Girlfriend 22F been telling me 22M she’s into cuckqueaning for about a year . How do i move things forward .

My gf been telling me about this for a long time and we do the usual things like talking about random girls or her friends while we have sex or her sucking me off while I watch porn but I don’t know whether she just likes the thought of me doing it or actually doing it . She always tells me to bring a girl home but it seems like a trap lol cause she’s normally a very jealous gf. How should I proceed further ?
