I had no problem with that; I loved pounding myself riding a cock and knew how to do it best. My ass slapped against his thighs with a *slap, slap, sl...p* and I could hear Blake begin to moan. I knew he was enjoying it and I was in absolute heaven. I could feel Blake’s balls slap against me every time I slammed down on his cock and noticed how they kept growing and growing and his cum built up. I knew that a big reward awaited me at the end. Eventually Blake started taking control again and now. Especially when I'm so willing to make you feel good.'"Holy shit, step sis, you are amazing. I just still can't figure you out. I used to be the one obsessing over you, but now it seems like the roles are reversed. Why is that?"I calmly slid my lips off his member, but immediately took it in my right hand and stroked it for him. "Well, I was trying to figure you out too, dude. We both know you loved the sex we had, but then after two weeks, I caught you jacking off into my undergarments again.. For a moment I thought Mr. Ziminski was going to hit my dad, but with a final snarl he stormed out, almost knocking me over as he went past."Well, that was exciting," Dad said as Mr. Ziminski slammed the front door on his way out."Sorry, Dad," I said."Don't sweat it," he said. "I don't think any sane person in the world would believe you started the fight, and I'm sure once he thinks about it, Mr. Ziminski will reach the same conclusion. I'm proud of you for standing up for yourself, but not. Mom drove up shortly. She reached over and opened up the front passenger door."Let Sara sit up front."We eased her in and I handed the seatbelt over her to Mom after I'd swung her legs inside. Once we got her seated I closed her door and got in the back with Mary. I grabbed Mary's hand, squeezed it and smiled at her. She smiled back. I let go, surprised she didn't attempt to pull away.We made our way home. It was quiet for most of the drive. I think all of us knew we were going to talk about.
