About 18+ for Sci-fi builder

The 18+ DLC for the game Sci-fi builder will open you the world of explicit sexual content intended for adults only, the naked characters with genitals can have sex in dozens of different poses.

Characters in skimpy revealing outfits or completely naked in sex. Assign your NPC characters to get intimate with other NPC or objects in the room. Whether it be consensual straight, anal, lesbian or alien sex, these lovely characters are prepared to fully commit their bodies for your pleasure.

Customize the character's penis with settings to make it as perfect as you need: bigger, smaller, thicker, thinner or even monstrous. The characters from the main game have settings for everything: erection, flacid, glans, shaft and testicles. It will give you a complete freedom.
