Amy

A blinding white light seems to fill your vision, and when you come to, you are standing, unsteadily, with Jeff holding your shoulders. You look around and see your hand holding onto — the penis of your **** body! You have transferred your consciousness into Amy’s body, and your own body is slack and apparently asleep.

“Are you ok?” asks Jeff, looking concerned. “It looked like some of that electricity jumped to you.”

“I’m just a little unsteady,” you say, truthfully. Hearing your words with Amy’s voice adds to the surrealness of it.

“I guess you can stop jacking him off,” says Jeff, pulling Amy’s hand off your now-limp cock. “I’d say you got enough of a sample there to study.”

Jeff is right. You have never shot such a load before. Your semen covers your chest, stomach, and a majority of Amy’s hand — not to mention a fair amount that splattered on the front of her blouse.

Although the condition of your penis suggests that your body’s horniness has subsided, the same cannot he said for Amy’s. In fact, you have never been more sexually aroused, which seems odd, considering you do not presently have a penis.

Jeff continues to look concerned. “Maybe we should call Dr. Burbank,” he says. “You don’t look well.”

Thinking fast, you grab Jeff’s arm before he can reach for his phone. “It’s not that, Jeff,” you say, bringing your body close to his. You can’t believe how natural — or how good — this feels to you! “I just couldn’t stop thinking about you while I was stroking his cock. All I could think about is how much I want yours, instead.”

You lean into him and kiss him deeply, while reaching down and grabbing his crotch. After a brief moment’s surprise, Jeff’s mouth and cock respond. You feel his strong arms wrap around you and his body press hard against yours.

Soon, the two of you are on the laboratory floor, hands exploring all over each other’s body. Jeff feels so good — muscular, well defined, and hard all over. You suck on his tongue and feel him tremble as you begin to undo his belt.

Jeff’s hands unbutton the front of your blouse and slide it off your shoulders. You feel one of his hands on your breast as the other hand moves behind you, unfastening your bra. It’s a good thing Jeff knows how to do that, because if it were left to you, it might take half an hour to figure it out.

You feel the bra release, and you look down and get your closest look at a woman’s breasts. You see them only a moment before Jeff’s head obstructs the view. He nibbles, sucks and gently bites at your nipples as you begin to rock back and forth over his hips, rubbing his and your still-clothed crotches together.

You pull up his shirt and help him pull it over his shoulders. You look at his muscular chest and feel a fire within you start to burn. You lower your head to his chest and flick his nipples with your tongue, causing him to moan.

With his hands in your hair, you feel Jeff guiding you downward. You kiss his stomach and rub your face against the bulge in his pants. Then, using your teeth, you pull down his zipper, unfasten the top, and pull his pants and underwear down and off.

Jeff’s cock springs free, and you take it at once and run your thumb around its tip. His cock is bigger than yours, and it suits his handsome form. You kiss the tip tenderly, resisting his attempts to push your head down on it.

“Don’t tease me like that,” he pleads, and you realize how fun it is to have this kind of power over another person.

Extending your tongue, you begin to quickly lick the tip of his shaft, feeling him squirm in anticipation and pleasure. Finally, unable to resist it yourself, you open your mouth and take his whole cock in your mouth. It fills you, and you feel it hit the back of your throat. Resisting the reflex to gag, you let it go further into your throat until your nose is buried in his public hair. Jeff lets out a gasp and looks down at you in wonder.

“That’s fucking amazing!” he says. “When did you learn to do that?”

You grin and slide up his body, until you are looking down on his face. You feel his hard cock pressing against you, and you reach down, grab it, and position it at the entrance to your pussy.

“I’ll tell you where I learned it after you fuck the shit out of me,” you growl, and you lower your pussy forcibly on Jeff’s hard shaft.

The feeling that comes over you is beyond belief! You feel every inch of his rigid cock, and you feel full and stretched and wanting even more, all at the same time.

Jeff has no words for you, but he grabs your ass with both hands and guides you up and down on his piston-like shaft as it drills you in and out, repeatedly.

How long this goes on, you have no idea, but right as Jeff gasps, “I’m cumming!” and you feel his seed erupt inside you, you also feel a powerful **** building between your legs, growing ever more powerful. You feel your muscles clamp hard around Jeff’s cock, milking it for everything you are worth, and then the biggest wave of pleasure you have ever known sweeps over you, causing you to collapse on Jeff’s heaving chest.

After a few minutes of panting, Jeff says, “What the fuck came over you?”

You sit up, his shrinking cock still inside you, and smile.
