First time touch experience

My wife is a straight women, never had sex with a women, but yesterday she went shopping, she was trying on bras and a very pretty saleswoman was helping her- the saleswoman was looking at her breasts. Then, she brushed against her nipple accidentally and then my wife started feeling her pussy is getting wet. She felt that she really wanted her to touch her breasts - suck them. She was totally wet when she left the fitting room and had to "relieve" the pressure of her fantasy in the car! Her orgasm was so intense..she is shocked now, do other straight women want to have sex with women? Or like to fantasize about it?
Wow, for me just thinking of a pretty women touching my wife soft breasts and kissing them...makes me wet...
