Suddenly, when making out with your huge buff naga lover, you hear windows shattering followed by a big roar outside your apartment. You both look through your window and see a monstrous green latex werewolf exiting the gym next door. He's a whole 12ft tall and looked ridiculously buffed. His frame was so packed he could probably destroy buildings by himself. The werewolf then seemed to sense your presence and pounced towards you. You barely had time to react before the monster broke through your window, breaking half the wall, and landed directly on Steve. The naga dropped on his back and tried to lift the beast away from him, but even his four arms couldn't lift the werewolf. "MORE MEAT" The monster sreamed as he pinned him down and mercilessly fucked Steve with his 30 inches canine dick. He seemed to be completely animalistic and without reason. Steve screamed in pleasure as he was streched beyond his limits. Seeing this giant monster turned you on. "These wild symbiotes don't deserve to rule." Your symbiote said in disgust. "DOMINATE HIM!" You felt compeled to take control of this beast. You quickly positionned yourself behind him and rammed your 22 inches dick in his werewolf ass. This made you grin as the beast immediatly screamed in pleasure but at the same time it tried to pull away from Steve to confront you. "You're not going anywhere" you said as four black thick tentacles burst from your back and grabbed his arms and legs, spreading them appart. You then lifted his whole body in the air to keep him from escaping. He roared and pushed in all directions with his strong muscles but the tentacles absorbed the blows and kept him bonded. Steve was now able to free himself from the clutches of the werewolf, so he got up and forced the maw of the beast open with two arms. He could feel his symbiote urging him to dominate him as he face fucked him with his dick. The monster now screamed in hatred as you two fucked him senseless. He started growing as a last resort to survive the assault, his arms inflating even more, his pecs getting so bloated they touched the ground even with the tentacles lifting him 5ft high. You can feel the muscles of his butt growing, making his entrance feel tight and hard. His arms became hard to contain but Steve came in with his two free arms and grasped them. Your combined strenght was enough to contain him. You grinned in delight, even with this you were still on top. And so you plunged your dick in him with all your might while roaring like the monster you are. This unleashed a loud moan from him as you felt something with your dick. Almost like you broke some kind of flood gates within him. You could feel the goo entering your dick. You pulled head back and screamed in pleasure. "HAAAAAAAA" You could feel your dick absorbing him from the inside. This made your whole body grow. "MOOOOOOOOORRRRRRREEEEEEEE!" Your pecs instantly grew 2ft forward with your nipples getting visibly fatter and juicier. Your arms grew bigger than those of the werewolf, you flexed your biceps with glee as you saw them grow more and more until they were twice as big as the werewolf's head. You saw the beast had now shrinked to his original size. You retracted your tentacles as you grabbed his waist and plunged him on your dick. Your newfound strenght made his body feel like a sex toy as you fucked him harder and absorbed more of his power. Thick sharp claws grew on the tip of your fingers and feets. You grew and grew until your head hit the 9ft ceiling. You then turned around and jumped through your broken wall and down on the street, all while keeping the monster on you. People around you screamed in fear as you grew up to 12ft tall. This made you roar in delight. Your dick now seemed bigger than the werewolf could handle as he panted with his long slimy tongue lolling out of his mouth. You then retracted your dick from him. It was now 62 inches long and 20 inches thick. "You don't deserve my seed" you said to the beast as you pushed him inside your torso. Your strength was now no match for him anymore, he was completely absorbed into your body. You unleashed a thundering roar in victory, all windows in the city broke from the sound as you were on the edge of cumming. You finally grew to a gigantic 15ft tall. You grabbed Steve from your broken window and brought him to your dick. He was the only one worthy to take your seed.
