Monster Girl Inn - The Complete Trilogy

I would say Lakeside Cougars would be a very decent place to start, and it has a lot of sex scenes. However, Our Own Way seems more universally liked, and also is much longer, and also has a lot of sex scenes, and is closer to what could be called an erotica. (Even though it could survive if the sex scenes were removed.) (Well, okay, if I'm being totally honest...book six would probably not stand up to this particular scrutiny...it had like 11 sex scenes.) (It felt necessary, though, and I still stand by the decision.) If you're looking for something with a more fantasy flavor, you could try Goblin Girls Do It Better or Monster Girl Inn. Both have more emphasis on relationship, and thus sex. And there's a lot of other girls pulled into bed, too. If you're looking for a more post-apocalyptic flavor, Down the Rabbit Hole is very sex-scene laden. It is societal-collapse iseaki flavored. A Warm Place is frozen apocalypse very-near-future flavored. And Haven is more 'zombie apocalypse town-building with some fantasy sprinkled in' flavored. Both were written back when I was still trying to fine-tune the sex-to-story ratio, and I still thought I needed way more sex scenes that I actually did, so both of these series do have stories, but there's like a lot of sex scenes. Also, if you want stuff that's more just straight-up erotica, either sci-fi, fantasy, post-apocalyptic, or paranormal romance flavored.
