The worm evolves right in front of you

You continue watching the bluish translucent worm, it then starts changing again.

It takes several minutes but the worms tentacles around you seem to be changing in colour, from the clearish blue to a mild tan colour. You gasp and realise the worm is camouflaging itself to your skin!

You smile a little, only slightly alarmed at its change but are keen to see what else it does.

After its tentacles perfectly match your skin tone the worm then starts flattening its tentacles around you, changing them from soft jelly like mass to a flexible but very durable leather strap. It even seemed to suck the underside of them to your skin and blend the edges to your body, making them very difficult to tell where the worm ends and your body begins.

Last to change was the worms body. You watch in fascination as its colour also turns to a mild tan, mimicking your cock precisely. You giggle as you see your already impressive cock now look 50% thicker and longer.

"Oh my gods!"

You start to worry how you would fit a monster like that in any hole but are relieved when you see your "cock" shrink slowly to be slightly larger than normal. Evidently the worm shrank itself around you. You briefly lament that this means the worm will be even harder to remove now.

"Oohh!" That thought causes the worm to suddenly vibrate deep inside your pussy, it stops after a few seconds though.

A naughty thought crosses your mind as you lay down upon your back, your knees bent and hips angled. Your "cock" stands straight up proudly.

"I'm going to grab and.. uhhh.. tear and .. oohh!.. pull... fuck!" After only a few seconds of thinking, the worm has made you cum hard again. You continue thinking of removing it, it pushes you incredibly hard!

It pounds your pussy like a jackhammer and vibrates like a V8 around your cock. You feel yourself ejaculating so hard but don't see any cum spurt out. Instead what does appear shocks you; a long thin and very black tape worm! It spews out of you, at least a meter long and only several millimeters thick, then another, and another after that right in the middle of your orgasm.

"FUCK!!" You shout, the idea driving you absolutely crazy.

You pass out.
