Big Tits makes a last appearance

There was a young girl waiting for him. Ben felt a stirring downstairs. Yum. She had a sweet little face, with crystal blue eyes. She was quite petite, and from what he could gather, her breasts looked completely edible.

"You got **** to?"  The girl looked at him with no change in her expression

"Yes.  Last night I was watching for UFOs through my telescope and suddenly I was aboard their ship.  This is my dream, to meet aliens."

"It's over rated.  They're mean bastards." Ben couldn't believe this girl.  She was excited about being ****

"No, I'm very excited about being part of the experiment"

"Well, that's not so bad, I get to fuck you" at this a wry grin spread across her face.

"Not exactly, in order to extend the parameters of the experiment, they... changed my role in it.  A member of the crew recently passed on, and I was offered a transplant" Oh no, you're kidding me, Ben thought

"Big Tits!??  What's going on?" She stood up from behind the table where she had been seated.  She was totally naked, and Ben could now see an alien shaft hanging between her legs.  "You had a sex change?!?! Sick Freak!!!"

"No, I am fully female, I assure you" She lifted her new member aside to show her pussy.  "I am simply an enhanced human, thanks to alien technology."

"Your bloody nuts, and you're not coming near me." She smiled again and drew a control box.  Ben was on the floor in agony and when the pain ceased, he had been strapped to the bed.

"I'm going to enjoy this..." Ben looked up in horror at the dick descending towards his mouth.  Worse still, his jaw was stuck open.

"OAHAOAHAHAOHA!!!"  He yelled but it made no difference.  The girl **** her shaft into Ben's mouth.  She pushed it in, deep into his throat.

"Oh, this is greeeaaat!!"  She giggled and laughed as she fucked his head.  The gooey alien cock slid through Ben's mouth, and he felt absolutely violated.  The girl spun around, still buried in his mouth and ground her pussy onto his nose.  Somewhere above him he could hear her moaning and panting excitedly.  Screw this!! Thought Ben, and he used his tongue to try and push her cock out of his mouth.  This new stimulation took her over the edge, and she came all through his mouth.  "Aaaaah...  that was excellent."
