The Sissy Girlfriend Experiment is an erotic game with erotic text and images.
You will start as a male character living with your sister or stepsister. During one evening you will meet a woman who becomes your girlfriend. The story goes on and you will notice something: it's not a usual relationship. You can count on your friend (cis-male, cis-female, or trans-female) to help you through your journey.
Become a sex slave or a dominatrix. Maybe you will suit better as a husband? Or maybe as the perfect wife? How about becoming a prostitute? Choices matter, take different paths, use an assistant to help you through your goal, and during this journey, meet new characters with their own stories. Help them or make their life harder. Really, it's all up to you.

Why is there no game about fucking trannies instead of being one?
Because all this crap is super disgusting. Peddled by degenerate media that most people find disgusting. In other words no market.
No market? Lmao male on futa/shemale/lady boy/trans/trans vagina are very desired ya. Many fappers love jerking their cocks on these faps ya
Just a few freaks. Just because you are in an echo chamber of freaks on curated "social media". Doesn't mean most are into the garbage.
eyy I'm not into garbage u faps ya , I don't give a spit on ya, I sauce anon ya. What ya do ya? Ya cunt shtoop can ya
If you think this game is disgusting then why is your dumbass here? Unless you like disgusting things but in closet.. Do you wear your mommy's panties and use your daddies dildo on yourself?
Love this game but last updates are weird, dressing part is too complicated, i buy some clothes and can't wear them cuz requirements. Also Andy (sissy) story is forced, after what main character had with his misstress she was supoorting you and give you good advices she stuck into same shit?
Hah i just love that ignorance when somebody thumb down your comment without send reply why he/she don't like it xD
Single mom's did this.
No...no... Seriously, get a f'ing clue. Get a f'ing dictionary. "disgusting cuckolds" Not sure what being a bundle of wood has to do with ANYTHING.
so many trans chaser games, wtf is turning trans girls into a fetish?
They are all disgusting filthy faggots that's why! An abomination! A plague!
i hope you have a stroke and are unable to fap. that would be a fitting end to you, incel
Same that's happening with interracial sex, and cuckold stuff. They're just just trying to weaken manhood as a whole, it's really that simple. If you see a community saying they won't allow bullying and shaming, well, they've already lost their balls. Shaming and bullying is part of weeding out the weak, or toughening them up. Just look at the current young males, weak pussies, barely a single one able to do anything anymore.
On the plus side, the slightly over 18 females are pretty easy to fuck now, considering the lack of competition...
I open this game just to read the hilarious comments.
satanic panic is a myth. It never happened. A few people criticized the stuff. That is all. Totally blown out of proportion.
Look up, 39 Per Cent of 18-24 Year Olds Now Identify as LGBTQNow tell me there is no conspiracy to make you gay.
mikro plastics incrase the amount of developed estrogen in humans body which disturbs normal human hormonal cyckle
what a rabbit hole to go down. what are estrogenic chemicals exactly and what do they do? what do these studies even suggest?
It's a real thing. Plastics release a chemical that mimics estrogen. Especially when heated. Like bottle water in the sun. These along with other factors reduce testosterone in men. There have been studies with random testing and many men have lower levels than men much older due to these factors. Oh soy is another. Where you get "soy boy" term.
it's only real if you have no idea how this shit actually works. you've been eating soy your whole life, are you gay? i'm not
You're not... yet. Just like all poisons, you can make it happen over an extended amount of time, and not everyone reacts to it the same way in the same timeframe.
why would you look up such a statistic? are you part of that statistic? how does that statistic coorelate to a conspiracy?
The chemicals only release estrogen they don't cause your brain to become attracted to men now there are genetics involved that can cause a child in the womb to develop differently than normal increasing the chance to make them sexually attracted to men when they reach puberty so it's possible that it can affect children out of the womb as well since there are a lot of young gay and bi men who are lactose intolerant it's possible that soy milk could lead to that development
But that doesn't mean there is a conspiracy it just means we need to add a new factor to our children's diet and healthy development
I DON'T LIKE EM PUTTING CHEMICALS IN THE WATER THAT TURN THE FRIGGIN FROGS GAY!
Honestly, I think he was just controlled opposition, nothing more. Basically, if they're very popular well known, and seemingly dish out disturbing truth, but are still alive: they're controlled opposition. I mean, they can kill someone to make it look like a heart attack fairly easily... do you really believe they'd let someone become that powerful without taking care of it "discretely"?
this game helped me find my true self. i am one with the gay now. it has opened my eyes and my an*s. become one of us, don't deny it any longer you want it too
You know your asshole literally falls out when you get older. From all that butt sex. It's unnatural.
There is no conspiracy to make you gay, simple
BUUUT your life is a conspiracy against decency, good day to you š
Best game
