Helena "helps"

"That's unusual, but promising," Doctor Philovibe mumbled through the speaker. While you can't see him, it sounds as though he's scratching his chin in thought. "Just try to relax, Joy, and explain what you're feeling." In your current condition, his words seem almost laughable.

"It's so hot, so deep!" you whine, struggling to retain some train of thought. The vinyl padding of the table beneath you feels wet, no doubt being soaked by the flood of juices leaking from your needy slit. It doesn't help that your ass is still tightly plugged either, warping your once tight hole around it's unyielding hardness.

The slightest of smirks tilts the corners of Helena's lips, as if the barbaric blonde is actually enjoying the show. Again the speaker crackles, it seems that the Doctor caught that smirk as well. "Very well, Helena, you may continue the experiment." Your eyebrows rise wildly at the order, you weren't warned about this. "Wait, what?"

"HOLD STILL!" The icy amazon booms, a command you're not about to disobey. But you can't help but peek back at your companion, perhaps you'll get a clue what the next phase might be. Much to your surprise, the Doctor's assistant has peeled off her gooey gloves, and is carefully unbuttoning her labcoat. A part of you wants to protest, the stern woman isn't exactly your type.

But regardless of your brain's misgivings, your body is in charge now, and you push your hips back invitingly. It takes some time to go through all of those buttons, but soon enough you understand why her clothes are so concealing. Helena's cleavage far exceeds your own! It must be one of Doctor Philovibe's experiments, but you won't consider that until the fog has lifted from your mind.

Despite their size, there doesn't appear to be the slightest sign of sagging or age, and the plump globes bounce softly with her movements. Without the bulky coat obscuring your view, it's easy to see just how tight the assistant's skirt is, the red leather gripping her hips tightly. Without a word, she circles you, her heels clicking on the tile as Helena takes a stand directly in front of you, bringing her crotch surprisingly close to your face.

More surprising is that you don't mind the proximity, and soon find your mouth watering from the smell of her nether regions being so teasingly near and yet out of reach. "P-please.. I need it.."

Helena nods slowly, reaching down to unzip her skirt before tugging it down her shapely hips. Then comes arguably your biggest surprise of the night, a thick, swollen cock flops free to point menacingly right at your face. Your mouth falls open, an expression of purest shock at the throbbing behemoth. A sizable pair of nuts hangs beneath, completely shaven smooth. Behind them, you can just barely make out the dewy lips of her pussy, it seems that you aren't the only one enjoying this experiment.

"Um," Begins the Doctor, choosing an agonizing time to interrupt, "I did mention the Gender Bender's effects, didn't I?"

"Ja, she is simply in shock," Helena replies, speaking about you as if you're nothing more than a test subject. Which is currently the case. Taking hold of the meaty spear's base, she brings her shaft down on your face three times, watching the fleshy rod bounce off of your cheek.

"Whenever you're ready to begin, and try not to do any lasting damage this time."

Before you can ask what the Doctor meant by that, a firm hand sinks into your hair, forcing your eyes to meet with the hermaphrodite looming over you. "Vell, Joy, it's your choice.."
