Of course not!

The trip couldn't go by fast enough. The truck was at a stoplight a few blocks away from the clinic. Your leg kept bouncing in frustration, glaring intently at the red light. C'mon, c'mon! you growl to yourself. Is this the longest stoplight in the world or something?!

Alex looks a bit unnerved at your behavior, but right now you don't really care. All you can really think about is the aching need between your thighs that is driving you insane. It's kind of similar to how being horny was like as a guy, but worse. A good way to describe it would be that it's like how you feel sitting in the passenger seat of this truck right now. You really, really want to get to your destination (getting laid), but you have to rely on someone else (Alex) to get you there (putting his dick in you), which isn't happening as quickly as you want. Your thoughts keep flicking from Alex in the seat next to you, to the toy in the duffel behind you, back to the light which is still fucking red!

The light turns green and you let out a breath of relief...until the next stoplight turns red.

"Fuck!"

Finally you arrive at the clinic. You don't even bother letting Alex park, you just make him drop you off at the front doors. You quickly march up to the front desk and ask for the clinical trial. The receptionist eyes you for a moment before handing you a clipboard with a slight smirk on her face. Scowling at her, you snatch it from her hands and look it over. The first page on the clipboard is basic medical data, the second is an agreement that you would get paid after you return for a followup, and then the next few pages are **** information sheets and waivers of responsibility.

You don't know your new height or weight, let alone where you are on your menstrual cycle, so you just make up a bunch of information and sign the rest of the documents without even glancing at them. You give the clipboard back to her and are escorted to an exam room.

You figured that you were going to have to be waiting for an hour, but surprisingly you've barely sat down before there's a knock on the door. In walks a middle-aged doctor and a female nurse, pushing a little cart. The doctor smiles at you genially.

"Good afternoon, Miss Doe. How are you today?"

"I'm alright doc. Can we just get this over with? I'm in a bit of a hurry." You start rolling up your sleeve.

The doctor's eyebrows shoot up at your tone. "If you insist. However, we don't need your arm. The medicine is administered vaginally."

A ice cold feeling shoots through you. A needle in your arm you could take. A needle up your cooch? "You've got to give me a shot where?!"

The doctor lets out a soft sigh. "You did actually read the application before you signed it, correct?"

"Of course I did!"

The doctor sees through your bluff and shakes his head. "Well Miss Doe, then you should know that the **** trial is not a shot but a cream. If you would," he gestures towards your legs.

Now that you aren't faced with the prospect of having a needle shoved inside you, you quickly strip off your lower half. Thankfully the two are medical professionals and don't comment on how you are practically dripping wet, though you do notice that the nurse places what looks like a bottle of lubricant back down on the cart. You sit on the edge of the hospital bed and spread your legs, resting your ankles in a pair of stirrups. You didn't even take your underwear off completely, so they hang from your ankle like a white flag of surrender.

The doctor picks up what looks like a very long tampon and steps forward between your thighs. The sight of a man looming over you, standing between your open thighs, preparing to shove a phallic object inside you sends an electric thrill through you. Your head starts to go fuzzy and you feel your vagina quiver. You vaguely realize that he is talking as he places the applicator slowly inside you until it thumps into the back of your vagina. He presses down on the plunger and you feel a vague sensation of cold bloom somewhere around your belly button.

You are too distracted to pick up on exactly what he is saying--something about how the medicine messes with the cervical mucous, turning it into a natural spermicide--as by the time you regain your senses, he's left the room. You are left alone with the nurse, who packs up the cart and starts to head out the door.

Before she leaves, she turns to you with a smirk on her face. "You should wait about ten minutes for the cream to take effect before having sex. Have fun, dear~" With that, she heads out the door.

Your face is red and your breath is shallow. You can't wait any longer.

You roughly pull up your underwear, causing a snapping noise from them as you do, and then your pants, practically stumbling out the door in your haste. Either Alex had some trouble finding a parking spot or the visit was over quicker than you thought, because he is just coming through the automatic doors when you get back to the lobby. You don't even break stride, hooking his elbow as you pass by him and practically growl at him to get you back to his place.
