"Wow you are good at this,slave.They are so smooth now"Rachael said as she touched her underarms."Do my legs now" Rachael said and with that she remov...d the towel that had covered her body.I was dumbfounded to see my sis just in her panties and her boobs naked in front of my eyes.Rachael had really nice boobs,they refused to sag even without the support of a bra.She had small pink nipples which were tempting me to suck them hard,"like what you see?" Rachael inquired and i was awaken from my. I'd wondered about it for years off and on. It wasn't that I wanted to be attacked down some dark ally on my way home. That didn't hold any excitement for me. It was the idea that a situation could be totally beyond my control that turned me on. I was used to being in control sexually and was perhaps even a little predatory at times. I was a born flirt and liked nothing better than someone who would flirt back. I also didn't like to be outdone. If that meant some teasing - possibly a little. I wanted to touch them. My hand started moving towards them like magnets were involved. But then I caught myself. I just wanted my shirt back. If I started perving on my sister I'd wind up in jail or the hospital or worse.Sharon was shrieking like I was murdering her. She got her arms free, and slammed them across against her chest, like she was shutting a lock. I pulled my shirt back into my possession."For god's sake, Sharon, they're just tits; half the world has 'em. And believe me," I lied,. I look down to her pussy and see his thumb is softly rubbing over top of it through her suit. Then I realize everyone has stopped playing cards and was watching Vince sexually touching my daughter.

She moves her bottom against his leg again and thats when we see a wet spot of her pussy. Vance kisses her neck and at the same time.
