"Come over tonight! My parents are having dinner and I'll leave the door unlocked. Say... 8?"
Your date can't come fast enough so you head over a little early. Her parents must already be out as all the lights are off except for a glow coming from her room. The door is unlocked so you call out to her as you head up the stairs.
You step inside and there she is listening to music on a beanbag wearing almost nothing. She smiles. "You're early. I'm not even ready!" and with that hooks her thumb into her panties.
