Steve woke up to a bright new morning, the sun shining in through his curtains. Beside him in his bed was Isabella, his beautiful girlfriend. She often stayed over at his place. Steve still lived with his parents while he and Isabella saved up for a place of their own. They were engaged to be married, Steve 20 and Isabella 19, and Steve's parents were always very welcoming and happy to have Isabella under their roof.
Isabella was a shy girl who perhaps didn't realise just how gorgeous she was. She often had men looking at her and her perfect slim body but she was reserved and Steve was her first proper boyfriend. They had been together for three years - almost childhood sweethearts - and Steve was the first guy she'd had sex with.
Steve had really managed to open her up sexually. They had a great sex life. It was regular, erotic and fulfilling but sensuous more than filthy. They were not yet ready for any major experimentation. She woke to see Steve looking at her and put her arm around him across his chest. Being naked together that warm morning, Steve soon got an erection. They grinned at each other. Looking at the clock, they saw there was 20 minutes before Steve needed to get up and go out to his job. He often woke up earlier than he needed to, especially on a morning when his dad John had got back from the night shift he did in alternate weeks. His mom, Pam, was already up and out of the house for her job, starting early. And shortly after she had left, his dad would come him, closing the door, dropping his keys on the table, and going into his bedroom to catch up on sleep. He would usually stir Steve and Isabella at some point no matter how quiet he tried to be.
But as young lovers they always wanted to make the most of the quiet time they had in bed together before Steve had to leave. As she was studying, Isabella had less of a rush in the morning. They knew when each other was ready for sex and were soon kissing and playing with each other. Isabella started rubbing Steve's cock up and down while he played with her pussy, rubbing her clit and then fingering the wet opening to her vagina.
When they were both wet, Steve climbed on top of her in a 69. They loved each other's morning tastes and Isabella would often come from oral. With his skilful tongue flicking across her clit, she soon did. They hoped John was asleep by now, in the next room, because when she came Isabella wasn't very good at keeping quiet. After she had come, she liked a fuck, so Steve climbed off, moved around and then entered his big hard cock into her welcoming pussy. With time running out, there was no chance of a long slow fuck of the kind they both loved. Rather, Steve quickly built a rhythm, faster and faster, and before long unleashed his hot cum deep inside Isabella's pussy. He gave out a stifled groan as he came. The fuck was mainly for him. Isabella would have liked at least one more orgasm. But as Steve was soon to be out, he had to think of himself. He was a big comer and left her with a huge creampie. The hot, thick spunk slowly ran from her unshaven pussy and down between her ass cheeks as he withdrew his still hard and slimy cock. He squeezed out a last few drops from the end of his cock on to her dark hairy bush.
After catching his breath, Steve jumped up, in the shower and out as soon as his could. Isabella snuggled down, trying to get a little more sleep, freshly fucked. Steve looked in the bedroom to say goodbye but could see she was already snoozing so drove off to his day at work.
In the next room, John had been listening carefully to what was going on. When he came home from night shift, with Pam already gone, he would enjoy having his bed to himself. He would usually strip off and play with his cock. He had come to realise that his son and his girlfriend would often fuck in the morning. Some days they didn't wake up in time so he had started clattering around a bit to make sure he disturbed them. His regular morning wank was now usually aided by hearing Isabella getting fucked. Sometimes, John would stand naked next to the wall, listening to as much of the fuck as he could hear. When he heard Isabella come, it would often make him come too.
John was a filthy old pervert. He had many times stolen a pair of Isabella's dirty panties and sniffed them while wanking. This morning, he was wanking but had not managed to jerk himself off. He was left feeling very horny and unfulfilled. When Steve was showering, John continued playing with himself but without coming. As Steve left the house, John's wank was ongoing.
Feeling horny, and having perved over beautiful, young and vulnerable Isabella for so long, John was suddenly overcome with uncontrollable ideas of filth. Naked, he crept out of his room and walked the few steps to his son's, in whose bed the just-fucked Isabella was snoozing.
In his walked, still rubbing his big hard cock. Almost at the side of the bed, Isabella opened her eyes in alarm.
"John! What on Earth are you doing?" she cried out.
"I can't bear hearing you two fucking any longer," he replied. "I need some of this action for myself."
With that, he pulled back the sheet and put his face between her legs.
"No!", cried Isabella. "Don't."
John started licking her soiled pussy. It smelt of the sperm his son had shot into her pussy. He saw the white cream dribbling out and started licking it up. He swallowed the cum and then turned his attention to her clit.
"No, please don't," she protested again.
But as the old pervert licked more and more, her clit stood out from her hairy pussy. He could tell her filthy cunt was responding. Her whole body tensed up. She tried to get off the bed but he held her down.
"Please stop it. I'm coming" said Isabella.
She had seen John look at her for some time. Steve was the only man she had experienced sexually. John was mature and at times masterful. But she also got the impression he was like more of an animal than his son. He seemed filthy in what he said and did. He had a raw sexual energy that intrigued her. And yet she could never dream of experiencing her boyfriend's dad sexually for real.
But now, he had taken control. Held down, there was nothing she could do. And his expert tongue seemed so much more skilled than Steve's. What's more, she saw he had a big hard cock when he entered the room: so much longer and fatter than Steve's. The sexual energy she had sensed was now fully manifest to her physically. Despite saying no, she felt herself losing control and starting to orgasm.
Waves of pleasure swept through her dripping wet cunt as John licked it and then through her whole body. In her young, inexperienced life, as such a shy and reserved girl having been touched only by one man before, she had never known an orgasm as all-consuming as this. And with the tongue of John, the sperm of Steve and her own pussy juices, she felt the wettest she had ever been.
When she had come, John picked her little ass up from the bed and turned her round. He stood her on all fours and got behind her.
"What are you doing? Please, no!" Isabella pleaded.
"You're a filthy slut!", responded John. "I hear you every morning getting fucked like a slut. And now I've seen how easily you come. You really want it. Admit it to yourself!"
With that, he entered his huge cock into her tight little teen pussy. Without it being quite this wet, it's unlikely he would have succeeded. But he managed to squeeze it in and it felt magnificent to him after years of fucking Pam. He slid in slowly at first, savouring the gliding sensation. And Isabella gasped as she came to terms with having such a gigantic cock inside her.
"No, no," she said under her breath, but this time with less conviction.
He started picking up pace, then fucking her harder and harder. Her head was swimming. She knew it was wrong. She thought of Steve. What would he say? But her cunt was responding to this cock in a new and unexpected way. She felt herself starting to come again. She'd never orgasmed through penetration before. But it built and built, out of control. She shuddered as her orgasm was even more intense than the first John had given her. Her pussy gripped tight around his cock and milked it as she contracted. He felt himself coming. The sperm came up from his balls and through his cock and he let out a scream as he emptied inside her a huge load of his daddy cum.
