Gentleheart sat on the hill, her glossy white fur shimmering in the moonlight. Warmth radiated out of her hindquarters, and she waited for her mate to show up. And there he was - Butterflywing padded up to her, and took her roughly. Their thin lips collided with each other, and Butterflywing forced her mouth open and explored her mouth with his rough tongue.
The two had been meeting on this hill for the past week now. They were littermates, meaning it was forbidden for them to be mates - But she craved his presence, his love. She pulled away from him, breaking the kiss, her tongue hanging out of her mouth. A thin strand of saliva connected their tongues, and she roughly kissed him again, then moaned as he bit at her neck.
The warmth in her hindquarters grew, the longing for his penis to be inside of her. As he bit her neck and sucked on the tender flesh, she nibbled on his ears, resulting in a chorus of moans from the two. After a while, they broke apart again, and Butterflywing noticed her heat.
Gentleheart squealed as his cold nose pressed against her soft folds, shivering as he sniffed at the delicious scent. His rough tongue flicked out and rasped against her wet cathood, causing her to moan loudly in longing. His tongue licked so achingly close to her entrance, and she kicked out her leg in frustration. "God damn it, Butterflywing..." She grunted.
Finally, her incestuous lover allowed his tongue to enter her, causing her to moan loudly with pleasure. It didn't take long for her to spew out her cum, and he licked it up and kept in his mouth. He roughly kissed her again, forcing her to taste her own cum. She swallowed her cum eagerly, and they broke apart, only for him to shove her to her stomach and place his already-erect penis into her mouth.
She sucked obediently, gagging as he began to thrust wildly. She sucked and drew her tongue around his large penis, and he finally came in her mouth. She swallowed his cum, and he forced her into a hunter's crouch. "Oh, Butterflywing, I don't think I'm ready.." She whimpered as she felt the tip of his penis poking at her entrance. "Oh, don't worry, it'll feel really good, my little slut..." He snarled, and pushed into her at full force.
She let out a cry of pain as he thrust into her hard and fast, and she could hear the groans coming from him. Blood leaked out of her vagina, but he continued to be a sex savage towards her. Suddenly, he pulled out, then ground her head to the dirt and forced her hindquarters to raise. He dipped his tongue into her asshole while stroking his paw roughly against her vagina, causing her to moan.
Her other brother, Brownfur, stepped out of the shadows, his large penis fully erect. His paws were coated in cum - most likely him jacking off to the scene before him. Butterflywing snuck under her and forced his tongue inside her mouth, and Brownfur lined up his penis with her asshole. Butterflywing smashed into her vagina, and Brownfur fucked her asshole. This went on for a few painful hours before they pulled out and just left her there in a puddle of cum and blood.
Gentleheart heaved out the last kit, panting. There were four kits - A tortoiseshell she-cat, a light brown tabby tom, a black-and-white tom, and a white she-cat. Brownfur and Butterflywing looked at the kits - Their kits. "Stormstar," She whispered shakily to her mate. Ever since that night she had stopped seeing her brother and found love in their leader. He thought hat these kits were his.
"These aren't your kits."
