You want to be able to cum? I guess I can accommodate this base desire of yours. But you're going to have to follow my instructions. You're going to have to sit on your hands and leave your cock alone as I tease you mercilessly. As I writhe and move in my skin tight white dress you're going to have to abandon your cock and be patient. You can see I'm not wearing any panties under this dress. Do you think you can abstain from stroking with that in mind? When I give the command you'll have one minute to cum. If you can't get the job done in that one minute, then you're just not going to get to cum at all.
