From Thread 1

You drop the panties and get into bed.

"Brandon, no," the sister says. "I'm really horny, but you're my brother. We shouldn't be doing this."

You grab her skimpy panties and rip them off of her.

Do you:

• Stick your prick in the sister's pussy
• Stick your prick in the sister's ass

You are possessing:
