Return the Favor: Literally

Your mother gives you a wink and reaches underneath her bed. You see her pulling a small cardboard box and she looked like she was about to open it, but stopped suddenly, looking at you. She slides her panties very sensually down her beautiful legs. She playfully raises her legs as she lets them fall to the bed. She picks them up and gently puts them up to your face, covering your eyes like a makeshift blindfold, letting you pick up her scent. You feel her stand up off the bed. You hear the box open, you want to pull the panties off your face but as you reach for them your mother firmly grabs your wrist. Before you can argue she kisses you and stops any attempt to resist. You hear something like buckles being fastened. You wonder what is going on as your mother grabs your cock firmly and licks the head, watching you become aroused again. Finally, you feel her climb onto the bed and make her way up your body. She straddles your chest and strokes your hair. After another brief moment of teasing you, she pulls off the blind fold and you see her looking down at you, gripping the shaft of a black dildo inches from your face. She pulls you carefully by the hair towards her new hard rubber cock. You can't beleive how hard the sight of your mom in a strap-on harness is making you.
"Open up for Mommy, sweetheart."
You obey eagerly, opening your mouth wide and taking the thick toy's thick head past your lips. Your mother slowly feeds you her cock, watching you and playing with one of her her nipples. She is getting so wet from watching you give your first blow job she begins to play with your own cock while she straddles you. You try to take as much of the dildo as you can, but your surprised at just how much of your mouth it fills up. Your mother gets off of you and sits at the edge of the bed. You instinctively slide to the floor as well and position yourself on your knees in front of her. She begins to masturbate the strap-on, already lubricated with your saliva. You crawl closer to her and swallow the dildo, bobbing your head up and down the shaft.
"Mmmm, your such a good little cock sucker."
She throws her head back and moans.
"It's too bad I can't cum inside your mouth and make you lick my cock clean, you naughty little girl."
Hearing your mom call you that makes your cock even harder and you start to play with yourself as you imagine her being able to shoot a hot load of her own down your throat. She thrusts gently in and out of your mouth, letting you get used to the feeling, you have a strange feeling that you will be doing this a lot more in the near future.
"If you really want mommy to help you make this fun little makeover permanent, maybe I'll try and find you a real throbbing cock to suck."
Your not entirely sure how you feel about that idea as you blow your mother, but your so horny at the moment, you doubt you'd turn down any request she makes of you. Come to think of it, you really don't mind the idea of changing your lifestyle. You really think that this might lead to endless amounts of amazing sexual experiences, as your about to explode just from sucking off your mommy's plastic dick.
Gently, your mother pulls away from your mouth and raises your chin so your looking into her deep passionate eyes.
"Well, sweetheart, would you like mommy to make her little boy into her little girl full time?"
