Rob could´t believe what had become of Bianca!
He hoped to find her before it was too late, but the once beautiful girl had turned into a fexa stem, with each of her limbs transformed into dripping cock-tentacles.
Rob tried to run, as he understood that Biance wasn't able to hear him anymore and just had become a monstrosity of cum dripping, twitching genitals with the sole purpose to feed spitbugs and transform everything in its grasp.
Rob was grabbed by the tentacles before he was able to turn around. screaming, he was pulled deep into the thicket of oozing penises. The smell was awful, as the viscous fexa cum started to dissolve his clothes and the warm flesh of throbbing cock-tentacles started to slither over his skin.
In the middle of the stem, Rob finally saw Bianca´s new form: Her arms had become veiny tentacles as her lower body had merged with the stem. Her head had turned into a weird mix of a drooling cock covered in foreskin and massive lips, that seemed to suck in air aimlessly.
Rob was pulled closer to the slurping opening that must have beed Bianca´s mouth once. He tried to fight the grasp, but soon was violently pushed towards the wet, salty lips of Biancas new head, as she started to kiss him deep-throat.

She was sucking something out of him! Rob felt how his skin started to feel softer and thiner, his chest started to feel a bit heavy, as he noticed the 2 massive fat-pads forming under his breasts. His weird boner had shrunker between his legs, his dick was turning into a pussy!
Against his will, Rob started to enjoy the kisses of the fexa, as he willingly started to spread his legs to welcome his new mistresses hard cocks.

Fully turned into a fexa spawn, Rob enjoyed the pleasure, Bianca was giving him. He would do anything to make his new mistress happy, and he felt how he must spread the word to others! Others needed to experience this overwhelming pleasure as well!
With these thought planted in his brain, the stem let go of her spawn to search for new victims in the forest.
