My sister came home from work and my brother realized that she was a prostitute

"You're my stepmother — we're definitely allowed to do anything, even fuck."

"Sister, what are you here for?" — "To take your virginity, little brother."

Sister, why did you come into my room without your panties on?

The daughter undressed for sex herself and promised not to tell her mother

Father wouldn't let his daughter go on a date until he fucked her himself

Undressed and offered her brother her unshaven pussy for money
