Leons skin begins to darken and turn black. He looks up at you, his eyes filled with fear and you can see they are starting to get watery.
His body is midnight black now, from head to toe his skin is pure black, and as you watch, his eyes turn black as well. The change is happening quickly.
He tries to open his mouth to speak, but when he does he finds a thin layer of film extends between his lips and prevents sound from escaping, his is no longer breathing and has no air to make a sound with.
His hair falls from his head in a shower of particles as his skin becomes tighter, feeling smoother and lighter at the same time. Then holds his hands out in front of him and sees them growing shinier in the dim light.
"He is going rubbery." you hear Eric breathe behind you. You take a step backward towards the light, and the stairs.
Leon shudders a little as his body changes. He is still looking at his hands, his fingers are sticking together, and then with a strange feeling of pressure they press in to each other and slowly merge, as do his thumbs. He is left with hands that are more like flippers than hands.
His stomach rumbles again and then abruptly stops as his insides are solidified in to black rubber. Between his legs his genitals are shiny and smooth reflecting light off their new black coating. He moves his flipper hands to his waist and runs them down his chest, making a little squeak. His eyes are gone, and his mouth is losing definition as his lips seal shut and melt in to his smooth face.
Between his legs you see Leon touch himself and fondle his black rubbery balls and dick. You shiver a little remembering how good it felt to be rubber coated as well, and for a second you find you wish you could have that again. You shake your head freeing yourself from the reverie of unwelcome thoughts.
Leons legs are stiff and his knees unbending, soon you see his thighs are pressing together, his feet and calves are swelling as well as they melt in to one. He is becoming a tube with a human torso atop it, and as you think that you see his genitals melt in to him too, leaving him smooth. His hands paw at the place they used to be and he looks up with his strange face at you and Eric.
The top of his head grows a little bump, and his entire head begins to decend in to his neck, and then in to his shoulders. His arms are slowly drawn in to his torso as it loses its definition and becomes part of his tube like body.
With a thud he falls to the floor and you see that he is becoming hollow at his base, where his feet were. With a flattening that spreads up him he bucks once and struggles a little and then is still as he is totally consumed by his change.
Where Leon once stood, only seconds later there is just a black condom that quickly shrinks down to the proper size. It lies on the floor, perfectly still.
"You think he is one of those now? One of those things from before?" Eric says looking at you.
"I dont know. We shouldnt leave him here though. I feel like we owe him one. There has to be a way to get him back." you say.
