Grace sucks (chokes on) the ovipositor comic (Patreon)

Ovipositor headcanons:

Rocky has good gross motor control but not fine motor skills

can be inflated, stretched and retracted, coils into his body and fills/expands when he's ready to mate

Rocky's obsessed with the soft "plap" sound of it slapping Grace's face, Grace is not a fan

Coated in mercury inside the suit but Rocky made a special lubricant just for Grace because romance is alive

This was Grace's idea
