This is so good, parts of this are just so funny, Especially the part where your mom catches you in bed with her best friend. The only issue I have is it’s old and the graphics are dated.


My Sister, My Roommate, My Mother will be part 2.

Wow, I really enjoyed this one. I started to think this was choice doesn’t matter in the long run game, but gladly was proven wrong. Thanks. I do want to know were you got the ‘asses’ for this ;P

This was a really good game I thought. The characters are good and the writing was really decent. I actually play these for the story and themes instead of the fapping but, there’s a ton of sex in it too. Good game overall.


Wow… How much of a faggot must you be to enjoy playing as a moronic faggot mc…
