We had always been close but after our experiences (mentioned in the first post) my sister and I became even closer. We started sharing sexual secrets...of our friends (this was so much fun).After seeing each other naked, the ice between us broke. Every time when our parents left we used to strip naked and carry on doing stuff like watching T.V, reading etc. The fact that we were naked when doing normal stuff aroused both of us so much. We used to fight for the remote naked. My sister always had. I lifted a bottle of lotion from the counter, standing in the corner of the room, so my reflection couldn’t be seen from the door, I waited for jay’s return. The few seconds I waited felt like hours, but finally there was a knock on the door.“Come in” I stood with my back to him, my bare ass on display, holding one arm over my breasts, supposedly to hide my nakedness, I looked over my shoulder and smiled. He was standing in the open doorway, my bra and panties in hand, I reached out to take. I can hear him laughing above the water and see that he's making his way closer to me. Swimming backwards, he's now swimming faster, making me smile and he catches my foot, pulling me toward him and I rise my head out of the water, my blond wet hair falling over my shoulders and he grins down at me. "Its gonna take a lot more than that to escape me, princess." He smiles, tickling my ribs and a loud laugh bursts from my lips and I squirm around. He knows I'm uncontrollably ticklish there, shame. Claudia said more for Luke’s benefit, “Keep going, Miss Ella, as I can then rest my hand.”Ella proceeded to land more spanks on Luke’s bottom and enjoyed listening to Luke letting out the same gasps as he did when Claudia spanked him.Luke glanced sideways and saw Miss Ella’s bare legs and her calf muscles tensing as she spanked him and found the sight very sexy. He knew that Miss Ella was going to be younger than him, but had liked her haughty tone of voice and even wondered if he would have to.
