In Lona RPG so hard to escape after fucked and captured by any creature, and I haven't stealth and slut stats at all.
I think 3-5 SCU are a must. Not only for most quests, but also to escape random encounters.
For escaping after getting fucked:
-get full stamina (important!)
-get naked (so you don't drop and lose equipment)
-lure one enemy away from the group, to the map border if you can
-use the "surrender" skill
-get fucked once and run away the moment you get control back (depending on your stamina you can let them fuck you again if the first time wasn't vaginal)
You can use blue potions and get yourself fucked into red stamina, but that's more expensive.
