I grabbed her boobs and put my face in the middle and MOTORBOAT the shit outta her titties. Man. Those boobies are the best. Big black nipples. WOW. S...cked on those nipples. They were so hard and so pointy. They were staring at me. Haha! Now, my cock was ready to explode haha.She started rubbing her butt on my cock. I still had my shorts on all this while and so did she. I told her I was gonna cum soon. She removed my shorts now. We were on the couch. She put her pussy against my face and. I don't mind either way."Something in her tone made me feel really defiant. "Oh, yeah?" I ask, arching an eyebrow, and removing my hands from my crotch. Was it my imagination, or did my sister have an hungry look in her eyes?"I see Amber didn't seem to take care of that in the shower. Would you like some more help?"My jaw dropped for a moment. Was my sister propositioning me? Why wasn't I as surprised as I thought I should be? My defiance was still strong, though, so I simply answered, "I doubt. My thighs were hitting her butt cheeks each time my cock entered her asshole as she moaned in excitement..she squealed a few times while my cock rammed her asshole like a bull and squeezed her bum cheeks while fucking her asshole!!. I started to finger the other girl's asshole while fucking the girl bent over in front of me. I took one of the girl's panties from the bed and sniffed it....whoooaahhh!!!..it smelled of perfume and some must around the pussy area and smelled fresh the area that. Check.Instant surrender is never a good thing, so whilst she thought forreasonable excuses to mitigate the requests, she actually thought about itfor herself for once. Caroline and Zoe out of the house. Check. Saturdayso no school. Check. Katie at home with just her. Check. Fiona requestingto see Katie. Check.Hmmm. Maybe she could surrender in such a way as tonot lose face in front of the enemy. Tricia would apportion blame entirelyonto Katie for what happened next as at precise that moment.
