I looked through the last few pages and didn't see an answer. Am I supposed to download chapters 1-10 (old) and then download the regular download (containing chapters 11-13) or how is this suppose to work? It's annoying that there are no instructions on the OP for this. Players can't read minds.
You have to archive chapters 1-10 (old). The chapters 11-13 would never work with it, because the old version is rewritten. So, you have to download the game from the link "Download". Having this full and new version of the game, you can complete this with the changes and with the new 14th, 15th etc. chaters.
By the way, your rating (criticism) is the best till now. Your proposals are enrich the game, so would greatly enrease it's quality and pleasure. I controvert only one of your example: ..." Anne fucks the shit out of a guy and either says that it was the best sex of her life (with you standing there) or the best orgasm she has ever had (with you standing there)"...
Sex is not always the best in the marriage, proven by the devorces and cheatings in real life. Of course sex mostly is the best with your partner during a given periode (before and/or after the marriage) or in a given time of life. Anne had the best sex with MC during and after university. Character of MC (his love, his suitability and intention to become her husband) probably contributed to her joy in sex at that time. But now, she discovered the joy of black penis again, and her vanity increases the joy of sex with the others (e.g. with Mike, the once upon a time star of the girls in the university, with the potent father of MC, with the nimble and young Eric, with the passoinate Brian, etc.) too. MC has nothing to do with, and can not to do against Anne's plain-spoken feelings, partly because that he has also his own separate cheatings and joys. You have right: rendering the sex of MC's are quite poorish in general, in spite of the fact that on the cuckolding route he has grater joy in Anne's sex with other man, than in sex with Anne. So true to nature getting only a BJ or even nothing from Anne during her account. But you have right again in the fact, that in general, Anne's accounts are rather clouse-mouthed. So there is a lot of possibility to make the game even better with the more feelings of MC, with teasings, with teasing foreplays with the girls, with their orgasms, and with multiple or "deadly" orgasms with the girls, as you suggested on the one hand, and to revive more of Anne's feelings, or more common experience of Anne's sex with other men, and only during the MC's sex with Anne on the other. This game is about a COUPLE (and not about mainly Anne) after all.
