  2. Enter the Futa-Verse! by Sex-Shooter

    1 year ago

    Explore the universe and it's wide array of life... Futa life. Ever since the great cataclysm, life around the universe developed in an odd way. Anything "male" died out and "females" evolved to the point where only Futas were left. Aliens across galaxies had developed into hermaphrodites, even the plant life became centered around that. And with that came the higher demand for debauchery. Oh, whats does this universe have in store?

  3. Undead Souls by Maikeru_Katari

    2 years ago

    In the near future of an alternate reality, a zombie virus has started to spread and begins a worldwide rampage. So it's time to grab your loved ones and survive in these soon to be hell infested lands or rise above and save the world. At the age of 21 do you have what it takes to live in this new world. The zombie apocalypse is almost upon you, do what you must to survive. (Based upon my love for zombies, HOTD, and interactive zombie games that I've played. Just a quick warning this story takes time to get to any juicy bits as I want to focus on the plot rather than any 'plot' if you catch my drift. Any-who, hope you enjoy!)

  4. The Bimbug by Testytesterton

    3 years ago

    A virus has begun sweeping the globe, infecting boys and turning them into sexy shemales with huge cocks, hungry holes, and irresistible cravings for sex. It is spread through cumming inside an infected sissy, or ingesting their cum. The good news is men are only infected if they have a sissy side to them, even if it's only a slight curiosity. So studs and real men have a virtual harem of bimbois to play with. The bad news is you aren't sure which you really are. There is only one way to find out for sure. Do you dare risk infection?

  6. Subjugation by Cantalope

    4 years ago

    You are a Tharn, part of an advanced alien race- well... not really. Your "race" is a sentient ball of slime that was able to take over the minds of an advanced alien race and you've been using them to take over the galaxy. Unfortunately, that takes a really long time to do. You're bored out of your mind until you find a pleasant little planet populated by a most entertaining race of primitives. Earth. (All pictures are more of a suggestion than how a character or scene actually looks.)
