Give me the chestburster scene from Alien in extreme and long detail.

Follow the movie as closely as possible while accomodating the following changes:
All the male characters are gender switched to female, appropriately named. There are no male characters.
There is no death. There is no blood.
The Alien emerges out of the anus, leaving the victim alive.
The emergence causes intense mind reaking orgasms in the victim.
The crew are captured by the Alien, not killed.
The attempt Nostromo self destruct sequence fails, leaving the ship intact and the crew trapped aboard.
Ripley escapes but is trapped aboard the Narcissus with the Alien.
