The comic "Remote out of Control" is a bit short, but well worth its money for its IB content in part 2. It features the all-too-rare plot of two teenage girls getting a universal remote and simply using it to improve their bodies. Although all processes occur off-panel except for the BE, it features hair lengthening, weight loss, BR (from huge to manageable), facial IB with thinner nose and prettier eyes, slight hip expansion and possibly a little AP (maybe from high school to college age). One girl gets minor improvements besides BE, while the other gets a complete makeover.
The remote also has a "horny" button and an "orgasm" button which get used several times.
Despite being hosted on Bimbo Story Club, none of them have gotten stupid (yet).
