The alarm blares

As Kim looked up at the blackboard covered in diagrams of ideal positions for subduing invaders, she looked out onto the school courtyard. It was in a word, massive. It had to be, as it acted as the battleground whenever the invaders attacked. It had been a few days, Kim thought. "I wonder when the next attac--"

"VWAAAOOW, VWOOOAW, ATTACK FORCE DETECTED"

The schools early warning alarm system answered her question. The class had been through enough of these attacks by now to be able to react instantly to the alarm, and the class scrambled out of their chairs and ran out into the hallway, their teacher running ahead of them towards the launchers. The launchers were essentially springboard that flung the students out into the courtyard. They were quicker then having to run down the flights of stairs and through the main doors. As she neared the springboard, Kim looked to her left and saw Jack with a grin on his face, which wasn't all to unusual, most got some enjoyment out of 'combat', Kim sure did. She disregarded this thought however, and barreled ahead to the launcher, and launched herself outside into the courtyard.

Kim flew through the air, and soon landed on her feet outside, surrounded by other students, and about 1000 metres in front, were the invaders.

The invaders, despite their varying body types, had the same basic appearance. Jet black, rubber-like skin, what seemed to be toned muscles, but their faces were what stood out the most. They were human like, but despite having the shape of eye sockets, they had no eyes, and despite having the shape of a nose, they had no nostrils. They did however, have mouths, which weren't normally visible, but could be seen contorted into a grin while they were fucking. The only part of them that wasn't black was their hands, which seemed to be covered in gloves. They also seemed to be wearing shoes, though whether or not they had a point, Kim didn't know.

Soon after Kim had landed, a shrill whistle sounded out, and the voice of the schools headmaster reverberated around the courtyard.

"Students, ATTACK!"

Kim, alongside her fellow class mates, charged forward, as did the enemy. Soon they had meet in a clash, and the wet sounds of defence were sounding around the courtyard. The student goal was simple, make the enemy come three times before you cum three times. Kim had ran ahead and reached a drone with a 12 inch cock. 'This should be easy" she thought, a small grin on her face, as she slid onto her knees and took the cock into her mouth and began to suck. Soon the drone had shot two loads of sweet, sticky, thick cum down Kim's throat, and was clearly nearing its limit

"GLK, GLK, GLUK, GLK, GL-"

The drone unleashed its final load down her throat, and it fell backwards, its (admittedly yummy) cock sliding out of Kim's mouth in the process.

"EZ" Kim said, wiping some drool and cum that had accumulated on her chin. "Which one of you punks is ne-aaaahhhHHH" She was cut of as a drone had managed to sneak up behind her and pulled her into a standing full Nelson, and had thrust its 20 inch long , 4 inch girth, into her drenched pussy.

"Ah, Ah. Ah, Uh, Uh, Uh". The moans emanating from Kim, caused by the electric sensation in her elastic pussy, join the chorus of moans of the others. Thanks to being impaled on this cock high up, Kim could see most of the battlefield. She saw Hannah, two giants holding her suspended in the air, as they alternated thrusts in her ass and pussy. Amy was the ground, her ass being pounded into by a drone, and Jessica had two drones cocks between her tits, and a hand on either side, moving her breasts up and down with an impressive speed.

The guys seemed to be faring better. Daniel was being ridden by a domme, but it seemed he was able to hang on and not bust a nut just yet. Mark has two female drones, one lying on top of the other, and was thrusting into both of their pussies at the same time, and Jack had a butt-slut and a two drones, and while he was thrusting into her butt-sluts ass, he was fingerings the drones, occasionally removing his fingers for a second to slap the butt-sluts ass, the returning to fingering.

Kim also saw a few of her classmates in various positions. one classmate had been pushed to the ground and was on her hands and knees, while the small goblin types fucked her ass, face and pussy. Another particularly buxom babe was sitting of the face of one of the drones, while taking a giants cock into her mouth, and judging by the sounds she made, she was doing so effortlessly.

During all if this, Kim had been jackhammered into by a cock and she had cum twice, and the drone had only pumped in one thick load, and soon Kim was convulsing, her third orgasm coursing through her. Intelligent thought seemed to leave her head, as the drone dropped her on the ground, and all she could do was giggle and say "cock".

Some time later Kim came to in her bed, and looking at the clock, it was about 2PM and she'd been out for a while. It was a little embarrassing having been taken out by a sneak attack, but it happens, so no biggie. The school was still standing, so they had obviously won. Kim straightened her tie, which was draped over her sloshing breasts, and made her way to the cafeteria, where her friends were sure to be eating, the attack having pushed lunch back.

When she arrived she saw her friends sitting at their usual table and joined them. They talked about the battle, and it seemed that both Daniel and Hannah had also been knocked out, so Kim felt a little better about her lackluster performance. However, it was Jack that seemed to be the man of the hour, as he had dispatched more invaders than anyone else and he was starting to gloat.

"Maybe you want a reward" cooed Amy, not wanting her friend to get a big head about all this.

"Wouldn't say no" Jack replied slyly, and the grin in his face widened as Amy moved of the stool she was on and under the table. Jack had done good today, Kim thought

"I'll gave to thank him later" she giggled to herself.
