High Agility is generally useful, no matter if a Fighter Run or a Slut Run. In this specific case, yes it is extremly useful to act first, since you are able to choose the Sex Position you want. This is extremly important, against 4 or 5 enemies, since there is currently only Titjob Position, that can deal with up to 5 enemies at the same time. That means, enemies are going to cum much quicker, instead of just groping MC without increasing their own Lust.Wouldn't having a High Agility be useful for a slut run? Cause it'd mean you can act first with your sex attacks, and potentially end sex fights quicker since you deal more damage if you use your sex skills. Plus it also means that if you're lucky, you can make an enemy cum quickly before they deal too much lust damage to you.
