My friends jerk off to me [22F] together but they have no idea I know

So about six months ago I was hanging out with my boyfriend and he was showing me a video on his phone when a notification popped up. It was a text from another guy I knew and I saw my name. So I forced my boyfriend to give me his phone. It was a group chat with four guys (all people I knew) and it was a group chat where they shared girls’ pics and talked about them pretty sexually. I even saw some porn clips in their media. They shared pics exes, celebrities, girlfriends, random pics of girls they found online etc.

I read texts from when they talked about me and it was basically my boyfriend bragging about fucking me and giving them details and his friends talking about how they wanted to fuck me and what they would do to me. Sometimes they even talked about jerking off and cumming looking at my pics. I never send any nudes but basically every pic I sent my boyfriend was there. He told me this is a common thing guys do and we had a fight but I calmed down after a few days.

Also one thing to know about me is, I take a lot of pics and I send a lot of them to my boyfriend. I take outfit pics before I leave the house, I take mirror selfies whenever I see a mirror, whenever I get new clothes I try them on and ask his opinion, I ask him to choose from pics I take for instagram, I send him random selfies when I get bored during the day, I send progress pics before I leave the gym… So basically a lot of pics.

After I calmed down I started thinking about it and I kinda made me horny. So I made a deal with my boyfriend and started sending him spicier pics, on condition that I’m there when he shares them and I get to read all the texts. I started sending him pics in my underwear, half naked out the shower, pics with sexy poses and recently even started sending nudes. Every few days I get horny and we send them to his group chat and read the guys’ reactions together. I love it, it became a new kink for me and every time I get so horny we end up having sex. I jerked him off while reading the texts, gave him blowjobs and even made him go down on me while I kept reading. Then we just drop the phone and he fucks me.

Any ideas what I should do next or should I know where to stop?
