"I want to taste your cum Doctor Giles! Please cum in my pretty little mouth."

"I want to taste your cum Doctor Giles! Please cum in my pretty little mouth." Madeline said luridly as she looked back at Dr. Giles.

His eyes widened as he heard her plea.

"Fuckkkkk ahhhhhh! I'm....ugh....I'm gonna--" He said as he thrust harder and faster, taking in a deep breath as if preparing to cum. He thrust one last hard good thrust then used the momentum to pull out of Madeline.

A younger man might have cum some inside of Madeline (not that it mattered with her Birth Control vault implant) before he had pulled out. But the older doctor at least had some self control, or maybe it was just slower gusto.

Madeline sped to her knees and put her mouth on his cock. Just in time too. She barely had her mouth on his head when he exploded inside of her mouth. His warm goo shooting deep inside of her mouth in surprisingly large volume. She swallowed the first gouts with practiced determination, even putting her hand to his head to help usher his final volleys of warm juices.

She tasted herself on his shaft after she had swallowed his load.

"UGHHHHHHHHHHHHH! AHHHHHHHHHHHHHHHHHHHH" he let out almost a whimper as she finished him.

He took in a few deep breaths in rapid succession. He was old and he hadn't cum like this in a long time.

"Fuck!" He said in ecstasy as Madeline pulled off his cock. She licked her lips darkly.

"Mhmmmmmm, you like that Doctor Giles?" She said with coquettish fervor.

"Oh my God..." he said panting "You are a slut. Jesus Christ."

"Yes Doctor Giles," Madeline said "But I am your dirty little slut." She gave his quickly shrinking cock a final long suck. Giles' eyes nearly bulged out of his head as he was unexpecting that.

"Oh!GUH!" he moaned with pleasure and sudden excitement.

Madeline pulled off and stood up slowly, letting Dr. Giles recover.

They both zipped up their clothes.

"I can't wait for guard duty tomorrow." he said as he grabbed his rifle and put on the act of looking around to see if anyone had heard their escapade.

Madeline smiled, was she being slutty or was she putting on the act...Ward didn't know she had made this deal with Giles, but Giles didn't know she had the same agreement with Ward. Best if they didn't know.

"Oh I am sure." she said teasing "Well, I'm getting some sleep." and with that she walked back to their camp, Dr. Giles' eyes following her closely.
