Assistant Lab Rat II - Bust Enhancer Tinkering (Pixiv Fanbox)

Hello, Hexxet here, This one is a commission from Kurt who was interested in a continuation of "Assistant Lab Rat", but with a focus on the gadget only introduced at the end - "The Bust Enhancer"! This story is dedicated to perfecting this device and of course to very big breasts and their transformations :). The comic is 117 pages long with 9 pinups. Plot: James has Stacey work on the Bust Enhancer to fix the kinks out of the device. Julie is supporting her mother with that since Stacey is quite handy-capped with her two super sized beach-balls while working ;). They have captured a new test-subject (Nicole) and are now trying out the Bust enhancer again and again until they hopefully get it right :) Contains huge traces of Breast expansion and my kind of humor ^^ I hope you enjoy this story! :) PS: Part one of this series is long ago and only available in my Gumroad-Shop.
