Unlike other molestation scenes, in that scene you have a sort of timer. Your agility determines your max time. The more stuff you do to either woman, the closer Samarra gets to waking. I wouldn't bother with going to the tent until you have max agility -- you'll get caught almost immediately.
Even at the game's current max agility of 4, you don't really have a lot of time before she wakes and you're caught. Basically, you can more or less fully peep one woman and that's it for the night. It's not like there's a lot to do most nights, though, so just go back another night and peep the other. <shrug>
Getting caught once is okay -- dialogue indicates Samarra likes it. Getting caught multiple times just makes you a loser, though, so don't do that.
In reality, the stuff beyond the basics haven't been implemented yet, just like the Prim and Evelyn scenes. You'll need to wait for further updates to both the scene and agility training for more content.
