Luke didn't know what to do, this uncontrollable slime spreading quick, covering his body. The worst thing is that this thing is arousing him. It's partly his fault he thought, as he always had a fascination with living goo.
The goo clung to his skin tightly, defining his body features. At this point it may as well be a part of his skin.
Luke continue to panic and tries to rip off the living goo encasing him, but to no avail. The portion that he rips off merges back to the living goo, and the ripped portion is quickly covered.
The goo has now covered Luke's entire torso, and has just completed covering his toes. The ring device and the goo surrounding it also began stimulating his dick, kind of like the goo is masturbating Luke's dick for him. Luke moaned in pleasure. He tried to stop the device from this pleasurable stimulation, grabbing his penis in an attempt to stop the stimulation, but as soon as he touched his manhood a wave of pleasure waved through him.
"I can't.... ahhhh.... I can't ejaculate! Ahhhh...." Luke tried to say as he moans, trying his best not to cum as the semen would probably make everything worse.
He let go of his dick, thinking that it would help him not to give in.
