SB 8.12.26
sa tam ayantam alokya
vivastra vridita bhrsam
niliyamana vrksesu
hasanti nanvatisthata
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The beautiful woman was already naked, and when She saw Lord Siva coming toward Her, She became extremely bashful. Thus She kept smiling, but She hid Herself among the trees and did not stand in one place.
