Welcome to Versions 10 & 11 of "The Klub 17" ("TK17" for short). Latest version: v11.0.10
TK17 is a free easy-to-use "sex-simulator" that allows you to construct your own custom models, apply custom outfits, design animations ("Poses"), and test them in dozens of locations ("Rooms") to create your own adult movies (aka: "Sequences"). Officially, TK17 is movie-maker software, but most users enjoy simply playing around with the individual components. There's even a "QuickMode" just for fun that loads your model into a randomly selected room waiting to play with you.
"V11" is the new (64bit) release of TK17. It fixes many bugs found in VX plus has dozens of added features & improvements, and none of the memory limitations of 32bit VX, allowing for "room chaining" in the Sequencer and higher resolution textures (Note: the popular 32bit graphics enhancement "Hook" is incompatible with 64bit V11).
Thanks to the efforts of a robust modding community, there are literally hundreds of custom outfits, locations, poses/animations, even custom voices, available for download all for free.
