Incest Back Seat Sister Slip

[neerathemall]

Shayla sauntered off without another word... as Steve helped me out of the back seat and noticed my cock poking against my costume.

"You got hard from your sister sitting on you?" he asked.

I shrugged, trying to act casual, even while I felt more cum leaking out of my shaft, "What can I say?"

"You're a very sick man," Steve congratulated, and he high fived me.

"Did she really get you off?" he then asked Baker.

Baker answered not with shame, but pride, "Twice!"

"Fuck, why did I agree to drive?" Steve sighed.

"Because you don't drink," Eddie said, always getting more talkative when no girls were around.

"Still," Steve said.

"Let's go inside and find some hot ladies," I urged.

"I'd still rather carry on and go to the other party," Eddie said doggedly.

"If there's only as much as a one percent chance of my getting a hand rub from Shayla, I'm definitely staying," Steve said. "And it's my car, so end of story."

"She's my sister, you know," I reminded them.

"Yeah, yeah," Steve said, as the other two started walking towards the party. As he was closing the driver's side door, which for some reason I hadn't yet done, he asked, "Why is there a thong on the back seat?"

My eyes went wide as I shrugged, "I have no idea." Then I thought to add, "It's your car, horn dog. Don't you know who's been partying back there?"
