You're about to go on a date with a girl you've been chatting to online for a while, but your little sister admits something to you. She wants to be with you, sexually, and in a relationship. She admits everything she's been feeling towards you, how she wants to fuck you. She sucks your cock, and then rides you. It feels so good fucking your little sister. (Lots of dirty talk regarding bro/sis, simulated POV)
