Jun hid his feelings but I think Kazuma still Knew Jun loved him too, he was just clinging to the brother relationship out of fear, the only way past that is to push him out of his comfort zone. I don't think a blow job was traumatic in this particular setting I consider it forced consent.
There is no such thing as forced consent. Being assaulted IS traumatic, even if there are feelings there.
When in doubt..rationalize it away. It makes it easier to swallow. I told myself this...Miya say's they been going out 3 yrs..(middle school?) and that they were fuckin like rabits cause of puberty..so Mayu had a huge growth spurt..growth..spurt...
*lie to yourself... it's just better that way*
