Humiliating Myself To Mom

I once had my mom sit on the bed while I got completely undressed and then got down on my knees on the floor in front of her and started masturbating. I made ahegao faces, squealed at her like a little girl and said things like, 'I'm still a virgin who's never even touched a girl's body before' and 'what does a vagina feel like? I wanna put my wee wee inside!'
She tried to keep a straight face but ended up laughing hysterically at me and calling me a pervert as I came in front of her from the humiliation of it all which made her laugh even harder, worst of all she recorded it on her phone and has made memes of my face making those faces and keeps showing it to me from time to time.

Now when I see her in normal situations around the house with other family members around she'll sometimes stare at me then to my groin and back to my face again and smirk at me. As if to say I know exactly what you look like 'down there' and what you did in front of me and I have it all recorded on my phone.
