Your best friend called you over to hang out but when you arrived he suddenly had an urgent deadline he needed to work on and isn't going to be available for a couple hours. After making the trip you decide you might as well stay and wait until he's free, maybe even have a few and stay over. But right now you're stuck twiddling your thumbs, sitting with his girlfriend while she plays on her phone. She doesn't seem very chatty so you're content to just chill out but out of the corner of your eye you notice her glancing at you every so often. When you turn to face her she puts down the phone and, keeping an eye on her busy boyfriend, she starts to lift up her skirt. Raising a finger to her lips she hints you can see more if you stay quiet. You can't believe she's being such an exhibisionist right now and whilst you feel like you should speak up and tell your buddy what she's doing you also want to see whats under that cream coloured g string too. She slips it to the side and spreads her damp pussy lips for you, her eyes twinkling as she revels in her exhibitionism! Carrying on her brazen display she starts to rub and circle her hard little clit, letting the smallest moans escape inbetween her halted breaths. She almost gets caught at one point, hearing her partner shifting in his chair she just about has time to cover herself, but she's hardly deterred and when he turns around again she simply gets back to playing with her horny cunt. Maintaining eye contact with you she brings herself to a nearly-silent orgasm, licking her pussy-slick fingers before quietly going back to texting, shooting you a sneaky smile ;)
