Today you said you wanted to challenge yourself in your ass worship skills, so I have you come over and worship. It starts as usual, but I have an idea for testing your lungs. I do some light play, squishing out the air from you as you worship my ass. I let you take some breaths in between trials, but my ultimate goal is to push your limits like you asked for. You trust me and know that even if you're out for a while, I'll take care of you, so despite your body's natural squirming, you keep testing your breathing. You do eventually KO, but of course I wake you up with some sweet kisses and allow you to take a break and rest for a bit. Don't worry, later we will be going for longer and doing more...
