” I said. That’s when I hears my cell phone vibrate. It was from my sister she said for me and Johnny to get ready because she was coming to pick ...us up in 10 minutes. We both instantly got boners. We threw on our shoes and waited outside for my sister, when she picked us up she smiled at us very devilishly and we drove off. Johnny asked where we were going and she said to the corner store and then the motel room that Jessica had picked out. When we got to the store we all got out off the car. I didn't have anything important that I had to do, but I didn't think she really wanted help with math. I was sure she had something else on her mind that had to be done before our parents got home. Finally I put my laptop to sleep and went to Julie's room. When I opened the door, she was lying on her bed butt naked with her legs spread in invitation.Before she had a chance to speak, I said, "Jules, it doesn't look like you are ready to work on math problems. Maybe I'd better come back later. ”“Don’t be shy Grandpa – I’m sure you have a very nice cock, I know Daddy has, but I can’t ask him because he thinks I’m still a virgin”Amy did a little shimmy, rolling her hips to some imagined music and sticking out her chest. She caught my gaze and slowly removed the tiny bikini top, revealing her very attractive developing nubbins. Behind her hands the nipples were dark and pointed on top of succulent little tits – she rubbed them for my pleasure – hardening along with my cock.“Please. The anticipation is driving me nuts. Not to mention that my nuts are feeling pretty lonely. What have I been missing?”Karen said, “I am pretty proud of it. Everybody, should we show him?”To keep the mystery going, Cindy said, “I don’t know. After all, you are Dave’s vacation wife. Would that be cheating?”“I can handle it,” I said.Karen stood up and reached to untie her grass skirt. Then said, “No, I can’t. Cindy, you should go first.”“If you insist.” Cindy stood up, faced Ken, and dropped her.
