Pretty simple prompt. Want a DB who can't afford an item at a store for whatever reason, shopkeeper decides he wants payment another way.

Any male shop keeper will do. Lucan, Ulfberth and Belethor are favorites though.

Squicks include toilet related kinks. Oral, orgasm denial and teasing are nice. Bonus points if another person walks in attempting to buy something while the shopkeeper is receiving oral and is desperately trying to keep a straight face as the person browses.
