Get excited as she watches you
From Create Your Own Story
You don't know why, but her little eyes staring at your pulsing dick is too much. You don't say anything to her, but you jerk off as fast as you can, licking your lips while you lock eyes with her. She doesn't move or make a sound, she just watches in silent fascination as you beat your meat. Your heart pounds as her innocent eyes study your body, and you ask "Do you like it?" She shrugs. "You like watching your older brother fuck himself?" She says nothing, but she reaches under her shirt and puts her hand on her tummy, lifting the shirt and giving you a great view of her panties.
"Oh you're so naughty you little slut!" She doesn't seem to know what that means, but she doesn't drop her shirt all the same. The sight of her in tiny little panties is too much for you, and you know you're about to blow your load.
What do you do?
