A 34 page PWP of Duo having his way with Heero with the use of toys. The drawings are kind of sketchy but it's not difficult to figure what's going on.

Yeah "paradise" is misspelled on the cover. One short (17 p.) PWP as Duo and Heero celebrate Christmas by saying "Marry Christmas" to each other and boinking each other like crazy. Pretty explicit, no masking of parts and where they are going. No black bar or white bar obscuring anything either. Can't say I like the way they are drawn, but if you just want it for the smut factor it doesn't really matter does it?

First story seems to be Trowa and Heero having a non-explicit yaoi moment. This follows with a story of the two standing in a field talking. It looks like Heero is breaking up with Trowa (but he really doesn't mean it). Trowa kisses him goodbye and leaves.
The last story has Heero tied to the headboard, being seduced by Duo (this yaoi is a touch more explicit than the earlier story. After Duo has his way it ends with Duo being left hog-tied and left on the bed alone. (At least Heero let the man keep his clothes on).
