Circle is Johnko Arashi. Published 1996.
Chibi Duo walking around in a bunny suit (why?) coerces and has his way with a chibi Heero. Very frightening (at least to me) ^__^
Second PWP has Duo trying to entice his neko Heero with strawberries and cream. Duo, be careful what you wish for!
Circle is Mizuki Takami/Tsugumi Nanjyo Union Book (Clio). Published 1997.
Yep, it's a Heero x Quatre book. First story, everyone is on the Peacemillion and Quatre decides after having an erotic dream about Heero to tell him of his feelings. It seems that Heero had similar feelings? Well, they shared a kiss and held hands while Quatre slept, you tell me.
Next story is an AU. Quatre is a rich boy who is lonely and seeks out the company of Heero. They hide out from Quatre's sister Iria and have some up close and personal quality time.
Circle is Mirin Resort Kingdom. Published 1995.
Several short funny gags that put a different spin of scenes from the series.
Trowa tries to bring home an injured Heero from when he self-destructed but Catherine doesn't want to let him in because she's "entertaining" the CircusMaster. Or Trowa bopping Quatre on the head with his flute when they performed their duet on the show. Very silly.
Circle is Ayanosuke Hazuki. Published 1997.
It's a continuation of the MAX series. Where Heero seems to get his rocks off abusing Duo. This part is no exception.
They are undercover at a school and Heero is perpetually raping Duo. Duo talks about his life before with Sister Helen. And for some unknown reason cares for Heero, who seems to use him and leave him. Not my cup of tea, so I doubt I'll ever get the others in this series.
Circle is X3 (Yutaka Miyabi). Published 1995.
Lots of pictures of Naked Trowa in this (is that a bad thing?) Catherine seems to have less than sisterly feelings for the boy as she is constantly pouncing on him on almost every page.
Then there's a weird little story with Trowa and Quatre dressed up as victorian ladies. Why? Got me. But there is a beautiful color pull out (no, he's not naked in it) but I'm so tempted to tear it out and put it on my wall.
Circle is Incubate (F. Pessona). Published 1996.
The inside cover says it's a Heero x Trowa, but it seems rather shounen-ai to me. First story has the boys captive with Trowa as Oz soldier. He takes Heero out of the cell. They have a few words while walking down the hallway. At one point Heero grabs him in a threatening manner. Next thing you know Heero is hugging him (well as best as one can hug with their hands bound).
The second story, Quatre keeps envisioning Trowa walking with bloody feet. He's telling this vision to Duo. Then there are some angel like drawings of Trowa. So ... got me!
