even if this might be "made up", which we don't know, it is still and interesting question. Several times people have asked questions about bros doing stuff together. As some have said here ... it could be totally honest curiosity by the younger bro, he could have sneaked to see his bro working his meat and is totally curious and possibly infatuated by him. And if they have a open family relationship and have talked sex, crazy stuff before, maybe the younger felt he could mention/ approach the big bro about it. Hey, the younger bro could actually be bi or gay ... we are not told. So please don't crucify the guy for asking his big bro; it probably took a lot of balls to ask. And please get off your high horses about the incest crap. They are just bros ... possibly innocent experimenting. So the big bro is surprised and embarrassed? Then maybe he should just chat with him ... big bro to little bro ... and talk more about sex ... why does he wanna wank with him? Has he seen him before? Is he just curious? Has he done anything with other guys or maybe girls? Just get it out there since the can of worms is already open. But don't make the little bro feel like a criminal either ... or the big bro either. It's innocent wanking, not murder.
