She often found herself looking at him in a way that a mother should not look at her son.  Her gaze sometimes lingered on Mark’s tall muscular body, that he kept in fine physical condition by regular visits to the gym.

Mark was much like his father in physique; only he was about an inch or two taller.  Jenny couldn’t help noticing the similarities between her husband and son.  No doubt about it, her son was a younger and more handsome version of her husband.  She liked her men to be tall and powerful.

Her son was due to go off to university in a month’s time.  Jenny was already finding it difficult to imagine the house without Mark.  No doubt about it, she would miss him during the months of the college term, when he would be away from home.

She was very friendly and affectionate with her son and lavished much of her time on him.  Not that Mark was a mummy’s boy.  He was tough and independent and very definitely had a mind of his own.

Now she watched him as he raked the leaves in the back yard.  It was a warm summer day and he was wearing only a pair of cut-off denims.  Jenny leaned against the window and stared down at him.

She watched fascinated as he worked.  His strong body bending and twisting, as he gathered up the leaves.  Strong and sinuous, flexible, powerful: a real man’s body.

Not for the first time in her life, she imagined him naked.  It was a very pleasurable fantasy, one that she indulged in often, too often.

Every mother loves her son. Jenny loved her tall handsome son in a way that was more emotional that most mothers.  Not only did she love him, she felt turned on by him.  It was a delicious little secret.  A mother’s secret.  Never to be spoken about.

Jenny bit her lip nervously, as she looked down on her son.  He was too damn attractive.  She shivered slightly, as she imagined what it would be like to take him in her arms.  To take him in her arms and feel the heat and power of his strong body, his broad hairy chest, his slim waist.

She breathed out quickly.  Best no to think such thoughts.  She placed her hand on her belly and felt the tightening of her muscles, as a stab of desire shot through her.  No, no.  Mustn’t think about Mark’s strong body, his naked strong body.  Dangerous thoughts for a mother.

She turned away from the window and tried to calm down.  She felt aroused, as she usually did when she gazed for too long at her son Mark.  Her hand drifted down from her belly and rested between her thighs.  For a moment she hesitated, and then quickly snatched her hand away.  Must not. Must not do that.  That would be going too far.  That would be wrong.

To distract herself from her inner turmoil, she busied herself around the house, tidying things that didn’t need tidying, dusting things that were spotlessly clean.

About ten minutes later, her son came upstairs, having finished cleaning the yard.  He headed straight to the shower room.

Jenny watched him enter the shower room and close the door.  She imagined him tearing off his cut-off denims and standing naked under the shower.  The hot water pouring down on him.  His body covered in soapsuds, as he washed himself down.  His naked body all wet and lovely.  Hot water cascading down over his muscled torso.

She shivered with delight.

Then uncontrollable thoughts and images began to flash through her mind.  She imagined herself in the shower with Mark.  She imagined her warm hands slithering over his body, as she washed his naked flesh.  She imagined herself naked, touching and feeling him, her hands sliding over his flesh, feeling his muscles, feeling his body heat.

She shuddered with excitement, as she imagined her hands sliding down his body and grasping his erect cock.

She shook her head trying to get these disturbing images out of her mind.  She returned to her room and closed the door.  Leaning back against the door, she exhaled violently.  It was too disturbing, too exciting.  She mustn’t think thoughts like these.  But she couldn’t control the slight tremor of excitement and the warm feeling in her sex.

She tried to relax.  She rested her head against the back of the door, closing her eyes.  But in her mind, she once against saw images of her naked son in the shower.  What if his hands had slid down his naked body and grasped his cock?  What if he was standing in the shower at this very moment, masturbating?  Jenny shuddered.

She walked away from the door and stood in front of the full-length mirror.  She stared at her reflection.  A mass of blond hair.  A ripe figure with full breasts.  She was wearing only a halter-top and a short summer skirt.  She stared at herself.  Would Mark find her attractive?  Did he find her sexually appealing?  And what if…  What if…  What if he was standing in the shower at this moment, masturbating and thinking about her?

A small gasp of passion escaped from her lips and her hands shot up and clasped her breasts.  She squeezed them, as she thought about her son.  She gasped again, as she felt the shudder of pleasure that flowed though her body, as she squeezed her firm breasts.

Oh no.  Oh no.  Must not do this.  Too hot.  Too passionate.  Too embarrassing.

She heard the door to Mark’s room being slammed shut and realised that he had returned from having his shower.  She relaxed a bit.  No more embarrassing fantasies.  He was now safely in his room.

She smoothed down her skirt and fluffed up her hair.  There!  She was looking presentable.  A nice respectable mother.

Leaving her room, she walked down the hallway past her son’s bedroom.  She paused for a moment and stared at the closed door.  Just a simple door.  That was all that separated her from her son.  He would probably be naked now.  Maybe cooling down a bit after his shower.  Maybe he was lying on top of his bed in the nude, his lovely body restful and relaxed.

She inhaled sharply.  She could just picture Mark lying naked on top of his bed.  It was a wonderful image that filled her mind.

She took a step towards the door and then stopped.  She hesitated.  Jenny felt a twinge of excitement in her pussy, as she stared at the closed door.  How easy it would be to open the door and simply walk in.

She shouldn’t.  She just knew she should not open the door.  It was Mark’s bedroom, his private space.

Her eyes were riveted to the door handle.  Should she grasp it, turn it and open the door?  Should she enter?

No, no, no.

But even as she was telling her self not to, her hand reached out and grasped the door handle.  She turned it.  She pushed the door open.  She stepped inside.

Mark was lying naked on top of his bed, masturbating.

A hiss of excitement escaped from Jenny’s lips.

Mark looked up at his mother, as his hand pumped his huge erect cock.  He didn’t stop.  He just kept on pumping his prick, as his mother stared at him with wide eyes.

She saw his muscular body, his firm torso, his strong legs.  She just couldn’t take her eyes away from his hand, as it pumped on his huge hard-on.

Mark was a young man with enough arrogance not to be embarrassed.  He glanced at his mother and then turned his attention back to his throbbing dick.

Jenny stood still as her son masturbated.

She felt her stomach and pussy muscles tightening with excitement.  She squeezed her legs together.  Her hands slid down her body and clasped her pussy.

She couldn’t control the waves of lust that swept over her.  She stared moaning quietly, as she felt her burning pussy.

Her son’s body stiffened, as he went into orgasm.  He cried aloud as he shot wad after wad of hot spunk out of his throbbing cock.  It shot up and came splattering down all over his naked belly.

Jenny’s pussy exploded.  She couldn’t even muffle her squeal of passion, as her body started to spasm.  She dug her hands in hard against her pussy; as she shook and trembled, wave after wave of orgasm throbbing through her body.

When her orgasm at last subsided, she stood trembling in the middle of her son’s bedroom.  Mark lay sprawled on his bed, his legs wide apart, his belly covered in streaks of white spunk.

Without saying a word, she staggered out of his bedroom, scarcely able to walk, as her whole body throbbed with dangerous pleasure.
