The potion burned Coal’s throat as he knocked it back, he almost gagged on the disgusting taste but he drank it anyway. He could feel it burning him inside as it travelled through him but he did not care he kept drinking. The burning entered his gut as he emptied the glass, he felt full and suddenly very calm and cool the pain gone.
Coal took a look round the devastated lab. Xan watched him turn around surveying the destruction. Coal had stopped growing, his horns twisted about his head like a turban of bone each a twisted 4’ long, the points ending facing forward like a rams. From Coal’s back rose a pair of beautiful bat wings, the long arms twitched as Coal turned opening and closing slowly revealing the deep purple depths of their folds. As he turned Coal’s tail flicked and swished Xan eye’s could not help but follow its path. Coal was still female though, a sexy seductive, hot female.
Coal raised a deep red hand and turned it over admiring the beauty of his long, clawed hand. He brought the hand to his big, full, breasts and brushed it lightly over his nipple, letting a deep pleasure wash over him. Why had he not changed? The potion he described should have turned him back.
“Xan?” he said turning to look at his 2’ muscled familiar. Xan could not help but tell him the truth something in that sexy voice, that body, he couldn’t resist.
“I did change some of the ingredients” he said grinning.
“Why?” Coal found he could not get mad about the change- he played with his nipple a little very much enjoying the sensations.
“I like you like this” Xan said timidly “you look great”
“I do, do I?” Coal slipped his other hand down over his flat belly and slipped a long finger down into his female sex. “And does this turn you on?”
“I…..I…urghh” Xan’s hard cock exploded demon cum all over the lab table. His entire muscular frame shook as a second, then third, and then fourth orgasm came over him.
“I guess I do then” Coal stepped up to the convulsing demon. He placed one of his fingers onto Xan’s still cumming cock and watched as the little thing suddenly doubled in size, more cum flying out of it. Xan’s entire body was shaking and twisting, his muscles pumping up, he seemed to be growing.
“You see” Coal explained “I just figured out what you must of done, what’s available in here for you to put in the potion” his almond, seductive eyes began to glow a little “I also know something you don’t” he continued to rub a finger over Xan’s growing organ, the little demon had not stopped growing and cumming.
“The potion you mixed up has locked me into this form, but if I collect enough Demon seed together then I can make another counter potion that should restore me to Human form. You, Xan happen to be the closest demon, so you’ll have to be the donor”
“I…urghh….don’t…..oohhhh….arggh…have….enough….cum….for….that” Xan panted.
“Oh but you do” Coal said seductively “all I have to do is keep enlarging this little thing” He rubbed Xan’s cock to empathise the point. It was six inches long now and over two inches wide. Xan’s demon balls had also grown, hanging oversized for Xan’s small body and most of the way to the desktop. Xan fell onto his muscular rump as his cock shot a massive bolt over Coals’ hand.
“See what I mean?” Coal laughed. He let Xan go; the familiar was not going anywhere.
Coal used a basic ‘tidy’ spell to fix the lab then began to collect the things he needed for his spell. All the time his wings opened and closed, his breasts bounced as he moved and his tail flicked against his legs. He was horny; he kept looking at Xan’s dribbling overgrown cock, that thick muscular body of his, if only he was not 3’ tall! An plan began to form, he needed demon seed, lots of it, why bother with the beakers and equipment if he could take it from source….hum….he felt his pussy begin to get wet just thinking about the idea…oh yeah, enlarge Xan and fuck him, right here on the lab table……oh yes.
Xan felt himself picked up, his soft over long cock tailed behind him as Coal placed him in a space clear of tables. Coal put Xan down and gave that long cock a tug, it grew and other 2 inches, Xan nearly fell over from the weight.
“What are you doing?” he said.
“Having you” Coal whispered back. Xan’s cock began to inflate just hearing his Master/Mistress speak. Coal grinned and began a soft chant.
