Gus barreled his weight into her as she righted herself, humping furiously even before he wrapped around her waist. Again, his fucking was clumsy, his claws digging into her sides as he hungrily tried to fit his cock inside her. He threatened to penetrate her ass again but he reassured his grip and dove right into her snatch. He ruffed out a satisfied bark, slammed her back into his cock, and then gave her his entire weight as he slamfucked her into the ground. His orgasm took a lot longer this time, barreling into her abused pussy, reshaping it as his cum began leaking steadily. His knot swelled up, jammed in and out of her cunt a half dozen times before locking up. He fucked her for another minute before what felt like pints of semen began pouring into her womb, mixing with Roccos and filling her up to the brim. Over the next few hours her body would begin producing more eggs and dropping them into the pool of fertile canine cum. Chance would determine which dog's seed would take.
Exhausted, Gus layed his head on her shoulder, staying atop his locked bitch for a full 30 minutes before his knot deflated and he slipped away from her.
Rocco had recovered in that time and took his place, having another go at the properly situated doggie fuck toy in their kennel. He was a lot more aggressive this time, wrapping his jaws around the back of her head, drool spilling over her neck as he claimed her, tied her, and dumped more cum inside her belly. When he was done, he slipped off her back, leaving his knot tied as he stood ass-to-ass with Lily. Gus, thirsty for more pussy, mounted her side and humped wildly at her hip. Eventually he managed to swing his leg over her and Rocco's union and jam his cock into her asshole, filling, tying, and spraying inside her once more as two thick knots pressed against each other on either side of her holes.
