These are from a game called 'The Copycat'. It's a typical Mom/Bully NTR. I have only uploaded the pics which contain the MILF Gretchen. These are in chronological order. If you want the whole story, play the game. And support the artist.
Played the game, and I have to say this isn't all the images that have to deal with Gretchen Goodman. Quite a few of them are missing though from what I have seen quite a few of the bad ends are within these pics.
