No, you don't understand. There are no limits to breasts.
Once, the devas were arguing whether a cute girl's breasts were really impossible to escape from, and Vishnu and Brahma, complacent in their power, said that they would conquer breasts like they conquered so many asuras and spirits. They summoned their wives at once, and Vishnu dove down Lakshmi's cleavage at the rate of 84,000 crores of yojanas a second for 84,000 crores of mahakalpas, while Brahma flew up Saraswati's underbreast at the rate of 84,000 crores of yojanas a second for 84,000 crores of mahakalpas. Neither saw any sign of reaching the other side, and fearing for their own lives, they retreated and bowed down before their wives.
