I [22m] caught my [20f] gf with another guy

I’ve always known my gf is a self-admitted “snowbunny”, from hearing her talk about how much she misses getting BBC , so being pretty small and white has always made me jealous. A good example of our sex life is I wear a black strap on in bed over my actual dick anytime we have sex

Recently I saw her phone was left unlocked while she was napping, so went to lock it until I saw that she fell asleep mid-convo with someone. I read the chat against my better judgement and while it started normal quickly changed when I searched by pics only. My heart ached when I saw, she showed him a full view of her nipples then her spread open pussy minutes after

I kept looking and found a folder of them together in an off brand cloud he had sent her the link to, showing me her irl with him making what’s basically their own porn gallery. Instead of being mad without thinking I sent myself as many copies as I could and put her phone back. I jacked off the whole time she was out with “friends” that night as I had seen him ask her in one of their recent texts to not wear panties under her skirt and she agreed.

When she got home asked if we could have sex for once. She actually would take my offer up, just getting on my lap and sliding it in since there was nothing on under. I couldn’t feel a thing, and she just giggled about “this is why you wear a toy”. I came incredibly fast in her after already having been edging, even if she felt incredibly loose to me.

I told her what I saw and she just told me to ask her for a link next time in a joking voice. She did actually apologize for not telling me, as she felt like I could be a cuck due to being so submissive with her but not sure, so she was waiting to mention it.

I agreed to try being cucked openly as it’s her biggest fetish/kink if she agreed to play into one of mine. I love her legs so she now wears my fav shorts/skirts/heels at home, wraps them around me constantly, and lets me feel them up to cum on her thighs. In exchange for me getting no say in her regularly getting BBC in our bed going out hook up with any guys she wants.
