Human escapes from alien prison with her unlikely cellmate.

Christina was breathing very heavily right now, adding to my arousal. My hand moved off her ass and towards her pussy. I slowly pulled her underwear down around her knees, then slid my hand back up her inner thigh. When I reached her pussy, I slowly slid a finger in, making her squeal in delight. Just then, a voice came from outside the room.

"Where's Christina with those final numbers?" Her boss asked to no one in particular.

I pushed harder against Christina, hoping she wouldn't notice, to no luck. She pushed back on me and said "I have to go, we'll get caught!".

I relented, but guided her left hand to my erection, pushing through my pants. "You can't leave me like this" I said with a smile.

She gasped as she felt the size of my cock. At seven inches I wasn't that much longer than many guys, but my member was especially thick. Luckily, my pleading had the desired effect.

Christina smiled and knelt down in front of me. She undid my zipper while I loosened my belt. My cock was at full stiffness from all the foreplay, I needed to come - badly.

"Oh my God" she said as she grasped the full length with both hands. I took her head in my hands and guided her mouth onto my cock. I could tell she was as turned on as I was, as she immediately took as much as she could into her mouth. Slowly, she started working her mouth up and down the length of my cock.

Suddenly, more muffled noises came from outside. Christina pulled her head off my dick with a pop as she turned around. Luckily, the noises continued down the hall. "I have to finish you off" she said to me with a smile.

She opened wide and took almost my entire cock into her mouth in one fluid motion. I had to try my best not to come right there. I gripped her head with both hands and started guiding her the full length, starting slowly but then more quickly. As I got close to coming, I was pounding her head onto my dick and then back off. Christina kept going, moaning into my dick the entire time. I could tell she was as turned on as I was, and that she wanted me to come. She reached a hand up to caress my balls and went even faster . Finally, I couldn't hold out any more and came into her mouth. She did her best to swallow all my cum but since she had no warning, a little dripped out. She giggled and lapped it up with a smile.

We both got ourselves composed and quickly moved to the door. I playfully slapped her firm ass and whispered "Can't wait for tonight".

PART 2.

A few hours later, the relief from our encounter in the file room had worn off. I was back to thinking only about tonight, and what was in store for me. Christina had told me that Bill would be waiting for us at their house around 5:30. Finally it was time to leave. Following Christina into the elevator, we kissed passionately the entire ride down. Walking to our cars, it was all I could do to keep my hands off of her, but we couldn't risk office gossip.

I followed Christina to her place, about a 20 minute drive from the office. It was a small, 3 bedroom house with an average size yard. She didn't have any kids, so once we got inside we wouldn't have to worry about any more distractions like there were in the office.

As we entered the house, Bill greeted us. He offered us both some wine, in an apparent attempt to loosen our inhibitions. Little did he know that Christina and I were both fully ready to go.

"So Dear, it's your birthday - How do you want to get your present?" Christina asked impishly.

"How about you two get started? I think I'll watch for a little bit." Bill said with a smile. I couldn't have asked for a better response from him!

Christina and I moved to each other and embraced.
