Mojen bounded towards the dane, barely giving the small (compared to Mojen at least) dog any time to react. The time it did have was used to twist away in an attempt to run in the opposite direction, but Mojen simply used the change in position to mount the hound more easily. Her two cocks prodded against the dog's sex as it tried to break free from her grip. Mojen growled in delight when she found that the great dane was able to accept her twin pricks. She slowly slid one into the dane's wet pussy while the other made its way into the dane's asshole. Luckily, Mojen's cocks were still dripping with cum all along their lengths, so it wasn't too difficult to get them into either of the dane's holes.
The dane writhed about under Mojen's heavy body, either in pain or in pleasure, or possibly both. Mojen slowly pumped in and out of the dane. Now that she was Master, Bitch, and Dog, she would need a bitch of her own. Mojen flicked her long tongue against the dane's neck, "I'm going to make you mine", she grunted, thrusting deeper than before. The dane could only whimper in confusion, not understanding the english language or why she was being pounded by Mojen's thick dual cocks. Mojen pushed the dane against the ground as she drove herself in all the way to the hilt. "Such a good bitch already, and I havent even given you my seed".
Soon Mojen was wildly bucking against her new bitch's tight ass and pussy, there was no way for a wild hound like her to hold herself back any longer. Her knots swelled inside of her mate, making escape even more impossible. A pressure built inside of Mojen and she knew it was time. She thrusted in hard just a few more times before she found release. Her basketball sized balls pumped the dane absolutely full, the sheer pressure even pushed some of the cum back past the dam that was Mojen's swollen knot and the dane's tight inner walls.
The changes started coming upon the now entirely submissive "great" dane. Her body slowly grew and the hair on her head lengthened out. Bones cracked and popped as her internal anatomy shifted to allow bipedal movement. The creamy cock milk that had been given to her by her master nurtured her, making her grow strong. Her body became toned, muscles tightening and being built up as they had for Mojen but on a smaller scale. Where her tiny dog teats were, big balloons of breast milk filled out, like Mojen, she had 3 rows in total, although hers were bigger and weighed her down more than Mojen's. Mojen's bitch ended up being larger and stronger than any human or dog, but was still nothing in comparison to her amazonian master. The dane finally had her lower assets filled out, her ass and hips jutting outwards rapidly and two nubs sprouting from her groin. The two nubs twitched forwards in doggy dicks, which practically drooled with slimy precum instantly.
Mojen slowly pulled out of her transformed bitch, not wanting to damage the new toy she had gained. She brought both clawed hands onto the bitch's soft juicy ass. Squeezing tightly before slapping one of the furry mounds. "You will now be known as Danielle, Dani, or more likely... Bitch.", Mojen said, rubbing her cocks between the ass cheeks of her toy. Her pointed teeth flashed into a cruel smile of joy.
Dani was now able to understand her master's words, and knew to stay on all fours for her. A leash and collar materialized in Mojen's hands, it was similar to how the harness from earlier came to be, and perhaps it would return to Mojen as the harness did before, but for now, she affixed the collar around her bitch's neck.
