Hey. Your game is cool and I have idea for 2 characters.
Rena:
She is a huge spider-woman. She is a fitness trainer, you can training with her what increase you strength and stamina, but have 33% chance for AV. Because she accidentally sit on you then you do exercise. Training costs 20 and always spends half of stamina. She has OV then you ask her, UB at 50% relationship ( if you stay 5 days she will pay you 60). And she will digest you in 2 days, but it will be difficult to get out on your own, but starting with 50 percent of the relationship, she will always let you out. To escape you need to struggle 13. To increase relationship you can give her presents (5) and training (2).
Sira
