Your sister

Thank god I have long strides because this girl was quick. But not quick enough. But I couldn't just grab her, so I ended up tackling her. Now, I was nice enough to twist my body under them so that they landed on me rather than me landing on them. Rolling her over, and moving to straddle her, I realized just who I had caught.

The face and beautiful eyes staring up at me was that of my younger sister. "Oh come on. Don't you think this is a little far? And a little weird?" she asked rolling her eyes. "Why are you trying to strip us? It is really kind of creepy."

"Well, I saw Isabella naked and it gave me an idea. Besides, I have always wanted to see these girls naked anyway. Now I have an opportunity."

"Yeah but....Wait, you're not going to strip me are you? That would be so disgusting." she said screwing up her face in disgust.

"Well, I can't very well give my sister preferential treatment. Besides, you might be happy that it is me rather than Hunter. I have a feeling he would be really handsy with you. I am pretty sure he wants to fuck your brains out."

"That is so gross." she said.

"I know. So see, you are better off with me."

"I would be better off staying in my suit and you getting off of me."

"No, I don't think I am going to get up until you are naked. Sorry." I said, shifting so that my knees kept her arms trapped. Leaning forward, I pulled the straps of her suit off her shoulders and down her arms. Then I realized I had made a mistake. I couldn't get the straps past my knees without letting her arms go. Oh well. So I moved my hands to her suit at the top of her chest. Wrapping a hand around the fabric on either side of the middle, I started to pull but was knocked off balance. I fell over and my sister took the advantage. She rolled over on top of me and crushed my boner between us. Sitting up, she looked down at me.

"Really? You're hard right now? Over stripping your little sister? That is so weird you stupid perv."

"Says, the one who is still sitting on it and rubbing it. Let alone the fact that you are mentioning it."

"I am NOT rubbing it." she protested, apparently furious at the notion.

"Sis, I can feel you moving back and forth."

"Well, if we have to be naked, then why don't we get to see this?" She said blatantly ignoring the fact that I had just caught her grinding on my dick. Scooting back she yanked my suit down exposing my dick and allowing it to pop free and point straight up at her. A look of shock crossed her face in the split second it took for me to take advantage of the situation and roll her back under me. Then she broke out of her trance enough to whisper, "You have been packing that this whole time?"

"Well yeah. You could've seen it before if you had asked."

"I wish I would have." Taking my chance I slipped her suit past her tits while she was too stunned to resist. Pausing with it at her waist, I looked at her tits.

"Wow sis. Those are fantastic. I wish I could have seen them earlier myself." Then I continued the removal of her suit. I tossed the now empty fabric over with the other suit and then turned back to my sister.
