Caught Cheating on Jack & Junior: Part 1

I just want to comfortably relax with minimal clothing in my own house. Unfortunately, my boyfriend's bro is in town, and he is staying with us. Normally, I don't care if anyone sees me naked including Jack's bro, Junior. Especially since Junior is hot as fuck and we have already hooked up a couple of times since he arrived. I meant to tell Jack, but it just never felt like the right time so I just left it unsaid. I was a little surprised when Jack came to me and asked me to wear more clothes around Junior. He usually likes to show me off! I probably should have told him that Junior has already seen me naked, but he wanted a quick blow job before Junior came back so I focused on keeping Jack happy. I hope he doesn't find out about me and Junior before I get a chance to tell him! I have no idea what he will do!
