hey, i read a wincest one-shot a while back. Sam is in a relationship with Dean, but it is a semi-unwillingly one. it is written partially from Sam's point of view and he talks about how Dean 'rapes' him. he allows it to continue but he is slowly tearing up.
i remember one part where Dean goes over the line and there was blood. that was it for Sam and he storms into the bathroom. dean later comes in and with unbelievable gentleness, he cleans Sam up.
later Sam and Dean reconcile and they are good, with Sam in a healthy relationship with Dean.
did that make any sense?
anyways, that is all i can remember
i would also welcome any other recs related to this aspect
cheers,
stompy
