Coal struggled to comprehend what was happening. All that he felt was this massive wall of flesh engulfing his massive body as he laid on the floor. The flesh pressed into his frame, every breath pushing Coal further into the ground. Yet his arms were not on the ground per se. His back felt as though he was resting on something, big under him.
He heard a cracking sound: the sound of concrete breaking as he and this other mass became too heavy for the floor to sustain them.
He felt groggy and unwell as he opened his eyes.
In his direct line of sight was a heaving chest. It was so big that Coal's head was engulfed by its cleavage alone. It heaved up and down, pressing him further into a phallic log as large as a tree trunk. Coal could only assume that this tree trunk that he had found himself between was his familiar, Xan's, titanic shaft protruding from his groin.
Coal managed to turn his head from the cleavage to look to the side. Huge puffy nipples the size of his fist capped the demon's mammoth pectorals. They looked swollen and tender, yet just out of reach of Coal's hungry mouth. Muscular arms larger than his forehead lay beyond that, the enormous biceps and triceps bursting with the power to move mountains. Coal caught a glimpse of a magnificent demonic wing in the background. Each wing appeared to be roughly the size of Coal, who was a massive nine feet already. They stretched out to the end of the room, shielding the young magician and his godlike familiar.
"M ... Master ... ? ..."
He heard a rumbling from the huge chest he found himself nuzzling against. The bass-like tone originated from his familiar, who after the last intake of his Master's demonic cum was only just becoming aware of its effects.
"Fuucckkk ... Master, I'm sooo fucking biiigggg ...."
More cracks could be heard in the concrete as the Demon shifted uncomfortably across the floor. Whilst the concrete may have been cold and unwelcoming, Xan's monstrous cock was like a pulsing, hot cushion: only semi-hard and yet at least as large as Coal himself. The back of his head rested at the base of Xan's enormous cock head, its foreskin moving as Coal adjusted to try and see past his familiar's massive pecs.
Unfortunately, Xan's muscles had swelled so large that his head was nowhere in sight. Coal therefore had to move himself from between the Rocks and the Hard Place to see how huge his familiar had become.
He started by pushing on the pecs. He used his right arm to grab a section of the steel slab of meat and slide his body out from under the Demon's form. As he did so, he neared one of Xan's nipples, which had grown slightly larger since he last saw them. It would appear that the longer Xan's protruding nips were left untouched, the larger that they grew.
"Hmmmm. I wonder if the same is true of other parts of his body .." Coal mused as he pulled himself further toward them.
As he did so, his familiar's cock twitched. Sensing movement against his swollen godlike body, his semi-hard phallus began to pump with demonic blood, growing larger and larger.
"Oooohhhh Master ..... I can feel you squirming under me. I feel so powerful now ... it's making me so much bigger".
It was true. Not only was Coal's Demon's cock growing (at a rapid rate I might add), his body seemed to be pumping up on its own.
