Race derailed

"Fuck that! Change me back you bastard!" a male racer yells. You grimace. This idiot has no idea how unlikely it is anyone will escape with their freedom, much less their cocks. The Martians stopped attacking years ago, but now they play these 'pranks'. Not much of a prank when pretty much every victim ends up a female breeder stuffed full of Martian dick, regardless of their original gender. Sometimes they'll let a few go, but the vast majority they take back with them to pop out more babies.

The Martian announcer merely laughs and steps forward. In a swift motion, he picks up the man by his waist and plunges his new pussy down on the Martian's cock. The man's face contorts humiliation as his struggles against the ****. His clothing starts to tear as his hips widen, and new breasts swell on his chest, almost bursting from his shirt. As the Martian continues to fuck him, you can see the man's expression change. Where there was horror and pain, there is now a blissful look of pleasure, his body incapacitated by the overwhelming pleasure Martians use to control their victims.

Seeing the female races squirm on their dildos as they watch the show, you're reminded that women find it even harder to resist the Martians. Unfortunately, that means the Martian pranks are focused on men since the Martians enjoy watching their initial resistance be replaced by wanton need as their bodies and minds are remade. You watch in despair as the man transforms before your eyes, knowing you will very likely soon have be in his position. His voice becomes higher pitched and his body grows softer as he begs for more. You feel yourself getting turned on as well. You start to breathe heavier as your new pussy drips with need.

"Come on guys, let's finish this race," one of the racers says, trying to ignore the erotic display. But it's no use; all of the races are affected by the sight, making it difficult to focus on anything but the heat between their legs. All of you are now squirming on your dildos, moaning as you explore the new sensations available to you. The Martians know exactly what they're doing, using their pheromones and displays of dominance to make sure every human succumbs to their desires.

Finally, the Martian announcer cums inside the transformed man, causing her to let a blissful moan as she shudders in ecstasy. With a grunt, the Martian drops the former man to the ground, still quivering from her intense orgasm. Seeing this, the other Martians grow impatient. They start grabbing other racers, pulling them off their bikes and stuffing their pussies with their cocks. Everyone is being transformed, and there's nothing any of you can do about it.

Your body feels like it's on fire as you're grabbed by one of the Martians. Your mind is clouded with lust, and you're unable to put up any resistance as he lowers you onto his dick. As he bottoms out inside of your snatch, you feel yourself growing softer, your muscles fading as new breasts began to form on your chest. Your voice becomes higher-pitched and feminine, and you can't help but moan as the Martian continues to fuck you.

Around you, the other races are being similarly transformed, their bodies changing to suit the Martians' desires. It's a terrifying sight, but your own body is too busy responding to the pleasure to care about anything else. As your transformation reaches its peak, you find yourself crying out for more as your hips widen and your breasts continue to grow. You can feel your insides stretching and adjusting to accommodate the Martian's cock, and there's no denying that part of you is enjoying every moment of it.

Finally, the Martians cum inside you, filling your newly formed womb with their seed. The feel of his cum splashing against your walls sends you into another trembling climax. The Martian holds you to his chest as he turns to leave, still impaled on his cock and bouncing on it with his steps. You are naught but a cockwarmer for him. Something to amuse himself with until he tires and throws you to the breeding pits.
