It's different now than when it happened.
I've only been spanked once, as an adult. I've written about it on Zity before but basically it was a female friend, not a girlfriend, who I asked if she would spank me. I was going through some hard times and felt an overwhelming urge, a need to release something, and as she was listening to me yell and cry she said 'what can I do to help you?', and I just blurted out 'SPANK ME, PLEASE'. I just had this sudden urge to be punished, to feel pain, and she is my most trusted platonic friend. She didn't flinch, she just said 'ok'. I laid down, pulled my pants down, and said 'do 10 please, HARD, I want to feel it.' So she slowly spanked me 10 times, bare hand on bare bottom, very very hard, and it really did hurt and did feel good and cathartic. After we hugged for a long time and I thanked her and we've never spoken of it again.
So at the time, my head was really messed up and I seriously needed that punishment and it honestly did help. It wasn't exciting, it was an emotional release.
But now years later, when I think about it, in some ways I cannot believe I asked my dear friend to do that and that she agreed and that she did it. I mean, usually friends do not do this kind of thing with each other, especially exposing a private part of the body. I could never ever tell her this but there are times looking back when the thought of it excited me, imagining the scene of my lying facedown and her looking at and spanking my bare cheeks. I must admit that if a video of it existed, I would watch it. Of course because my pants and underwear were only down to my thighs, my legs were closed tight together so it's not like she saw anything else, anything more intimate.
Part of me wonders if she enjoyed it, seeing me like that, or spanking me like that. I wonder if she ever thinks about it. Again, I'll never ask her. It's too valuable a friendship to risk it.
