about the toys. When you put a cage (in dialogue), the plug is disappears from inventory and vice versa.
Edit: if you buy those toys, you can wear or remove it from them. And toys dissapear from inventory after simulation of days. But how to get money to your sissy's balance, if it has only 2$. Play games and lose to her is too long...
Edit 2: if you lose to your partner in game, if their bet are some status, I can give them money as many as I can (before 20000)
