These scans come from kaifuu.com, which has several Sailor Moon doujinshi available for download in the "Comics and Manga" section (the site uses .cbr format for the files; if you don't have a program like CDisplay that you use for .cbr files, just change the file extensions to .rar and open them with a rar program like WinRar). I'm not posting the text story, freetalks, etc. from this doujinshi, so be sure to download it there if you want to see them.

"The Last Episode" (This strip is a spoof of a scene in the last episode of the anime.).
The outer senshi watch a shooting star together. Michiru wishes for Haruka to stop cheating on her. Haruka wishes for Michiru not to find out she's cheating on her. Setsuna and Hotaru both wish for -censored- with Chibiusa.
Then they all think to themselves that there's absolutely no way their wishes are going to come true.
"Sailor Team ni Onegai!" ("Ask the Sailor Team!")
From episode 115.
Uranus tells the inner senshi that they shouldn't let Hotaru near Chibiusa.
Then she transforms back into plainclothes, giving them a naked view of her from behind.
They all think to themselves that none of them is making a commotion over it. Jupiter wonders if she really saw what she thinks she did. Moon wonders would would happen if there were people in front of Haruka; she asks what's going on. Mercury thinks to herself that Haruka is guilty of public obscenity; she says that Haruka isn't a bad person. Venus thinks to herself that grown-up high-schoolers are a lot different from them. She says that she wonders if what Haruka said has something to do with their enemy. Mars thinks that everyone's remarks are pretty slapdash. She says, "I don't know."
"Neptune to Mercury ni Onegai!" ("Ask Neptune and Mercury!")
The second installment of "Suspicious Theater," the first installment of which was in a Studio Canopus book I've never read, Uwasa no Futari.
I don't get the first joke, but the second is that Michiru liked the taste of Haruka's blood (it's a spoof of that scene in Stars when Michiru sucks a piece of glass out of Haruka's hand).
The first strip on this page is "Not Very Suspicious Theater." It's the scene from Stars where Seiya comes into Michiru's dressing room and they flirt together. The joke here is that Michiru is more worried about what Haruka would do if she found out than what Seiya's fans would.
The story is continued in the next strip, "Jealousy Theater" (this is a play on words-- "jealousy" ("jerashii") ends with the same letters as "suspicious" ("ayashii")), in which Haruka comes into the dressing room, sees what's going on, and does a World Shaking on Seiya.
The next strip, "Not Suspicious Theater," continues the story. Michiru asks Haruka if she's jealous. Haruka says not really, since she already beat him up. Michiru says that Haruka doesn't know which one of them is really going to get beaten up.
The unconnected next-to-last strip on the page has Michiru bouncing a lemon on her violin during her concert with the Three Lights and Seiya wondering what the heck she is.
In the last strip, Michiru asks Haruka to help her change, then tells her she doesn't have to take her underwear off too.
"Spatter With Innocent Blood."
