Chlorine mutation

You immediately feel pain across your entire body, the acrid water eating away at your flesh. You and the two infected flail wildly, trying to balance yourselves upward. Your insides start to hurt as you accidentally swallow some of the water. An unbearable heat spreads through your body, unbearable like standing in a furnace; unbearable as if there was a furnace inside you! You realise you're done for, that there is no way that you'll be able to walk away from this unchanged, but yet still you try. You try your best to swim towards the pool's edge, but the visible infected from before grabs you from behind. Your skin sizzles in contact with hers.

"Waaaater... noooo escape! Ah! Soooo waaaaarm... hot! Aaaah! Hoooot! Youuuu sooo hoooot!"

You cry in pain and struggle against her, but she's much stronger than you. Gradually you weaken, until eventually you give up and submit to fate. It feels gooood. Your eyes unfocus and you go limp. Her clinging limbs start to ooze and meld into your flesh, becoming one, her legs fusing around your waist and her arms around your chest. Her breasts melt like warm tapioca against your shoulderblades. Not her cunt though; her hips still have free movement. She pants in your ear as her pussy now eternally grinds against your back, rubbing and mashing it, occasionally cumming but never truly, completely getting off.

"P-p-peeeerrrrrverrrt... cockkkkk haaaard... our cockkkkk... soooo goooood!"

You mindlessly agree, grunting and drooling as you begin to climb out of the pool. Your cock is indeed hard as a rock, and different too; larger, thicker, and your balls swollen and full. In fact, fused with the infected aside, you are different all over. Yellowish-gray skin, deep ochre eyes, chemical burns and pustules everywhere- you are an infected now.

"Fiiiind cockkkkk.... fiiiind pussssy... fiiiind body, waaaarm body! Fuckkkkk! Must fuuuuck!" Your conjoined companion gibbers in your ear, reaching a mediocre orgasm that makes her more **** for a fuck. You couldn't agree with her- with yourself- more.

As you slink off to find something to fuck, you slowly phase out, turning completely invisible.
