I know this game can be a frustration due to the excessive number of bugs, missing images and video sequences and game crashing errors and there isn't a bona fide walkthrough of how to do things in order to get the scenes or progress the main story (if there is any at this point).
The only thing I can help you all is by sharing a save for Creep path, which has all Megan's main quests done including the notorious Ami/Megan Sleepover, the Job quest and most if not all the sharing scenes. I do need to complete a lot of the University ones, and some of her pool ones (because due to bugs there was no way I could find her in any other swimsuit other than the playful bikini).
Most scenes of side characters are done except Tal's and Megan's in lecture class.
Also, Susan and Stacy are impregnated (by Calvin).
The save starts with Calvin in front of Chastity's house after her parents invited you for dinner. (In order to actually see the Chastity's house location on map, you will have to (be lucky) meet Chastity's mom, Gertrude, outside of the Clinic protesting about the abortions that take place in there.
Also, if you happen to visit the Clinic and you find Stacy there, don't click on her because it will result into an instant game crash.
Also, I have hired Stacy to clean Kevin's/Susan's house once per week (I think it is once per week) but I haven't seen the Kitchen scene yet.
I haven't triggered the Susan/Kevin/Calvin scene in kitchen (could be a Susan outfit issue and will have to test this as well)
So without further delay, full save for version 2.7.0
