Just wear a chastity (can be all male, sissy or shemale) when dosing her, when she gets the blowjobs dose you get the chastitybj, when you give her the fuck dose she instead strap-on fucks you on the couch. The chastity also changes the the weekend evening sofa activity significantly as well.Was going through the media folders. Surprisingly, or not, imo, dakota has the largest file, comparable only with ava. What's even more interesting was the presence of files like chastitybj.mp4 Pretty slef-explainatory. The question is, did anyone unlock anything along those lines in the game??
If you don't want to buy a chastity, Diana will automatically put one on you if you run out of stamina while pleasing her (ask her "does she have any ideas" in her office then wait until she comes back), you'll wake up with it on, second go while already caged you wake up with a plug up your butt as well. Plug can also be given by/taken from Tasha after spying on her. Note chastity can only be removed in the sexshop, and it will affect your body transformations, so lock gender if you don't want it to change you (potentially all the way to female, if you become limp-dicked sissy that's actually the only way to change back, go female, wear strap-on + male clothes all the time, then back to shemale).
