Description: The main character of this game must start a new life in a new city with his sister after moving out of his parents' place. But he also happens to have a naturally shy personality, so he’s rather clueless when it comes to talking to hot women. He also doesn’t have that many friends, unlike his sister who seems to have a blossoming social and work life. You must help him get out of his shell so he can maybe get a girlfriend or two. The choices you make will influence what happens next, so you can have sex with girls, gays, and even shemales. Feel free to explore and satisfy whatever perverted curiosities you have in mind.

This was a huge disappointment. You REALLY should edit the starting options, they misled me to believe that i could actually play the game fighting against them to not become a sissy, i restarted the game like 5 times, i managed to fuck Stella and Sheyla, got a blowjob from Andy, and that's it. They were "one time" things, Sheyla didn't even give fucking skill. The plot stops progressing entirely if you don't become a sissy, i liked the challenge, but the game is rigged.

anon, yeah this game does not give freedom of choice or options. You either become a sissy slut, or you lose out on 90% of the gameplay/story. The "dominant" or "aggressive" "choices" result in end of every interactions. I stopped trying to play this last year, not gonna go back to it. The game literally puts you in a box, no reward for exploration.

anon, the game is literally called "The Sissy Girlfriend Experiment"... what did you expect??

us Earl @ 2022-09-13 23:41:44

THEsissy, Then what is the point of having "dominant" or "evil" attributes. It serves no purpose and you can literally do nothing with those stats. If you play any other game on this site it will give you 2 options (dom or sub) and you can see different scenes based on both choices. This game is whack as fuck, play lunars chosen or a struggle with sin instead.

I'm the OP and i came back to give another shot at this game, I think that it made significant improvement compared to when i tried it last time, you can now get through the game with a bit more of a rewarding experience if you just want a cis-experience and face the sissy stuff as a challenge to fight. t i know it doesn't make much sense to play a game that is intended for another audience, but i appreciate the effort and would love to see even more possibilities.

it Lotrum @ 2023-07-21 15:52:39

For that playstile, i think it would make sense to have some more earlygame accessible ways to train your fucking skill, maybe like paying someone for it, so that with enough effort, you can actually turn your fermale-fucking encounters into something not humiliating because you lack skills, would also love to see more positive feedback from fucking girls with high fucking skill, and a way to permanently increase dick size over medium, not saying huge, but at least big enough.

Is this game ever going to be finished. I love the except for a few things. Like no matter what you do you cant seem to get a bigger cock then average. I want me in the game to be a hot chick with a big cock. Everything thing else in the game is alright Im always hard while playing the game and have panties on and a plug in unless i have my vibrator.

Still not sure why the Instant Dick doesn't grow your cock. I know that being submissive will shrink it, but why does it do absolutely nothing when you have max dominance? Is there something I'm not doing right? Does the change happen over a period of time, or is it supposed to be instantaneous? Come on, I want to be a bombshell shemale dominatrix, dammit.

Reply View Replies

ca yk @ 2019-04-19 01:29:26

FruityGroovy, I don't think max sub or dom matters. After you take it you post on the forum and people respond saying "I can't believe people still fall for it" meaning either way your dick shrinks

Reply

gb Mr. Dill Doe @ 2019-04-21 22:43:22

Well if you are submissive it will go down but if you are dominant nothing will happen.

Reply

gb Anon @ 2019-08-20 22:26:12

FruityGroovy, well it actually does grow your penis, but only if your penis has shunk before. if it's max size and you use the instant dick it doesn't change.

Reply

us Larry @ 2022-05-25 20:29:47

FruityGroovy, this game is not built around dominant/agressive choices. The only choices you have are sub/shrink. If you try any dominant choices the scenario and paths literally end, and you cannot progress. The dev doesnt implement that option, thats why im never playing again. Exercising, studying, jobs....none of that means anything, you're forced to get tossed around 100% of the time.
