Yes

After a while, the both of you wake up, the feeling of your eye stalks pushing out of your wet, fleshy heads oddly feeling normal. You also feel your sensory stalks pushing out the corner of your mouth. The two of you turn your eye stalks to look over each other's New bodies.

Looking at Jean, you see the black latex that began covering you two before became organic and fleshy to match a slug's moist skin. Her body shape looks similar to her previous human form, except now she appeared to be a bit plumper. Her breasts seem to have melded into her body, being near nonexistent. Her arms appeared to lack joints, as well as her hands, only leaving her with a singular fleshy slug foot like hand on each still with thumbs.

Looking down, you see her hips have actually widened, being plump and squishy. Jean's abdomen was greatly rounded and plump, you know that your 'children' reside within. Inwards towards her crotch, there stood an alien-looking appendage flopping out, resting on her bulging stomach. It's a bright, translucent blue hue and fanning, malleable flesh resembled that of their new slug relatives.

Interestingly enough, her legs did not merge together into a large singular foot and skirt as a normal slug would. Instead, she still retained two limbs but calling them legs would seem odd. While her thighs and shins seemed to still exist, albeit with muscle replacing bone, Jean's lower legs resembled the feet and skirt of a slug, even trailing behind her upper 'legs' rather than forward.

Without even looking, you know you are nearly a mirror image of your slug 'spouse' The two of you also seemed to have shed the idea of 'male' and 'female' Though you lack vaginas and both sport large male slug cocks, you anus seem to have been converted to function as itself as well as a means for insemination.

Yet, the two of you 'know' the best way to spread slug is by directly filling other humans up with your children through your mouths and newfound slug penises.

The two of you slowly get up in the alcove, rubbing each other's bulge full of your slug children with your slug hands. Jean smiles at you while you smile back, both your mouths still very human-like.

"We have so many children, my slug~ We will bring to this world a new way of life~," you say, your voice still retaining some of your same tones, though now it's sounded is filtered through moist flesh.

"And we shall, my slug~ Soon, all humans like us before shall birth our children to spread across the world~" Jean replied in her own wet filtered voice.

Without even looking, your sensory stalks detect the local slugs nearby that changed you both were gathering and waiting, as you two were their new leaders and forerunners for the future slug kind. You also happen to sense another presence in the swamp as well...
