Stand fast! Carry on!

No! She might be acting confident, but you really feel like you've got the upper hand right now, she's just not letting it show. Besides, what are you going to do if you stop or slow down now? Go back to fighting Delilah with sex? That'd never work out in your favour. Not a chance!

You've been paying attention this whole time, as well. She's good at keeping it under wraps, but every now and then her mask slips, and you can see her secret blissed-out face for just a moment. You're sure you saw it! You'll carry on like this, and just wait and see whose body gives in first!

"So what, have you just totally given up now, or--"

Delilah's taunts get interrupted by the pause of a desperately-stifled moan as your kisses move back down to her neck, just over her voicebox. You can't see it, since you're so focused, but a bit above your eye level her cheeks redden ever-so-slightly, and her eyelids narrow just a little bit. Little by little, your warmth is melting away her icy scowl.

You push harder, making her blush even more. She brings one arm back from your pussy to weakly attempt to push your body off of hers, while the other arm remains draped over your lower back but is no longer doing its counterattack on your box. Your tender love is getting her all bashful, so much so that she seems to be forgetting that her hands are supposed to try and make you cum.

"Nng-- g-get, get off--- you........" Delilah's words disappear into a pleasant-sounding sigh, as she starts melting back into the floor underneath you. You take the opportunity to adjust your position on her to a more advantageous one mounting her leg, and she doesn't move to stop you, or do anything to prevent you from delivering more and more kisses to soften her up with. "Rrrrrrrrrrr...... hh!"

Delilah makes a noise that sounds like purring for just a second as her eyes close and her head rolls to the side, but soon cuts it off with a surprised-sounding inhale as her eyes shoot open. You lift your head from her neck just slightly to look at her.

"Is everything okay?" You ask meaningfully, almost forgetting the environment you're in. "That was a pretty weird sound just now."

Delilah doesn't answer, she just blushes an even deeper red and covers her face with both hands. Awww, it's actually sort of a cute reaction, and it makes you forget for a second just how much you strongly dislike this person. You almost just want to cuddle up against her and squeeze her tightly and forget about the whole competition. It's all you can do to fight the instinct to rub yourself back against her thigh and knee, but this is still a part of class after all, and you need to keep it professional.

Argh! You waited too long thinking she was cute! With your head raised and no longer giving her lots of kisses, Delilah's able to get to her senses enough that her arms regain their usual strength, and all at once she pushes you up off of her and rolls out from under you, making more distance between the two of you. Drat!

You turn to look at her, ready to carry on with your determination and purpose re-realised. At least it looks like your work wasn't for nothing, though, because Delilah's face is still all red and her breath seems to be coming a bit heavier. Actually, she looks almost dizzy.... but then it passes, and she's back to being just as laser-focused as you are.
