Long story so bear with me, tldr at the end.

As the title states, she creamed for the first time on a toy much bigger than me. And I feel a rush if mixed emotions.

I'll start by saying I'm not small by most girls standards. 8 inches and a bit above average thickness. My gf had never been with a guy as close to my size, but over time she's gotten accustomed to me and takes it very well, and we have started to branch out and try some bigger toys. And even done some light fisting. She usually cums at least 5 times from our piv sex if not far more. She loves dirty talking about cuckolding and is insanely attracted to black men, and has always wanted to try a BBC.

Setting: we were staying out of town in a hotel. I decided to bring a toy we've only used once before, and had to stop bc it hurt, but she came on it the second it went inside her.

The toy: a black cock sleeve that's about 11 inches of insertable length, and wayy thicker than me. I can't close my fingers around it, and there's an inch between my thumb and middle finger when I try, and I have good sized hands.

Since the first time we tried it, she's gotten to play with some bigger toys, and we have gotten to the point where we dirty talk about cuckolding constantly. She told me she wanted to try it again. She loves to compare my cock to others who message our pages, and make fun of me. When I put it on and secured myself into it, she sat there holding it while telling me how much thicker and heavier it felt than mine, and I got rock hard inside it instantly. I slowly started sliding it in with lots of lube and some dirty talk. The head popped in and her eyes rolled back, she told me that just the head felt better than my whole cock, and I thought I was going to pass out from how turned on I was.

I finally got the whole thing in and she was in sheer fucking ecstasy. She was moaning, gasping, grinding into me in missionary. She kept begging for more and within a minute she was begging for the whole thing... and she took it like it was nothing. She was squirting non-stop, taking the entire thing inside her. Saying intense dirty things to me, telling me it felt so much better, and that she wished it was real so she could feel it pulsing.

We switched to riding and she went feral. She said it was nice not having to worry about it falling out on accident like my dick did and i got rock hard again, and while she was bouncing on me, she covered the toy in her cream. Something she'd never done on my dick. She finally said she'd had enough after roughly 30 minutes and wanted to feel me again. She lost count of how many times she came, and at one point said her orgasm lasted over 5 minutes.

I took off the toy and went into her. She started whining while I fucked her, I was harder than I'd ever been in my life. I asked her what was wrong and she told me she couldn't feel me, not at all, not in the slightest, not even when I barely managed to hit her cervix ( first time I've had trouble hitting it). She told me she wished I was as big as that black cock sleeve and I blew inside of her. Then she sat on my face and the cum immediately started pouring back out of her and into my mouth.

It's been two weeks and she doesn't react as much to my cock anymore. I barely make her cum, and she's constantly hinting she wants something bigger again. On one hand it's so hot I lose control thinking about it, but on the other hand, I don't want her to do away with my cock completely... should I just give her what she wants???

Tldr gf tried a massive toy and now I'm worried I'm not enough.

Edit, thank you all for the support! If you want to dm me to ask questions feel free!
