I kind of like the pose, but I don't really have anything to ask... but since you mentioned keywords open book and dirty secrets, I'll be straightforward;
1) Tell us what is the dirtiest secret you have? Preferably something to do with... sexuality related topics.
2) You are changing something sexier clothing on in a bathroom and there is a guy (or a girl, whichever you prefer) is sitting on your bed and waiting for you. You pick some clothing and you seek out bunch of toys available from your drawer;
a) You have a blue silky nightdress, a black latex suit, a partially transparent purple nightdress, a white dress and a dense dark colored dress in your wardrobe
b) There are also multiple pieces of matching panties and bras in different colors (red, white, black, teal, purple & green); fuzzy edged ones, normal ones, silky ones, glamorous ones and a beach bikini.
c) There is a blindfold, a tickler, a dildo, a buttplug, a whip and a honey bottle in the drawer (vibrators are out of batteries and cannot be used).
Which ones of them would you see the most important to pick with you and how would you start the night?
3) During that night person all out of suddenly started to eat your ass, what will you do?
a) Let him/her munch away, while touching yourself
b) Gently lead him/her into your pussy wherever you prefer (trying to not to kill the mood).
c) Push him/her away, telling how butt is dirty (ask for a break or do whatever is necessary to change into some more standard position).
d) Grab his/her and pull that face tighter in your butt.
e) Fart.
f) Hint him/her of more real anal sex incoming once he/she get that tongue out from your butt.
g) Do something else (give a short explanation).
