Views: 1M

updated on Jul 03, 2025

The Sissy Girlfriend Experiment game - Your character has moved in with a sister to start a new life. But he's shy and has trouble even talking to women. However, the sister is just the opposite and has a lot of friends, and isn't shy at all. However, things will be looking up soon when you meet an older woman who becomes your girlfriend. The game has a weird mixture of genders from straight to gay to something in between with shemales. You only trust one person in the game, your friend, but all the characters somehow influence the results.

Optional: Cuckold, Cumplay, BSDM

          There are many things I've loved about this game for years! Some of the story paths and situations are SO HOT!! One thing I have never liked much and has only gotten worse with more systems, layers of systems, and interactions between systems is the economies (none of the wages anywhere make any sense). All of them have problems and none of them interact very well. As an example, I have never had a cursed item alter my body because by the time my prerequisite skill is high enough that body part is already maxed. With these core issues resolved this game would be more fun than frustrating and I'd fall in love all over again! ;)

              Did the diaper wetting ever get anything more, or is it just that one humiliation scene with the bully?

                    Below the screen there is square that has arrows pointing to its corners. You may click on that.

                      Hi there! Yes, you can have sex with the DJ. You've got to have a dick though and it has to be large. The only way I've done it is through buying a magical penis enlargement pill through the Dareboard store. You need 10 points though!
