Ardoni and Crom realized some comic storieswith couples. Also Flyingfur created some 3d stories involving men and women fucking/fighting.
Do you have any inks to images or sites? Tried googling their names but can't find anything by Crom.
Ardoni has been inactive in the last few years, can only find censored previews for his old blog.
Flyingfyur created some awesome images he shared here as well, but I can't find much more.
