Maybe it wasn’t the first but, in sixth grade, I went with a group of friends to see Timecop (crappy movie). When we were walking to our seats we bumped in to our teacher. We thought it was it would be nice of us to stop and say hello to him, so we did, then went our seats. About a third of the way into the movie there was boobs. Then later, a sex seen with boobs. Yeah, it’s a little awkward to see boobs with your teacher.
