From Create Your Own Story

She looks up and sees you looking at her, so she smiles and stands up, walking into the room while you stroke your dick.

"Good morning Josh! What ever are you doing?" She asks coyly, walking over to sit with you with a cheerful spring in her step allowing you a good look at your admittedly sexy younger sister. She's dressed in an old nightgown that she's worn since she was 12, except back then it often seemed too big to fit but now it seems almost too short, especially with her nice C-cup breasts pulling up the front of it and her firm round ass half visible in the back. You can't help but notice her black lacy panties and her nipples poking through her shirt as bounces toward you. You also notice how she cut a fairly deep V in her night shirt, exposing a generous amount of cleavage.

She sits down right next to you on the bed, wrapping one of her arms around you and pulling herself close you. She's curiously looking at you stroking yourself and glancing at the porn video playing on your laptop.

What do you do?

• "Well, I was jacking off but now that you're here you can suck it for me.
• "Um, just playing with myself. Guys do that when get get older. No big deal."
• You shrug, your erection fading as your baby sister gets close to you. "Nothing much, about to take a shower."
• "I was just having some fun"

Josh, age 18
