After talking on the phone about your embarrassing incident I invite you into my office to discuss. I go over the details to make sure I understand, you woke up desperate to go to the toilet but your bathroom door was stuck, the effort it took to release it made you soil your white boxers, you finished releasing on the toilet, but were so turned by it all you sat there and jerked off as well. As I'm talking you need to use the bathroom, but it's locked, I pretend to not know anything about it and ask to carry on.. you get more desperate through our session.. and I confess, I put laxative in the tea you've just had, and have locked the bathroom door. Hearing your story on the phone turned me on so much, I wanted to see it in real life. You strip off down to your boxers and begin soiling yourself, we both masturbate before we carry on with the session.
