Gf turned into size queen. Give me some more ideas or question to ask her

I (28) told about my small penis humiliation fetish with my gf (26) about a year ago. In the beginning she was a bit confused, since she is not really that domina kinda type. We didn’t speak about the topic so much. I asked her sometimes as she gave me a handjob about her past sex partners, if they had bigger dicks. She admited that there were 5-6 hung guys. I told her about my idea to buy a penis sleeve and she absolutley liked the idea. She has told me that she feels attracted to bit bigger dicks than mine (7×6), since they stretch her more and stimulate her deeper. And she honestly feels attracted to big sizes. So we started to use the penis sleeve sometimes and she absolutely liked it. She compares my dick to it likes to speak about the difference between the sensations with the sleeve and my dick. It absolutely turns me on. I bought her a pretty large dildo some months ago (about 8.5×7). She was happy about it and we used it once or twice. She told me about that sometimes she uses the dildo when im not there couse she is so turned on by the girth and the size.
I really enjoy that she is so open for my fetish and she plays that kinda size queen role.
My first question: Do you think she is just faking that she loves big dicks, just to statisfy my fetish? Or she truly likes it bigger?

I love it if she gives me handjob and blowjob after i fucked her with or without dildo and extender. I like to ask her about previous sex partners, about how short my dick is etc.

I need some new ideas humiliate to bring. Tell me some and if I like it, I will write in the tread what she reacted.
