He figured nothing of it...

Mark was a realist, he knew there was absolutely no chance that he was going to receive a $50k check and then be whisked away, molded, surgically and hormonally altered, maybe even medically, and by an off chance magically, into a 20 year old sissy-bimbo who looked like Alexa Bliss on an Amazonian 5'10" frame (6'4" in stripper heels). He put it out there to make his fantasy theoretically possible and therefore his jerking off, more than just headporn. Not much more. Buy you can't win the jackpot if you don't play the lotto. Just as he was contemplating whether or not to break out his small thrusting buttplug. His notifications pinged. It was a response, a super quick response.
