"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."

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
