Lovense is an adult toy company, the sex toys they sell are "linked" to devices like phones for exemple.
In the case of karryn's, it would mean something like, when she gets fucked, your butt plug would vibrate or something like that.

Is that something guys do or the game is just really popular with girls?
Ehem so what was I...
I think in November there were news saying that "they would be announcing Gym dlc now but due to feedback they need to work on it more" - more or less. It's been 4 months and don't seem to be any news regarding that DLC? In the 1.2 news they talk about stray pubes dlc preparation ... where did the gym go ?
The game was finished in 2,5-3 years if this thread creation to be of indicator. Taking over 1 year for DLC because they need to redo the code and stuff is not good. it would be more efficient to work on new game instead ...
