The first to fall

You and the other men are brought to the center of the room and made to crouch over the naked Martians on the dais. The Martians' cocks stand proud and erect, glistening with anticipation. You can't help but notice how large they are and wonder how and human woman could take them.

To your surprise, the Martians make no move to fuck you. They merely **** you all to maintain this position, humiliated and exposed. Yet, despite the indignity of it all, something is happening to you. As you hold your position, a strange stir of something akin to arousal builds within you. It's different than usual, an urge to be fucked instead of the desire to do the fucking.

The feeling confuses you, but it's definitely there - an insistent pulsing at your core. It builds quickly, and you realize with a jolt that your cock is starting to throb, almost as if it wants to rise, but seems to recoil in fear.

"Feeling the need already?" Alpha asks with a cruel smile, "Such is the power of our masculinity. Which of you will be first to be transformed? It's inevitable. You are nothing more than a worthless cunt, breeding meat, here to learn its place is wrapped around our cocks."

The three of you groan with need as your arousal builds. You can feel that you're not the only one affected by the Martians' power. Chad is grunting softly, his muscular frame shaking slightly as he fights against the building urges. Mark, too, is trembling, his breath quickening as he fights to resist.

But the pressure is too much, and Mark finally shudders. He makes a low, **** sound and pushes down, onto the thick, waiting cock below him. To your shock, Mark's taint stretches around the relentless invader. The Martian's cock slowly slides inside Mark. Mark looks horrified as his eyes widen at the unexpected sensation. You can see his cock starting to recoil inside him, as if retreating from the invading shaft. The Martian's cock continues its slow, inexorable slide, and you notice with a mixture of horror and fascination as plump, soft labia form around the invading shaft.

"No... no, this can't be happening," Mark cries, but he cannot stop the process now. He continues to press down on the cock inside him, and you can see the massive shaft pushing out his stomach. Mark looks down in time to see plump labia appear around the Martian shaft, clinging tightly as it slides ever deeper inside him. "I... I can't... what the fuck is going on?

The Martian grins, "Your body is adapting, becoming the slut you were meant to be. Your cunt has grown in and soon the rest of your body will follow. Proof that I am the best at bitching and breeding!"
