Cum in your own mouth for me

I want you to jerk off for me, I want you to follow my jerk off instructions, but they're not going to be easy. Today we're going to do a little challenge, today I want to make you work for it, I want to see just how bendy you are, but I don't want you to injure yourself so you should roll out your yoga matt and get started on a warm up, chop chop I hope you're not so unfit you can't even manage the warm up!
