This is a Loader Mod for the Super Deepthroat (SDT) game.
When loaded, it causes a lipstick-colored "kiss mark" to appear on the male character's body.
Five separate marks are included in this package. They can be loaded successively (via individual MOD files) or simultaneously (via the combined MOD file).
Flash modders can find the source file on mega.nz. Normal users can download the 7z archive (containing the MOD files) via the link at the top of this page.
