Satan, oh what a joy Sunny is. Loving that soon to be slut/whore. Yes, I would love to see her making money with those milk jugs with the huge areolas. My mouth waters just looking at them. I don't know you, but, I'd bet my last dollar that those big areolas are a major fetish of yours, and now mine.
As ronan said, let's get it on with her corruption, full speed. Would love to see Sunny having to wear a super slutty outfit while working in the bar, maybe, there's even a gloryhole there. Very handsy customers who will pay her for paying them a little extra attention. When Sunny gets home she gives her hubby, sloppy 2nds, 3rds, or whatever.
A couple of optional thoughts if you don't mind and for your consideration. Maybe, they will adopt a pet dog, or Sunny can find some part-time work at a stable. How about a visit from Dad, Mom, Brother or Sister and things get a little frisky.
Loving all the NPC's that you are already working with, let's just take Sunny deeper, much deeper down that rabbit hole.
