Grimace

A grimace (as explained in a video by You tubers Weasel Horizon) is the act of penetrating a females anus with a dildo (preferably a purple one) with out any lubrication. The act will cause the woman to grimace.

Karin started to fuck Ami in the ass with that purple dildo during the orgy but forgot the lube.
