"Oh, the SINFUL bit is yet to come, Mommy", she giggles, her eyes gleaming a bit evilly. "Now get that cock in your mouth: NOW!"
I can't help the wanton moan that hisses out of me as I lean forward and obey my dominant offspring, my mind flashing back to the activities of this morning when the teenager I imaged so innocent (she still watches 'SpongeBob Squarepants, for heaven's sake!) penetrated my mouth, my fanny and Lord forgive me my BOTTOM before departing from school; hot shame flames my cheek as I open my mouth wide and swallow the apricot sized tip of her wicked penis.
She urges me on ('There it is, Mommy...there's my slut from this morning!' and 'Those full pretty lips of yours were made to suck my cock, Mommy-kins!') and I no longer care; I CAN'T care at this point-all of my concentration is focused on pleasing my Mistress: on fellating her to her satisfaction. I swirl my tongue about the underside of the ridged crown, a technique I learned during my bachelorette days (and after, with Sara's Dad). Pleasure races through me, but it SHOULDN'T...I'm preparing a rubber dick wielded by my OWN CHILD to penetrate the possibly weeping gash between my thighs but CERTAINLY my arse...I should be mortified, and I'm not...I tell myself that it isn't ME who wants it, it's SARA-SHE'S the one who's shown a marked preference for my big juicy and round behind.
I moan like a back-alley strumpet; I can barely believe that this is actually happening. I'm being driven mad by Sara and her blasted evil desires. "Lord, help me!" I blubber (rather ridiculously), drool dripping from my dildo-stuffed maw. I use one hand to cup the big sack of apple-sized 'testes' clustered beneath the base of the cock; the portion buried within her wet gash shunts a bit as I bob my head rapidly upon the business end of the shaft and I hear a satisfied gasp from Sara, which warms my Mother's soul.
"Enough, Mommy...get on all fours." I squirm my arms around to reach the zipper on the back of my dress and Sara orders "NO...leave it on."
I place my hands on the carpet and arch my back; when she shucks the hem of my dress up over my plentiful, garter-belted hips I whimper "Lord in heaven"; the economy-sized contraption slaps against my left buttock and I can feel it ripple and dance like jello. We're both going to hell I say to myself when she peels my big buttocks apart and buries her gamin face between them.
Soon, I feet her weight on my back, her groin molding into the space between my splayed cheeks, the full length of her buried deep inside me...stretching me...fulfilling me. In and out she thrusts, hands sliding under to cup and squeeze my EE cup boobage. Enslaved by her lust, all I can do is groan and squeal, surrendering my squirming bowels to her rampant rutting. I lose track of time; all that I'm certain of is that I have never been this stretched, this wanton, this GAPED-OPEN. "This isn't FAIR!" I howl, as Sara's machine-like plundering of my bottom wrings yet another orgasm from me. "Oh, Lord, how did this happen?" I sob, jolting forward from the force of her ingresses. "Why did you give me such a wicked daughter?!!"
