Go to the asstr/kristen pages and you will find TONS that you will love. If you go to "links" and spend a bit of time browsing, you'll be amazed at all the D-d love content you'll find. Sorry to be so non-specific, but I hate to give a specific lead and for you to miss so many other good stories.
This is also a favorite category for me, and I find the links through Kristen to be a gold mine. Unfortunately, it takes a while to do all the browsing, but I am confidant that you will be well pleased. There will be stories of all ages, and everything from love stories to forced.
Another outlet you might try is MrDoubleena.com. I opened a membership there years ago...it is updated daily with a variety of stories. Unfortunately the updates require a very modest membership fee, but there are also several free archive areas I believe you may really enjoy.
Good luck to you, and happy trolling.
