Give in.

Your body shakes in anger and your lips curl into a vicious snarl. You feel your body start to grow larger and larger, the clothes ripping and tearing off you. Your skin falls off you too, revealing short coarse red, orange and black fur all over you. A snout starts to grow out of your face and your teeth lengthen and sharpen until your snout is full of canines. Your arms fill out to the size of your formerly human legs, while your legs become like tree trunks. Steam comes out of your mouth with each breath. With another sniff, you turn your head over to the camper van. The ground dries and cracks under your feet as you plod your way over to it.

With your new height, you can see into the van easily. Inside, you see Moondance laying naked on the bed, while Starchild is kneeling between her legs, rubbing his cock up and down her slit. Your bitch's slit. Your vision turns red, and you punch through the camper's metal walls like they were paper and pull Starchild through the hole you made. His body soars through the air and he lands with two horrible cracks as his neck and back break on impact. Moondance screams and runs out of the camper on the other side. You jump up and land in front of her.

She collides with your iron hard abs and falls onto her ass. She gawks as she takes in your massive half-man half-beast form. You let out a bestial roar and she cowers before you in fear. She swallows a dry throat when she sees the forearm sized cock hanging between your legs.

Bending down, you pick her up and throw her face down onto the log that she and Starchild were sitting on. Pushing her head into the ground, you **** her hips up into the air, giving you easier access to her pussy. You rub your hardening cock along her ass, and she squirms beneath you trying to get away. You wait for her to exhaust herself before mounting her like the bitch she is.

"No, no, please, no." Moondance whimpers, as you rock your hips in and out of her wet pussy, as far as your cock allows you before being blocked by a canine-like knot that has grown at the base of your cock. "Take it out please. It's too big. It hurts." She starts up again, but you ignore her and keep thrusting, the need to breed her overtaking you. Planting your fists next to her head, you lean forward, driving yourself further inside her.

You keep fucking her like this for minutes, snapping your jaws above her head or pounding the earth with your hands every time she tries to get comfortable, reminding her of her place. With a loud snarl, you push forwards one more time and unleash your litter spawning seed inside your bitch, filling her completely.
