Susan's boy friend, Andrew, manages to grab onto her wrist before she reaches the ground, "Whoa, watch out there, I don't want you falling into that stuff there- whu- what is it anyways?"
Susan put her arm around Andrew's, and said, "Man I have no clue, wheres Jen? Shes usually in here."
"Wait, didn't you take me here to see Melanie? Why are we in her little sister's room?"
Susan took a step back from the dark goo, "That sounds right, I guess I just- I kinda felt drawn here?"
While Susan was questioning her consciousness, Andrew poked at the puddle of goo with the tip of his shoe, suddenly, a dark mass rose from the puddle, and after a moment of hesitation, it lunged at Andrew's shoe and globbed onto it. Luckily, his shoe was untied, and simply slipped off and into the puddle. Before either Andrew or Susan could react, a thin tentacle shot out from the puddle and wrapped around Andrew's leg and pulled him down, his arm slipping from Susan's.
The latex slid under his clothes and quickly slipped them off of his body. He reached out to Susan, who took hold of his hand, but despite her best efforts, was not able to pull him away from the puddle, "Mel! Help! There's this weird black goo in your sister's room and its taking my boy friend!"
It wasn't long before the latex had removed most of Andrew's clothes except for his other shoe (it had managed, however, to remove both of his socks) and covered most of his body. To compensate for the extra height on one of his feet, the dark latex formed into heels on both of his feet. Andrew tried to scream but the latex covered his mouth just after he opened it. It coated his lips, making them dark and full. Against his will, Andrew's hands moved to his flat stomach, where his nipples would be had they not been covered with latex. There was still a lot of latex left on the ground, and it quickly ran up his body to his hands where dark breasts began to form. It also went to his hips and cock, which was firmly erect, soon he had a distinctive hourglass figure, with a penis a bit longer than a foot. The last of the latex covered all of his head, except for leaving holes where his nostrils were. There was still quite a lot of the dark goo, as it was from two different people, the excess went to forming long tentacle like protrusions from his head, similar to hair. By the end of all this, Andrew could most definitely be mistaken for a woman, if not for the large cock extending from his lower body, but even then it was hard to tell.
