Michael goes over to one shelf and opens up a case. Inside are several phials, each containing an orange liquid roughly the colour of Tang. "This is the raw stuff. Normally when our researchers ... have an accident, it's because they've inhaled a couple of spores despite wearing protective masks." He holds out the phial, then pulls it back as you reach for it. "If you down the whole thing, I honestly don't know what would happen to you. Probably anaphylaxis. At any rate, it'd be painful."

"How much?" you ask.

He holds the phial up to the light, examining the markings on its side. "A small mouthful should be more than sufficient." He tips the glass tube to his lips and swallows some before passing it to you. You copy him and pass it on to Christina. The solution tastes bitter, and you nearly gag despite swallowing such a tiny amount. You hope its effects are a lot more pleasant.

Michael has crossed the room to the condom case. He feels along the top for a catch, and the case springs open--no glass-breaking required, apparently--to give access to its contents. He selects a somewhat optimistically-sized condom.

Christina says, "When is this going to--ohh." She cuts herself off and reaches down to her pussy, quickly ditching her sarong and bikini bottoms as if they were burning her. "Ohh, that feels so ... good."

You haven't felt anything yet and just content yourself with watching Christina surrender to it. You walk over and help her take off her bikini top, tossing it to the floor with the rest of her clothes, then start running your hands over her body. She moans and says, "Don't stop."

Michael joins the two of you, his cock hard and growing harder. He helps you out of your clothes, and as his hands brush against your skin, you feel the first stirrings of enhanced arousal. He presses his dick between your cushy ass cheeks and rubs it back and forth for a bit.

Meanwhile Christina has turned round so that you can kiss and fondle each other more easily. Michael interrupts this. "Put the condom on me quickly so I can fuck you," he demands, his voice suddenly laced with more authority than you thought he could muster. You turn and meet his eyes, then you glance down and see why.

His cock was seven or eight inches the last time you had seen it erect. Now it was more like ten, and it had grown thicker too. The veins along the side were more pronounced, the head more like something chiseled from marble than an ordinary male glans. You gasp with both surprise and desire and instinctually reach out to grasp it in one hand. Trembling, your other hand accepts the condom package from Michael. You rip it open and gentle put it on.

Your arousal has been building, from a slow, throbbing horniness to a more insistent, demanding, animalistic urge to fuck. Just as Michael's cock has grown, your own tits and cunt have swollen slightly from exposure to the pollen. Your nipples are bigger than you've ever seen them and stick straight out, rock hard, every centimetre of your breasts just as sensitive and begging to be touched. Your cunt is on fire, warm and wet, your labia redder, thicker, slicker than you've ever imagined they could become. Next to you, Christina's heavy breathing confirms she is in an identical state of readiness.

Never in your life have you felt such powerful arousal, and as you stand before Michael's erect member, you have no compunctions about what happens next.
