Hmm.. You may want to try:
Katekyo! (Good art, smexy scenes, completed)
Koitomo?! (Parallel story of Katekyo ft. Cute seme but possessive)
You're my Loveprize in View Finder (yakuza, nosebleed ahead, good artwork, yes!, and a seme to die for. Yummy)
Yamamoto Kutetsuko's (if my spelling is right) manga is good too.
Enjoy! :)
