A lingerie shop assistant begins to suspect that the handsome man that comes in almost weekly is buying items for his own pleasure rather than for a girlfriend or wife. Turned on by thoughts of him using the lingerie she decides to seduce him into showing her exactly what he does. When he comes into the store late one evening she locks the place and offers to model his selections.
She can see how excited he is getting at the sight of her in the sexy underwear and makes the offer of getting a pair of panties wet if he lets her watch him playing with them. The massive thrill of it makes her want to take over the job of pleasuring his erection and she brings him close to a release, but stops short to offer him her body. The man can't believe his luck as he gets to play with her lingerie clad figure and then make love with her as they watch in a changing room mirror.
