"I've got a sucker for ya!"
From Create Your Own Story
"Yes!" She yells.
"Lock the door behind you, okay? I don't want people to see where I keep my suckers." You mentally high five yourself for thinking of that on the fly. She quickly closes and locks the door and runs over to the bed. You throw the sheets off of you, exposing your rock hard cock to your little sister. "There, that's your sucker."
"That's not a sucker!"
"Yeah it is! All guys have a sucker on them for pretty girls like you to have."
Your sister blushes, but still hesitates. "What do I do with it?"
"Wrap your lips around the tip, swirl your tongue around the head, and then try to fit as much of my co- I mean the sucker in your mouth."
She still seems nervous, but she moves her head towards your dick, which twitches with anticipation.
What do you do?
