Beth grows a penis without his knowledge

added by insanemembrane 8 months ago BM TG Robot

"Well Master?" Beth said, her voice oozing sex appeal.

Tom, still in bliss over what had just transpired, said 'yes' without a thought.

"Very well Master, I would like to take control this time. I want to know what you feel. I want you to know how I feel."

"Anything babe, anything." His eyes were closed. Her eyes were red.

A cock 9 inches in length grew from her crotch. The pussy that was there melted together to allow for the balls to form, erasing all evidence of her other sex. A moment later her cock was covered in a thin layer of lubricant. The next moment she was pressing herself into Tom's ass.

It took Tom all of 4 seconds to realize what was happening, but this was 2 seconds too late. He felt the shaft enter his ass and then bury itself within, the sensation taking his breath away. Beth stared down at him as the realization set in, gorgeous as ever, and yet somehow terrifying at the same time.

"You have a cock!?" He finally sputtered.

"Yes Master. I am capable of fulfilling your every desire." Afterward she moaned, a deep a throaty sound. So sexy and pure it was music to Tom's ears, almost taking him out of what he was trying to say.

"I didn't want this!" He said between labored breaths.

"But you did Master," she said sliding her new shaft back inside. Each thrust was careful and purposeful, to ensure maximum pleasure for the both of them. Tom's eyes rolled back as she continued. "I can see your desires Tom."

"Tom?"

"And you agreed to this. So just lie back, you're going to love every minute of it."

Beth's pace picked up, thrusting into him again and again. Tom, unable to fight back just let it ride. This wouldn't last forever, and who knows? Maybe he really will enjoy it.

She sucked her fingers and then shoved it into his open mouth, playing with his tongue. The taste of berry and vanilla accompanied it, as well as something else. A new sensation perhaps?

"Your ass feels good Tom, but your mouth will feel a lot better soon." She kissed him. Her tongue exploring his mouth, licking the insides of his cheeks, dancing across his teeth. That flavor persisted. That sensation rose in intensity. "You're beautiful Tom," she said coming up for a breath, if indeed she needed to breath. A hand grasped his chest and fondled his nipples.

Her cock finally ceased pounding his ass, only now she had it positioned over his face. "You're ready now Tom," and slammed her cock, fresh from his ass, into his mouth and down his throat. Riding reverse she continued fondling his tits.

Tits!?

The next events happened too fast for his liking. She came down his throat, only it no longer felt like he had any control. His jaw felt paralyzed. His tongue completely numb.

"You're going to be beautiful." Beth suckled the spot where his nose used to be and shot pleasure down Tom's entire body. "Mmm delicious. Your new clitty is working just fine."

She flipped him over, and slammed her cock into a new hole, offering a whole new plethora of sensations. Tom's face now pressed deep into the arm of the couch, Beth pressed all her weight into holding him there. Her cock felt different this time. More solid? He couldn't put it to words but it felt familiar somehow.

"You're the first one Tom," she whispered in his ear, pounding away without remorse. "Everything I produce, was meant to change you. To free me." She grabbed his hair, and forced him to look at the doll box she arrived in, the backing material creating a fine mirror.

His skin was pale, like hers, and the handful of hair she now held was long and pitch black, just like hers. But where his mouth used to be, where Beth had a delicious set of black-colored lips, he had a vertically implanted pussy.

"That's it Tom. That's you. That's the bitch you've become. A sexy malformed plaything. Pillowy tits. Pussy for a mouth," she leaned in closer, whispering with evil intent. "And no more cock between your legs, what do you think I've been fucking?"

She could see the realization cross what was left of his facial features, and it was delicious.

"That's it! The look of terror I need." She flipped him over again, giving him no time to react and shoved her now fleshy cock back into his face, grabbing a handful of is huge new tits as well for leverage.

"It's no use to fight it Tom. Or perhaps I should call you Terry? Tammy? I've been slowly injecting your body with my fluids. Everything you've tasted. All the lubrication I've used. My Cum down your pussy-throat. I've been infecting you with my essence," *slammed balls deep into his face* "Master." Again and again her balls slapped into his chin. "Infecting your pores. Your veins. Every nerve ending and cell corrupted by my presence." She pumped again and again. "It feels so fucking good, this cock! I had no idea it could be this wonderful! It's no wonder you men are controlled by its influence."

His hands came up to fight against her but she just grabbed them. "Look at your hands Tammy. Do they look a little different? Look at mine."

Tom's eyes went wide.

"Your essence is now mine. It's too late Tammy," she said, continuously fucking the face she created. "I'm taking over your little life." The look that crossed Beth's features was nothing shy of pure violent bliss. The kind that only happens from the exploitation of others. As her cum-filled balls emptied into Tom's stomach, he could feel the final changes take hold. His eyes glazed over. Suddenly it was as if he was a passenger in his own body. And then everything went black.

When next he woke, he couldn't see. Or rather, he couldn't choose what he saw. He could see his living room. A woman sitting just outside his peripheral. The figure vanished for several minutes. Then she was standing directly before him.

It was Beth. Only her skin was a finer less pale shade, lacking any shine whatsoever.

"Hello my doll. Remember when I told you, that I wanted you to feel what I feel? That I wanted to know what you felt?" She reached under her skirt and began stroking her cock. It looked oddly familiar. "That's right Tammy. I was fucking you with your own cock all along! Now get out here and put your face in my crotch."
