Oral/facefuck

He then undid his belt and pants, pulling out his rock-hard cock and stroking it, as it was pointing right at her.

"I'll need to test out your oral capabilities. I want you to suck my dick," said the Doctor with a commanding tone.

"Okay, Master," said the robot obediently, as she got up from her seat and walked over to him.

She got on her knees and leaned her head forward, wrapping her mouth around his throbbing member, and began to gently suck on it. The Doctor let out a groan of pleasure as Betty started to blow him.

"Ah, that's it. Now I'm going to face fuck you," said the Doctor, as he grabbed a handful of her soft, blonde hair and began to roughly thrust his cock in and out of her mouth.

"Mmmph, mmmmm!" Was all Betty could say, as he roughly fucked her face. She could handle it, since she wasn't made to have a gag reflex or need to breathe. Also, she enjoyed this treatment, finding that her body was reacting to the rough treatment.

The Doctor groaned hard as he rammed into her mouth hard. "Ahh! Nearly there! Get ready to swallow every last drop!"

"Mmmm!" Moaned Betty, as she eagerly waited for his load.

The Doctor then threw his head back and groaned hard, as he came hard down her throat, releasing a large amount of cum inside her mouth. "Ohh! Fuck!"

She eagerly swallowed it, and she felt a strange sensation. It was a feeling of warmth in her belly. She had no idea what this was, but it was a good feeling.

The semen would be stored in a small, special storage container that was located inside her and could either be emptied out later or kept as a form of backup energy.

"You have done a very good job. How did you like it?" Asked the Doctor, as he looked down at the robot.

She was made to enjoy it so long as he enjoyed it.

"It was good, Master," Betty replied. "I'm ready for more, if you want."

"Excellent," said the Doctor, as he rubbed his chin and thought for a moment.
