Entity

An entity that has no substance or form lands on Earth after traveling among planets and stars. It happens to land in the hair of a gay man, accompanying him into his apartment and his life, where the entity becomes so enamored of an old Royal typewriter that it splits in two.

Though unable to speak, the entities learn language because the man is a writer. They also learn about sex because he writes porn. Observing the man with a male lover, the entities are fascinated and ultimately crave sex for themselves. Can an entity without form or substance manage to have sex?
