You get dragged into her instinct, before class.

"Okay, try and stay still while I'm in class, okay? Even if you're inside my inner beast's womb, I'd hate to cum while a lecture's on. Okay?" A statement you can.

Worse, is how that flesh that's symbiotically bound to you, is gently massaging your dick while you hear nothing but muffled voices, from outside Lyla's thoughts herself.

You vaguely recall her learning about Unbirth 101, taking notes while quietly complaining about not being able to pull you outside of her, since last night. Much to some chuckling, and cheering from outside. When you felt satisfied, that no reformation centre's going to pull you out of Lyla, by the time her instinct's done marrying you to it.

Mine, you thought, as with one instinctual swallow, you felt your body be pulled in deeper, in pleasure. A sensation shared by your hostess Lyla.

"Uh, shit... I need to go to the bathroom!" You vaguely heard, as you felt pleasure build up, as much as horror that you should hold the urge to cum, in. A fact made impossible with your both your sexes are being melded, as your limbs is being assimilated at an accelerated pace.

Just as you lost conciousness. You came to some dreamlike forest, your dick jizzing right into the voracious maw of the feral beast that unbirthed you, in that Full Moon.

"Awoo~" Sang Lyla's feral instinct, all four paws pinning you down, as you felt your skin be pushed tightly into her sticky fur. Dripping in nothing but much denied vaginal fluids?

You couldn't help but feel you're going to be fucked for eternity now. As that instinct purred into your ear, on how you'll complete not just her instinct, but Lyla's very soul with your unholy unity.
