We're old friends and I stop by unannounced to make small talk, but you can tell that I'm antsy and uncomfortable - then I ask to use your bathroom. You decide to peek in on me and once I notice you, I beg you to leave so I can potty. Finally, I've made enough excuses and I tell you the truth- I'm not a secretary, I'm a professional cumdump. I sit at my desk all day and guys line up to come use my butthole. I'm so full of cum, I stopped by your house to release it out of me. When you won't leave me alone in the bathroom, I finally realize that you want some too and that makes me horny so I dirty talk you all the way through fucking my ass and cumming in it. Your cum squirts out of my ass after you pull out and I sit on the toilet and release all the cum out while you watch.
