Easy to remember.
She sucks.
He goes in.
Devils of Loudun by Aldous Huxley is a book about the nuns of Loudun and Urbain Grandier who was burned at the stake.
These 17th century nuns were visited many times in many nights by incubussses-si.
They had astral sex and blamed it on their parish priest.
Suck vs In vs Celibacy.
