For the full bunny you need to have sex with the rebels in the hideout. The forest shrine is just to level up stats, so don't worry about that one. You will get better ways to do it
For some reason eventhough I had both dom and sub sex with Ashton rebels and did the nighttime sex training....the suit did not show up. Now that the trainer is gone, I redid the sex scenes. It did not say I was rewarded the suit but I now find it in my inventory. It is a mystery haha. Thanks for the tip.
