A PHOTOGRAPHER has captured the moments before, during and after a woman orgasms with an incredibly intimate photo series.

Marcos Alberti's latest work, suitably dubbed "O Project", aims to present female sexuality as it has never been seen before.

To capture the climatic moment of twenty women, he paired up with sex toy company Smile Makers, who believe that being sexually satisfied is the key to being beautiful.

Marcos asked each of his subjects to sit on a stool in front of him and pleasure themselves with one of the brand's products.

He then captured the build up to climax and the moments afterwards.

The resulting photos chart each woman's facial changes - and the speed at which her expression changed.

The photographer has a track record for expertly capturing women in vulnerable and private moments.

Last year he was responsible for '3 Glasses', a series which featured his friends of both sexes being pictured after three glasses of wine.

He said of that project: "“There is a saying about wine that I really like.

"It’s something like this, ‘The first glass of wine is all about the food, the second glass is about love and the third glass is about mayhem’.

"I really wanted to see for myself if that affirmation was in fact true."

Those familiar with that work will recognise that the orgasm photos were taken in the same four-way style.
