I told my gf that I've dated for a year and a half about my kink involving hotwifing and she said she was not really into the actual idea of sleeping with someone else and doing the flirting and all that but that shes okay trying some stuff like roleplay and introducing toys and that she'll keep an open mind. So we got this rabbit vibrator toy that she like using as a vibrator but didn't really like actually having it in her. She said it just felt weird. So then that kinda stopped except for using it as a vibrator. She also started telling me fake scenarios while she jacked me off although she was iffy about that one cause she thinks she's bad at it. So then I introduced the idea of a penis sleeve cause she had told me one day about how the reason she thinks she didn't like having the rabbit toy in her is because it's just a toy and it felt weird. And she was okay with it and actually got a little excited Wich made me excited and we shopped for one and we got in over our heads and got one too big like a 8inch see through one and the first time we used it she said it felt good for like a minute and then it just hurt once I started thrusting so we had to stop. She managed to get alot of it in too Wich was hot. So after a couple more tries and fails with the the Extender it kind of died of and she went through alot of personal stuff and wasn't in the right mental state for anything sexual. So our sex life died off for a couple months. And although it was hot her not being even a little interested in those 2 months it was TOUGH there was many times where she seemed perfectly fine and flirty and i would think she was in the mood and she would turn me down. But then she got better but still not wanting sex. HOWEVER I asked her what If I got her off even if there was nothing in it for me. (I just needed to be intimate with her even i couldn't anymore) And to my surprise she obliged and so I started kissing her and rubbing her clit passionately with my hand on her tits. Then I start kissing her down her neck to her boobs and her body and start eating her out and she gets really turned on and starts grabbing my head. After about 3 minutes I stop look up and tell her I have an idea and I grab the rabbit vibrator (and she is soaking wet at this point) abd put in her and start thrusting it inside of her while I eat her out and she starts moaning and moving in ways that I haven't seen in months and then she says she js getting close and she comes. She immediately giggled a little and turns away and covers herself up with an embarrassed face. Immediately knew that she fucking LOVED it. So after all smug I ask her if she liked it. She laughs and says obviously. So I ask her if she liked it more than when we have sex. And she was being shy and to say It was a different type of feeling blah blah.. nah I asked to be serious did she like it more than me and she said yes and squirmed a little and asked is that okay with a little smile in her eyes. And in my head I'm like "DUH THE FUCK??" and so I told her that yeah it's okay it's my whole kink. And we talked about afterwards and everything and she said she still feels the same about the kink and doesn't know if she is okay to have sex again mentally yet, but is down to try that combo again

This happened tonight and IDK what to do I'm happy but also not 100% certain if she really is into this. Cause also everything we've tried and almost every time we talk about this kink I bring it up. So I don't know. I'm thinking maybe seeing if we start having sex again (in the next few weeks) and introduce the idea of a smaller extender that she could handle but still bigger than me.

Also for background I'm her first everything,kiss virginity, date, everything. She had never talked to a guy or anything before me.

Any tips for what to do next that could her open up to it more?
