Surprise!

It was blink-and-you-miss-it, and indeed I made nothing of it in the moment, but Lenina had a peculiarly normal reaction to my sudden move on her. She yelped, and instinctively shuffled backwards, only halted by the edge of the classroom doorway. Her hands flew to my shoulders as if to violently shove me back. She aborted the motion, but the sheer power and momentum in her part Terran muslces and bones was simply too much for my body to handle. Neither of us lost balance, but only because she immediately redirected her energy in favour of the embrace, singlehandedly stabilizing us. There was not an instant for me to ponder her split-second change of heart, as she returned the kiss vigorously.

During the next twenty odd minutes that we were alone together, this pale, slight-looking girl used her brutal strength readily and without prejudice. She dragged me into the empty room and kicked the door shut. Effortlessly she flicked my fly open and dropped my trousers, before properly shoving me backwards onto the nearest table. The next thing I knew my dick was in her mouth and rapidly swelling with each second.

Looking back I can see how she blatantly changed her tune. There was no pussy being used as property in this situation, unless you consider me one. While I will freely admit that I am far from a brave soul, I think not my actions cowardly - so far. No, I was simply not rational. The kiss had confirmed my impression of immunity to the psychedelics, because once again I sensed its presence in Lenina’s mouth but did not feel a drastic shift in my inclinations. When I was tripping into the empty classroom after her, I was still aware of my identity, and in a hurry to get this over as quickly as possible, but also now a little less paranoid about to the preservation of my free will. I wasn’t holding myself on my toes quite as hard. I thought my partner must be bored of roleplaying, and if it meant she relieved herself of her desires toward me faster, so much the better.

Lenina practically jumped on the table, barely restraining herself enough to avoid damaging it or me, and climbed to straddle my waist. She lined herself up with my cock and dropped straight down, not even waiting to start milking it, bucking her hips first, then squatting up and down. Right from the start she went hard enough for her butt cheeks to slap audibly on my thighs with each impact. Inside she was already very wet, and juice glistened on my cock after the first penetration.

“Fuck yes,” she exclaimed, tipping her head back, “Can’t wait to drain that thing. No way is one girl getting you all to herself.”

Her pussy felt tighter than anything I’d ever felt before, as if she could squeeze my cock way more than any other girl. Of course, I may have just been biased to perceive her that way, half-blood powerhouse that she ostensibly was. The sight of her was equally extraordinary in this position. Perfectly centred on her lively bouncing breasts, the nipples contrasted well against her unusually light pink skin.

As I wasn’t wise yet to the shift in tone, Lenina had to explicitly draw my attention to it, although I still failed to see it for what it was. She reached down and took my hands, placing them on her chest. “How do you like my little role reversal?” she said, as I obediently started playing with her tits. “I though it was appropriate since technically it was me pursuing you. I’m fucking you now.”

“Love it.”

"Good. By the time I'm done you'll be dry as sand."

Still riding me faster and faster, she got busy with herself, fingers blurring over her clit. She leaned forward, letting her weight crush her breasts into my palms. Her eyes rolled back, and her head followed the motion. Vibrations in her chest grew until she growled her pleasure at the ceiling.

Suddenly the grip of her other hand on my arm tightened to a painful pressure. I tought my wrist would snap. But in the same moment her sopping wet cunt contracted violently on my dick sending me into a confused funk of ecstasy and pain. When the fog lifted and I found both my afflicted limbs intact she was already done climaxing, and had moved on. She jumped off the table and landed in a superhero crouch, straightened up and immediately shoved my cock back into her mouth. Her timing was flawless. In reaching her orgasm, she'd driven me to the edge, and within seconds my balls twitched and the first rope of cum surged upwards.

"Thank you for your cooperation, Mr Oliver. Your semen will be invaluable to us. Or to me specifically. For sure I'm getting promoted out of this job. I don't even like men let alone you fucking weaklings. My gran could probably kick your arse..."

There was no need to understand what she was saying, and at first, I didn't. All the horrible meaning was in her voice, and after I jumped to a sitting position with my eyes open, was plainly visible on her countenance. She was smiling to herself, and casually sealing shut a small clear vial of liquid, a sample of me.

"Don't gawp like that," she told me after stowing the capsule, "Your lower fangs are crooked. Not flattering."

"What happens now?"

"To you?" Lenina shrugged. "That rather depends on a couple of things. If you just got lucky then I expect they'll inject you and send you home. If you relapse because you're actually immune on some level, that's where it gets iffy. I would hope in your shoes that this sample rapidly produces a better and more potent serum, because the Tantalus Machine does not sound fun. I hear they already used it once and the results are quite drastic. Horrifying from your perspective."

"So there really is an organized **** controlling this?"

"Yup."

"Okay, so what if I kill you and run away?"

She grinned at me, but took a step back. Her hand flashd to a trouser pocket and came up holding a small black object. She pointed it at me, one thumb hovering above a button in the middle. "The first slight problem with your proposition," she said, still smiling, "Is my brawling advantage. Like I said, my grandmother could probably knock you into the ground with ease. However, if you just so happened to be trained in martial arts and also more skilled than I am strong, then..."

Behind her, the classroom door was making strange noises. Somebody on the other side was trying to open it. They must have assumed it was locked, accidentally locked it, and now had to unlock it.

"Shit," Lenina muttered, and the weapon vanished back inside her trousers just as the door swung open, revealing none other than:

"Carmencita!" I exclaimed, "What a pleasant surprise!"
