Broodmare

The voices in his head urged him to breed her, to fuck her until she bears an army of offspring. His mind and body was overwhelmed with lust once more before he knew it he was on top of her tearing threw her clothes and penetrating he pussy once more. She moaned in protest but the magic infused within her began to glow once again. In his mind as he fucked her he focused on the runes, felt the flow of magic within his body down into his loins and through his cock which swelled and glowed with arcane power. When he climaxed the magic flowed into her feeding the runes on her body, this time they grew darker like ink. The tattoo etched into her body wrapped around and as it did so altered her, her hips grew wider, her pussy deeper and fatter. As it made its way up to her bosom her tits swelled two sizes up from b to d. Finally the inscription ended in a collar around her neck. They stayed there knotted once more but this time he did not pass out like before but she was lost in ecstasy as he was tied to her. Her belly looked swollen with cum, and he could see his prehensile penis squirm around, each wiggle causing her to let out a soft moan. Grok easily lifted her off the ground as they were locked together, he sat back against the wall with her on his lap contemplating what happened as he played with her body tracing the runic tattoos. He seemed to know what most of them meant, not only magic for changing the body but there were those to alter the mind. As he played with her tits a few drops of milk were squeezed out onto his claws, he licked them off it was sweet and creamy but his senses detected a faint trace of mana within it. The runes around his bosom could be made out to something roughly translating to " Enhanced Nourishment and Rapid Growth". After a thorough examination of her body his knot was deflated enough to pull his dick out. He placed her down on the straw mattress to let her rest. He continued to be aroused his body refused to calm down, it seems one will not be enough to satisfy him. After desperately masturbating for more than an hour and several climaxes he passed out laying in a pool of his own jizz.
