Tribbing!

The two of you lock up against each other, pushing with hands and feet as you both struggle for a dominant position, but each both getting nowhere. Eventually in the struggle the foot you have pushing back against her hip slips past it, just as she uses one of her legs to pin down your other one into place. Like that, your legs start to get tangled up -- you're about to try to pull back and out of it when an idea hits you, and in a sudden flood of inspiration, you instead thrust your hips further forward and press your pussy up against hers.

"You--?" Delilah starts, then scoffs arrogantly and press right back at you with hers. She exudes confidence, and maybe slight indignation at the notion of you trying to take her pussy on with yours.

Without another word from either one of you, you both start lifting your hips to rub against each other, trying to counter the other one's movements with your own and get to an advantageous angle. It also has the effect of slicking up both of your crotches with juice.

Neither one of you said a thing, but you both know what you have to do to maintain your pride and prove that your pussy is better. You and Delilah have your jaws clamped and your lips pressed tightly shut, determined to not be the one who makes the first noise in reaction to the growing feelings in your sexes, and equally determined to make the other one give in first and take the lead.

This is really dangerous, and you know it, but at least it's dangerous for both of you. There's no way either one of you gets out of this unaffected. But you refuse to be the one to disengage -- too much of your pride's on the line for that, and even without saying anything, Delilah's made it clear that she doesn't think you're up to the challenge here. It's a big risk, putting your pussy right up against one like hers and hoping to win, but you have to take it!

The two of you lock eyes, and silently agree to pull away from each other and slide your panties down just enough to reengage properly. As your pussies make full unrestricted contact, you both simultaneously let out a deep groan and start arching your backs shamelessly, instantly wracked by electric pleasure. It's... it's good!!

Your motions slow significantly as your muscles start going weak and your arched backs relax just a little, though they still remain off the ground. You groan again, or maybe Delilah does, forgetting where you are for a moment and just enjoying the feeling of her soft lips pulling back your pussy folds as you slide across each other. Every now and then your pussy gets opened up to the cool Gymnasium air, which feels extra exciting and just makes your body betray you more and more each time.... at least Delilah seems to be feeling it too, though, because- NNGK!

At the exact same time, a pulse of pleasure runs through both of you, drawing a sudden "Nng!" and a short-lived reignition of tenseness before your legs go all rubbery, and the two of you fall into a sweaty, breathless heap entwined and tangled up together.

Gasping, you're able to slowly drag yourself back and away from her with your elbows, getting some of the distance you need to recover. It feels like she's doing something similar, though you can't be sure, since you're stuck staring up at the ceiling. Soon though, far sooner than you would have liked, you will yourself to sit up in a kneeling position and see Delilah already up across from you, face red and breath heavy.

As predicted, it took a lot out of both of you. You just hope that this mutually-assured-destruction worked more in your favour than it did hers.....
