Plot: Girls with breast complexes who want them bigger visit a bust-enhancement salon. The esthetician, excited by the young, cute client, gradually gets more handsy and under the guise of "breast-growing massage" starts touching her nipples. The girl endures at first thinking it's part of the treatment, but having such sensitive nipples, she can't help but enjoy it... The esthetician gets increasingly excited leading the girl to pleasure and keeps escalating the situation.
