Meeting my gf after a month. Suggestions for spicy session.

Hey everyone, hope you guys are having a lovely morning!

I am meeting my girl this weekend after a long time. We have one full day to us. We've been sexually involved for quite some time, however due to work commitments, haven't been able to get together.

She introduced me to rough sex, she loves it. "Fuck me like an animal" was one of her comments earlier on. I have started enjoying it too. One slap and turns into a submissive slut. I want to completely own her as my own personal slut.

Please suggest any idea of spicing it up. Preferably rough or dominating. Nothing too rough, like BDSM, not sure if she would be open for it without prior communication. Would really love to surprise her!

P.S - she has a great body. Above average big boobies, big ass and a slightly smaller waist.
