Lamashtu

Lamashtu are a variation on the Lilitu found on page 94 of GURPS Horror. Two key things worth noting:
*Rather than steal children’s breath, she gave them poisoned milk in the night – not owing to dependency or need, but merely out of cruelty.
*In some versions, she also poisons those with whom she has sex.
One or both of these appear to be reflected in Toxic Attack.
It has Blood Agent and Cyclic and Onset 1 minute after a set up of Preparation Required of 1 minute.
The thing about that is it doesn't specify the means of attack. It likely is not meant to be the traditional places where innate attacks come from such as eyes (gaze) or mouth (breath) or hand (beam).
Specifics are not given but presumably for poisoning babies it would be the breast, with the Lamashtu acting like a supplementary nursemaid.
That could also be the means of delivery for the sex-users, in which case it is not actual sex but rather foreplay which delivers it to a victim.
This differs from another sexual attack on H66 by the Succubus which uses Contact Agent with requires sexual intimacy as a special accessibility
