Wow, thanks for the comment and the rec on TWoP (I'm assuming that was you). I'm so happy you liked the theater atmosphere - shady but not dirty is exactly what I was going for.

I didn't think I had a "first-time" in me, but somehow it just fit the setting.

I wondered whether the ultrasound simile would be too detached; glad you thought it worked. (Really I just wanted someone to spit after a blowjob for once.) Thanks again!
