When I got a spanking at home, it was over my father's knee, with my jeans down but my underwear still in place, thank goodness. My sister liked to watch, but Dad would usually tell her to get lost.
I got spanked by my aunt, once, when I was about six or seven, and I remember being shocked when she told me to pull down my jeans *and* my underwear.
There I was, jeans and briefs around my ankles, and my little cock dangling, and she sat down and pulled me over her lap with my genitals pressed against her bare leg (she was wearing shorts.) Needless to say, I was very embarrassed to have my bare bottom open to her full inspection, and my privates against her bare skin.
I was even more embarrassed when she put her right hand on my hips and held it there for a few moments, then gave me a little pat or two before she began the spanking proper.
I had never been spanked that way by either of my parents, and I honestly don't think my aunt realized how inappropriate it was for her to do that... or even, that she was enjoying it in any way other than the satisfaction of teaching a 'naughty' boy a lesson.
At least my cousins didn't get to watch.
One of my friends told me that after his mother gave him bare-bottom spankings, she would smooth cream over his rear and elsewhere.
When I was over at his house, I found myself wondering what it would be like for *me* to get a bare-bottomed spanking from his mom, and to feel her hands smoothing on the cream, afterward. But I never found out.
I would still like to try this with my better half, sometime, but I'm not sure what she would make of all this, if I asked her.
