Back in college I had one of those great low-effort on campus jobs in the student union. Basically all I had to do was walk around the building every couple hours and make sure it’s still there. Every now and then we’d set up or take down some AV stuff. Tons of downtime. My coworker Annie and I often worked overlapping shifts and we got along pretty well.
Like most college kids, we had hormones. Those hormones would often spur us to talk and tease about sexual things. She’d brag to me about whatever sexual conquest she had last weekend, I would (jokingly) brag about my size, etc. We’re both very sarcastic and could play off each other for hours with that style of humor. One time we were walking down a hallway and she abruptly stopped in front of me and her hand swung backwards right into my crotch. I joked that if she wanted to get her hands on it, she can just ask. That kind of teasing.
