And here we have the naughty little minx Queen Motherly Morning who (in my headcanon) is the most sultry of all the fusions)  
Running the crystal empire is no easy feat and can be tiresome even for an ever radiant alicorn comprised of three bundles of energy in the elements of RD AJ and Pinkie and a little spark of Sunset to make it all complete (see what i did there no? well ok)
 
Anyway… a mare needs to unwind in whatever way suits her the most and for MM’s case it is taking her vents out behind closed doors with her hunk of a hubby King Calm Merriment. The poor boy can barely keep up with her ‘needs’ shall we say and he is always apprehensive of what naughty plot (in more ways than one) she has in store for him this time, always being on his toes around her (if ponies had them) as if they were teenage ponies again, which leads to the most electifying chemistry between them which can be seen a mile away, which is a bit of a running joke between the royal guard staff as many a time she is caught giving him a seductive glance or less subtly, the back end end of Calm Merriment can be seen pulled magically towards their private chambers.
 
Motherly swears by the endorphins she receives from her hubby to charge her up for another day of radiating sheer joy and happiness throughout the kingdom
