SAM-S: Space Intel

Samus Aran presses forward to locate a hidden base run by ruthless room pirates. Unbeknownst to her, you're the crucial guide - the person who can direct her every move with perfect, precise commands. And what will your price be for leading her through this perilous quest? Samus is laser-focused on her mission and ready to pay any price - but you might not be after a simple paycheck. Maybe you're after a reward much more carnal: to sink into the depths of her powerful, shapely body. Having come this close, retreat is off the table. The mission drives her, but the burning heat inside twists with temptation, waiting for the right moment. Every directive you give feeds her hunger and ferocity, drawing her deeper into enemy territory and closer to the edge of submission. Is your influence enough to claim her in every way? Step into the shadows where lust and danger collide. Samus’s steely gaze meets yours, a promise blazing within: her goals are set, yet her hunger grows. When the battle pauses and only the two of you remain, how will the night end? Take command, send her into the heart of darkness and desire. Taste the thrill as authority mingles with seduction. Can you master the battlefield and the bed? Now is your chance — don’t let it slip away. Samus Aran stalks a secret pirate stronghold hidden deep in space. You control her path through the shadows. What will you ask for when she’s within reach? Money? Glory? Or the taste of forbidden lust? She’s prepared to pay it all, but the stakes might just be higher than you imagined.

Celebrity Brothel

At the outset of the story, your role is a scientist working on exceptional interactive masks designed to morph any person into another person altogether. But fairly quickly, your project runs out of funding, leaving you struggling financially and forced to seek an alternative means to call home. Out of options, you come up with a risky scheme: why not launch a unique brothel where the selling point is that your masks allow ordinary women transform into their favorite celebrities? Of course, these aren’t real stars, but using your invention, the clients won’t be able to tell the difference. It’s a novel experience that could carve out a huge share of the market. And so the game starts, but how the story unfolds will be determined by the choices you make. Every move you take, every conversation you have, and every strategy you employ will direct the storyline. Will you build an empire based on illusion and desire, or will you fall victim to the dangerous undercurrents of this shadowy industry? Step into the shoes of this desperate genius and explore the possibilities of your creation. Manage your workforce carefully, tailor identities to please your clientele’s wildest fantasies. Balance trust and betrayal as you climb the ranks in this seedy world. Your path is yours to carve, whether you’re negotiating deals, expanding your business, or deciding who to trust with your secrets. The line between science and sin blurs as you walk a fine line between innovation and exploitation. Think you have what it takes? Enter this twisted tale of ambition, deception, and carnal pleasure — and write your own story in a game where identity is just a plaything.
