In Booty Farm, you're a playboy who takes over his late uncle's farm. Selling the property seems appealing at first, but then you realize it's sitting in a cock-depraved area full of hot farmhand babes that you can hire and fuck while working the land.
This game is very similar to Facebook's FarmVille, except that it offers a few additional layers of gameplay with visual novel type interactions and multiple choice conversations with a dozen different girls, each with their own story. Moreover, there are lots of sexual innuendos throughout the game, but no animated sex scenes, and you need to play for a few hours before seeing any hardcore artwork, but at least it is well done and in a western porn comic style. There's also no interactive sex gameplay, so you'll mostly be farming which might not appeal to everyone.
Coins are the in-game currency with which you shop and expand your farm in a variety of ways. There's also a premium currency in the form of diamonds that speed up each process. This brings us to the fact that while Booty Farm is free-to-play, it also nudges you to spend real money. However, you can be Scrooge McDuck and save your cash if you're content with playing about 5-10 minutes at a time while doing something else in another tab.
Overall, there's not a lot of depth to the gameplay, and it doesn't offer a lot of porn either, but that doesn't stop it from being fun or addictive. And because Booty Farm is free, it doesn't cost anything to try and see if you like it.
