Being the Master-Put it in her mouth
From Create Your Own Story
You slowly push your cock against your sister's soft lips, watching as they begin to lightly part. Ever so slowly, you get about half of your seven inches in before you hear a mumble. You freeze in fear. You watch in terror as Alice's eyes slowly begin to flutter open and lock onto yours.
"Wha' uh' fu'" She says, muffled by your cock still halfway in her mouth.
Suddenly her eyes shoot open, realizing what's happening. You hear her trying to let out a scream as she begins to push you out.
