The combination of a「willingness to comply」(甘) with「concealed copulation」(匸, 儿, 匹) will likely result in some INTENSE and EXTREME actions, as may「a given, easily possible option」with「hanged, tied.」While not entirely obvious in the modern form, the old glyphs seem to combine「smiling sweetness, willingness to comply」and「concealed squatting copulation」or「contained and lame, cannot flee」as a reference to INTENSE and EXTREME actions of sex (performed with the aid of a cauldron perhaps). Elements may also be a merging of「prepubescent girl arrayed as a fleshpot」(卝, 旦, 貝, 一, 具), or the「sweetness of copulating unseen and hidden, to death.」
　「Concealed squatting with bent legs, counter for animals」might have something to do with the intensity of performing activities while「squatting with bent legs, concealed from others, as a herd asset」(lower element) or with ewes, ovine zooerastia, tup-tup schtup-schtup. May be a depiction of initially consensual sex among a young girl and adult male that may have taken a nasty turn after the bondage started, or, no one could hear the bleating of the ewe lamb as it cried out begging to be rescued.
　INTENSE is derived from the nonstop, EXCEEDINGLY EXTREME rabbit-style, machine gun-like EXCESSIVE copulatory actions,「concealed squatting with bent legs possessing what is now mine, that willing, smiling fleshpot…」Note that a bondage scene of a ewe or young girl tied to a fleshpot is the stuff some dreams and fantasies were made of (in the old days of China: see related glyphs 夢, 瞢, 夣) that result in the INTENSE THRUSTING actions associated with rabbit copulation (lower element 匹 is used as a counter for several species of small furry animals, such as bunny rabbits and ewe) that could easily become TORMENT while bound in a physical position of bondage that also would enable TEASING of all sorts,「leering at young girl or ewe vagina tied to fleshpot at extremely close range」to torment the poor animal, or the young human of course.
