to the front of them that reads, "fill my panties with your cum and I'll be back for them."

After reading the invitation to masturbate over them his cock is straining against his pants. He heads straight to the men's room, locks the door, spreads the panties on the counter, and drops his pants, releasing his hard-on.

He is just about to jerk over the panties when he has an idea. He takes his phone out and props it up to film himself.

He strips naked, puts the panties on (remembering what Erica told him about her ex), and starts recording. He plays with his cock through the panties, stroking his erection through the thin cloth. He slowly takes the panties off and holds them hanging in front of his penis head brushing the tip. Then he masturbates until he jerks a hefty load of cum over the pink satin. He carefully folds the panties, puts the in his pocket and hurries back to his office. He returns them to his desk drawer to await the owner's return. He doesn't have to wait long.

Toward the end of the day he is sitting at his desk when he see Erica strolling through the office. That day she is wearing a white blouse and a dark blue business skirt down just below her knees. She comes in his office and sits on the swivel office chair next to him. She crosses her legs which pulls her skirt high up her bare thighs.

Erica leans forward, opens the drawer, and pulls out the panties, soaked in his semen. She spreads them out and smiles as she studied the big splash of semen on the front triangle of pink cloth then puts them back in the drawer.

"Looks like you enjoyed them," Erica says.

He doesn't know what to say, but before he can say anything Erica smoothly uncrossed her legs and spreads them wide, pulling her skirt even higher up her thighs. As any man's would, his eyes go down. He can see Erica's naked mound. Spreading her legs, she pulls her pussy lips open. Her lips are ringed with blonde pubic hair and her labia are peeping out glistening pink.

"Shall I put my panties back on or do you like seeing me like this?" Erica asks. He is still lost for words, but then she says "I wish I'd been there to watch you shoot your load."

That time he knew exactly what to say. He picks up his phone.

"I can show you if you want," he says.

Erica moves in closer to him. If anyone has seen them, they would has assumed she is looking at his screen to see how his project is doing. It takes just a moment to link his phone to his computer.

Then there he is on the screen, from his chest down, naked but for Erica's pink panties. His hard cock is pushing the tiny front triangle out in a big cone showing the outline of his hard shaft and big round head through the thin taut pink cloth, with his balls and pubes showing at the sides. He flicks the top hem with his fingers and his straining shaft springs out at the front so his hard-on poked up high above the waistband.

Erica gasps, and her hand goes down between her spread legs and she begin to rub herself.

On the screen he slips Erica's panties slowly down and posed with them just below his hairy balls, thrusting his hips forward to show off his hard upright erection towering above the pink cloth. He fingers his penis and balls and flicks his stiff shaft before he takes the panties completely off. Erica watches him play with her panties, hanging them on his cock, stroking them over his dick and running them over his balls and between his legs.

As he plays with her panties Erica reaches out her spare hand and touches his thigh. He swivels his chair toward her and spread his legs. Her hand goes straight to the bulge of his penis through his trousers. He is hard erect and she gently strokes the ridge of his shaft.

"Get it out for me!" Erica whispers excitedly, "There's no one around to see us."
