Hands to pussy, go!

There's nothing else for it -- if she's having this much of an effect on you, then you can't waste away your turns by taking it slow or giving attention to her boobs. You're here to make her cum first, after all, and to do that you have to **** her pussy with all you've got!

You lunge at her, pushing her to her back. As soon as contact is made, your thirty seconds begin.

You use one hand on her tit to pin her to the ground, while you waste no time in darting the other one just over her pussy. Thanks to the rules, she can't resist either one. You're still pretty exhausted from being pushed to your limits during training earlier, but you're fit enough to have recovered at least a little bit.... more than enough to go to town on this pussy!

Delilah looks at you past her flat belly and opens her mouth to say something mean as your fingers make precise and energetic contact with her panties, shutting her mouth again instantly and making her eyes bulge just a little bit for a second. You might not exactly be a scholar when it comes to techniques for making somebody cum, but you can figure the important parts out with just your intuition, and you make up for the rest in heart!

Your hand flies as fast as your aching-but-recovering arm muscles can make it, keeping up a constant pressure as you trace her pussy's lips, press the fabric against her wet slit while running your finger up and down, and tracing delicate little circles around her gash and over the top of her clit. Delilah once again opens her mouth to insult you, having adjusted to your fingers a bit more now, but her voice still wavers a bit as she speaks.

"Ha, is- is that really...... fuck!"

Yes! That's a clear sign that you're starting to have a real effect on her. That, and the spreading of juice through her black panties as her head drops back to the Gymnasium mat and her back arches her hips off the ground just slightly. You keep building on your work, getting her feeling higher and higher, even making her shiver just a little bit, until.....

"Time." Professor Phoebe says. You retract your hands and Delilah drops flatly onto the ground again with a gasp, beads of sweat adorning her tight body and forehead.

It takes a second for her to recover enough to sit up again, but when she does, she gets a sight of your confidently beaming face. After all, that was a total success of a turn, wasn't it? You're beating Delilah at her own game right now. Still, she doesn't seem to be pleased by your confident expression even one bit, which is never a good sign with Delilah....
