Begging stepdaddy to get out because I can't hold it and then he brings out the dirty girl in me

I can't hold it much longer stepdaddy. My belly's starting to cramp. I really need to go! I'm sorry I disappointed you and failed my exams. Please get out. This is embarrassing. Why do you punish me like this? Oh no! No NO I'm going to pee myself! Why do you make me do these dirty things? Ok fine, I'll do whatever you want. Can I pee now? HOLD IT?!?! But my bladder will explode! You want me to spread my legs? No I don't want to show you my naked pussy...but okay. There. Now can I pee?? PLEASEEEEE. Touch myself while holding it in? Okay stepdaddy. I'm sorry I let you down. I'm going to do my best to make you proud. This feels so shameful & embarrassing but it's making me horny at the same time. You bring out the dirty girl in me stepdaddy. Mmm rubbing myself in front of you as I let my pee out while feeling that warm gush all over my hand while masturbating makes me horny. I want to cum for you & get even dirtier step-daddy...
