Is it normal i treat my niece like a dominatrix?

Although shes only my niece "in law" it still feels.....mischievous.When she was young,i subtly showed her that i would do anything she said.It started out just getting her drinks and things like that.I would spoil her any way i could.We had a weird bond because we were the only redheads in the family.Things began to escalate.

Long story short i started encouraging her to hit me.She would leave some kind of serious bruises on me in a sort of playful way,which we would have no explanation to tell the family.They would get really mad at her when she would say "he likes it".

Things like that went on for a while and it escalated again when she got a little older she started to realize that i was very submissive to women i liked.She found some really deviant pornography i was looking at in my search history.All women-dominant stuff.Women peeing on men.Women farting on men.Women raping men more or less.Then One day soon after that she really called me out on my submissiveness and started giving me commands in front of her friends."sit"."on your knees".Stuff like that.I knew it made her uncomfortable how submissive i was to her when we were alone.It really solidified in her mind that i wouldn't disobey her but im sure she really didnt like it was sexual for me.

She confronted me outright and said you better not be trying to "get at" me.she asked something like"what is your REAL intent?.what are you trying to do?be completely honest.i know your trying to do something".So i told her all i really wanted to do was kiss,lick and sniff her everywhere below the belly button,which was the truth but when i said that i was"wimpering" like an injured animal.

I dont remember exactly what she said but it was along the lines that i was a psychopath child molester basically.She gave me a look that made me feel so much shame i almost cried and for days she barely said a word to me but then it happened.There was a brief moment where the family had gone to the store and as soon as we were alone she ordered me to lay on my back on the floor.She sat on my face,full weight,no mercy and started yelling "drown...drown!".long story short again she forced oral and was VERY rude and aggressive.Just how I wanted it.

Now i basically let her do anything any chance we get and shes really mean about it.For example,I buy her these expensive leggings because it makes her butt look sooo nice but then she ruins them on purpose by "finishing" in them when she humps my face.She takes a LONG time.She made my lips bleed on several occasions.Shes short with smallish boobs but has this bottom-heaviness that i LOVE.She started taking a liking to farting on me(one of my favorite deviant things) and she threatens to do other deviant things,much to my delight.I have licked her butt,her feet,her armpit.I let her spit in my face.She hits me all the time in front of friends and family and they jump on her about it.She will make me take her shoes off.She will make me get her drink when its right next to her.These days i dont really disobey her in any way and the family KNOWS we do something but they dont have any solid proof.

I have girlfriends and she has boyfriends but every now and then she dominates me still.Its always 100% for her pleasure.She has never seen or touched my penis and i have never penetrated her with anything besides my tongue.Aside from sniffing and licking her armpit she says im not allowed to touch her above the belly button. Literally i cry tears of happiness sometimes when i go down on her or when she gives me a really harsh command,like sniffing her sweaty butt after soccer practice.I know all thats probably not normal but what do you think?.I think redheads are deviants
