I felt a strange rush to my cock as I looked the newly grown imp up and down. "Holy shit, you grew."
Runt chuckled at my shock. "Of course I did, you didn't expect me to give you a good time while being only a foot tall did you?"
I blushed sheepishly. "Well I guess not, I just didn't know you could do that, I've never been with a demon before. So...what else can you do?"
Runt gave his mischievous smile again before leaning in, whispering in my ear. "Anything you want buddy...as long as I have your permission."
I continued blushing but remained firm. "Well then...I give you permission...to do whatever you want."
Runt certainly didn't expect that, the shocked look on his face was evidence of that. He'd been with plenty of mortals but never one so...open minded. "Are you sure about this? My tastes may not be to your liking."
I just nodded. "That's ok...I trust you."
Runt stared at me for a moment more before smiling lightly. "Very well, but remember, this was your choice." He had me sit up as he got on his knees, his tail writhing in anticipation. Then like a sculptor the demon started to massage my skin. Like clay it molded to his will as my arms merged with my side's, smoothing them away with gentle strokes. I groaned loudly at the sensations of the process and the fact that I was completely at the demons mercy. Runt smiled as he continued, rubbing my torso and chest as it started to round out into a cylinder. Moving down my body all of my hair vanished at his touch as he went down to my feet. He rounded them out smoothing them and stretching the skin, the bones and muscle fading away as something new filled the empty space. Two somethings actually, big, round, and sensitive as they swelling in my former leg skin. Satisfied Runt returned to my face, smiling before kissing me. With each second the intensity the, it became hotter,my mouth more sensitive, my saliva...thicker? As he kissed he worked my neck stretching the skin out, up, and over my head where it merged like a hood. Finally Runt finished, sitting up on his knees, admiring his work.
"How...do I look?"
Runt smiled, his demonic cock dripping hot pre like a faucet. "See for yourself."
Runt moved aside so I could see in the full length mirror by my closet. I no longer resembled human save for my face which was surrounded by thick skin. My body was a long fleshy tube while my legs had become a mass of skin over two orb shaped masses the size of exercise balls. I didn't look human, but I did recognize the shape. "A cock...you turned me into a giant cock."
"Ah, but cock s don't usually have a cock of their own." It was true, of everything he touched the only thing that remained aside from my face was my cock, still hard and leaking, nestled above my testical legs. I groaned loudly as Runt stroked my cock and my body, both equally sensitive, as hot pre leaked from my cock...and my mouth.
"So, what shall we do now my friend?"
