Farewell, until the day I can see clear skies.

I won't lie. The first thing I thought of when I saw this topic was Ropeman. You've taken away my best choice.

But I do have a little something. It's been a while since I've read this author's work, but try Chitose Piyoko. If I recall correctly there are a lot of slutty ukes there.

Mind eraser, no chaser

An author that comes to mind is INABA Cozy. Both Boy x Angel and Under the Bridge. But they're just one shots.

Ooh! Ooh! Otona Keikenchi. The beta couple has a guy like this. Sleeps with girls and boys (at the same time). In fact, his seme refuses to sleep with him unless he can withold from sex for a week.
