Climb on top.

He was close to cuming, but Madeline needed to ensure she had a position on the expedition. She slowed the movement of her head on his shaft and moved her mouth into a few long slow strokes before pulling her lips off his member.

“Now Overseer,” she said her cock near her mouth looking into his eyes “I will let you feel inside me if you will let me on that expedition.”

“I uhhh I uummmm.” he stammered, not having words for the moment.

“Overseer McIntire,” Madeline said standing up unzipping her vault jumpsuit “I know you have always wanted to know what it would feel like to be inside of me.”

As she undid her vault suit her cleavage was revealed wrapped only in a retro style bullet bra. Overseer McIntire eyed her breasts, as he had many times before though this time he got to see them up close and nearly uncovered. Madeline had been the most well endowed young woman in the vault and his eyes especially lingered.

She undid her bra, letting it fall to the floor before climbing slowly on top of the Overseer.

Almost unconsciously his hands moved to her breasts. They were massive, and her nipples were hard as diamonds from all the excitement. Madeline could hardly believe she was doing this, but she had to get out of the vault. She would do anything.

She reached down to guide him inside of her. She found she was already wet, a pleasant surprise, maybe sucking cock had been more exciting than she thought. Maybe it was just the rush of trying to seduce a man. It had been some time since she had had sex and she bit her lip slowly as he moved deep inside of her. She pressed her body against him, her breasts touching his exposed chest as he moved his hands to her hips, titillating him with numerous pleasures all at once.

She moved up and down on him, her legs pushing up off the floor and back slowly to engulf her womanhood with his member.

“Ohhhhhh Oh ohhhhhhhhhh! Oooooooooo!”He moaned with pleasure, very loudly. He remembered his surroundings and tried to muffle his joy. His hands moved hesitantly over Madeline’s body nearly too rapt for pleasure to do much of anything.

It doesn’t take long for her rapid movements up and down, down and up to cause him to suddenly spasm and his legs to stretch out as his cock throbbed with a jolt.

Madeline felt her pussy fill with warm fluid. A pity she didn’t even have time to get off. Madeline didn’t stop but continued for a few short and powerful seconds carrying his ecstasy even further. She wasn’t too worried about the unprotected sex. All females were given a birth control implant in the vault to regulate the vaults population, it would be years before she could bear children without the plant being removed. Madeline found herself moaning slightly at the end. And while he did not bring her to climax, it wasn’t about her.

“See Overseer McIntire” Madeline panted from the exertion”—I know quite a bit about the human body. I believe I can use such a skill on the expedition. Wouldn’t you agree?”

“Yessss” He squirmed in his large ornate chair “Yes….I believe so Madeline….” He panted with a sigh of pleasure as Madeline slowly moved off his cock, a torrent of cum trickling down her inner thigh, the handy work of the Overseer. It plopped down on his chair but he could care less, being wrapped in a feeling of pleasure and excitement he hadn’t felt in years.

“I look forward to more details on this mission.” Madeline said with a smile as she zipped up her vault suit. She could clean up later.
