Walked in on my 17 year old daughter having sex..

My 17 year old daughter is in college but comes home like every weekend. She brought her boyfriend with her because we've only met him like once. Her dad and I left the house because we like to smoke marijuana but we keep it away from the kids. I come back and open the bathroom door (She told me later she locked the door but I definitely should have let her know the lock is broken) and there's her and her boyfriend in the shower. I closed the door, walked downstairs, and yelled at her to get her ass downstairs now. She comes down looking like a scared little girl while me and her dad stand there with our arms folded. Her boyfriend trailed behind her shaking. I started to tell her off but her dad stopped me. He said "Remember when she caught us in her car and we were supposed to be cleaning it out for her? Think of this as an eye for an eye moment." It got silent for a second until everyone started eventually giggling. My daughter said ew dad don't remind me and he said "I'm not reminding you, I'm reminding her" Superbowl Sunday is off to a great start. Just a GREAT start. 😂
