"Errr, Hi son. Sorry I can't stop I need to dash to the office, there's a bit of an incident taking place" Jim's father announced as the two bumped into each other by the front door. His father seemed very distracted as he absentmindedly added "Err, don't go in the bedroom please. I'm hoping I won't be long."
It wasn't an uncommon occurrence. To Jim it seemed his father thought the business would fall down if he wasn't there at the helm all the while -- 'Whatever' the tall eighteen year old shrugged and made his way back to his own room. As he passed the bedroom of his father and stepmother he paused, 'I wonder what Dad meant about not going in their room. It's not as though I go in there very often.' Jim paused at the door but couldn't hear anything, 'Roz's car is outside but then she often got picked up by one of her friends to go shopping or such.' He was about to move towards his own room but he couldn't stop think about what his father had said. He reached for the door handle and turned it slowly; silently. The catch disengaged and so Jim gently pushed the door open slightly -- still nothing to answer why his dad had said not to go in. He pushed the door open further and that's when his breath caught in his throat.
Lying in the centre of the bed was his stepmother with her wrists and ankles bound to the four corners of the bed. He had always secretly admired her lithe shape but she looked amazing now dressed in burgundy lingerie which showed off her flat stomach and large breasts off to perfection. She lay still as if asleep although he doubted it could be a comfortable position with her arms and legs spread out. Thankfully she was wearing a blindfold and so couldn't see him but she must have heard something as she turned to look towards the door.
A warm welcoming smile spread across her face as she mumbled "Mmmm, I knew you couldn't stay away for long." A shock of panic ran down Jim's spine; he had been discovered but then he processed her words further and realised Roz thought he was his father. This was amplified when she added "Why don't you come over here and put me out of my misery by coming to play with me." Jim's natural reaction was still to turn and shut the door again but then she would tell his father that someone - Jim obviously -- had entered the room when his father had specifically asked him not to. Roz sealed his fate when she begged "Come on baby, I'm completely helpless now. You can do whatever you want with me; I'll be your personal slut anytime."
'Oh god' he mused to himself 'She looks amazingly sensual as she is.' Jim took a faltering step inside the room and as if being drawn by some invisible force stepped up to the bed.
The smile on her face broadened when she sensed him step up to the bed. "Mmmmm, I knew you couldn't resist me" she purred as she wriggled around as best, she could in the restraints. "You can do what you want while I'm like this."
It was obvious that she still thought Jim was his father but that didn't stop the lad reached a hand down and running it gently across her side; the touch was enough to make her shiver with a trail of goosebumps popping up in the wake of his hand. "Baby, don't tease me. You know I like it tender sometimes but this is not that time; take me" she complained. As Jim continued his hand came across the elastic of her bra, this was Roz's opportunity and she twisted away from his side of the bed so that her right breast was squarely in the grasp of his palm. What else was he to do other than start to cup her warm flesh as he flexed his fingers, glorying in how her flesh undulated in time with his finger flexing. "Yesss, that's more like it" Roz hissed at him.
The contact was through the lace cup of her bra but the warmth of the flesh beneath could not be ignored and the tent in the front of his trousers expanded. He had felt up girls his own age but they had always paled compared to the lush woman arranged before him now but now he had his hands on her his instincts kicked in. With her free hand he unfastened his trousers and allowed them to slip down effortless until they pooled around his ankles. He then reached down to turn her head to face him; his next actioned seemed to take place in slow motion as he leant his hips slightly forward until the head of his dick lay against her lips.
"Mmmmmm" came the contented moan from her lips as she curled her tongue around the head and craning her neck forward allowed her to take the head entirely in her moist warm mouth. Her husband's dick felt different in her mouth 'it must be being bound and blindfold' she considered. Roz was gently dipping her head back and forth to progressively take more and more in her mouth.
It felt heavenly to Jim, he had received head before but his prior experiences weren't as profound as he was now. He tilted his head back and groaned but suddenly thought it would give himself away and so muffled his groan while his other hand continued to determinedly grope at her breast. His stepmother was very pretty, especially when she smiled, but seeing her with her lips wrapped around his dick meant she took on a new degree of beauty. She herself let out a contented moan when she tasted his precum on her tongue at the same time as his thumb and forefinger came to rest on her large rubbery nipple and tweaked at it mercilessly. This kind of treatment was making her squirm even more although to her credit she never disengaged her mouth even when the teasing tipped her over the edge and she rested his dick on her lips as she gasped and groaned her way through her obviously needed climax.
Jim didn't want her getting a respite and wriggled the fingers of his left hand inside the waist of her lace panties. By now Roz had taken his dick inside her mouth and was still wriggling around only this time she added humping her hips up and down in response to the lad slipping two fingers inside her to the second knuckle. "Oh god" she mumbled around his dick as she started headlong to her next climax just a few minutes after her last. "Yes, yes" she continued to mumble continuously until finally she lunged her hips one final time as her muscles clamped down on the invading fingers.
Jim stepped back to take in the sight before her. Roz's legs and arms were still held wide, her chest rose and fell in gasped breaths while her forehead was beaded with sweat. While taking in the sight before him Jim brought his two fingers up to his mouth so that he could slip them inside and he could suck on them so he could savour the sweet tangy juice on them. Roz's breath was returning to normal as she mewled "Untie me and take me. I want you to fuck my brains out like you never have before."
Jim chuckled inwardly suspecting she'd be shocked when the penny dropped it was him and not his father. He kicked off his trousers and lifted his t-shirt clear before shushing her, "Shh."
Roz's senses next picked up the bed dipping on one edge and felt him climb between her outstretched legs. She would have preferred her legs free so that she could wrap her legs around her husband's hips but had to content herself with feeling him pull the leg of her panties aside. This could only mean one thing, the much needed fuck was imminent and sure enough she felt the spongy head of dick engage her out labia before a single thrust sent him deep inside her flesh.
The warm copious juices bathed Jim's cock as he sank into her; her muscles tightened around his dick the deeper he sank inside her until he was inserted to the hilt. "Oh god yes" was Roz's reply to feeling his balls graze against her, prompting her to raise her hips as he slowly pulled back -- she didn't want to be losing him anytime soon but he soon reversed course and sank deeply inside her again. More "Oh god" incantations followed as she felt his lovely thick dick penetrate deep inside her folds.
Roz was so into the treatment she was receiving that she was twisting her head from side to side. Jim was too focused on thrusting his way inside to notice but when she gasped "Oh my god Jim what are you doing" his head shot up in shock to see that the blindfold had slipped down and she was looking at him with one exposed eye. The shock made him hold still until his stepmother begged "Please don't stop I'm nearly there" as she thrust her hips back at him to encourage him to continue. Roz wriggled her head more so that the blindfold slipped down to her nose, the two lovers could then stare deeply into each other soul while the handsome eighteen year old ploughed inside his stepmother. His rhythm was still a little off from the discovering and so Roz decided to encourage him further "Oh yes, you're amazing. I can't believe how big you feel inside me."
This seemed to do the trick as Jim resumed his former rhythm eventually tipping her over the edge for the third time in such a short span of time. As she calmed down Roz resumed thrusting herself against her stepsons dick asking him "Please don't stop, I want to feel you coming inside me." Now this was something very new to Jim, his limited experience to date had meant he used a condom letting fly inside her was a whole new dimension and he felt the come travelling inside him as he thrust one last time; it felt amazing.
The euphoria of his climax quickly dissipated for Jim as he gazed down at his stepmother's concerned expression. He sheepishly pulled back until his cock was clear of her pussy. Roz immediately felt his come start to trickle out of her well fucked pussy. "I think you'd better untie me. We need to talk young man" she said sternly, what she couldn't voice was how amazing her pussy felt right then; 'well fucked' was something of an understatement. Jim immediately scrambled to untie her wrists and had started to undo her ankles when she added "that's enough for now" as she patted the bed beside her.
He was dreading what her next words would be but resolved to address them head on. He started the conversation with "I'm sorry about that, you just looked so amazing stretched out like that. Please don't be mad at me, I just couldn't help myself. Dad had to rush out, but he expressly told me not to come nosing in here but after saying that I felt compelled to look."
