I've become frustrated by how quickly you cum. As soon as you see my perfect tits you lose control and blow your load. I'm going to train you to last this time. Wearing a sexy blouse and skin-tight pants, I slowly tease you with my clothed body, giving you peaks of cleavage and glimpses of my thong but not much more as I instruct you on when and how to stroke - and when to stop! As your desperation builds you wonder whether or not I'll really let you cum. Sure - if I feel like it.
