Punishment underwear

Punishment underwear are articles of clothing used in the Rejuve Universe that are used to punish children (particularly through either pain or embarrassment.

Pain-ties and Bee-riefs
Essentially the same thing, Pain-ties and bee-riefs are cotton under made respectively for young girls and young boys that are intentionally uncomfortable to wear. Looking very similar, with the exception of extra space in the front of the bee-riefs and some verions of pain-ties have frills, both types of underwear are designed to have loose threads stitched into the section of cloth covering the buttoms. These long threads (called biters) rub against the buttocks the the wearer moves and while only mildly uncomfortable on an un-spanked bottom they can scratch and sting a well spanked bottom.

Canonically in the Melody Stories there are four degrees of Paint-ties/Bee-riefs with each level having clearer designs and a different colour so that witnesses can see exactly what kind of underwear is being worn Trans-scripted from Melody Stories:Melody's Xmas.''(Next was Granma's present. Melody opened the box to find a full set of four "Pain-ties™" These thickish little-girl panties were specifically designed for well-spanked bottoms. Have you ever been stuck by the end of a nylon thread in your clothing?? Pain-ties were DESIGNED to have such threads in them...in the area covering the bottom. These were called 'biters' colloquially. The first pair had only a few such threads. They were the thinnest pair, looking like regular plain yellow cotton panties. But when worn, every so often a thread in the bottom area would stick, causing a brief fiery sting. Sitting on them, (in the corner, for example), would cause more frequent stings as the child's own weight pressed the special fabric into her bottom. The next pair were pink, covered in a pattern of small hairbrushes and paddles. These were small enough to only be recognizable at close range, so the panties could be worn without being TOO obvious. It held about twice the density of 'biters' as the first pair, resulting in more frequent sticks. The third pair was white with a pattern of rosy red bare bottoms on it. These were designed to be obvious; even if worn under a short skirt, anybody could tell a child was wearing Pain-ties. The density of biters was about the same as the yellow pair, but the threads were designed to be a bit longer, imparting a fiercer sting. The last pair weren't really panties at all, as they extended right down the thighs halfway to the knee. The back of these panties had a single design; a well spanked bare bottom painted right over the appropriate area, with the spanking carried on down both legs. These would be obvious under ANY kind of dress less than knee length. The density of 'biters' (type 2) was higher, too, and covered not only the bottom but also the upper thighs.)'' ; however discrete versions are available too.
 * Level I : Low density of threads, Thin, they resemble regular plain yellow cotton panties/briefs.
 * Level II : Twice as many biters as level one, pink (blue for boys) covered in a pattern of small hairbrushes and paddles.
 * Level III : Same number of biters as level two but longer. White with a pattern of rosy red bare bottoms on it.
 * Level IV : Designed like boxer-briefs with level 3 biters on the area covering the back of the thighs. Depicts a well spanked bare bottom painted right over the appropriate areas.

Nappies or Diapers
Perhaps the oldest form of embarrassment, Nappies or Diapers are an absorbent form of underwear that is typically used on infants and toddlers who have yet to gain control over their bladders or bowels.

Even though absorbent shorts or boy-brief 'Pull ups' exist that don't look like toddler-wear, in the context of the rejuve universe children as old as 10 can be made to wear childish looking nappies/diapers that look just like the toddler versions. Some can even have childish designs on the bottom and by forcing the child to wear Punishment clothes it is possible to draw full attention to the fact the child is wearing them and to increase the embarrassment as much as possible.
