How many times do I have to tell you to knock on doors before entering?

After Sheila returned home from work, she found herself staring at pictures of her family while sitting on a couch alone. A picture of her young son and another picture of herself smiling beside her husband, who was carrying him, standing in front of a fountain.

When she saw those pictures, a sudden pang of guilt hit her in the heart. She felt ashamed of cheating on her husband multiple times behind his back. Even though she had done it for years, she never felt as bad as today.

It wasn't that she disliked her husband or that she hated sex with him. But somewhere in her heart, she knew that he wasn't able to satisfy her fully. Even though they had a lot of lovemaking sessions, most of them were boring compared to what she had with random men.

Her husband lacked the passion and roughness she craved. Maybe it was their love for each other dulling it down. Or maybe it was the lack of desire from him.

In either case, she always found herself craving something different after being intimate with him. That was why she sought it elsewhere. In strangers.

That was also why she enjoyed having sex with guests who frequented the hotel. Whenever someone checked in, she made sure to seduce him during housekeeping, hoping to get an opportunity to satisfy her needs.

Not only did these encounters quench her thirst, but they also helped relieve her stress. It allowed her to live a free life where there was no emotional baggage weighing her down.

But every time she did it, she ended up feeling a little dirty. Not only because she was cheating on her husband, but also because she was doing it with men whose faces she probably won't see again. And yet, she couldn't stop.

And among the plethora of one-night stands she had, the latest, with Oliver, had to be the best. Just thinking about him aroused her.

'Why does it feel so different when I'm with him? It's like my body is being lit on fire by his touch...' Sheila thought to herself as she caressed her skin. She recalled his muscular chest pressing down against hers, the feeling of his lips touching her own, and how he tasted when they kissed. 'Every inch of my skin burns wherever he touches. And the things he does to me... Oh god. How can an 18-year-old be so amazing? It's too much!!'

Sheila closed her eyes and bit her lower lip as she replayed everything that happened last night. The memory of them kissing besides the pool and fucking each other's brains out soon after left her feeling hot and bothered. Just thinking about it was making her wetter than ever before.

She got up and walked into her bedroom before opening her cabinet drawers to retrieve a dildo. It was one of the many she bought over the years to satisfy herself while thinking about some stranger.

After staring at it for a minute, she stripped naked and lay down on top of her bed, spreading her legs wide apart. Then slowly, she began pushing the sex toy into herself.

Even though it was larger than average, it wasn't nearly enough to satisfy her. If only Oliver was here now...

With this thought in mind, she pumped it back and forth inside of her pussy, imagining him filling both her holes with his thick, long, and throbbing shaft. Her other hand reached over to her breasts and groped her nipples. She began moaning louder and louder as her body shivered in ecstasy.

"Mmmmmmmm!!! Yes!!!!" Sheila moaned as she pumped faster and harder. She thrust the toy as deep as possible, feeling the fake balls slap against her mound with each stroke.

She thrust as far as she could go, feeling the tip rubbing against her clitoris as she went. This stimulation sent shivers through her entire being.

Suddenly, there came a clicking sound as the door of the room opened, snapping Sheila out of her imagination.

"Mom?"

She quickly removed the object from her snatch and tried covering her exposed parts, but it was futile as her son had already entered the room. Now, he was standing in the doorway with an awkward expression plastered across his face.

He was a little taller than her. His body had some masculine features like muscular arms and big hands, which she found attractive. Even though he was her son, seeing him made her think of fucking a well-endowed man. After all, she had seen his body develop since childhood.

And looking at him now, standing there, staring back at her with his mouth hanging half-open in surprise... Well... That was to be expected considering the scene before his very eyes. She was wearing nothing, and her nether region was drenched with her juices.

"Shawn? Why are you..." She could sense embarrassment and shame creeping into her voice. "I thought you went out."

"I did." He replied matter-of-factly, staring at his mother's naked form with wide-eyed astonishment. "I forgot something... I didn't think you were home already, so I just walked in without knocking."

Sheila's face flushed a crimson color as she covered herself more. "Go get out, please... How many times do I have to tell you to knock on doors before entering?"

He ignored her request and continued standing still, gawking at her.

A mix of emotions swirled within her. Sheila didn't know what to feel at that moment. Embarrassed? Angry? Pleased? Frustrated? And the most bizarre of all: Aroused? The wetness between her thighs increased further, soaking her bedsheets.

Sheila stared at Shawn as she took a deep breath to calm down, but she only managed to inhale the musky aroma from her sweat and her previous playtime with the toy, and it turned her on even more.

Clearing her throat, Sheila put up a stern expression and asked her son, "Why are you still standing there? Didn't I tell you to leave?"

Seeing that his mother wasn't screaming or hitting him, Shawn gained some courage and stepped forward instead of going backward. His eyes drank every inch of her nudity with ravenous desire. Sheila recognized the desire. She had seen many men give her the same look. Men, whom she seduced for her pleasure. But her son?

'It can't be...' Sheila thought as she nervously opened her mouth, but only a strangled groan came out instead of words. 'My son can't want that from me...? Can he...?'

Now he was standing over her, gazing down at her bare curves with admiration, his dark eyes fixated on her beautiful face. An overwhelming desire swelled inside his chest, pushing him closer and closer.

And when she remembered how Oliver and his mother enjoyed themselves, Sheila gasped.

'Wait a minute... Maybe... Just maybe... I can give it a try,' Sheila thought to herself, picturing what would happen if she took action now. How she could fulfill her lust with someone close to her and let herself bask in forbidden ecstasy. And that too with a muscular son.
