Futanari Planet

Planet Lust is a story-driven sci-fi eroge game with tight gameplay, mild horror, with action RPG and farming sim elements.
 
The player takes on the role of the game's protagonist, "Swan", who, due to unfortunate events, ends up at a military base on Mars with four beautiful women. You'll have lots of time to spend there. Better make the most of it!

Welcome to Venusty.
You crash-landed on a planet you were never supposed to reach. The atmosphere is breathable. The vegetation is familiar. The locals look human, speak your language, and greet strangers by asking to have sex with them.
You're a botanist. You were supposed to grow potatoes on an empty rock. Instead, you're the accidental centerpiece of a culture where casual sex is a routine social greeting — and you're the only one who thinks it's weird.
Planet of the Freesluts is a comedic adult visual novel about a stranded human botanist navigating an alien planet with radically open sexual customs. Read through 13 story chapters, meet a cast of 22 characters, and revisit every scene in the built-in gallery.
The tone is playful satire — Dekai's fish-out-of-water reactions to Venustian norms are the running joke, and every sexual encounter is enthusiastically consensual on both sides. No coercion, no drama, no darkness. Just a very confused human and a lot of surprisingly friendly locals.

Venusty is an alien world that mirrors Earth almost exactly — same trees, same birds, same modern cities — but its inhabitants evolved a radically sex-positive culture where physical intimacy is treated the way humans treat handshakes. Consent is a bedrock social rule, taught from childhood and reinforced every day; sex crime rates on Venusty are among the lowest in the known galaxy. Public affection is normal. Casual sex between strangers is a courtesy. A political candidate's campaign platform can literally include sex with her constituents. It's a world designed to make one specific human as awkward as possible.

The heroine of this story, Ayane is an alien girl from "The Pregnancy Planet".
She crashes into the protagonist's laboratory along with her space capsule.
Learning that Ayane's purpose is to come to Earth for mating and reproduction, the protagonist wholeheartedly offers his assistance.

It's a time when a faster-than-light substance has been discovered and humanity has migrated to Mars.
Suddenly, one day, an organisation lost contact with the centre.
They also found many unidentified life forms and tentacles wandering around the roadside.
Newcomer "Sasha" is a member of the Masta Zones (like a cosmic police force).
With the help of "Nabiko", she goes alone to the organisation to investigate...

No one ever explained to the woman why the acolytes of the holy temple of the Goddess needed to be virgins. Even though the temple was run only by women, all new acolytes had to be pure and virginal – and the reason would soon be revealed in this acolyte’s first ceremony!
