Maybe it feels too good?
Its cause since kyon likes lucaon he thinks he doesnt like him back and that he only wants to have sex with him
Well, few chapters back I also wondered that but then someone posted how lucaon smashed the elevator door with no effort whatsoever plus all the ripped clothes and belts, now imagine the sex and a handjob ... must be very painful indeed :D jokes aside,... I do think he cries out of love not from pain... sometimes even men cry when they feel really good during sex :P
He cries because its just sex with no feelings
It's definitely because it feels good. C'mon guys, have you never read yaoi before???
They're allways crying and drooling uncontrollably (in my opion waaaaay too much... C'mon, it doesn't feel THAT good) because it feels good ε=ε=(ノ≧∇≦)ノ
I think it is a combination of things, mostly relief. First, many ukes cry for pleasure during sex--but I think there were more tears after Lucaon said, "I know. Don't worry." and when Lucaon was holding Kyon with Kyon's head tucked into Lucaon's chest. Kyon was blushing and worried at the beginning when Lucaon teased him and Kyon could not move, and he enjoyed the sex--with only the usual small tears.Now Kyon is helpless, but being held--almost the way Lucaon had held him as he cried when he was a child, but way sexier. Lucaon is cradling him (while fucking him, sure) and patting his head--even kissing the top of his hair lightly. I think Kyon is relieved and happy and letting it all out since he has no strength to do anything else.
I still dont get it, why is he crying? Is it painful having sex with lucaon? , or maybe he really doesnt want to have sex with him? What is it? Im really confused ,why is he crying while fucked by the guy he likes, someone enlight me please!
