0.8.1.5b features a vast amount of new content:

• 150+ renders. Eliana's entire archive is completed with Rachel not that very far behind. I've also upgraded Lovisa's wardrobe and rendered Caitlin's entire (single) morning BJ session.
• Virgin framework. Includes over 5,000 words of unique texts and special renders for the currently available virgins; Lovisa and Michelle. The random slave engine (0.8.2 Alpha) can now also spawn virgins.
• New NPCs. Enjoy Aiko's devoted company, marvel at Dexter's desperado moves or listen to Felix Donnerschlag as he tells you his predictions about Ikaanos' dark future.
•  Bondage framework changes. You can now have two active persons in bondage at the same time, with special scripts and smaller dialogue addons.
• New JoyCum implant available at the Medical Facility.

0.8.2 Alpha content (Tier4+)

• A new slave market in Watery Eyes, ten additional random slaves and roughly 10,000 words of new random slave background texts.
