Rubbing Off in A Fitting Room

One day in the summer while my friend and one of her friends were out shopping at an upscale department store, her friend dared her to rub one out in the fitting room. She was pretty horny, so she was like “Cool! I’ll do it.” She went in the fitting room with some clothes to try on while her friend stood outside to keep an eye out for anyone coming. She pulled her shorts off, sat down on the bench and slipped one hand into her panties while the other slid up under her top to play with her breasts and hardening nipples. 

She was wet already, and got even wetter as she teased her clit between her rapidly rubbing fingers. After a few minutes of this, she came really hard, feeling her pussy gush all over her fingers as she suppressed a really loud moan. Then she got up, took off her panties and put on a spare pair from her bag, and just started trying on clothes like normal. When she left the fitting room, she gave her friend a wink and a thumbs up, then they went up front and paid for their purchases with no one the wiser.
