My Sister’s Hands PT2_(0)

Marilyn stroking my cock was the best thing I ever felt. I couldn’t wait for the next time we had the house to ourselves.
Well, I didn’t have to wait very long. Two days later our parents announced that they were going to a business meeting Dad had on the west coast and that Marilyn and I would be staying home. Oh darn…
I had just gotten my driver’s license so it was my job to take Mom and Dad to the airport.
“Take care of your sister,” Dad said, ” and no parties!”
A little voice in my head said, “No problem!”
When I got home Marilyn was out laying in a chaise by the pool. She was wearing a thong bikini that covered her private parts, but just barely. The top was two little patches of cloth that hid only her nipples. The bottom was even smaller.
“Where did you get that,” I asked? I couldn’t take my eyes off of her.
She pulled her sunglasses down just far enough to look over the top of them. “I bought it a few weeks ago. Been hiding it from Mom and Dad. Do you like it?”
Before I could answer she looked at my crotch and smiled. “I think you do.”
There was no denying that I liked it. My dick was already solid.
“So, what have you got planned for today?” I said matter of factly.
Marilyn shrugged. “I don’t know. I thought about going to the mall with Becky or maybe a movie with Sally.”
My heart sank.
