Make the sister wear the cum-soaked panties

From Create Your Own Story

You hand them to your sister. "Put them on."

"What?"

"I want to see you wearing my cum." You lick your lips. She flushes a deep red.

"Wow. You're a lot kinkier than I thought, lil' bro..." The skimpy panties are quickly slipped off. For a moment you can see her soaked slit perfectly. Then she slips her soaked panties up to her crotch, pulling them on tight. They make a soft squishing noise, and a little dribble of your seed runs from the fabric down the side of her leg. She shakes a little, and you could swear it looks like she just came. "So, you like that?"

"Yeah." You start to stroke your cock again. It's already rock-hard... and somehow, it seems a little bigger than before. Probably just your imagination.

Do you:

• Stab your penis into the sister's pussy
• Stab your penis into the sister's ass
• Stab your penis into the sister's mouth
