They take it out!

You feel them grab the dildo. The pulling sensation in your anus is almost indescribable; holy shit does it feel fucking great! Their other hand is pushed against your back as leverage, as they continue to pull it out, inch by inch. Each little bump that stimulates your prostate makes you squeal in delight like a little pig. It causes your cock to tense and stretch, painfully pushing against the bench. You know you should try to escape before it's too late, but you're trapped here more by your own pleasure rather than his will.

Then, when there was just an inch or two left inside, they gave it a final almighty pull, and yanked it out of your anus. You can't stop yourself from orgasming, splattering your cum against the bench and your belly. You moan loudly. Your cum drips between the gaps and pools on the tiled floor. Your arsehole is gaping, though you can feel the tightening sensation closing in. But they don't let you pucker up. They push their cock in with ease, their size not nearly as big as the dildo, though they were still large all things considered. It felt better than before, even if you're looser now; their cock is warm and rigid, and pulsed more naturally. They growl, letting their drool fall on your spine. You struggle a little, trying to shit out their cock, but you are just too tired and relaxed from your intense orgasm. There's not much you can do but let him have his way with you, and you know that spells the end. It's probably too late to do anything either way.

He thrusts his hips, squeezing your buttcheeks together with his hands. You would be lying if you said it didn't feel good, but he was rough, and you could feel your anus be broken in. But even the pain slowly began to feel good, as if your opinions and thoughts and sensations were changing rapidly. Your body was changing rapidly. It was difficult to describe. It was just...

"...soooo... ghoooood..."

You couldn't help yourself. You groaned, your voice now raspy and coarse. There was no doubt about it. You might still have a minute of free will, but there was no way of avoiding it now; you are one of them now. A zombie, an infected... it feels amazing! Ungodly heat spreads through your veins, working from your legs, up to the tips of your arms, deep into your chest, and then to your head. Gentle, loving needle pricks cover every inch of your skin. If you knew how it felt, you would've succumbed weeks ago! The lust feels like being a teenager again, except ten more times as intense, with no need to hold it back or hide it. You feel like you'd never be able to shake this lust off, no matter how many times and how much you came. You drool with a stupid grinning look on your face, your yellowed, ochre eyes rolled back.

"Fuuuuck my hooole... Fuuuuck my hooole..." You repeat over and over again, goading your **** to fuck you harder, deeper, better than you've ever been fucked before. He's practically a jackhammer, slamming your ass so hard that it's threatening to break the bench you're on. He's lying on top of you now, fucking you like a dog, and you're just oh so pleased to be a bitch. You feel his cock twitching and getting more rapid, and you know what's coming. You ready yourself, ready yourself for the first orgasm in your new existence.

With a final thrust he empties his balls. There's so much, and it just keeps on coming! You feel your stomach inflating, his vile seed filling you up like a water balloon. Cum sprays from the seal around his cock, but it's not enough to offset the unyielding torrent. It feels like hours before it stops. When he finally removes his cock, your anus is like a broken fire hydrant. You moan, savouring this fullness. A minute later, after you regained your strength, you manage to limply get up, and you find yourself now able to sense your invisible assailant. You imagine it's like pheromones, or rather you would've imagined if your brain wasn't a mush of basic impulses. He's lying on the bench, presenting his ass in the air like a bitch in heat. It smells so fuckable.

"Fuuuuck my hooole... Fuuuuck my hooole gooood..."

Your cock rises quickly to the challenge. You grin. Being infected isn't so bad. You're going to have so much fun!
