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.

NewSiSco:
- Lab Assistant - Vanessa (Crimson Eyes) doesn't mind having a Lab Assistant, and Andrew (your perv neighbour) is looking for a job. How will that work? Your sissy neighbour is willing to do anything and seems to enjoy this new gig. So many machines to try...
- Andrew's changes: Andrew's personality and body will change after a few experiments, but first, you need to help the new assistant, try their candy selections.
- Each personality will trigger a different weekend event. Try them all! Big/Small dick, Big/Small breasts, Dominant or Submissive, all sorts of Andrews to play with it!

the task challenge Does it exist in real live

We need a android version please
I really love this game, so much so that I had an entire free day to do anything I wanted and I jerked off for the entire day playing this game. Highly recommend this game.
Indeed great game! My balls are also empty from jacking off. Love the concept of the game!
Is there a game just like this one here?
If you mean the Text based stuff "hornstown" is similar where you also can transform and play as a sissy/trans/bimbo. Or if you mean the Sissy stuff I recommend "Earn your freedom" but that one is mostly linear, and the Transform stuff is in its early stages.
it looks really promising and hot, gotta say much better than the other games here
The only thing I would change is the draw of the MC: also when your body changes, you don't see it really well with many clothes.
The story, on the other side, is a dream for a sissy!
i can't open the game, the exe file is not there , anyone can help ??
does the mc bang or be banged
