Onna31's manga / #Incest Yaoi(41)

Yuu can't take it anymore, Shiro bress look so tempting. So he attack him at the bath

Maria Boy Vol.1 Ch.2.5 older brother likes not shuu but his younger brother is a way that is a bit more than brotherly. Thus his stalkerishness. He was sex friends with shuu who was a substitute of his desires, and because like you said, he wanted attention. Then he finds out that the little bro and shuu are together when he listens to the audio of the bug the little bro had in his bag when the latter and shuu had their first sexual encounter. This flips a switch and he goes back to his old lover who does all kinds of terrible things to him and get him all bruised up (but like he says, its nothing compared to the pain inside). He uses his hurt state to attract the younger bros attention, and when this doesn't work he calls shuu and flirts with him, once again to attract the little bros attention (which still fails...). Then the little bro tells the big bro to stop chaining himself to him and to live his life, and the big bro (literally) tries to escape from the truth in those words
