New Little Sister

... of his junk, my step-mom liked that, but didn’t like seeing mine.

So, this past weekend, we had all gone to the beach, me, dad, step-mom and little sister, along with my step-mom’s sister and her family. We stayed all day Sunday, me and all the kids played in the waves for hours, had a blast. My little sister had on this terrific bikini, had one of those bandeau tops, no strings around her neck to hold it up, and a tiny bottom with strings on the sides, holding it together. Her cousin got great fun out of reaching out and dragging her top down, so her tits popped out, she would blush and pull the top back up and slap at him as he laughed and swam away. Then he got the brilliant idea to pull the strings on the bottom, and it fell down her legs, right in front of all the family. Well, that got him in big trouble, he got bitched out and grounded, no more playing in the waves the rest of the day, but I got to see my new little sister’s bare pussy for a few seconds.

We got home late, and I claimed first dibs on the shower, got cleaned up and just put my cut-off shorts on and sat on the couch watching TV, a short while later dad came out in his favorite lounge pants and sat on the other end of the couch, told me my step-mom had a bad headache and went straight to bed. Lucy came out in her long t-shirt, and lay on the floor with her legs pointed toward the couch as we all watched TV. As she lay there, she would lift her feet up and squirm around, attracting my attention, ...

... and I could have sworn she had no panties on!

So, when the news came on Lucy got up and came over to my dad and hugged him like her normal deal, but instead of just kissing him on the cheek, she kissed him on the mouth! And, not just a quick kiss, but a long one, and looked like she had her tongue in his mouth! As I watched, I saw that the fly on dads pants was wide open, and his dick was exposed, don’t know if he realized or not, but when Lucy ended her kiss with him, she saw it, and smiled big. Then she stepped over to me, and I asked her if I was getting a nice big kiss too, and she smiled at me and straddled my legs and sat down on me and wrapped her arms around me and kissed me hard, sticking her tongue in my mouth, and we made out for a while like that. She moved up until her pussy was grinding against my hard dick. I moved my hands down to her ass, and slid them up under her shirt and found out she didn’t have any panties on! I started sliding my hands up her body, the shirt going up as I went, then Lucy raised her arms up, and I lifted the shirt clear over her head and off. She was now sitting there on me, totally naked! We went back to making out, and her hands went down to my shorts and she was pulling the waste band down, my dick popped up and she wrapped her hand around it. I lifted us both up and pushed my shorts down as she lifted herself up, and I took them off completely, we were now both naked on the couch. I looked over at dad, and he was jacking his dick ...
