Head to the motel

You head to the motel, knowing that Ellie should be coming any minute now. You wave at the guy you figure is Miles, a dorky-looking high school senior, you think. His pimples give him away.

You open the door of your room.

Ellie is lying naked on your king-sized bed. "I got Miles to give me a key. I hope you don't mind."

"Oh, not at all, are you kidding?" You watch as she liquidly rises from the bed and walks to you. Her hips and tits sway in all the right ways.

"Hi, I'm John. You must be Ellie," you extend your hand as she nears.

"How did you get my name?" she asks curiously.

"The waitress at the cafe mentioned that the redhead that works at the bar is Ellie. I met her in the cafe." You leave out the part about going later for a 'sleepover'.

"That would be my sister, Connie. Well, now that introductions have been made ..." she says as she puts her arms around you and kisses you. Her lips are smooth and very soft, and her tongue gently presses into your mouth. You close your eyes and just enjoy the feeling of your tongues entwining. You wrap your arms around her, caressing her wonderful skin. Your cock gets hard and pushes into Ellie's belly.
