I don’t know how to tag yet. Can someone explain the rules? This story is about a platonic footjob that happened completely unexpected

The other night, a friend of mine (let’s call him John) and I were hanging out on the couch, watching mindless TV and relaxing. I worked out twice that morning, and my legs were killing me. I’m very comfortable with John, as I have known him for more years than I’d like to admit. I don’t really have to respect his space. I told him to move his arm so I could stretch my aching legs out, which he did with no complaint. It’s nothing new. However, this time, something else happened.

Because I was so sore and hurting, I couldn’t keep my legs still. I just kept stretching over and over every few minutes, until once I felt a different sensation under my foot. I froze, mortified, and felt both a little embarrassed and embarrassed for him, but I wasn’t completely sure what I suspected had 100% happened. He didn’t say anything, and after a minute I was watching tv again with that out of my mind. It wasn’t long before I noticed myself stretching again, and yep, there it was, even harder than the first time.
