I come into your room telling you that I used the family computer and found something concerning: a folder of videos where older women pretend to be the Mom and tell their “son” to masturbate to them. I can’t believe I’m watching porn at all, let alone that stuff. I'm upset and ask why you'd be into such naughty things. Then I see something and pull a pair of my panties from you. I'm shocked and ask why you have them, realising that they are dirty. I ask if you’ve been sniffing them, then if you’ve been masturbating with them. I can’t believe it. I drop the panties and bend down to pick them up, facing away from you and when I stand back up I see you have a boner from seeing my ass bent over and you start rubbing it, I tell you to stop, that wrong this is. I ask why you're like this and you say you find me attractive (mentioning my armpits and butt specifically) and can’t stop thinking of me. I'm taken off guard and while it feels good to be complimented, I say it’s wrong because I'm your mom. I ask if you’ve masturbated with my panties before, you say yes, you like to smell my scent and especially your sweaty dirty asshole on them. I've been getting more turned on as you've complimented me. YI finally sigh and decide the only way for you to see how wrong this is is to replicate the videos. I have you take out your penis, which I notice isn’t very big. As I have you jerk off I undress focusing on a different part of your body (boobs, armpits, ass, asshole) that you're attracted to and what you'd like to do with them. I ask if you’d really want to put you cock in Mommy’s pussy and you say yes. 10 second cum countdown saying “You want to fuck your mommy/lick mommy’s ass/cum in mommy?” Having you repeat “I want to fuck my Mommy”
