Not much at all!

The heat in your chest builds up -- and then slowly shrinks away and vanishes. Delilah continues to squeeze and **** your breasts through your shirt material, but you're not feeling anything more than a bit good and sort of embarrassed. But that means you have more time to work on using your fingers that are down her pants, which you do!

"Those idiots told me they'd gotten you!" Delilah screams angrily, squeezing your breasts as hard as her hands will let her in an attempt to..... do something, youunno. But it seems to really make her mad, as she keep working up and down your breasts and squeezing them tightly as you run your fingers around and through her lower lips. You can feel her heartbeat through her boobs, pressed up against your back, and it's getting faster and faster as her gripping hands get weaker and weaker and there's a faint jiggle in her legs.

"I- I'm still your superior!! I'm better than you, you know!" Delilah shouts out at you accusingly, kneeding your fruit fruitlessly. It's difficult to believe her though, as her grabbiness gets even weaker and she starts folding under your touch. She's leaning more heavily on you than before now, which you take as a sign that her legs are giving out. So don't stop now!

You've managed to dig and wiggle your index and middle fingers to actually be inside of her, and you retract and extend them to keep probing her depths. At the same time, you rub your hand up and down, to give you all sorts of new and different angles at her insides while your ring and pinky fingers' knuckles rub up against her sensitive spot at the top of her opening. She's soaking wet, and basically crumbling as you work even harder on her. She refuses to give up with whatever she's trying to do with your boobs, but that's alright to you even though it's embarrassing. You're winning this handily!

All of a sudden, her squeezing and rubbing stops. Her hands freeze, palms held against the tips of your domes, pulling herself tightly into your back. Her cushions are really pressed up against you now, and her legs are shaking and occasionally kicking as you keep using your hand to work her through it. It's working!

"N-no, w-wait.... h-howww....w......???" Her voice trails off to nothing in disbelief, as your fingers work through her folds and slowly drive her mind out of her weakening body. You're not sure why she hedged her bets so much to let you get this far ahead, but you'll take it! You can feel that you've got her right on the edge, so you just need to push her over!

Her chin comes down to rest on your shoulder, as she hunches the pair of you forward. You turn, surprised, to take a look at her face -- both eyes are closed, and her lips and held tightly together as she moans and wiggles around in your grip. She's not saying anything or looking at anything, and both of her hands are still clasped to the front of your shirt, but still -- maybe you can use this? Yeah, for sure, you have an idea!

Still working her over with the one hand, as her knees at last give out and bent limply inwards (the rest of her weight going right down to your hips as she leans over you), you reach up with your other hand towards her face. You're not sure..... but you think...... you heard one time...... there, that's done it!

You **** your thumb up through her lips, and her eyes shoot open wide in surprise. Then, as you wiggle your thumb around inside her mouth in what could be called dominance, her eyelids flutter and fall limply back to a narrower position. She gently moans once through her otherwise-closed lips, and then gives in, and starts to suckle on the edge of your thumb.....

And that's it! The stimulation to her lips and mouth brought her focus away from her bottom half, so now you're free to go on her folds full power, rubbing with as much **** and speed as you can muster, to push her tumbling over the edge! Her lips clamp down around your thumb and her eyes squeeze tightly closed once again as her pussy gives in to your working hand. Her dangling legs lock up, and her walls close tightly around your invading fingers, as she squeaks at a barely-audible volume and cums all over your hand and the inside of her panties.

Hey, hey -- you did it! You actually.... wow, that's so cool.

Her arms go limp, and her hands slowly drag across the front of your shirt-boobs before falling down by her sides. Now with dangling arms, and legs losing power once again, she's just leaning orgasmically against your back with her face turned sideways and cheek resting on your shoulder. You take your hands away and step forward, sending her tumbling down to the ground in a slumped position. You wait for a couple of seconds, and she's definitely still awake, but she doesn't get up..... does that mean it's over?

"noooooo......" Her voice weakly moans out as her forehead sits still against the bathroom tile, as if you weren't even in the room. "n-not to me-e......... n-neeverr, never to me......"

.......That sounds like a victory to you!

Quickly washing your hand off at the nearby sinks, you then break out into a HUGE dance celebration as you stand there in the bathrooms, having a miniature private rave at the fact that you just jizzed her with your hand, on her own terms. Nice work!
