nose pinch

Pinching someones nose shut with your fingers, or a tool in order to limit their air supply.

Can be done in an innocent matter fueld by adoration or the lust to tease.

However, little to surprise, it's getting more frequent in porn where the dominant controls the submissive.
I.E. bdsm and breathplay, mostly oralsex in order to gain erotic satisfaction.

Lotte was giving so sweet head, and I couldn't refrain from pinching her cute nose softly!
Mmmh!
That look she gave me, with her nose pinched and her mouth full!
A look of total surrender and trust!
