Trying to wrestle his head out of the naga's grip, Ritter's eyes started to grow wider and wider as he watched that head descending downwards. The first drop of that strange slime hits his face like a bolt of lightning, his whole body almost instantly beginning to squirm and writhe in the naga's grip, his tongue starting to detect a strange flavor filling his mouth. Like bailing water from a sinking ship, his tongue tries to push at the viscous liquid, shoving it out to dribble down his chin, but that resistance lasted for only a moment before his captor suddenly began to shove the whole of that head down against his face and mouth, the thick slime slipping despite his tongue's protests. His struggles growing even more violent as he realized he couldn't breathe with that black ooze filling his mouth, gentle, terrified whimpers start to echo out quietly, the rabbit trying to resist the instinct to simply swallow the material filling his maw. The attentions at his cock were almost forgotten at this point considering his new predicament, Ritter quickly realizing that unless help came, there wasn't much he could do to resist.
