B-70B Valkyrie Blk 20

Self-designed, referencing some of Frider user/19138278’s OC designs for the nest
I’ve never learned to draw, so I drew one after seeing all my friends drawing. I probably won’t be able to draw new ones in the future.


B-70B Valkyrie Blk 20 (2)

Original drawings commissioned and some differences drawn by myself, original author Frider user/19138278
B-70B Valkyrie(常服)→ illust/112783206

B-70B Valkyrie bomber in low visibility paint, equipped with Pye Wacket air-to-air missiles.
The exterior uses honeycomb steel panels for structural reinforcement and there is an external fuel cooling circulation system (try to explain).

I will also post some other settings in the last picture later.


エルフレダ · セーンニヤ(艾尔芙蕾妲 · 塞安妮亚) (Elfreda · Senniya)

Self-designed, one of the core characters
Original artist Crowbar Magician user/4577674

The robot, which is composed of Picobot™, a self-replicating robot at the subatomic scale, adjusts the appearance color and simulates the properties of different materials by changing the microstructure. Its main purpose is astringent.

The Separation of Belt and Cage

Artist: Sameme (Hydrangea) user/158758

This work by Sameme depicts CHASTITY President Elfreda Senniya in the official costume of North American representative Ms. Valkyrie, the proponent of the concept of assigning different tags to male and female chastity systems. This work embodies the symposium’s proposals and promotes dialogue on linguistic and cultural aspects related to chastity devices.
Exhibited at the 2023 International Chastity System Terminology Symposium

Due to the delicate terminology required for professional classification, the symposium proposes concise and relevant initiatives suitable for the current stage of art and design. The Symposium recognizes that it is currently impossible to distinguish between male and female chastity systems under the tag #chastity belt. Therefore, #chastity belt will continue to be used as a term to refer to any chastity system, but a more specific term will be introduced to identify female chastity systems. Depending on the symposium initiative, we will add the following tags to all related artwork submissions from now on. This aims to improve accuracy and consistency in this field.
#Bung Chastity Belt: Usually contains an intrusive internal structure and is designed to address an individual’s physiological and psychological needs. This term does not specify whether its internal structure is fixed or not [2].
#Fullbody Chastity Belt: This system includes at least a chastity belt and a chastity bra, which are properly connected. Full-body chastity belts provide full-body coverage and are intended to achieve a wider range of protection and restriction [3].

Additionally, at the symposium, on platforms where tag substring searches are used, if there are other tags that include the string “chastity belt” such as #full body chastity belt, it is recommended to delete #chastity belt. I suggested it.

ヴァルキリーちゃんの飛行前点検 (Valkyrie’s pre-flight inspection)

Each week, Valkyrie will undergo long-distance flight training, including a 24-hour flight that includes two mid-air refueling sessions, and a 30-minute sustained flight at Mach 3.3. It carries inert vibration munitions that are believed to aid flight, at least according to the ground crew.

艾尔(旧活新整) (Al (old life, new life))

A certain mimetic configuration scheme of Al’s that was very commonly used in the past. The sister who once acted as the master lived alone with the master for several years. Of course, she was chained at home most of the time.
Artist: surtr-Computer West user/90937455

The design comes from an old design from 8 years ago, originating from the early exploration of the combination of full-body chastity belts, latex, camouflage and disguised restraints. After that, it went through repeated iterations to form the current El, which also resulted in this old design currently exceeding other subsequent designs in terms of detail. However, because there was no set appearance at the time, and because it was necessary to unify the world view with the current set series, the new design simply used El, which can be said to be a spiritual sequel.

  1. Full body chastity belt:
    It imitates the structure and material of a common full-body chastity belt. Although it does look like an ordinary chastity belt, it cannot be destroyed by any method tried. Other props on the body, including pipes, can also not be destroyed. Additionally, all padlocks, latches, and seams are decorative only and cannot be opened.
  2. Latex clothing:
    Something that has the sheen and feel of latex and even makes sounds when stretched and squeezed like real latex clothing. It is essentially an inseparable part of the skin, but it still makes the wearer continue to feel an unnatural sense of restraint.
  3. Liquid collection device:
    4 liquid storage tanks connected to the leg ring that cannot be removed. The lower outlet can be opened to empty the liquid inside. If the exit is not locked, it will leak, and you or the owner usually need to carry the key to the liquid tank when you are outside for a long time.
  4. Remote-controlled vibrator:
    A vibrator that absorbs and drains fluid from the tubes can turn off the function and allow fluid to accumulate in the body. It can also be used for medicine injection. (It is said that the remote control switch vibrates but in fact it has never been turned off)
  5. Remote control vibrator
  6. Remote control urethral plug:
    Stimulates the urethra through vibration and has excretion control function. It is fixed on the chastity belt and combined with the urethra.
  7. Remote control vibrating beads:
    The default is 50cm long beads, and the size of each sphere can be changed individually. Capable of absorbing intestinal contents and expelling them through the tubes in the chastity belt. It can also be used to control excretion or to inject liquids such as enemas into the body.
  8. Breast vibration/breast pump:
    The breast pump with vibration function fixed on the chastity bra, like other devices, is integrated with the body and cannot be separated, so there will be no situation such as milk leakage. The stimulation brought by this device will not be weakened by the combination with the body. Both the umbrella cover and handle have stimulation functions.
  9. Mechanical prosthetics:
    Similar to chastity belts, they are made of materials similar to stainless steel. Although it was indeed a mechanical structure, it made her feel the presence of her calves and the accompanying lingering feeling of confinement.
  10. Over-the-knee high-heeled boots:
    The boots used to hide the mechanical prosthesis when going out were custom-made with great difficulty. It’s stuffed with cotton and wire to help hold it in place.
  11. Metal frame:
    A small homemade metal frame to help you stand. It is very rough and often falls off. During the initial period of time, I relied on this thing if I needed to walk.

艾尔 (Ayr)

The scene that Al didn’t set was probably a school scene, so naturally there was no plot. I’ve been working on a new character design recently, trying to create something very new.

Special thanks to artist @surtr-Computer West user/90937455 for his creation
