The Demon began to mutter in an uncomprehensable language, but Coal was in exstacy, and didn't even hear the words. The room began to swelter, and swet started to bead up on Coals body. The muscular monster stepped back for a moment, ripped Coals clothes off his body in a few slashes of his 4" claws, and flipped the boy over, exosing his high round ass. Coal turned his head to watch Him get on his knees, and plunge his muscled tongue into Coals ass. The deeper it went, the more pressure filled Coal, and he began to audibly moan.
After several minutes, He pulled out, a steady stream of hot spit oozing from Coals butt hole, and now a stream of cum oozing from Coals dick.
The Demon then threw Coal onto the stone floor, and leaped on him, skewering Coals hands with both his middle claws, the other claws bore into the stone around them. As His massive tongue began to probe Coals face, His enormous cock penetrated the tender ass presented to him. His fat dark purple head, was bigger than an orange, but with the strength of the Demon behind it, pushed itself in with no contest.
Coal begain to cry, tears streaming down his face, being lapped up by the creatures tongue, blood trailing from his palms, and dripping from his ass. It mercilessly plunged the length of its meat into Coal, only to pull just shy of exiting and plunge in again. Coal was immoble, his hands pinned to the stone, his ass high in the air, he began to shoot, cumming again and again, while swet rolled down his body, drenching him. Finaly, the Demons balls pulled high, and the creature roared, and bore his teath into Coals neck. He unleashed a torent of cum deep inside Coal, it quickly filled his gut, but couldn't escape! His stomach began to distend, slightly at first, than more and more progresive, untill he had a healthy gut filled with juice. The Demon didn't stop, however, and howled again, as the cum began to make Coals body swell more. Coals ass began to bulge out, plumping fat and round, full of spongy cum, and his chest filled up to, slowly becoming full and fatty, its muscles sagging heavy with juice. His entire body underwent this change, untill he was almost as swollen as the Demon, but soft, with no muscle tone, his skin stretched tight and slick. All his muscles huge and soft, and weighted with the Demonic seed.
