One thing that everyone tells you about being pregnant is that you will experience unnatural cravings.  What few people warn you about is quite how randy you are likely to feel and that, if you are me, your main unnatural craving will be for sex, the harder and dirtier the better.

Drying off after my shower, Tom comes up behind me, put his muscular arms round me and cups my swollen pregnant tits, pinching my nipples gently.  I can feel his penis, big and hard, poking into the soft flesh of my bottom.

"You're so beautiful," he says softly, kissing my neck, "You get sexier every day."

"That's just the novelty of my big tits," I laugh.

"Nonsense," he replies, squeezing my boobs hard, "You've always had big tits, it's just now they'e fucking enormous.  Anyway, I'm after something else"

"Tom, darling..." I find it hard to resist as I feel his finger slip between my buttocks and press against the damp pucker of my anus, "I've got to be at school by 8.30."

"I'll drive you, that gives us at least half an hour," Tom says quickly as he drops to his knees behind me.  I sigh with a mixture of embarrassment (that I am unable to resist his advances) and excitement (at what is about to happen).  Leaning forward and pressing my breasts against the cool glass of the shower cubicle I reach behind to spread the cheeks of my bottom for my boyfriend, lewdly offering him my most intimate orifice.  I feel his breath on my anus and I work the muscular ring to show him how horny I am for his tongue.  I swoon as I feel Tom cover my rosehole with his lips for a delicious anal kiss, his tongue swirling around the prominent ring of muscle that guards the entrance to my back-passage.  I feel my cunt well up with juices as Tom's muscular tongue pushes past my sphincter into my bottom, tasting my forbidden essence.  I cannot resist slipping a couple of fingers into my sopping cunt, spreading the fat lips of my sex in a vain attempt to sate my lust.

I look down between my legs and see that Tom's cock is hugely stiff and pulsing as he eats my butthole, pre-come drooling in viscous strings onto the tiled floor.  His tongue pleasuring my tingling pucker is divine, but I am impatient for his meat.  I need to be buggered.  It is several hours since I last felt my rubbery quoit stretching around his prick, and my bottom is hungry again.

Tom stands up, rubbing his slippery glans up and down the cleft of my furry pussy, parting my succulent cuntlips with the engorged helmet of his cock.  I hear the 'snap' of the lid on the tube of astroglide we keep in the bathroom, and then grunt with pleasure as Tom pushes his slippery finger into my anus, lubing me for the his real entry.  After what seems like an age, it comes, and I moan with delight as I feel the tip of my boyfriend's prick pressing against my arsehole.  Eagerly I bear down with my well-practised anal muscles and his fat cock-head pops past the muscular rim of my anus and into the welcoming heat of my bottom.

With tiny, insistent thrusts, Tom pushes his dick further and further into my back-passage, filling me with his magnificent cock.  I turn to look in the mirror and almost gasp as I see us in profile: my large tits crushed in Tom's hands, my bottom thrust out, my lover's enormous prick disppearing between my rounded buttocks.  The sheer eroticism of the scene causes my anus to spasm and suck Tom's slippery tool further into my shitter.  Finally he bottoms out, my muscular anal ring stretched to its limits around the thick root of his penis, his fat balls resting against the sopping lips of my fanny.

Tom holds me tight against him, squeezing my boobs and kissing my neck as he allows my rectum accomodate his prick.  I can feel his massive sex throb in my rear passage and I feel utterly and deliciously full of cock, completely 'taken'.  I turn my face to the right and Tom searches out my tongue with his own.  We kiss as he begins to bugger me, thrusting his bloated cock lustfully into my bowels.  Nobody buggers me like he does, but even so, I know I will need to be buggered again before the day is out.

Concerned about being late for work, I work my shitting muscles, clamping my ring around Tom's fat prick as it shuttles in and out of my arse, massaging his length with my rectum.  Tom strokes my erect clitoris as he sodomises me, masturbating me to an intense orgasm that reduces my legs to jelly.  I feel damp deep inside as Tom shoots thick volleys of creamy semen into my back-passage, then I work his prick with my bottom as it softens.  I sigh with pleasure once more as Tom again kneels behind me and attacks my tingling pucker with his tongue, eager to taste the sperm he has pumped into my guts.  I reach behind and pull his face in between my buttocks, smothering him with my bottom, and then push his slippery spunk out, shitting it into his mouth.

How I get through the day I do not know, but after I have finished teaching for the day I sit at my desk and I feel that familiar comforting warm fullness deep inside my bowels, accompanied by gentle but insistent cramps that make my pussy throb and swell with warmth and wetness. The pressure is building and I'm chatting on the phone to a colleague at another school. I like knowing that he, at the other end of the line in his sober, dark suit, has no idea that I am slowly reaching under my skirt and starting to gently stroke my tight and sensitive anus. My sphincter is dilating and contracting and it is making me horny to feel my bottom full once again.

I'm bending over now, cradling my belly in my hands and rocking to ease the urge to push. I manage to keep the conversation going while I lick my finger and push it into the ring muscle. The sensation is exquisite and I can't help moaning. 

"Are you OK?" he asks after a little silence. He sounds a little puzzled, worried or is it something else? 

I can feel my firm smooth shit right at my hole now and my office is starting to fill with warm, musky odour. 

"I'm fine" I reply, turning to sit backwards on my chair with my legs wide apart straddling it. I pull off my soaked panties and roll up my skirt so I am naked from the waist down except for my shiny black shoes, but fully clothed from the waist up.

He's asking me why I forgot to post the exam papers he needed. It's urgent he insists. 

"Yes, very urgent, I can't help it," I say with more intensity than is appropriate.  I know what urgency is and I really can't help it.  I've pulled my dripping lips apart and am stroking my erect clitoris, pushing my cunt down into the padded fabric of the office chair.  I can't hold it any longer and hurriedly end the call.

I make my way to the basement of the science block.  It is games this afternoon so I know they will be deserted.  I walk into the girls' toilets and make for the disabled cubicle in the corner.  I have masturbated here before.  The cubicle has its own basin and it is roomy, offering me the opportunity to remove my clothes and really take care of my needs.

It is a wonderful relief to get into the stall and quickly undress. No-one else is in the bathroom, not that I care.  Completely naked now, I touch my prominent nipples until they are as erect as my throbbing clitoris. The pressure in my bowels was continuous, but increasing in waves. Licking my finger and placing it just at the entrance to my anus I can feel a large solid mass. I have been touching my soaking panties all morning, and my lips and clitoris are all swollen and pink.  I play with myself for a while, alternating between stroking my anus and opening it up, and slipping my fingers through my cunt.  My fingers are getting brown and sticky.  I start to moan as the huge turd begins to stretch my anus open further.  I am standing, but bend over with my hands on the wall to support myself. 

I enjoy making lots of noise, groaning with pleasure as the huge solid shit began its slow but inexorable journey out of my hole. There is pain mixed with pleasure, as it is firm and very thick. My anus opens fully and I am flooded with pleasure as my large, firm shit slides out smoothly. Before letting it drop I hold it, half emerged, half still inside me enjoying the stretched feeling of fullness and imagining what I look like from behind. My legs tremble. I sit down and start to rub my clit very fast. As the powerful contractions of my orgasm seize me the obscenely large log slides out of my bottom, 12 inches in all. It falls heavily into the water beneath splashing my buttocks with water.  I stand up a little, squatting over the toilet. I start to piss a thick, gushing stream all over my bowel movement. The relief is intense, I have my finger in my dirty sticky anus which is still tingling from the turd. Finally it's all finished. Tingling all over, my anus pulsating, I sit resting and satisfied.

After washing my hands and bottom carefully, I sit on the toilet in the nude and begin to masturbate, frustrated that once again my back passage is maddeningly empty.  Tom will be away for the weekend, and as I touch myself I wonder which anal toys I will enjoy during his absence.  Then just as I am thinking about my new glass butt-plug, imagining its cool heaviness in my rectum, I notice something, a shadow, out of the corner of my eye. There is a circular hole cut into the wall of the cubicle.  Gingerly I look through the hole into the corresponding boys' cubicle on the other side. 

The boy sitting on the toilet is naked, his coffee coloured skin covered with a sheen of sweat.  One hand reaches up to pinch his small brown nipples while with the other he is masturbating his long, fat penis.  Between his legs a huge pair of pendulous balls hang, brimming with youthful cream.  He stands up and leans against the opposite wall, slowly wanking his monster prick.  I can see his face now and recognise him as Farid, a shy Pakistani boy in my class.  His body is boyish, but sleek and muscular, but for only sixteen his dick is immense: at least ten inches and incredibly thick.  It curves downwards slightly and clear pre-come drips from the engorged glans.

Squatting in front of the glory hole I open my mouth and soon the fat head of Farid's dong is resting on my tongue.  It is an effort to deepthroat him, but I am so greedy for his rigid pole that I manage it and am rewarded with a copious load of boycream that slips silkily down my throat.  To my delight his erection shows no sign of flagging and the emptiness in my bottom is now overwhelming.  I stand up and, pulling my buttocks apart, push my anus up against the hole, eager to be buggered.

I gasp in pleasure as I feel the wet pointed tip of Farid's tongue flicking across the raised ring of brown muscle before pushing insistently into my shithole, buggering me wetly.  My hoop is still relaxed and plaible from voiding myself and Farid has his tongue thrust deep into my bottom, licking the walls of my rectum.  Suddenly I feel his tongue withdraw and feel a hot, wet splat of saliva land stingingly on my brownie.

I groan deep in my sperm-coated throat as Farid thrusts a couple of spit-wet digits into my seething shitpit, stretching the rim of my butthole to prepare me for the buggering he is about to treat me to.  As the fingers slip from my pullulating anus, I hear him lick them greedily, savouring the taste of my shitter, and then feel the blunt tip of his rigid penis press urgently into the core of my slut-hole.  He pushes his meat into my arse without delicacy, forcing his bloated fuck-rod into my bowels.  Perhaps he can sense my sluttish abandon and my desperation to be buggered.  My bottom is about to be satisfied again...
