Here's an Alternative version of

If you decide to use I'd love to see it, you can tag me on Twitter @Salome_Kiyohime, also feel free to hit me up with requests if you'd like! Feel free to send character data too if you'd like!
Made using two max height female miqo'te, and a max height female Elezen though like any pose, could be edited to fit any races, though if the heights are too far apart you might have some issues.
Moreover, I suggest using this pose specifically on the Marble Alcove Bed as that's what the standing participant is posed around, though if you want to use something taller it should be fine, as for shorter it may be a little harder to get their legs right!
Should work with really any penis mod with some adjusting but the specific one I use is
