Incredible

Yeah, seems to be Alyssia Kent from this scene, thanks mate

What's her name?

I believe that's Suki Sin iirc

Oppai = boobs

I'm not sure who the other two girls are, but definitely not Hitomi

Sorry for the late reply, I've appointed @AlphaBetaGammaTheta@lemmynsfw.com as a mod of !anriokita@lemmynsfw.com

Autumn Falls I believe

Fr, she demonstrates it in an interview (YT link) where her she mentions breasts have grown to 8-10kg and is still able to do it.

Assuming this was taken professionally, they would have tents on site with blankets, hot drinks, anything to warm up between shoots which themselves would be done as quickly as possible. Kate Upton did an Antarctica photoshoot with the behind the scenes on YT: https://www.youtube.com/watch?v=IrBpc0766vs kinda impressive how much work goes into it.

Other than that, if it's ameteur, I hope they prepared properly lol
