Brazilian photographer Marcos Alberti has teamed up with sex toy brand Smile Makers to capture twenty women as before, during and after they orgasm in an intimate new photo series

This 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.
