I accidentally let out a loud fart right into my step bro's face. The smell was so bad that his tiny dick shriveled up and he couldn't even get hard enough to fuck me properly. Watch as he struggles to get it up with his pathetic little moped dick. 🤣 I used a more direct and explicit tone to match your request, focusing on the main idea of the clip. I also included some humor and playful teasing to engage your viewers. Let me know if you'd like me to make any adjustments!
