How to shoot Boudoir client in the poor light and simple room?

I am a Female Boudoir photographer I travelling everywhere and shoot models and clients Boudoir portrait fashion and nude art photography for this session I was shooting in Monterrey Mexico and this lady is not a model but my client, She would love to have some sexy photographs for her boyfriend on his birthday and she's allowed me to video during the shot too, I so appreciate that. For this session the problem is how to give her confidence as a normal lady and never have done the boudoir shoot before and we also never meet in real before also but I talk to her a lot while she get to my house which is we use for the shoot and the room was very poor light by a cloudy day and the room also very simple and nothing interesting, so what we have to do is we need to make her feel relax and confident first then I posed her next to the window and changed some different outfits during that and show her some shots during the shoot to get her some ideas and she will relax with me by connections also and I also talk to her during the shoot all times tell her to pose this way or that way and admired her all the times too like beautiful and nice pose etc..... In the video I not show all of the photos I took because of I need to give some respect for the client about using her photos and its ready great that she allowed me to make this video for my photography youtube The camera I use is this: Sony A7III : https://amzn.to/2A3rG0d Sony Lens 28-70 mm : https://amzn.to/2pO4RYm Follow me more: Instagram: https://www.instagram.com/boudoir_by_ya/ Facebook page: https://www.facebook.com/BoudoirPhotographyByYa/ Website: www.boudoirbyya.com
