If I were you I’d just ask her if there was anything she would be interested in trying, she would have a better idea at knowing what turns her on than any of us. Although I can suggest dropping hints or flirting throughout the day as a form of extended foreplay, a lot of women are into a long buildup
Kink play like dom/sub roles, restraints, fantasy role play. I personally recommend soft cotton rope over handcuffs. Lots of options, no tiny keys to loose, less likely to leave marks as long as you don’t tie it tight. Rope around 1-2 inches is ideal for beginners. Look for shibari rope but be careful if you experiment with any of the complex knotting down the road, always be safe & practice before you start trying to rig something complicated.
after seeing some context from ur other comments id totally recommend some doorway kinky stuff!! light bondage (even just tying her wrists w her panties or a tie or belt) is enough to spice it up a little, try fun different positions that doesnt include penetration exactly (like 69, or bending her over ur lap), try doing things in new and exciting places (maybe the woods, a bathroom, the shower😳)
Have a safe word that wouldn’t come up in natural conversation but is very easy to say in the moment. Stop shouldn’t be your safeword btw, it’s too short & it’s too easy to over look if distracted. If you’re exploring deeper into restraint such as gags make sure there’s some kind of impossible to miss “safe movement” that you two agree on. If you do explore communication and clear boundaries are two things that you both need to be really focused on. Enthusiastic consent is 👑.
Just communicate and start slow. A slipknot is easy to tie, so are rope handcuffs (watch YouTube.) If you’re not sure if you’re ready to buy $10 rope off of Amazon (go with silk or cotton, personally I find the cotton unbraided best especially for beginners because its easier to untie without the braid.) You can also use a men’s tie or a scarf. Oh and I meant to say 1/2 inch rope. 8mm can also work just be careful when you go smaller because it’s more likely to leave marks if you tie it tight.
A ratchet belt should be fine for a beginner, especially a fabric one as long as the rigger makes sure they can fit a finger behind the latch (just like how you measure a collar for a dog) especially one of the cheap canvas ones. And it shouldn’t be too hard to cut in an emergency.
Investing in some safety shears that get kept in the bedside table (the kind meant to cut bandages) is a good idea, I’d recommend sticking with slip knots and quick release knots to just get the illusion of restraint, safely but especially if exploring more serious restraints (consensually obvs) you definitely need to prepare.
