Women reveal their wildest fantasies, from becoming a 'hucow' to close encounters with ET

Women have lifted the lid on their wildest sexual fantasies and confessed to wanting to breastfeed men and be 'breeding machines.' 

They opened up about their X-rated desires in a new erotic book curated by Gillian Anderson titled, Want, which hits US shelves on September 17. 

In the saucy tome, the actress and writer collected a series of sensual letters from women around the world who have detailed what they want from their partners.

And they didn't hold back as many admitted they wanted to be a 'hucow' for men to drink their breast milk straight from the source. 

In addition to being 'milked,' women admitted they wanted to get handsy with aliens, have sex with robots, and get off on relieving themselves while wearing diapers. 

However, the concept of being a 'hucow' seemed to be a common desire among women and it even left the author shocked. 

Gillian warned readers of the jaw-dropping admissions that were to come at the beginning of the book as she confessed that she had never heard of getting off on being milked previously. 

She explained: 'I also found fascinating that some women fantasize about being a "hucow," a new term for me (essentially, being milked).'

What followed was a series of notes divulging dirty secrets about being 'milked' and breastfeeding men.

Although the names of the women were kept private, they did reveal some facts about themselves - including their salaries and their locations. 

In a sensationally X-rated letter, one woman revealed that she first started getting turned on by breastfeeding her partner shortly after giving birth - adding that her husband had to 'relieve' her because she had too much milk.

The married woman wrote: 'The other thing that gets me really hot is imagining myself breastfeeding adults, mostly men....

'With my second child I had far too much milk and had to ask my husband to relieve me. I was so engorged it was more a physical relief than a sexual pleasure. But I often return to that memory and make it sexual, or imagine feeding some other cherished person in my life.'

One married woman confessed that her desire was to have a stranger - specifically at a grocery store - suck on her breasts and swallow her milk.

And milking wasn't the only wild fantasy that sent readers into a spin - some women revealed they wanted to have sex with aliens, which Gillian branded 'unexpected.'

Many women confessed that they wanted to go behind closed doors with 'a tentacled alien or a half-human half-beast' or a robot. 

Another single woman - who admitted she was a virgin - revealed that she got turned on by wetting her bed. 

She revealed that she deliberately pees herself once a day and sometimes even puts on diapers. 

She admitted: 'Wetting myself fills me with confidence, but also with the desire to be controlled. It extends beyond just my bed, too. I love to pee in my trousers, skirts, shorts or sometimes just my panties, sometimes in my bed or on the toilet or even in my car!'
