I just bought a new collar for my little stepbrother and decided to try it out. So i tied him to the furnace in the basement, and made sure to tie the collar around his neck just tight enough so he could barely breathe. His head was placed on my favorite little rocking chair. I went to go visit him after a night out, to cause a little trouble :) I pulled down my panties and placed my naked bum directly on his mouth and rocked myself back and forth. It felt incredible! His tongue moved in and out in perfect motion causing the most amazing feeling. I could still hear him breathing though, so I made sure to pull on the collar to decrease his airway. I could feel him squirm a little bit underneath me, but I loved it so kept on going. Mmmmmm.
