Brittney comes calling.

Your cock finally starts to shrink and you realize that you are very tired. You turn off the TV and head off to bed. As you pass your mom's room you see that her light is off, she must have gone to bed. You wonder if she wants you to come into her room and fuck her, but then you deicide to hold off on that and head off to bed. Somehow with all the thoughts filling your head you fall right to sleep.

Morning comes swiftly and you wake up with a boner as usual. You are just sifting through your collection of porno tapes to find a good one to jack off to when you hear a soft knock at your door. You answer in an irritated voice, "Yeah, what do you want, I'm trying to sleep."

"It's me Brittney. I want to talk with you."

You groan in frustration and head over and unlock the door. "All right, but make it quick. I need my sleep."

"Yeah, I'm sorry but I need your help." She stops for a moment and catches her breath before starting to talk again and then her words just seemed to spill out, "This is really hard but I am just going to say it, I need your help to learn how to have sex. I have only done it a couple of times and I don't think I am very good. I want to practice on you. I really like Kevin and I want to make sure I please him."

You look at your pretty, sexy sister and wonder if you are still dreaming. She is wearing a thin white t-shirt and you can see her pink nipples on her small taut breasts. You look at her shapely legs and tight ass, and wonder what you did right to deserve this. She stares at you for a moment longer and you realize that she is waiting for you to say something. You answer her trying to keep a casual tone in your voice, "Of course I would be glad to help you. How would you like to start?"
