You turn to me and say i want to ride your cock. i sit down and you open you pussy lips and i push my dick in you pussy, you start to ride harder and ...harder i can feel the juices running down my cock. The more turned on you get the dirtier you become, you begin to slap my face as you start to climax and i grab and squeeze you ass sliding a finger in your ass.The main toilet door opens and we still keep fucking hard as ever, They hear us fucking as we can hear them giggling, i hear a voice say. She was moaning like fuck me pls fuck me, don’t stop and finally she got her orgasm and I came after 15 min. After some time I started kissing her and sucked her boobs. I even bit it a couple of times. I also kissed her neck, licked her navel. . She said she can’t take it any longer and told me to insert my cock.She sucked my cock for some time and it became hard again for the next round. I finger fucked her for few min and then put some baseline in my cock and pushed my cock inside. It was. “No, she just wanted to watch me cum.”“You’re not still a virgin are you?” she abruptly asks. The question throws Chance off for a second. His face reddens again, this time a deeper shade of the color. Seeing his discomfort, she quickly adds. “Don’t worry, little brother, it’ll happen. You’re hot. I mean, for other girls. If I wasn’t your sister I’d fuck you.”This statement brings a smile to his face, and it’s one he can’t control or stop. “So, uh, when are we heading out?”Rory grins. “Finish. "So you don't think we're perverts?" Like I said, it's not my role to judge things like that," I said, marshaling my thoughts as the psychologist in me struggled to take charge of my brain again. "I've seen a lot of strange relationships." I was immediately sorry I'd used the word 'strange', and changed it in my next breath. "Different, I mean... unusual"."Oh, believe me, we know just how... unusual... we are," said Kathy.It suddenly occurred to me that they had told me a deep, dark secret.
