Is it normal stepdad slaps daughter's butt

Hmm...?
I can see why you see this as inappropriate.
That being said the way you describe this I don't think he's doing this to be sexual or inappropriate. I think this is his playful way of disciplining.
It's unusual but not necessarily wrong.

No its not bloody well normal.ffs.

I actually have a story for this one. My aunt use to slap my butt all the time as teasing when I was a child. I didn't like it one bit. I would tell her to stop, but being so young with a squeaky voice, she didn't take me seriously. So I had to sit down with her and tell her, "Please stop slapping my butt, it makes me really uncomfortable." She got upset that a 10 year old was having a sit down with her, but she stopped.

This is what your sister has to do to your stepfather and mother, at the same time. Even sit with her for emotional support, but let her do the talking, because they need to hear it from her. If the stepfather doesn't stop, then tell the mother.

He really should not be doing that since it's rude, but if that's all he does then I doubt he's a pedophile or anything. Fatherly figures do that sometimes and it's pretty normal. Don't bother reading into it too much unless he makes a move on her.

If he's ignoring the fact that she doesn't like it, he's either enjoying it sexually or as a power trip because she's a kid and he's an adult. Neither is healthy and he needs to be told clearly and firmly that she doesn't want him to do it any more, ditto your mother.

He should slip his hand down her pants and feel her bu properly.

It's ok and normal. Do it back to him, have some fun with this

My Step Daddy loves slapping both of my sisters pretty little asses

Slap that ass

So this is an old thread but it is very relevant to my current situation... Before I discuss my opinion.. I must ask.. As you did not answer before. Does your sister have a noticeably large butt? Do her cheeks show out the bottom of her shorts? Does she wear thongs or panties?

I was at a gathering at my sister's house, and, one of her now-ex's guy friends was there, commenting on the hot-bodied, teenage girls..Later saw him "jokingly" smack his own daughter's ass (she was wearing an admittedly sexy, little bikini bottom), telling her to cover up, or, he'd smack it again.. I know he enjoyed the ass-smack he did to her.. I would have, too, but, I wasn't her dad... He pretty much got away with smacking his own, hot little teen daughter's ass in front of a bunch of other guys..

I've sometimes wondered if he was waiting for the rest of us to join in, so we could all get one in on her..

I would like to lick your ass.

How old are you both now ?

I think it's certainly not normal.

Just curious does she have a big butt or is it bigger then your butt? It seems kinda weird that he would do it to one daughter and not the other. If she does have a bigger butt I would say that's the reason why he's slapping her. If you are about the same maybe that's just some sort of affection between the two of them. But hey if your sister doesn't mind it's no big deal.

Definitely not normal slapping young girls ass

It is wrong for him to slap her step daughters bottom she has told him she doesn't like it, the part that bothers me I your mother does it as well and knows about your dad doing it to her daughters, may be your mother doesn't think there is any harm in it or she is clueless, of may be she wants to share him around, don't like it at all
