Mina leapt from her slumber at the sound of stalking footsteps. They'd been following her for a few days, never close enough to risk getting caught, but always on the fringe of Mina's attention. Unsure when Sally's cum would unleash its effects on her body, Mina opted to lure them in before she was defenceless. To that end, she feigned sleep until they chanced approaching. She didn't pause to register their appearance, only grabbed at their wrist to prevent escape.
"Who are you?" Mina asked the struggling pursuer, though her grip prevented any chance of escape. They didn't answer at first, instead pulling at her fingers in a bid for freedom. To her surprise, it was a Monster, humanoid in shape, with a short snout and long ears flopping on their head. Bundles of fluff warmed her neck, more spread out on her wrists and ankles, with a cute ball of the stuff quivering above a shapely rear.
Mina hefted her up by the arm, eyes drifting to the cow-like breasts. They had to be on par with Edna's pair.
"I'm not gonna hurt you," Mina said, though she didn't let go, "Tell me your name and why you've been following me."
"Oh, in that case," the bunny creature relaxed, pink nose twitching as a salacious look hooded her eyes and tilted her lips, "My name's Louise. I wasn't tracking you specifically, just the smell of cock."
"Why not your own?"
"It's my season," Louise explained and rubbed her soft belly, "Sure, I could use my own, was even about to when I caught a whiff of you." She licked her lips, now palming a breast.
Mina knew what she wanted. It'd take an inexperienced and naive mind to mistake Louise's intent as anything but sexual, more than that, she wanted to breed. Rabbits are the same in any species, Mina thought. Was she really going to fuck this stranger? It could be another Sally, looking to trick her out of her possessions. Although she only cared for the compass. There wasn't anyone nearby either, none that Mina could discern. Beside all that, Mina hadn't cum for days, too worried by what Louise might've done.
"You're in luck," Mina said, sighing as her cocks slid from their sheath, thickening on their way to erection, prodding Louise in the navel as if to stake their claim, "I need some relief too."
It was easy to judge a Monster for their sexual appetites, but rarely had anyone experienced it themselves. Mina pinned Louise down, cocks situated at her opening, intent on pumping her womb with every drop of seed. Both moaned in harmony as she pushed inside, the snug tunnel closing around her rigid lengths and pulling them further, until the heads nuzzled the rabbit's cervix.
"You're so thick," Louise groaned, "Hmm, like a centaur."
"More than that," Mina said and pushed harder, forcing the last few inches past the barrier, her barely inflated knots stretched her new lover greater than ever, earning a startled cry.
"Those feel like... like knots."
"Uh huh, and these," Mina pulled back, a wet pop echoing amongst the neighbouring trees, and groaned deep, "Are my spines."
"What are you?" Louise asked. If she was afraid, it didn't show through her pleasure, juicy thighs pulling Mina back in. The Chimaera grunted and slammed the rest of the way, angling her thrust to mash her upper knot against Louise's clit and balls. Her own cock flopped into the open, drooling pre-cum on the rabbit's stomach fur. Two very distinct bulges framed it on either side and, as Mina closed the gap, pushed against Louise's ripe tits.
"Never mind," the rabbit gasped and hooked her legs on Mina's hips, "Just fuck a litter into me."
"Gladly." A familiarly strange heat flooded her veins, seeming to pour from her fingertips where they grasped Louise by the hips, the bunny tightening around her. That warmth flared brighter. Mina hunched over, fangs gleaming with venom as she sank them into her lover's neck, muffling her own blissful cry. Orgasm remained a distant goal however.
As Louise clamped onto her, nails grinding into her scales, Mina welcomed the bliss of transformation. Her cocksleeve gasped in broken breaths, pulse racing through the walls, grip weakening as the muscles stretched. Both her tumescent pricks gorged on the corrupt pleasure surging within. The once tight but welcoming hole became a corset around her members.
"You're growing inside me," Louise panted, kegel muscles working to grind into every fat vein on the cocks, "Oh god, I can see them through my fur. You're stretching me more and more. They're moving between my boobies. Oh fuck, let me, hmm, fuck me, fuck me, fuck me..." She wrapped her arms around her and Mina's breasts, squishing them together around the Chimaera's massive shafts. Two round heads bumped her chin, forcing it back.
They didn't stop until they reached beyond even Mina's head. The far smaller Monster beneath her, stretched and trapped on her shafts, didn't stand a chance of seeing the ends. Mina pulled her fangs out, more of her aphrodisiac poison dripping between her dual pillars into the rabbit's mouth, who shuddered and screamed in sudden bliss. In her big, innocently lurid eyes, Mina saw a black streak dye the scales across her own eyes.
"You're gonna knock me up so good," Louise moaned, voice shaking with every thrust of Mina's powerful hips.
