He was not worried about being seen as he was on the twenty fifth floor. He sat her on the table there and spread her legs and shoved his hard cock in...her and as he fucked her out there he sucked on a big hard nipple. Then he stood her up and put her hands on the railing and bent her over just enough to get his cock back in her and fucked her as he played with her tits. He loved the idea of being naked and fucking her out there. He did not even care if any one could see them but he knew no one. I said stay right here fast walked thru to the bathroom sat the toilet lid down and sat on the toilet I looked in the hole and stuck my hand in and said "give me your cock" I could see his eyes get big and light up and a big smirk on his face as his hands hurried to his zipper he was fumbling to pull his cock out in a hurry. He said oh my God no fucking way you made a gloryhole. I said no I fell through the wall and improvised. By the time he pulled his cock out it was already rock hard. . He forced his cock in my cunt.He fucked me hard and deep. Then he rammed his cock in my ass with no other lube than the pussy juice on his cock. He grabbed my tits and forced his nails into them while he pulled my body towards him to get his cock in even deeper. He fucked my ass and cunt for a long time and then he pulled out. He took his belt off and started beating my ass and legs. It hurted so much that I started to make too much noise. I put a roll of ducktape for him to use on the side. "She passed me the soap and a flannel, and turned her back to me.There was no option but to do as she wanted, unless I wanted a row, and Dad coming in to find us both naked in the shower together...I moved over a little, so that she could get her back under the flow of water, and then I applied the flannel to the bare skin that I had admired when I had seen it lying on top of Adrian a few days earlier.My kid sister did indeed have a lovely back, and I had to resist a strong temptation to soap.
