The cougar grinned as she moved herself away from the cub filled wolf as she cried out in pain from her labour as she dragged herself to the den wall, the cougar smiled sadisticly as she then got down on all fours, she could feel the chemicals in her blood changing her once again, changing how she thought and how she acted as she slowly chased the pregnant wolf against the den wall.
"No please, just let- nnnnggghh!, just let us go" Cried the wolf as she clutched her contracting womb, the cougar grinned as she then turned her back to the wolf and lay back against her, lining her limbs up with the wolfs, taking her paws into her own so there was no escape, the wolf was confused as to what game this Female cougar was playing, but then a strange stretching feeling came over her legs, but when she looked around the cougar she let out a scream.
As the wolf looked around her swolen belly and towards her legs, only to find that the fur around her legs was now merging with the cougars, her grey fur now mixing and melding with the cougars sandy yellow coat, but no matter how much the wolf tried to kick her legs out in an attempt to get away, they would not respond, until finally their two sets of legs melded into one as the cougar stretched out her new legs, giving a sigh of relief as if stretching after waking up "What are you doing to me!?, let us go, I beg you" Cried the wolf as she struggled, crying out once again as her labour intensified, causing her back to arch upward, her belly and breasts now pressed against the cougars back.
The cougar then let out a moan as she felt a warm pressure in her hips, looking down at her new little baby bump, watching as she sank further and further into the wolf, causing her belly to grow, filling with the wolfs litter, the wolf beneath her continued to struggle as she saw her young being enveloped by this monster, but her struggle only seemed to pleasure the cougar as she grabbed at her swelling tits with her new arms and paws, the wolf quickly noticing that all the remained of her former self was her head as she began to cry, feeling her back being enveloped by the cougar.
The cougar then heaved herself up and looked over her new form, her fur had turned to a dark rich brown, with ice white fur over her new G cup size breast and enormous round belly, she giggled as she felt her new brood stretching her womb and kicking against her sensetive skin, rubbing her belly on slow circles as she took in her belly in all its glory, along the front of her belly she could feel six milk laydened teats across her belly, and her hips had widened so much that from behind she may have been mistaken for a grizly bear, her new ass was even more round and bouncy than before, giving both cheek and spank as she and the wolfs head next to her own let out a lewd moan.
"Well then my canine friend, it was nice to meet you, and thank you for my new children" giggled the cougar as she then put one hand on the wolfs head and the other on her own and began to merge the two together....
