She doesn't like wasting time

"Oh fuck." you exclaim, spent and in ecstasy by what happened.

"You may be asking yourself why I just had you jack off in front of me. Trust me, it is purely professional. Like I said, I don't like wasting time, and I can assure you that it is much faster for me, Kelly, to be commanding you to jack off than waiting 20 minutes for you to do it in a room by yourself. This is much faster. She closes the door and leaves with your sample of semen.

A few minutes later, she's back, but a little flustered. "Dammit, there wasn't enough sample to complete a full analysis, we're going to need more."

You feel spent, and start to protest.. "But.."

"Shut up, remember what I said." She pulls out a syringe out of the drawer and loads it with a clear foggy fluid.

"Hold out your arm, this will help you recover quicker."

You reach out. Then she pauses. "Second thought, turn around." She pokes you in the butt and you feel the pressure of the fluid going in.

"Much faster." She says satisfied.

She goes back to the countertop and starts organizing some papers.

Sitting there naked, within a few quick minutes, you feel your erection start to grow and return. It feels much harder and full than the first time.

"Uhh... Kelly," you say.
