eastwood/aster for an anon- quick centinel anatomy/reproduction lesson in spoilers
Show ContentSpoiler:
centinels have two erogenous zones located at the lower front of their torsos and towards the back end, both of which are extra squishy and almost dough-like when aroused. these areas can be massaged in order to produce a pollen-like substance, which has to be collected en masse and mixed with other parents' in an organic capsule to produce centinel eggs. you'd need a lot of pollen to produce a kid though, and without a proper capsule and at least one other parent's reproductive material, there's no risk of accidental reproduction- so eastwood and aster fooling around before bed here is perfectly safe.
