Superstar in the Lab (Patreon)

Cody trembles as the machines work on him, unable to resist the evil doctor's commands. The teen hero gasps as he feels another needle slide slowly into his nutsack, injecting him with more experimental serums. Other devices spread his already gaping anus, and Cody closes his eyes, preparing to be brutally fucked by the tentacles once more.

Part of a series I'll put together as a comic sometime next month.
