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.

You know, if you gays would take a break from random hook ups for a couple months monkeypox would end.
With the way this bitch talks, I can see why she has no luck with boyfriends, talk that way with me and she would already lost some the ability to talk.
I open the gay/trans games just to read the comments. Hilarious!
Perfect gifts for a gay person.
Drugs like valtrex, truvada and prozac.knee padsbreath mints (cock breath)hemorrhoid creamposter of harvey milklubea dressa gift certificate to grinder  :wpds_unamused: 
@truth you seem to know exactly what is a perfect gift for a gay and you post on a trans/gay game... It's time to accept the truth, truth.
That I like mocking you and am trying to enlighten you at the same time?
If mental illnesses were truly curable, we wouldn't need to have lunatics in there until they die. Don't bother with them, you're wasting your time.
A hero to homos who groomed young men. From san fran of course. They made a movie for him and named a naval ship after him. He actually liked to target young sailors so that's ironic (or intentional).
I dont know wich comments make me laugh more, transphobic ones or homophobic ones
But thank you all to bring me smile and happiness from your lack of intelligence and the quality of your writings, so much potential nobel prizes.... XD XD XD
Seeing something as immoral or unhealthy is not a phobia. Now you could say going on a date with what you think is a woman and have a dick pop out would be something you should fear today. But that's not irrational as there are a lot of nut jobs running loose and the many are pushing that garbage. Still that's not an irrational phobia. So phobe doesn't count. Just made up bs to push an agenda.
^Unfortunately, I'm stupidophobe, so if you could keep your comments to yourself, Mr. isgay, that would be for the better š”
No problem, I'll stop commenting when the grooming stops. When every icon in history and pop colture isn't represented as gay. Like how they are trying to say Lincoln is gay or changing Superman and Batman to gay. When kids shows and the schools are not trying to groom. Lets not forget esg score that pressures companies to push gay grooming on it's workers and corporations.
jesus all these redditors in the comments please, go die in a cesspool no one cares about how you try to enlighten some dumbfucks with you one top of them just more ignorant
Big pharma wants you gay so you spend $1000 on their drugs to keep you alive.
in some countries theres health and social care systems yknow.... tho USA is the cesspool of greed and capitalism, what you said could probs be applied to them, i give you that
Somebody is paying in socialized medicine. I'm sure the gov don't produce medications.
You queers are very underhanded. Impersonation and lying should be expected by immoral groomers however.
