His boss looked briefly like she was going to ask him if he was ok, but she only said, "Ok, well don't stay too long. See you tomorrow," and she disappeared behind the wall again. He let out an exhale of both relief and intense pleasure, the thrill of almost being caught arousing him even more.
"That was close," she whispered, grabbing his shaft with a fist.
"Now that we know we're alone..." she trailed off and he felt her grip the band of his boxers and pull down. He lifted his hips slightly so his pants could slide down, exposing all of his cock and releasing his balls from behind the fabric.
She grabbed his shaft again with more authority now and brought it to an angle that suited her. She took the tip in her mouth again but didn't stop there this time. She took as much in her mouth as she could, holding it all in and moving her tongue side to side.
"Fuuuuuuck," he moaned.
She reached between his legs and grabbed his balls as she repeated her technique, slow and long sucking on his dick. She wondered what his face looked like right now, but enjoyed being hidden. Up and down on his shaft with her mouth, saliva running down his thighs and into her hand where she still fondled his nuts. She decided it was time to take advantage of all this spit and brought her other hand to him, this one on the base of his dick. She moved her mouth back up to the tip, now sucking hard and faster on his head. She was pleasing him three ways, with her mouth on the pleasure point, one hand stroking his shaft and the other caressing his balls, as if she were begging them for his cum. And she was. She wanted his warm load in her mouth, and the thought of it only made her work harder. She took her hand off his cock to take him all in her mouth, working her head up and down to get every last inch in her throat. She slid it out only to force her head right back down again, this time reaching up to find his hand and bringing it down underneath the desk. She could feel him getting close, taste the precum in her mouth. She put his hand on the back of her head and motioned for him to move her head back and forth. She wanted him to face fuck her, and he always gave her what she wanted. Squeezing his balls more forcefully and the pressure of her lips was all she was in control of now. He had his hand on her hair, pulling her on and off his dick while also moving his hips back and forth. She knew it was time.
Above the desk, he held his breath and briefly looked around, even though it was pointless. He couldn't stop now even if the CEO came around the corner. She had brought him to his peak and he was going to reward her. He slid his other arm under the desk and took her head in both hands, holding it in place while he fucked his final strokes into her mouth before exploding. His thighs tensed as he began to cum, feeling nothing but euphoria and her lips still managing to move around on his head. He continued to hold his breath, which was the only way to keep from crying out in pleasure.
She felt his cum hit the back of her throat and his cock pulsating. If it was possible to smile with a mouth full of dick, she would have, being pleased with herself and the feelings she knew he was having. His hands still held her head steady as his humping slowed. She sucked gently, wanting every drop of cum out of him before she pulled away. When he dropped his hands to her shoulders, she slid her mouth down his shaft one more time, then moved her head back and swallowed his load. She made a satisfied 'Ahhh,' and wiped her mouth. She took a second to appreciate the risk she had just taken for him, then crawled out from under the desk and stood up. On her feet, she could see over the cubicle walls and looked around to see if anybody was within earshot.
Convinced they were alone enough, she sat on his lap with his dick still out and said, "Still want to do away with these desks?" and smirked at him.
He didn't say anything. Instead, he just looked at her with infatuation, put his hand on the back of her neck and pulled her in to kiss him. He put his lips on hers and let his tongue fondle hers, being totally lost in her. She pulled back and smirked again.
She got to her feet and started to walk away. She turned back and said, "Put your dick away, we're at work!" and went to pack her things.
