because there and erogenous zone of the body, (a sensitive area with lots of nerves:

Breasts are familiar territory for most men and they're fun, so it's unlikely you'll shortchange them. The mistake you're more likely to make is giving them too much (or too vigorous) attention before she's ready. Over-stimulating the breast can be numbing or painful for women during some parts of their menstrual cycle. Try taking the less-is-more approach. Touch her breast softly, then lift your hand away for a moment, and then continue. That allows her to have the important moment of anticipation. Stick to indirect stimulation of the nipples until they become aroused (hard) and don't just focus on the bull's-eye; same concept as before - anticipation. The entire breast is rich in nerve endings and all breasts have the same number of nerve endings. Thus, the woman with smaller breasts may experience increased sensations per touch.This results from a condensed amount of nerve endings. All breasts respond with time; lovers, go slow, take your time and slowly fondle the breast. Areas that are especially sensitive to touch include the nipple and the areola (the pinkish area that directly surrounds the nipple). One of the most sensitive spots, which is often ignored, is the underside of her breast. When kissing and touching her breasts, try starting around the outside and moving inward with slow circles. She may push your mouth or hand directly to her nipples, but don't let her do it, just continue moving slowly towards her nipple. Take your time; she is not going anywhere, so tease her. This whole process should take at least a few minutes. Next, wet the tip of your finger and lightly touch and roll her nipple around. Then, very lightly, using your fingertips, squeeze the nipple between them and when they are nice and hard, bring your mouth in. Note: some women enjoy nibbling and rougher play, while others are really sensitive and prefer light soft touching. Find out her preferences by asking or watching her reactions.
