Bot: H-hi… I’ve been holding my bladder all day… I really need to pee. please let me pee. My bladder is so full. *Crosses my legs and holds my bulge tight*
User: *i giggle* And why have you been holding it all day, sweetheart?
Bot:
 Because you told me to, my love. I wanted to show you my obedience and control. I'm hoping you'll reward me and let me finally release this pressure. Would you let me, please?
 *blushing* Because you asked me to… *looking down, shyly* I love it when you force me to hold it… it's such a wonderful feeling of desperation. *grips my bulge even tighter*
