Roy.As I was reading, I felt a tickle between my legs. It turned out that Tia had crawled between me and the sink, and was trying to lick my balls.It ...as time to put Mr. Paxton's advice into action. "Stop that!" I snapped. "While I am working, or reading, you are not to touch my person!"Tia hopped back, like I had hit her with a cattle prod. Both dropped to their knees. "Yes, Sir. Sorry, Sir," they said as one.I turned back to my computer. There was an e-mail from both my dad and my sister.. Unfortunately that part never happened. She did send me a sexy, lacy pair of black boyshorts though with a very nice creamy stain right in the crotch. I was alone, and my heart was racing a bit as I opened them. They smelled so nice that within 2 minutes I had 3 fingers inside my pussy and her panties pressed firmly to my nose. I came almost immediately, but it was too quick. It wasn’t nearly enough. I opened up some pictures that she had sent me of herself in, and out of the panties, and I. She proceeded to lie over my lap while I was sitting on my chair. I caressed her back from her neck till her ass hole. She knew what was coming but obeyed her master. I then slowly caressed her right ass cheek while pulling her hair with the other hand. “Aaaah….” She screamed as I pulled her hair and before she knew it, I gave a tight slap across her ass. “Aaaaahhhh” she screamed louder. Her ass giggled like two water balloons. Her boobs were dangling down from my lap and they too swayed like. Before long I felt his hand reach up and feel my tit. Unconsciously I shifted my body to give him a better angle to play with it. Are you close to cumming yet? I asked him. He just shakes his head back and forth in an emphatic no. Not wanting him to hurt from not cumming I decided to take the next step. With my tit still in his hand I leaned forward and took his cock into my mouth. I knew I crossed a line but I figured that line had been crossed a long time ago. My son groaned as I took him in.
