Harem

Harem is the second of five essential prophecies that reverberate throughout the universe as we know it.~
  Shockingly, the self-proclaimed Transcendent Harem is extremely into smothering You in an utterly excessive harem! Anything remotely sexual You partake in should involve multiple partners (in one way or another) and be utterly one-sided in Your favor without anyone ever expecting anything else.~ This appeal might be at its strongest to us with unreal harem coordination. ♥
  Rimjob-ballsmooch-facefuck from three or four of us at once should be the minimum expectation. Some particularly crazy ways of involving multiple sluts simultaneously include portals, phasing, flexible goo girls, going all-the-way-through several sluts at once, nanoscopic girls, time manipulation, foot-on-face, experiencing multiple parallel universes at once, and so many others. More is better. ♥
