A cursemark of unknown origin that appears as a black ace of spades mark on the skin, which shows through fur. While inactive, the mark remains black. When activated, it will begin to glow. This glow shows through any coverings.

While the mark glows pink, the curse bearer's clothing becomes a revealing, skimpy version of itself, which often includes various sex toys and complete exposure of the victim's genitals. Changing clothes does not disperse the effect, as the clothes revert to normal when removed and any new clothes put on will be immediately skimpified, but the curse bearer is spared any longterm consequences for being in public in such revealing clothing.

When the mark glows blue it summons dark skinned humans who will immediately molest and rape the victim. These events nearly always have some element of the supernatural to them (as the assailants appear from nowhere) but can otherwise range from mundane attackers to untouchable assailants who are only visible in mirrors. The clothing skimpification effects are sometimes maintained while this effect is in play.

The mark will activate seemingly at random, but is far more likely to activate while the victim is in public or in a compromising position.

The mark is contagious, spreading to other victims if they remain in the bearer's vicinity. The mark can dissipate, but it is completely unknown how one can cause it to dissipate, and it seems to do so at random. It is known, however, that the victim's mental fortitude weakening and breaking with repeated activations will have the opposite effect, causing the mark to grow larger overtime and activate with greater frequency and intensity.
