Since taking the decision to become her stepson's lover, Stacey was amazed at how quickly the whole arrangement had achieved a sense of normality, how a situation that would have shocked her 6-months before, now seemed the most natural thing in the world. What was more worrying to her was the way in which her relationship with Paul had begun to change, to develop into something she had not expected. At first the idea had seemed simple enough; she would satisfy Paul's needs sexually, at the same time keeping her family together. After all, she would control the frequency & content of their sexual encounters, in no time at all Paul would grow bored of the illicit nature of what they were doing & move on. Right?
Wrong. The spanners in this brilliant plan were her desires, her needs. She craved her stepson like a drug, needed her fix in a bigger dose & more often with every passing day. At first she had limited her visits to Paul to once a week, sneaking in while her husband was out, masturbating him to an orgasm while he stroked her breasts through her blouse. Paul never made any move to take things further, nor did he complain that her visits were not as frequent as he quite obviously would have liked. One thing was certain, his grades had returned to normal, his sunny personality was back, & the black atmosphere that had hung over the house had lifted; in fact everybody who knew him said they had never seen him happier.
For Stacey this was confirmation of her decision, justification for doing what she did. It was also the way in which she explained her need to visit Paul more often; after all, the more she helped him, the better for his welfare. It was with this logic that she began to creep into his bedroom twice a week, why she began to wear loose fitting tops that allowed Paul's hands more freedom to roam over her large breasts, to milk the hard nipples while she jacked his big cock. Soon she was going to his room every other day, usually after Jack had gone to the office, Paul's new alarm clock his step mom's warm hands stroking his morning hard on till it sprayed across the sheets.
The escalation of contact did not serve to cool Paul's ardour; in fact he never seemed to tire of her visits, & it was this enthusiasm that increased Stacey's hunger, the thought that this young stud looked forward to her attentions was the most powerful of flatteries, fanning her desires further. Soon she was going to Paul every day, & after one incident where Paul had 'accidentally' cum on her top, she would now strip to her panties, the fact that her stepson's hungry eyes were captivated by her firm body, left her soaked with excitement. Their love play took on more of a two-way nature as time went on, & now when Stacey would wrap her large tits around Paul's pole of meat, she would rub herself against his leg; his ejaculation when it came, showering her torso with long stings of hot semen, her own orgasm leaving a sticky trail from his knee to his shin.
Although they had done more than this on their first fateful shower together, the build up to more & more exciting games lent the acts more sexual weight. The first time Stacey sucked Paul's hard cock was a rite of passage for them both. Stacey had been giving Paul another tit wank – his favourite position – poling between her large globes, the cream she had made him massage into them making an obscene squelching noise. When he had pushed a little further than usual, his large purple helmet had come to rest against her dry lips, & time had seemed to stop.
Stacey was sitting up in bed while Paul straddled her stomach, so it seemed the most natural thing in the world to let her pink tongue dart forward to catch the bead of pre-cum that was oozing from his large slit. Paul gasped, & pushed his hips forward, smearing more of his fluids across her opening mouth. Stacey was wild with lust, & as she often did, had been holding her panties to one side while her other hand let its fingers do their work on her sopping gash. She quickly placed both hands on Paul's firm butt, pushing his cock toward her open mouth. His helmet was so large she could not get her lips around it with comfort, but instead swirled her tongue around the head. Paul groaned, & pushed further so that Stacey's tongue could make its long wet trail down to his large balls.
'Oh yes baby', he moaned. 'Suck on my big cock.'
Stacey loved to hear him like this. He seemed to be completely in her power. She quickly licked around his sack, sucking one large testicle into her mouth at a time, before kissing back along his thick shaft until his large helmet was again resting on her lips. Paul had both hands resting on the wall above the headboard; his eyes looking down were filled with lust as Stacey used the flat of her tongue to stimulate the sensitive underside of his glans, while the top slid into the roof of her mouth. Saliva dribbled from both sides of her aching lips as she continued to suck as much of him into her hot mouth as she could.
Paul began thrusting with is hips, fucking her willing face. 'That's it mom, suck me, make me cum. I want to shoot all over your beautiful face.'
Stacey was jacking his pole with one hand, the other squeezing his large sack, her middle finger probing at the g-spot just in front of his puckered asshole. She felt his balls begin to tighten, & relinquished her hold on his manhood; roughly pulling aside her panties she shoved three bunched fingers into her streaming slit. Paul was using one hand to wank his bulging prick, & with a roar he pulled his helmet from her mouth & began to shoot large globs of spunk directly into her face. Stacey's eyes rolled back as her orgasm gripped her, relishing the feel of her stepson's hot seed as it covered her face.
From that time it had seemed only natural that Stacey would now suck Paul's cock at every chance; sometimes she would catch him walking out the door to school, dropping to her knees in front of him while his unknowing friends waited in the car, greedily sucking down every drop of his hot cum. One morning while Paul was still asleep she had crept into his room & quietly pulled back the sheet, crawling onto the bed she had begun to nuzzle his semi-hard cock, planting small kisses along its length till it had swelled with blood. Paul had groaned & reached down to cup her heavy breasts as they hung down lusciously, the hard nipples grazing his stomach muscles.
Stacey groaned as his fingers circled her tender tips. 'Squeeze them baby. You know that's what I like.'
Paul obliged, his right hand tugging at each long nipple in turn, making her pant as she licked at his thick cock. So lost was she in her own world of pleasure, that she did not realise he had changed hands, or that while his left continued to squeeze her hot tits, his right was running along the curve of her back. She felt him squeeze her firm ass cheeks & sobbed with desire, her body automatically giving its signals of consent as her gash flooded with moisture. Paul's fingers slipped beneath the elastic of her panties & ran along the tender outer lips of her vagina. Stacey had stopped her own ministrations as with her eyes closed she enjoyed the sensations that rolled across her body.
'Put one in me' she whispered. Paul willingly obliged, slipping his thick middle finger into her hot hole. She moaned long & low. 'Oh god. Oh please don't stop'.
Paul happily took her at her word, & soon he had his three middle fingers sawing in out of his step mom's sopping hole while his broad thumb circled her throbbing clit. Stacey was wild with lust; her hips bucking against his hand, her orgasm rushing at her, she screamed at him to make her cum. Suddenly Paul lifted her by the hips & settled her vagina above his face. Stacey collapsed as she felt the first probing of his tongue. All thought left her mind as her body focussed on the waves of pleasure that came crashing into her brain at Paul's loving ministrations.
Clutching at the sheets of the bed, Stacey stared sightlessly ahead as Paul sucked her clit into his hot mouth; small pinpoints of light seemed to be exploding in front of her eyes like a firework display of pure pleasure. Her orgasm when it finally hit was like a body blow, the intense sensation of her muscles tensing all over her body was like a jolt of electricity, only to be relieved as her pelvis began to spasm forward & with a torrent that Paul happily drank down, her vagina ejaculated her juices all over his face.
