She headed straight for her room - but as she passed by Billys bedroom door she heard her son talking to someone. She hadn't expected him to be home from school quite as early as this - maybe something was wrong.

She knocked on the door "Billy are you OK". There was no answer, but now she could quite clearly hera Billy talking.

"Oh yes, I'm fucking you deep, you'se so good - stick your fingers deep into your hot cunt, baby"

Selina was stunned, it was her sons first day at school and he had found someone to bring home and fuck? He was only 14 for Gods sake! She knew he was regularly masturbating - the evidence always appeard in the laundry - but although she was concerned about this it was not as bad as actually having a girl in the room.

She opened the door, not even bothering to knock. But there was only Billy in the room. He was lying back on his bed, naked - cock in hand - pumping his own shaft furiously. He hadn't even heard his mother come in the room.

"Oh, yes he continued "tell me your fucking yourself with that big dildo"

Selina then saw that his computer was on - and Billy was wearing the headphones with the microphone attached. He was talking on-line to somebody.

She looked at her son - she hadn't seem him totally naked like this for years - and it didn't take her long to realise that his cock was even bigger than his fathers, which shocked her since she had always regarded Billy as her little boy".

Billy's prick was huge. Stiffly the long, fat cock meat shaft rose out of his cock curls, at least nine inches long and as thick around as her wrist. The cock knob was as big as a small apple, bloated deep red and glistening with oozing cock cream.

Had she not been so horney from watching the two young performers next door, or had she been having sexually satisfied with her husband she might have left. But the truth was that deep within her she felt a shameful new craving throbbing in her cunt. She had never imagined that seeing her own son's stiff prick would make her pussy feel so wet and hot, but seeing it so soon after the floorshow she had just witnessed just made things worse for her. She fought these deparved feelings.

All right, Billy. Stop it right now!"

Billy raised his head and finally saw that his mother was with him in the room. He sighed, releasing his big cock and and removed his headphones. But he was suprisingly calm. He made no effort to cover his fuck organ, and the giant cockshaft continued to buck and pulse over his stomach. Selina sat beside her teen on the bed, trying not to stare at his cock. She felt her nipples stiffening and poking through the bra and blouse she was wearing.

"Since when did you start barging in on me in my own room?" Billy grumbled. "Can't I even have some privacy?"

"You know perfectly well I was knocking a moment ago. I was worried when you didn't answer. " Selina said defensively, suddenley realising that she was crossing a line with Billy, somewhere that she shouldn't be going. It was time to retreat, she decided.

"You... you could at least pull up your pants when your own mother is talking to you. This is very embarrassing."

Now.... she should leave now. This was so wrong. Billy looked embarrased too, but he still had not made any attempt cover his manhood.

"Mum, you don't understand" replied Billy " That school is full of the most fantastic looking girls I've ever seen - I was walking around with a hard on most of the day. I don't want to stop jacking off now. I need to cum bad!"

Selina was shocked about the way he used this language in front of her. She thought about giving him one of those "wait 'till your father gets home" speeches, she thought about just leaving, but a part of her was so facinated about the brazenness of his actions and the deeply shocking feeling buried deep in her subconscious was letting he know she was getting aroused at her own sons nakedness.

And then he shocked his mother again, sliding his hand down to again tightly grip his giant prick. The astonished mother couldn't help staring at his tremendous cock as he started beating his meat again, slowly and very hard, groaning as he moved his fist up and down the oversized length of his cock.

"Billy! Billy, for God's sake!" Selina gasped at him, overwhelmed with both anger and an irresistible, incestuous lust, knowing that she should leave the room before this went any furthur, but unable to tear herself away "How... how dare you do that in front of me! You take your hand off your prick this instant!"

"I don't want to, Mum. It feels good.Just leave Mum, I'm gonna go crazy if I don't do this.. please understand"

She realised then that he was staring at her... more precicely staring at her chest. She blushed at his gaze, but was still unable to tear herself away. She knew that she was as wet now as she had ever been. She tried to avert her eyes from his prick, but knew she was failing. A deep ache in her wanted so much to touch him, her beautiful son, her darling boy - knowing that it was a forbidden lust only made it worse. She knew he had seen her look at him, and it filled him with courage. She was startting to think all this had been part of a big plan of his.

Billy broke the silence - and when he did it shocked and thrilled her to the core: "Man, you sure have a nice air of tits, Mum. Sometimes I like to think about sucking them when I jerk off. It's even better looking at them at the same time."

"Billy!"

Selina was shocked - but was now losing control. The part of her that wanted her own son, that needed to feel him was winning her over. Before she had reaslised it her hand was filled with the hot stiffness of Billy's prick.

"Ummm, that feels good, Mum! Why don't you rub it for me?"

"Oh God, Forgive me, this is so wrong!"

And then Selina started doing it. She didn't know what had come over her, what had prompted her to begin the worst possible sin with her son. Her pussy was very wet, throbbing so hornily in her panties that she could hardly think straight. She felt overwhelmed by anger at herself, frustration and a wanton, uncontrollable lust.

Billy just lay there, smiling as he submitted to his sex-starved mother's hand job. Selina stared openly at his huge prick now, grimacing as she whipped her right hand up and down the cock stalk as fast as she could.

"Does this feel good? Is this what you want me to do to you, Billy? Your very own mother? You know this is wrong Billy - but it feels so good.Your prick is so big, Billy. Do you want Mummy to suck it too? You'd like that, wouldn't you? You'd like your own mother to put your prick in her mouth and swallow your hot cum!"

Billy had never expected this plan to actually work. He was as nervous as hell, he'd been beating off listening to someone on the computer saying that he was his mummy. For months now he'd been masturbating to the thought of having his Mum do this, and now it had finally come to pass. he could see that his mother was battling with her consiousness, knowing that what she was doing was considered wrong. But he knew now that she was under the spell - if he stopped her now this would proabbbly never happen again. He had to remain confident. Get hthrough this - and the next time would be easier.

"Yeah, that's what I want, all right." he said, trying to sound as in control and in charge as possible. " Why don't you get on your knees right now, Mum? My cock needs a good sucking right away!"

"Oh, Billy, no! ---" but she knew in her heart of hearts she had lost the battle.

And then her words trailed off as she did what her son requested, dropping to her knees in front of him and confronting the huge, aching length of his prick. Selina realized that she was breathing very hard, and that she could feel her heartbeat in her pussy better even than she could feel it in her chest.

She felt as if she'd lost all control of herself, as if it were no longer possible to distinguish between what she was really doing now and what she might have dreamed about. She couldn't believe that she was actually going to shove her own son's cock down her throat and swallow his spewing cum.

Selina wrapped her fingers tightly around his throbbing cock, sliding her fist to the root. She stared intently at the rosy, puffy cock knob for several seconds, seeing how the whole fat crown glistened with sticky spunk. The wanton mother lowered her head, pressing her lips to his piss hole. Shamefully she thrust out her tongue, eagerly licking the tasty cock juice from the tingling tip of his prick.

"Unnggh! That feels good, Mum!" Billy writhed on the edge of the bed, holding her head with both hands. "Put it in your mouth, Mum! Suck it! You know you want to. Unggh, suck it good!"

Selina shut her eyes, trying to block out the knowledge that she was now the kind of mother who gave blow jobs to her very own son. Gradually she let her lips slide onto his pulsing fuck organ, slurping in inch after inch of his giant, throbbing cock. She stopped when she'd inhaled over a third of it, when she would have choked herself if she'd tried to swallow any more of his cock meat.

Then the horny mother started sucking the prick extremely hard, keeping her eyes closed as she nursed contentedly on the aching stiffness of his hard-on.

Selina sucked the tasty cock harder and harder, shocking herself with her eagerness to mouth and slurp her adopted son's prick. She forced her face closer to his hairy crotch base, gagging herself, dying to swallow all of his cock meat in one swallow. The huge prick responded to her hard, wet sucking by growing even bigger and stiffer. The cock knob puffed up obscenely, pulsating on the roof of her gullet.

"Ummlllppp," Selina gurgled.

Her lewd, slurping sounds of cocksucking contentment had become very loud too, filling up the bedroom. Feverishly she started bobbing her head up and down, fucking her mouth with her boy's big prick. Her fingers tightened on the root of his cock. Then she furiously started jacking his prick as she sucked the tip, swirling and basting her tongue around the mushroom-shaped crown, lapping up the salty spunk as it dribbled out of his enormous, aching prick.

"Mum, I'm gonna cum soon!" Billy groaned. "Unggh! I can feel it, Mum! It's really going to be a big one! Oh, suck it, suck me hard! You're such a fantastic cocksucker!"

The shocking, disgusting compliment was music to her ears. Selina felt her face redden as she started sucking cock as hard as she could, rapidly puckering and bellowing her cheeks around the cum-laden stiffness of his cock. Her fist was a blur, whacking up and down his hard-on. She was desperate to nurse a heavy, spurting load out of his cock, to be forced to swallow as fast as she could to gulp down all of her own son's cum.

"Swallow it all, Mum! Cumming, cumming!"

He clutched her head, thrusting his hips off the bed, fucking his cockshaft another inch between her lips. Selina started to gag, but then, at last, her horny cocksucking efforts were finally rewarded. A tremendous shower of spunk blasted out of his swollen cockhead, squirting and splattering down his cum- loving mother's throat.

"Ummmllppp" Selina gurgled.

The cock juice was spewing into her mouth, squirting on her tonsils and running down her throat. Feverishly she clung to the enormous, cream-shooting cock, loving the taste of her young son's seed. Shamefully, the horny mother started sucking, jacking and swallowing all at the same time, not wanting to release her boy's prick until she'd sucked every droplet of salty cream from the crown of his cock meat.

After nearly a half-minute, the cum-explosion was over, and Selina had her belly full of cock juice she'd secretly craved. She raised her head from her adopted son's crotch, dazed and desperately horny, running her tongue around her mouth to lick up the cream. Selina was breathing hard, and her pussy was so wet that it had completely soaked her panty crotch band.

Billy's prick was still very hard, and throbbing in front of her face. Selina's pussy spasmed as she suddenly imagined the huge, fat pussy-pleaser plowing into her hairy cunt slit, ramming deeply in and out her cunt.
