Need advice about how to punish my sub
Using my alt here because I use my main account for business.
I've (M36) Been a member here for about a year, very dominant and generally alpha behaviour with my girl (F20).
Our relationship has always been quite dominant, but as we have gotten closer, she has become more submissive and is asking for things that are similar to a sub role.
She loves the smell of me, my armpits, cock, asshole, and has become more vocal about letting me know that doing it turns her on. Same for when I leave scratch marks on her and bruises. I also make her suck my toes and lick the soles of my feet. I also recently took her anal virginity, and she generally likes to feel pain (including the pain of anal).
Recently, as I have been away, she has been quite bratty and rude, and during a few times, she crossed the line. As we reconciled, I told her that when I come back in 1 week from now, I will punish her. She was happy to accept. When I told her what I was planning to do, making her kneel, kissing my feet, fucking her hard on her hands and knees so she bruises, she said that it didn't sound like much of a punishment.
So my question is, what can I do to take the punishment to the next level? She wants me to decide everything, including the outfit, and so, I would really like some help. While I am generally dominant, I don't have too much experience in terms of specific BDSM plays.
She's into nipple play, choking, me leaving marks on her skin, scratching. She said she wants to wear a collar and ears and me to make her my dog. Help would be genuinely appreciated
