There is a fourth stage worm attack with a fourth worm if you get caught in your supermode/plugsuit. not really lewd, just sits on your shoulder and drains energy.
And to expand on the guy rape animation, its a new debuff you get after cumming a certain number of times (five for me, unsure if it varies) under the hypnosis trap they throw. the text is longer and a darker shade, more purple than the pink debuff they normally hit you with when they start fingering. the trap animations are unchanged under this, but if you collide with any of the soldiers, not just the trap throwers, you'll get the new rape animation.
