You pull away from her offered kiss, knowing the danger of even the slightest scratch from one of her fangs. "No, no," you tell her softly, seeing a slight hurt in her eyes. But it is a hurt replaced almost immediately with instinctual animal passion, as she lifts her ass into the air, turning around, presenting it to you.
The whole of the theatre is filled with the smells of sex, sweat and wolf musk. The sounds of passionate moaning and feral growling and howling surround you. It's a sensory overload now- everywhere you look you see sex, sex, and more sex. Your cock is throbbing hard in the sensual, sexual overload you're experiencing, and with a tug, you pull your pants down, revealing your rigid penis.
Without a hint of foreplay or gentleness, you slide it into Dina's still-changing slit and begin slamming away, lost in a sea of new tactile experience. The heat inside of her is almost unbearable, and the walls of her vagina twitch and spasm against your member as her body continues to change. The harder and faster you fuck her, the quicker her change gets, the more animal she becomes. With every thrust, more black fur grows on her pale skin, and her back bows slightly more.
With your last few thrusts, the pressure in your prick builds to a crescendo. As you pound rapidly, seeking a release, Dina's feral side is seeking a release of its own. Her beautiful face has gained a new beauty, her nose darkening, her face streching out into a fur-covered muzzle as you explode inside of her, experiencing an orgasm like no other.
The two of you collapse, spent; Dina from the change, you from the sex. You reflect on the night as the two of you lay there, on how bizarre the night has been, and wonder if you could tell your friends about it, let alone if they'd believe a word of it.
