"You ready for all this ass? Can you handle all of this?" I sure as hell in my mind am going to try. Problem is, I'm so turned on by the sight of h...r twerking that ass that I u*********sly start licking my lips. I get on my knees and move my face inches away from her perfectly round ass. "Oh you LIKE that shit huh? You like my bouncing ass in your face don't you!" I'm in a trance. She leans onto the desk and reaches both hands behind her and spreads her ass as wide as she can. "You want. "Clean me up and get me ready to fuck Jessica, sugar," I ordered with coldness in my eyes. It wasn't the first time I'd taken this tone with her in the past week, and I didn't plan on it being the last.Lexi hesitated for a second, staring back at me with just a hint of a plea.

I took a half step towards the open door to conceal my now naked ass. Got that?" "Yea Dad." "Sure have fun Daddy!"We all had supper together and as soon as we finished dad left. I was still sitting at the table with Dahlia. "So hey, what did dad mean we he said no boys?" I asked. "Oh that, well it happened a few months ago, dad found me with a guy in my bed." "No way! how?" I asked again, in shock. "Well it was at night, he climbed up to my window, and I guess we were making to much noise."I was really getting turned on imagining my sister getting fucked.
