I Encourage My Girlfriend To Fantasize

My girlfriend has never been all that sexual, in fact she's a bit inexperienced, despite being a little bit older than me, by about 2 years, anyway, as we've been together for the past 3 years, I've slowly been encouraging her to fantasize, explore and try out different kinks she's never heard of or never knew she had.
I have shown her gangbang porn, and she's been having multiple gangbang fantasies, sometimes she'll imagine herself fucking a hot celebrity she enjoys watching on TV, or some model she saw, and I full on encourage it. She usually likes to involve me though, and when we do have sex I tell her things in the heat of the moment like "This Person" is fucking you so roughly, and she just loses her mind. I also describe how many cocks are surrounding her and I tell her to imagine it.
I've even bought her a dildo that's bigger than my cock, Tied it down to a pillow, tied her up and let her fuck it endlessly whilst jacking off to her and cumming all over her nude body. We have so much fun together and I want to find newer ways to make each experience intense.
We should be watching a movie with her favorite actor in soon and I plan to finger her or touch her all over when he's on screen. I enjoy teasing her.
