Grandma's House. I actually enjoyed the first few updates and some of the LIs, but each release adds a few more characters that exist solely to cater to a specific fetish. The writing also got extremely repetitive, especially the sex scenes, which have some of the most boring, clinical...
It took me about 6.5 hours to get to 500 on Sunday evening, but I didn't have any plans and was just fucking around on the internet anyway. It took me about 1.5 days to get to my second 500. Commenting more will boost your coins faster than just reacting since you get coins for writing it AND...
She had an astronomically rare genetic condition that caused her to have a fully developed reproductive system at birth, though. Most girls don't have their first menstruation until they're around 11-13.
Strive for Power is similar in the sense that you can capture and train an endless number of slaves and is mostly text-based.
Fort of Chains is a similar slave training/city building (or fort building in this case) game loop.
Tales From the Unending Void by Perverteer has a trans girl and a futa alien (it's a scifi game) that I believe both have the option to let the MC receive what they have to give.
Midlife Crisis is another game has a trans LI that the MC can receive from.
father-daughter takes the #1 spot, followed closely by brother-sister. Uncle-niece is #3. I'm generally not much into older women/younger men pairings unless they are part of an incest harem. If it's just mother/son or aunt/nephew I don't really care much at all.
I can't remember the exact first one I played since it was over 20 years ago but I stumbled across a random sketchy website with hundreds of lewd Flash games. There's no telling how many viruses I put on to my parents' computer from that site, lol.
Getting the skills to create high quality renders like SSP takes a long time, and building a rig capable of rendering them in a reasonable amount of time takes several thousand dollars. As nice as it is to get beautiful images in your AVNs, quality writing and/or solid gameplay can really...
To get access to the Games+ section you need to be active on the forum. Liking posts, commenting, starting threads, logging in, etc. all earn you a few LC coins. When you have 500 of them you can spend them to buy access to Games+. You can also purchase them with real money if you want to skip...
The Sims franchise has a ton of NSFW mods. I'm not sure I'd ever use them for Sims 1 or 2, kind of hard to fap to those 12 polygon sims, but I know 3 and 4 have a bunch too. The Sims 4 base game is free, too.
Like most of the other members I agree that single digit numbers of well developed love interests is better than an endless cascade of random non-characters.
