Sam realized John and Dean fucked him in the same dominant style, but Dean was noticeably rougher. Also Dean loves biting him, while John preferres to kiss

people who claim that dean has never been physically or emotionally abusive to sam disgust me. what you are doing is actively trying to invalidate experience of victims of domestic abuse. the fact that dean and sam are siblings does not erase the abuse and power imbalance in their relationship.

This, having worked briefly as a crisis counsellor for victims of family abuse the relationship Dean has a classic control/abuse/ownership dynamic towards Sam that we see in abusive relationships. Sam has classic PTSD and withdrawal of an abuse victim. People who deny this are 100% invalidating victims of abuse and excusing it the same way the abuser does. It should not even be a discussion, let alone flat out denied by a large section of fandom.

Dean fucked Sam in a Full Nelson while standing, loving the way he could remind Sam and flex: “yeah, you’re big and tall, but I can still carry and fuck you without breaking a sweat.”
