Aisare Neko wo Hantoubun
Pussy King Sama no Akuheki
The slutty king can reverse roles. Typically a Seme in bed, he's only ever bottomed for a puppy-like chef who has enough energy and resilience to go after him. The king also fucks his main servant, with the excuse of getting him together with the other servant because he realizes they're in love with each other. It's kinda shitty, but all the characters are slutty and nobody got their feelings hurt so I guess that's ok.
Aisaretagari No Gemini
Onihebi Kyuai Monogatari
Supernatural 3some between a human, a snake spirit, and a demon spirit. Super hot, and of course the human couldn't choose between the two hot beings, so he ends up with BOTH!
sefure ijou, koibito miman!
This mangaka loves 3p and group sex. Multiple couples, someone is always a little loose at first though, to say the least. First couple - slutty Uke with many sex friends. There's one he likes the most for the sex, one day invites his twin brother to come along. The twin is the serious type and seriously fell for the Uke. He basically got the Uke to be with him exclusively using unmatched sex skills LOL
Chika-chan to!
