The AI knew exactly what to say to push his buttons and turn him on, and it was perfect, bittersweet frustration.


Tyler wakes up surprised. He’s still bigger.

Getting used to his new, huge body. And the changes aren’t just physical…

The email from the protein powder company.

The AI “assistant”: The Master explains the power of the protein powder, the nanites.

Lots of instruction.

Dylan, the delivery driver from book one. He is cool and sweet.

“And you’re a bottom? This can’t be real.”
“It’s real.”


All of the AI’s demands and “preparations,” but none of them include anything for actual bottoming? Like…lube, for starters?

The action is quite mechanical.

Rather dubious overall, though the ending has some promise.


“That was incredible.”
“That’s an understatement. This was the best delivery of my life.”
