The real details of the teasing was- E is for my Aunt, M is for my mother, and X is for me
E: "Come on now, don't be shy, you're trapped in the corner naked, might as well give up"
X: "I'm not uncovering! How about you turn around and let me go! It's embarassing to be like this"
M: "You certainly aren't embarassed when you talk to me butt naked, what happened now"
X: "Yeah, but I'm not usually naked in front of her (my aunt)
E: "Well you are now, and I'm not letting you go until I have some entertainment, today is a boring day" (not exactly what was said but since it's a local language this was the closest approximation)
X: "Fine, if I uncover for a few seconds , will you let me go? I need to get dressed before anyone else reaches home"
E: "Yeah, but only if I get to take a photo as a souvenir"
I don't remember the next part exactly but eventually I got coaxed into agreeing, followed by this-
X:" Fine, laugh as much as you like" (uncovers)
After laughing a lot, there were a few comments and jokes about me being naked but I only remember two, which are
"You know, your thing (my dick) looks very similar to your cousin (her son, an year younger than me)"
"You look so adorable standing like that, I just have to give you a kiss" (that's when she kissed me on my cheek but followed it up by tickling me on my privates)
I was busy laughing and pleading with her to stop so I don't remember exactly, but I think after like a minute my mom told her to let me go, and they had me pose for the picture and let me go with a smack on each of my buttocks.
I've grown up as the "little kid" of the house in a country that already doesn't give boys a lot of privacy compared to girls, so that lead to me having a variety of incidents like this upto 15, since if you wanted to strip someone for a prank, I was the only viable target (other than my aforementioned cousin)
I haven't had any since then, although there have been a couple that were accidental.
P.s. As you may have noted, the smack on the buttocks is reoccurring. Don't ask me why, I have given up trying to figure out why it happens

. The buttock smack is perhaps the only thing that's done equally to both boys and girls (by females at least, males don't really do it to girls past puberty)
Although of course this is all based on personal experience, and I have seen some of my friend's households where it is quite the opposite, and the girls are more naked, although that is rare.
