Confront them

"Excuse me young ladies!" you bark as you turn and confront the two teens. "Would you care to repeat that to my face?"

The blonde looks embarrassed but the brunette looks at you with defiant scorn, her mouth twisted into a mean smile.

"What?" she sneers. "You want to get a better look at our tits Drunky? C'mon Sondra lets give the old perv a show!" She cups her breasts, pushing them up in her tight top, then reaching out and wrapping one arm around the blonde's neck, kissing her cheek and moaning in a parody of eroticism.

The blonde pushes her away angrily. "Stop it Val! I don't want to play your stupid games anymore!" She looks at you with a grimace of apology, then glares at her companion.

"Yeah Val, why don't you knock that shit off?" another voice says, making you look up and both girls spin around to see who spoke.
