POV: taboo roleplay
i (mommy) enter your room,  as you have just gotten home from your classes.
i am in the process of getting dressed. i explain i am going out with my friends tonight,  so i am going to give you a milking now, as i will be out late. i order you to strip and get in bed....
     ...i sit between your legs. i am giving you compliments and squeezing your penis,  and i am rewarded with an almost instant erection.  i give you an incredible hand job, guiding you to an orgasm. i am rubbing and jerking and caressing your balls and milking  you while telling you how much i love you and you are just about to cum when---

--- what is that? What is THAT??? WHAT THE FUCK IS THAT!?!?!
And i snatch what i see sticking out from under your pillow. It's a pair of MY panties, a pair i was just wearing. i am outraged! Did you sneak into mommys room??? Did you take my personal belongings??? mommy is now FURIOUS!! i inspect them...And what's this??? i look at the crotch.  Is this cum?!? i smell it... THIS IS CUM!!! Sticky gooey cum all over the crotch. 
NOW you are going to learn some manners! If you were a dog, i would shove your nose in it and spank you with a rolled up magazine! If i had caught you with cigarettes i would make you smoke the whole pack! i shove my worn panties back in your face and have you smell my worn panties right in front of me..
    After you smell them, i flip you over and start spanking your ass while venting and voicing all of my frustration.
i am not sure whether i am yelling or spanking the hardest,  but i sure am letting you have it! Thats when i feel your now rock hard dick,  throbbing against my thigh! What is THAT?!!?!
     i flip you back over and see your throbbing hard on. Maybe i should spank just your cock?! Will that teach you some manners?! Is spanking your cock going to get it through to you?! Maybe a rough handjob will teach  you some manners! now i am going to jerk you so hard,  so rough! i start jerking you harder, faster,  squeezing your balls,  telling you how i am going to milk every drop, and you are just about to cum, but then---my phone rings--- 
Who the fuck is call- The school???
oh my god! If you are in trouble at school again, Mommy is going to tear your ass up! she will spank- (switching to my nicest voice) Hello?...
...and everything changes again as i receive compliments and glowing praise about you...,  good grades,  a star athlete,  everyone loves you. It's all the more special because they realize the mother is responsible for all of this,  and now the praise and compliments are about ME! 
     i hang up but am still on cloud nine. i continue the loving, sensual handjob from earlier,  while telling you all of my new feelings. i rethink your stealing my panties. Maybe you just wanted to be close to mommy,  you couldn't control how much you care for me. Mommy understands now, and she's going to take care of you...

...Mommy is lying back on the bed, the crotch of her panties in foreground,  but her beautiful face still in view. On the outside of her panties,  she starts rubbing the outline of her pussy lips, then her slit, then her clit, then the opening of her pussy, then all over again. All on the outside of her panties. All while telling her son how the panties are soaking up the special scent of her pussy. Mommy's pussy...

     ...next i am back sitting between your legs, looking down at you . i peel off my panties and instruct you to sniff them while i finish jerking your dick. As you are sniffing it and i am milking your cock, i tell you that's what mommys pussy smells like.... mommys warm wet pussy.  Can you sticking your dick into Mommy's phat warm pussy? She would squeeze the cum out of it with her juicy cunt!

i jerk you even harder. i instruct you to sniff my panties covered in my pussy scent when you cum, and i finally milk a huge load of sperm out of you!
i immediately lick up your sweet cream.  i tell you to keep these panties under your pillow, and whenever you are missing Mommy, remember i am just a sniff away.
