Tendrils of Writhing Darkness (Patreon)

He knew what he was signing up for: a military experiment designed to create soldiers with impossible strength and power. As the goo invaded his body and he felt his body start to respond to the creature's presence, the rush became overwhelming. He felt as his skin desperately clung and tightened around his engorging musculature and began to moan.The creature had barely begun to transform him as he slammed his arm on the glass of containment, panting. He locked eyes with the observers, tendrils whipping and penetrating his pulsing form as the creature coated his arctic white fur with inky, slick, writhing darkness. With a booming growl unlike anything they'd heard before, he demanded more, with the implicit tone that refusal wasn't an option.
