This probably isn't the most exciting story but this happened a few years ago.

I was 26 at the time and my ex gf was 22. We never used condoms when we started having sex and I always came inside her. She was on birth control so we were always fine with it. She was adamant that she would keep a baby if she did get pregnant but since we were using protection, there was nothing to worry about.

About a week after we'd had sex and I'd given her about 3 creampies, my ex messaged me to let me know that she'd messed up her birth control and she hadn't been on protection during that time.

So for the next week or two I was feeling a combination of freaked out and thrilled. I hoped she wouldn't get pregnant because we were in no place to have a baby and hadn't been dating that long but part of me found it so hot that she might have just gotten pregnant.

She didn't get pregnant in the end but it unlocked a breeding kink in me and I'm no longer able to have sex without cumming inside. The thrill of burying my load and not knowing what will happen is too thrilling.
