MNGS-084 - My girlfriend's sister is a total slut and she's begging for it...

My girlfriend's sister is a total slutty gal and she's way too hot! When I went to stay over at my cute girlfriend's place, I was met by her gal sister who kept getting way too close and seducing me! She kept whispering that her sister wouldn't do these things, leading to intense sex in the bath, right next to my sleeping girlfriend, and morning blowjobs! Her techniques are insane and she keeps begging for more even after 20 rounds!
