Dildo Roleplay in bed

What are some things you say in bed to really get your gf or wife going? We recently bought a new toy thats WAY bigger than me (9x2.4) and been role playing with it. I would say stuff like "Does it feel like youre riding on a real cock" or "Do you want to cum on a cock this big?" and even had her rate how good it felt.

What else do you guys say to get her really excited? Would love to hear your guys experience.
 
Lots of roleplay and experience also play around with qos temp tattoos but been promised she will get a real one in vegas in March has a series of BBC dildos each one bigger than the last.
