If you have no idea how to do this but convinced her to shoot full nude, that tells me you're 100% in this just to see her tits. Don't be a Guy With a Camera.
Posing, study the classics, Helmut Newton, Bunny Yeager and Richard Avedon. Use light to your advantage, no one likes shitty indoor hotel lighting. Project shadows onto her like that one guy in the 1940s pic related I can't remember his name but someone here knows, he shot his wife and projected all kinds of shadows onto her while she was nude shit looked cool. I've done it with lace linens and shawls with patterns on them.
Use candle light if you have fast enough lenses, girls love that moody lighting shit. Don't shoot innawoods nude, every horny gooner with a camera does that.
Don't be going in trying to fuck. Don't think with your dick, go rub one out before you shoot. You're here to make art, not be a fucking creep. Wanna do this again later on? Don't be a fucking creep and don't get all touchy feely and shit. Don't listen to the gooners on here with Stage 4 terminal autism who are going to come in here and tell me I'm wrong, most of them are compound-turbo nitromethane virgins who have never shot full nude and think porn is real. You're not Terry Richardson, don't be a fucking creep.
Sounds like you got some cool shit planned, we wanna see the results.
