Restrain her

You don't want to have to fight her, so you pick up her discarded shirt from the floor, roll her on to her belly, and tie her arms behind her back.

Now you just have to wrestle her out of those tight jeans.

You flip her back over and hastily undo her button and zipper. You don't mean to be hasty but the idea of stuffing your dick inside her pussy makes your heart race and your mind run frantically. You lift her legs high to raise her butt up from the floor and then yank at her waist band, roughly removing those jeans. Her panties, the thin barrier of her heavenly folds, you simply pull at until they rip away.

Then you just stare. Her pussy is bare - seems to have been waxed. It glistens and draws you in - you simply have to lean down and taste it. You spread her legs and liberally explore with your mouth. It's the first time you seen or touched a women like this. For a moment there's twinge of shame that your first time is unrequited. But you remind yourself that you'll be able to stay out of trouble with your sharpie.

You penetrate her vaginal opening with the tip of your tongue, and you can't believe it's tightness. You barely feel like you can get your tongue in with this resistance. You try with your finger and find that that it's just as tight. How the hell is you giant cock going to fit in there?

You explore her slit some more with your tongue. Even finding her clitoral hood. You may be a virgin, but you know a bit. Stimulating this will expose her clit and turn her on. When she's turned on she'll produce natural lubricant and relax her kegels- sometimes even if unwillingly, and then her pussy will more easily accept your cock.

But you don't know if you want that. An unprepared pussy might feel even tighter - although it will surely hurt more for her. You could ruin her insides.
