Put benis IN bagina (or butt).V2 now with 50% more depth and 90% less filesize.Never could get proper balls-deep penetration to work with prompting, and the LORAs I found don't seem to work for me. This one doesn't work super well, either: it bleeds style, sometimes creates monstrosities, and is a little too rigid, but it's good enough usually.
Doesn't work too well with futanari and double penetration yet.
