Alright, you've found a quality gem. Congrats.

Some women get off on the fact that you are getting off by "using" her. Some women who like to be objectified enjoy being completely degraded. While other women prefer a softer gentler approach. Or somewhere in the middle.

But, more often than not, a woman who likes to be objectified, her Objectification Needle may sway from one end to the other, depending on how she's feeling. Depending on the woman and her kink(s) it might change anywhere from intruder anal rape kink to her saying she belongs to you. It just depends on the woman and how she's feeling.

I don't recommend the porn route. Unless you know her very specific kinks, I wouldn't rely on porn and even if you did know her kinks, I wouldn't recommend it. It's not her and it will feel disingenuos to her if you try something you saw in porn...especially given that you don't know where to start.

Start small. Gentle but not too gentle, grab a fistfull of her hair and press her into the wall, while behind her reach under and pet her pussy. If she says something like "take me" or "fuck me", grip harder and pet softer and ask "What?!" Make her say it multiple times until she's begging and saying please.

Make her watch herself in a mirror while you're giving her oral or fucking her. While fucking her make her tell you that her pussy is yours, etc. Usually, the demanding, but also calm and sweet at the same time, approach is a pretty safe bet until you two blossom together sharing your kinks.

Good luck.
