You like the way my breasts dangle? Hehehe. Okay, very slowly, start stroking up and down as best you can. Feel the material against your frustrated cock. Stare at my breasts while you stroke for at least 2 minutes, but again, you can go longer if you want to.
Oh by the way, did I mention that you can't cum? I didn't? Oh how silly of me...all this talk about rubbing and staring and stroking...
You didn't cum yet did you? Well, if you managed to cum, then you must quit and not look at any teases or porn for the rest of the day.
If you were good, then you may keep stroking for at least another minute, and rub your balls with your other hand.
