I accidentally saw my friend's cute girlfriend's ass right in front of me! Unable to contain my excitement at the sight of her tight-fitting panties, I stole a glance from my friend and tied her up on all fours! After thoroughly fondling and rubbing her ass, which was stuck out, I inserted a thick vibrator into her pussy, which had become wet from the touching of her ass, and stirred it deep into her vagina! She screamed and refused, but when I pulled out the vibrator all at once, she squirted a huge amount of cum and trembled in agony... This is the second installment.
