Ikujinashi No Spectator
Thirsty for Love
What did I just read? There is boyxboy physical action, but no boyxboy love. All three guys are in love with the same girl and this leads to lots of sex between them, but there's no love between the guys. Therefore I'm not sure I really consider this a yaoi. It's more like a Shojo with a heaping side dish if gay porn.

Different, in a good way. Don't like the brother though, he is so cruel to brainwash him like that, pure emotional abuse. And if you read his spin-off it's even more horrifying because he becomes extremely physically abusive as well...
