<human>: My boyfriend is a photographer and he has a weird thing going on with one of the girls he regularly works with. She's a model and I believe the first time they worked together it was for a fashion shoot but since then she's been she's been commissioning him to take pics of her for her blog/insta. He's been shooting her *a lot* lately and the pics have gotten increasingly racy (as in she only has panties on in the latest set), it almost looks like a porn shoot.

I try to be very trusting because I used to model too so I know how it goes but I can't help but wonder if something else is going on. She was over at our place looking at some of the pictures yesterday and for like an hour she scratched his back as they went through them. Then today she posted a pic of her kissing his cheek with the caption "this guy 😍". I've asked him a few times if anything is going on between then and he says no, he just likes shooting her because she is easy to work with and its great exposure because she has a huge following but if they aren't even posting the latest pics, what is the point? Also I'm 99% sure she isn't paying him but I don't want to ask because I guess its not really my business, but he is an amazing photographer and is quite busy and turns down a ton of work but will shoot her either for free or for very cheap.

Does it sound like he might be cheating on me or something else could be going on? Or am I just being jealous?

Can you give me the gist of the text in a nutshell?
<bot>: My boyfriend shoots this model alllllllll the time and I'm starting to think there may be more going on.
