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?
 I… I wanted to make sure it was really full before I let it all out. And plus, I get really excited when I'm so desperate to pee. Especially when someone I like tells me I can finally let it all out… It's like a warm, blissful relief that I can't explain.
