Original Chinese meaning of MAKING AN ABRUPT SWIFT MOVEMENT TO CHANGE VECTORS and CONSPIRING to use a「rod for penetration into a different orifice juxtaposed」with the previously stated goal seems to not only need no further explanation, but also, to have been a fairly common norm practiced within all human societies throughout the ages, including those of today. Moreover, penetration into one and then the other orifice, directed without apparent purpose during a mix-up as the glyph depicts, aids with lubricity and contributes to acquiescence.
Some have insisted that this glyph can only be referring to SKEWERED MEAT being heated, but if so, one cannot deny these elements are then「multiple orifices pierced with rod」one after the other, obviously while sizzling, such as might be found skewered and in heat cooking on a spit (popping with bursts of burning hot fluids emanating from the meat chunks)…see Used-In glyphs of a 'chronically ill patient with fever' (患), 'unknown source, indecipherable' (漶), 'earn a profit while enjoying yourself' (贃).
External source-given meanings, while considering how a feudal lord would have probably behaved within his harem of concubines, lead one to conclude this glyph is most likely intended as two connected (中) elements as they would begin to form a BUNCHED CLUSTER (束), or, MOVE FROM ONE TO THE NEXT. Certainly, other animal primates, elephants, bears, moose, dolphins, lions, horses, gorillas and many other species in addition to human feudal lords behave exactly in this manner. Perhaps an ordinary male without a harem might CONSPIRE to behave similarly, if at all possible, STRINGING TOGETHER, 'skewering pieces of meat.'
Interestingly, this glyph also included one's RELATIVES in the old days as a fairly clear reference either to incest, or to cannibalism, or to both perhaps, but today that may include someone asking around for a loan among extended family members. The English words cluster and clyster both formerly referred to enemata anal irrigation: Middle English clister, from Old French clistere, from Latin clyster, from Greek klustēr, kluzein, to wash out [ https://www.thefreedictionary.com/clyster 2015-09-04 ]
