Not with My Twin!

Mostly, she listened, giving single syllable answers while trying to push my hand away from her pussy. When that didn't work, she gave up and started stroking my cock. "He's right here," she said. "Okay, Mom. I promise. Here he is." She handed me the phone.

Mom was never as chatty with me as she was with Robin. I listened as Mom told me grandma was fine, even though she had broke her hip. Then Mom made the big announcement. She was going to spend the summer helping grandma. As my eyes went wide, Robin slapped her hand over her mouth to muffle her giggles.

Mom made me swear I would look out for my sister. "I promise to look out for her," I said, smirking at Robin. "If she's bad, can I spank her?" That made Mom laugh and we said our good-byes.

"Mom said I wasn't allowed to have any boys over while she was gone," Robin told me.

"She told me the same thing about girls," I said. "You know what that means, right?"

"What?" Robin asked as I moved back to the floor. I pushed her legs part. The couch was just the right height for what I had in mind.

"It means I'll be masturbating a lot this summer," I said, aiming my hard cock at her wet pussy.

"Me too," she sighed, wrapping her legs around me and pulling me close. When she leaned forward and kissed me, I knew this was the start of a very interesting summer.

I hope you enjoyed that little story. I did my best to proofread it and tighten it up. I'm my opinion that a good sex story should get to the sex as soon as possible. I certainly tried to do that. Comments and kind votes are always appreciated!
