Vieria was a bit annoyed was given her next breeding assignment by ROCC headquarters. Chara, one of Vieria's only friends in the outlands, created a tentacle that was very good at producing eggs & gave one of them to Vieria as a gift. Vieria reported this back to ROCC headquarters after the exchange, as all entities from the badlands have to be examined & protected once entering Cave City. Vieria's team was chosen to oversee the standard tests that would have to be run on the tentacles in order to analyze them & their capabilities before mass production & distribution to the residents of Cave City. This specific tentacle type employs a psionic hivemind in order to transfer information to its offspring & to the rest of its hive, meaning the tentacle was able to learn & remember the faces of those that were good at breeding it. One of the first tests that were run was the reproduction capabilities of the tentacle, as Chara stated herself that the tentacle was an apt reproducer. ROCC Command chose Vieria out of all of her team members to act as the subject for the reproduction experiment, as her body's fine-tuning & general reproduction capabilities are top-tier when it comes to general breeding in all aspects.

Vieria upset that she drew the short end of the stick, prepared herself & entered the designated breeding room where the tentacle was held. As soon as she had entered the room, the tentacles inspected the intruder & seemingly determined that it was capable of reproduction, as a tentacle immediately stuffed her right breast & her ass. The tentacles quickly got to work on coiling through the deepest parts of her holes and implanting her with one egg after the other. In as little as five minutes of her entering the test room, she's now what we see here. Her right breast has had eggs shoved into the deepest parts of her milk ducts, leaving no space unfilled and even having an egg halfway poking out of her nipple, ready to pop out when ready. Her stomach is completely stuffed with eggs to the point that her overinflated belly has reached the ground. Her left breast is being completely stuffed as she feels the warm & slimy tentacle extend and coil its way over and over throughout her breast as the first tentacles travel down its mass and into the safety of her breast.

Here's a list of all the eggs currently within her for those interested in this bit of info. Do note that a lot of the eggs aren't visible because they're behind each other and overlapping:
Intestines: 26 Fertilized Eggs
Left Breast: 1 Coiling Tentacle, 3 Fertilized Eggs
Right Breast: 18 Fertilized Eggs
