GF sending black friend lingerie pictures. [Cuckold] update 4

Update on my situation, 2 previous  post https://www.reddit.com/r/cuckoldstories2/s/otWLq5Ae54

My GF was sucking me off in the living room, it was getting so intense, I insisted we take it upstairs her phone was on the coffee table next to me bare in mind I've not gone through her phone for the 5 years I've been with her. 

I was shocked at what I found on one of her socials the black friend of hers she met at the hotel. She sent him sexy lingerie pictures of her in red lingerie which she only sent to me. and many other one. A few years back I asked her did you ever send him lingerie pictures of yourself she said no so I was taken back what i found this made me so horny.

I went up to the bedroom & she was laying there in a green lounge lingerie she looked so sexy, I fucked her her so good, all I could think about was her sending those pictures to him.

Do you think I should confront her, but I also wanna dig deeper into her phone an find more sexy things.
