Valiantly refuse!

You reach deep down...as deep as you can dig. Somewhere between the cum in your belly and the sticky seed dripping from your ass. You find that spark of manhood, that dying ember, and you stoke it into a fiery furnace.

"Aaaaargh!" You use your postion to your advantage, tackling Mommy and sending her flying back to the bed. You waste no time, lifting her legs over her head like she did yours and quickly leaping around so you can pin her arms with your legs while aiming your cock at her now defenseless sissy cunt. You pant, sweating, fearful any second she will throw you off and make you her bitch...again. But she just lies their, limply.

"Okay, manly man. If it means so much to you, I'll give you one more chance to prove it. Fuck the cum out of me before your lil's sissy clit shoots off in me and I'll let you go on pretending to be a man. But if you cum first, I'm going to fuck you, spank you, and fill your throat as many times as it takes to break you."

You are stunned for a second, but shake it off. You have to do this...you have to prove to her, and to yourself, that you're a man. And besides, you've fucked the cum out of her before, one more time should be easy. You've already cum so much this morning, you should have the edge. All you have to do is slide your big, manly cock in her helpless hole...just get hard as a rock and fuck her stupid...any second now...

"Aww, is my big manly man having trouble getting hard? You can close your eyes and imagine Mommy's fucking you again if that helps. Maybe you could rub your sore ass and remember your spurty spanking? Or you can always suck my on my cock a little, that always gets you hard."

Your Mommy's teasing suggestions have you shamefully hard. You tell yourself it's because you're imagining putting her in her place, but you aren't very convinced. You slide inside her slowly, letting your body weight cause you to sink deeper. You try to ignore how good the soft silky walls of her sissy cunt feel milking you. You are a little relieved it doesn't feel quite as good as you remember from last night, then immediately regretful as you realize that's because it doesn't compare to getting fucked.

"What's the matter, studly buddy? Not as good as you remembered? Wishing you were on the other end of this fuck? Look at the bright side. If you can't cum from fucking my tight, soft cunt, technically that makes you a man."

You appreciate the irony, but ignore your Mommy's transparent attempt to goad you into losing control. You are in charge here. You are going to pace yourself, aim for her sissy g-spot with every thrust, and ignore how expertly she squeezes down on your big, manly cock. It's not easy though...it's like a baby calf nursing. As she picks up the tempo and you feel the first telltale throb, you realize you are falling into her trap! By going slow and steady you are letting her set the pace.

"Nice try SMACK, slut, but I know THWACK some of your SLAP weaknesses too!" You time your plunges with some stinging blows of your own. You figured she knew spanking you would result in your humiliating horniness because she shared the same wanton weakness, and you guessed right. You see her sissy clittly jerk and throb, growing hard and betraying her lust with a drop of precum.

"MMM Not bad, but I have years of OOH training. I can outlast a AAH pent up, practically a virgin like you for MOAN hours." You want to call her bluff, hearing her cries and moans belies her tough talk. You rain down blows faster, blistering her ass while barreling into her balls deep with every forceful thrust.

Your eyes stay locked on her sissy clit, another bead of precum betrays her...she must be close. She has to be...because you are ready to explode. You are biting down on your beestung bottom lip hard enough to draw blood. Your muscles are tensed and taut and you feel like they could snap like an outstretched rubberband. You worry if you don't cum soon you'll have an aneurysm. But you hear her moans, see her throbbing clit...she could blow at any second...

"OOOOH Yessssss harder babyyyy WHIMPER Mommy's sooooOooooOo close!" You realize with seconds to spare the trap you've stepped into. She lulled you into a false sense of security and now she's ready for the killing blow. But she overplayed her hand...she was too eager. Now you know you have to take **** measures.

You reach down and start stroking her swelling sissy shaft, using her own prespurts to lube her up. You stroke her inside and out, focusing solely on making her cum as a way of ignoring how close you are to release yourself. It starts working...Mommy is distracted and even stops milking your cock so expertly. Even better, she is actually stifling whimpers and moans instead of broadcasting them. You feel her pulse quicken in the veins or her clit...you have her right where you want her!

"Hee hee I'm hahaha I'm sorry, I just can't keep a straight face. Sweety, I hate to say it, but you are so bad at this. Your thrusts are shallow and uneven and your strokes have no rythm. You're a pretty decent cocksucker though, maybe that would make me cum before you?"

Your heart sinks. She has been stringing you on all along...playing like she was trying to hide how turned on she was while really just luring you to the edge of a cliff. And now she offers you one last way out...to prove you're a manly man by sucking her clit while fucking her cunt...but this time you are too far gone to care about irony.

You bend over and lift her spongy mushroom head to your mouth, running your your tongue in slobbery spiral around it while closing your plump lips in a tight seal and sucking for dear life. You continue rutting her in shallow thrusts, staying buried inside her so you can remain latched onto her throbbing, tasty Mommy dick. You can feel she's close...for real this time, you can actually taste it, but she is squeezing down on you so seductively...you know this will be down to the wire.

"Fuuuuuuck...I'm going to loooove making you my OOH cocksucking sissy ****! You're going to spend all day AHHH squirming in your silk panties, wondering when Mommy is going to come up MMMM behind you, lift your skirt, bend you over, and MOAN fuck the spurts out of you. Maybe we can invite your WHIMPER friends over to watch...or join in..."

You can't take another second. You try to ignore your Mommy's description of your waking wet nightmare, but it pushes you over the edge, hurtling into the abyss as you fill your Mommy's cunt with hot spurts of surrender. Seconds later she fills your mouth with her own triumphant eruption and you are doubly shamed and sticky as you fall back to the bed, spent and sniffling.

She kneels on the bed and starts stroking herself hard again, using her sissy seed as lube and points to the spot between her legs where your shameful spunk is already leaking out. Defeated, disheartened, you submit meekly. You let her bury your face in her cream filled ass and whimper and moan pathetically as you clean her thoroughly with your all too eager tongue.

"Mmm good at eating ass too...you were born to be a sissy, baby. And now that we've proven it. We need to give you a sissy name. Crawl out from under Mommy's ass, and tell me your REAL name."

You squirm free and look up at her blushing before saying, "Barbie." You are surprised how easily it falls from your lips. You didn't even have to think about it. One more pebble in a mountain of evidence that you truly are a sissy. Still, you hold on to that tiny smoldering coal deep down inside you that says somehow, someway, you will prove you are a man.

In the meantime, your Mommy has a full week planned of proving you wrong...
