The Sissy Girlfriend Experiment

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.

Imagine being a dud and WANTING to be a sissy instead of a real man. This is what happens when women rule your society.

Imagine being honest and playing GTA. This is what happens when Jews rule your society.

get a clue

gates is Jewish? How about biden? Total nonsence.

Anonymous Fapper

Nearly all financial capitalists are Jews and absolutely all of them assosiated with Jews. This are the people who are in charge in capitalist world. Not Gates and definitely not Biden (he is a puppet like any politician).

Not true at all. Look up the top ten banks in the world. The majority are chinese.

They’re less than 2% of the US population and make up a sizable portion of America’s billionaires. I guess it’s be because they’re just super duper smart or something and definitely not because of nepotism.

The Jewish Bogey Man gonna get you! RUN!

Much more than America in the world. Also nobody makes you use their products or watch a movie they are in. The whole Jewish conspiracy crap is for low IQ morons. Jews don’t even like each other. They have a cultural affinity to education. Also they gravitated to banking, business and acting due to laws in Europe.

Is there a conspiracy to make blacks pro athletes in football and basketball? Only a moron would think there is and it’s the same thing.

Imagine still complaining about jews in 2023. Ever heard about the ISL4M virus? The middle-east variant especially, symptoms are quite violent and explosive.

It’s a trap!


Big pharma wants you gay so you spend $1000 on their drugs to keep you alive.
