I sigh. Then turn to see my sister completely frozen. I flinch at the site, & I push myself off the floor & onto my knees, looking at my sis. I beg...n to shake her.Cheza!!! I scream.She looks up at me w/a smile on her face.Let’s do that more often she said, she hugs me & gives me a kiss. I’m so shaken, but just laugh, as I thank God she’s OK. You had me worried sick, Cheza!! I cry.I’m sorry Reuben, will you forgive me? She saysOf course, how could I not forgive my sister. I’m just so. She was waiting until he was really moaning and thrusting and then did the one thing that Debra had said her boyfriend loved; she cupped her brother’s balls and gently squeezed them.

She pulled his cock out of her mouth and the next shots hit her chin, then her breasts and finally onto her lap. Ian didn’t think he would ever stop. "Lift up my shirt, daddy, over my belly button." I started walking him through it. He hesitated, then took the bottom of my dress and pulled up slowly, his fingers grazing across my panties, until the dress was up at least three inches over my bellybutton. My panties were showing, my tan legs, my bellybutton. I was soaked. I knew he could tell. I glanced down and saw his erection. I giggled. He turned around and got the tequila bottle and poured some on my belly button. (I know, lame body shot,. Melinda picked out a black bra which pushed her near-perfect pale melons up even higher into the dip in her top. Finally, she added a pair of black thongs with a thin lace front. I could see her smoothly shaved slit through them. The shopping made me so I hot I got Melinda to suck my cock as I drove home. I cheered her on the whole drive home, telling her to imagine she was sucking a nice, strange black cock. I came into her mouth as we pulled into our drive way. Finally, late Saturday.
