His whole body wiggling about in protest as he felt the naga's grip grow stronger and stronger around his muzzle, Ritter began to whimper in both fear and need, both wanting to escape and wanting to simply give in to the incredible attention being lavished on his length. His paws clench and unclench almost involuntarily as he continued trying to resist his captor's advances, though the continual, building pleasure on his groin was making it nearly impossible to concentrate. His whimpers soon became low, needy moans, echoing up through his clenched teeth and closed mouth, a sure sign that his will was steadily weakening. Feeling the rippling, massaging maw working all across the tip of his cock, the rabbit's eyes begin to roll back, his concentration lapsing for but a moment. Of course, even that was too much, and before he even realized it his maw had opened a good inch, and while he was able to stop it from opening much more, the damage had likely already been done.
