New poses are planned. Anything specific you would like to see?
Well the two games are complicated, as they do manual insertions. But with your title the tentacles enter in a fixed position and they aren't attached to walls (right now), so in theory moving her by the ankles/knees, or the like, should be less difficult (I say less, but its still probably very hard).
Or you could focus on only grasping points, where the tentacles physically latch onto wrists/ankles and removing said tentacle, causes her limb to go limp.
