" She husks to Hannah while pressing her thumb hard against Hannah's clit again. Hannah lets out a mix of a scream and a moan. Her body arches and her...muscles squeeze Katherine's still thrusting fingers. Her knuckles turn white as she holds onto the ropes with a death grip. She let's out gasping whimpers as she comes down from her climax. Katherine breaks her dominant role to pepper Hannah's neck and shoulders with light kisses. Hannah sighs and Katherine pulls out of her before setting her. My dick was throbbing now and pointing straight up "your cock is so fat, how big is it?" she asked. I told her it was six and a half inches long and seven inches thick. Veronica said wow and told me I could do whatever I wanted to her. The first thing I thought was to grab her, bend her over the couch and just fuck her. So that's what I did, no foreplay, no kissing just straight to fucking. I turned her around and bent her over, I grabbed my throbbing cock and put it against her pussy. I began. I dry hump her as I move my hands up from her sides onto her boobs and press them and let my lips kiss her neck again. She starts grinding my cock which starts getting hard and all we can hear now is her heavy breaths with moans and me sighing on her neck as she moves her ass faster.I pushed her down to the bed and started biting her nipples hard and sometimes licking her armpits.Which let out nothing else except the sweat smell by this time she was totally under me and couldn’t move an inch. Helloooooo?" She said to him mockingly.He just froze there with his mouth half open, he couldn't believe that his sister, his little sister, would grow up to be this gorgeous, and hot..."Isaac!!!" She poked at his chest with her delicate finger.He shook his head to clear his mind and then looked at her, then gave her the warmest smile he could ever produce and then hug her tightly."Oh... my God... look at you... my little sister has become such a gorgeous babe... I just can't believe it... I.
