If you have mastered jerking off in 60 seconds, this is the next step in your training to become the ultimate premature ejaculator. When I start My stop-watch, you can start rubbing your cock and you have 30 seconds to cum. Since I am a kind Mistress, I will help you achieve this, by showing you My curvy body. I will even lift My short skirt a little, so that you can see My voluptuous ass, and that there's nothing under My pantyhose. If you manage to cum in the given time, then you are already a premature ejaculator, and you deserve to have a full pleasure orgasm. If not, you should keep rubbing your cock after the time is out until you are close to an orgasm, and then ruin it. Don't worry, I will teach you how to do it the right way. Repeat the procedure until you are able to cum in 30 seconds, like a real premature ejaculator. When you manage to do that, you can send Me a video of it.MASTURBATION INSTRUCTION, JERK OFF INSTRUCTION, MASTURBATION ENCOURAGEMENT, FEMALE DOMINATION, PANTYHOSE
