Actions speak louder than words

It doesn't take long for that overwhelming urgency to whittle away at your sudden surprise. You barely even register what Helena just said, or even that it was a question. The towering blonde's eyes blare down coldly, shining true with all of the intelligence and danger of a predatory beast sizing up her prey. It sends a shiver of something down your spine, but it's impossible to tell fear from anticipation at this point.

Without a single word of warning, your mouth opens wide, engulfing the swollen head of her stiff fuckstick in one hungry movement. Even the taste is amazing, as if the fleshy organ is somehow sweeter and less musky than a man's tool. A deep groan of approval meets your efforts, and you feel an odd swell of pride at her appreciation. Of course, her fingers remain knitted in your golden locks, and she uses that to her advantage, pulling your lips further down that vein riddled slab of pink muscle.

"Ja, get it nice and wet, slut." While her order is delivered with that trademark sternness, for just a second, Helena almost sounded pleased. Perhaps that's what the stony blonde's problem is, she just needs to bust a nut! A sickening slurp echoes through the observation room as you double your efforts, sealing your lips as firmly around that mutant member as you can manage.

Of course, your own need for release weighs heavily as well. Your right hand soon begins to slither southwards, leaving you perched on only three hands. But Helena's not having it. Another tug of your hair, sharper this time, not only causing you to wince, but almost gagging you on her swollen spear. "Not yet," the assistant growls down menacingly. You whimper up desperately, but the only response is a lifted brow. It's agonizing, your clit practically throbbing with need while a river of womanly juices trickles down your thighs. surprisingly, that doesn't halt your suction, instead you simply slurp harder, as if the only outlet for your lust is Helena's cock.

"H-helena, I must advise you be gentle with our guest," the Doctor chimes in once more.

"She von't complain, this vone likes it," she purred coolly back.

Of course, your own opinion wasn't asked, as your lips are currently straining around a fat hunk of meat.

"Well of course not, the formula's seen to that. But if my calculations are correct, you should save as much sperm as possible for phase two."

Helena's brow furrows slightly at the remark. "I think I know how to handle- UGNH!"

That sudden grunt was your doing, just hearing the word sperm was enough to spur you onward. You need this cock inside of you already, even if you have to guzzle down every drop of cum to achieve your own climax. Helena tries valiantly to pull you back, but it's now a matter of an irresistible **** against an immovable object. The disciplined genius, or a wanton slut?
