Jennifer brushed her hand across Devin's neck as he looked closely at a pack of beef patties. He turned towards her, "Hmm?"
"It's getting late. The moon will be rising soon after sunset tonight. We should get home," she said, glancing meaningfully at the storefront window. The light outside flared reddish orange as the sun hung low. Devin followed her gaze and nodded.
The pair quickly picked up the rest of their groceries and checked out. Jen's brown hair looked like a curtain of blood in the light of the setting sun, and Devin felt a flare of excitement inside of him. His inner wolf rose slightly. He focused and quelled the instinct to shift. That would happen soon enough.
Jennifer drove home with a lead foot. The sun had set, and her wolf, too, was stirring. She felt hot all over, and Devin didn't seem to be doing much better. He kept twitching in his seat. They were cutting it close. Before the couple had met each other, each full moon was a painful test of endurance. They would lock themselves away to keep other, regular people safe. And if they failed to contain their vicious selves, it usually meant several dead animals in the surrounding area and a lot of grief covering their tracks.
Now, the two werewolves had something much more... fun, to focus on each full moon. Each other. And this particular full moon was going to be extra powerful. The super moon was rising.
"Come on, quickly," Jen said, grabbing their bags and closing the garage door. They went inside, both becoming increasingly irritated as the horizon began to glow a soft silver. Not enough to overpower them. Yet.
Jennifer bolted the doors around the house and set a timer for them not to be opened for twelve hours. The couple had spent a long time proofing their house to keep them inside during their involuntary change. The windows had metal shutters that rolled down and locked into place. The doors, all heavy wood with a steel plate interior, had three deadbolts on each. Even the chimney had metal grating overtop.
After their food was put away, they moved to the living room. Before settling, they undressed, knowing that their clothes would be ruined if they didn't. Devin sat on the couch, clutching his head. Usually shifting wasn't painful, but during the full moon, werewolves lost control of how far they could change. A full shift involved bones reforming and body reshaping, and could be agonizing. Devin's skull was currently trying to reform itself, giving him a massive headache. Jen rubbed his temples, ignoring the pains emerging in her own body.
Then the moon finally crept over the horizon. The skylight let the cool silver light into the living room. Devin groaned. "Let go. We are safe," Jen said, caressing his cheek. Devin stopped shaking, and when he looked up at his mate, his eye gleamed with golden ferocity.
The shift was immediate. His skin sprouted coal grey fur. His chest deepened, and his legs grew longer. Fingers and toes tipped with claws, and a long tail grew from the base of his spine. His head was now that of a wolf, with a strong, boxy muzzle and liquid gold eyes. Jen glanced down to see that his member had also changed, as it did every month. Huge, with a row of bumps down each side. A pulse of excitement shot through her. "Come and get me," she said, feeling her wolf rising to meet the moon.
Jen leapt away from Devin, slipping into the shadows of their house. He followed, panting in excitement. The half-transformed woman darted through the kitchen, jumping onto a counter with ease. A vase they'd left out smashed to the floor. No matter. "Get back here," Devin growled with thick, animal sounds.
"If you want me, you'll have to catch me," Jen gasped. She was holding off her full shift, keeping the game interesting. They moved to the dining room, Devin halfway slamming into a bookshelf as he tried to grab Jennifer with a clawed hand.
Devin herded Jennifer into the guestroom. There was no way out here, and Jen knew it. She backed into a corner, glaring. "Stay away!" she shouted, lashing her wolf tail which had emerged a few moments ago.
Her mate advanced, growling with lust. He jumped, body colliding with hers. Jen let herself slip then, so that she would be stronger to fight his advances. The prospect of mating overwhelmed any pain she felt as her body morphed. Pale brown fur with a white splash across her throat and deep green eyes looked up at Devin.
Howling, Jen shoved Devin off her. The larger male was undeterred, however, and made another grab. He used his teeth, biting at the back of her neck to establish his dominance. Jen struggled weakly, acting as if she detested his actions. She felt her pussy twitch as Devin shoved her against the bed. "You're mine," he rumbled, flinging her over his shoulder.
He carried her to the bedroom. Padded cuffs hung from the headboard and foot of the bed. Jen thrashed, but he got both her legs and one arm strung up. She slashed his shoulder with sharp claws on her free hand, drawing thin lines of blood. "Silly girl," Devin said, gripping her wrist in his fingers and shoved her arm into its binding.
