Getting closer to the real thing [cuckold perspective] [true story]

So, since the beginning of college I've been really into the idea of getting cucked. I've brought it up in all 3 of my past relationships, but unfortunately was too pushy with the idea so it never happened.

I've been in a new relationship for almost a year now, and I've done a much better job with slowly introducing the idea. I first brought it up when, early in our relationship, we had to have sex on the floor because her bedframe was broken. I asked her how it happened and she admit it broke when she hooked up with a 6'6" guy while we were dating but not exclusive. She also admitted that his cock was bigger than mine. I told her that was really hot and I wish I was there to see it.

I started incorporating the idea of her fucking another guy into our dirty talk, and she started to get turned on by it. A few months into our relationship, we got a dildo a few inches bigger than me (I'm 5") and started using it on her. She was also into the idea of a guy fucking me, so she pegged me with the dildo too.

At the beginning of this year we got an even bigger 9" dildo. The first time she used it she came instantly and told me it was the hardest she ever came. Now that we have two dildos she's made me watch her get spitroasted by them, and even made me wear one of the dildos as a strap-on instead of using my cock.

We're about to make our biggest step to actual cuckolding today. Yesterday she sent me a nude of her in a see through top and a schoolgirl skirt. Today I asked her if she would post it to reddit, and surprisingly she agreed and told me to make an account for her. I immediately got hard.

When she gets home from work we're going to post the nude – I've been home touching myself for hours in anticipation. I'm really excited, but also nervous for all the doors this will open, and I also hope I won't end up being pushy again. Any advice is appreciated!
