George had been quite overcome by the adventure he and his sister had had with their Aunt Melanie, when they were visiting Rotterdam to do some shopping. He had fucked his sister and other relatives before, but that particular occasion, also with the other man, Joss, present, had been very special for him.
He had discussed it afterwards with his sister and the whole memory of the event had aroused them both so much, that they had ended up sixty-nineing each other until they had both been calmed down by their orgasms. Betty had compared his penis with that of Joss and found, that she had enjoyed giving head to the older man, but also, that nothing felt as good as her brother's dick in her snatch.
At dinner they had told their parents about Aunt Melanie.
'Did you fuck her?,' asked his father, when George had told how much he admired his aunt's muscular body and her pert tits.
'No, she sucked me off and then proceeded to have sex with her boyfriend,' answered his son.
'Same for me,' said Betty. 'The guy did me orally, then I fucked George, who was great, as usual.'
Their mother Meryl nodded her head and thought out loud: 'Saturday we have a get-together at Uncle Jeffrey's and I know everybody will be horny as hell, since the last time was more than a month ago. Perhaps it would be a good idea, if I asked Jeffrey to invite Melanie as well.'
'Let's invite Joss also then,' suggested Betty.
'No!,' snapped her mother. 'No strangers. I wouldn't feel comfortable. And I must say I am happy that you did not let this Joss character penetrate you. It is bad enough already that he satisfied you orally. Stick to the family, is my motto.'
Betty looked at her father who nodded his approval with what his wife had just stated.
'I think you're absolutely right there, Meryl,' he said. 'And besides, what do we need an extra man for? In our family there is already a shortage of good pussy and I have never heard any of the ladies complain of a lack of satisfaction at our family parties. But the idea of inviting Melanie appeals to me, too. I can't understand why we never thought of that before. I mean she has a firm body and a tight ass and her tits seem to bounce nicely.' 'Gary, why don't you call my brother Jeffrey and tell him to include our sister in the invitation for Saturday,' asked his wife, now with a discernible lilt of excitement in her voice.
'Great!,' was Gary's reply and he did as he was told.
Betty went up to her room to do some homework and George joined his mother in the washing-up after dinner. While he was drying one of the dishes, his mother looked at him from aside and observed: 'It is some time since the two of us had a good fuck, isn't it? If I remember correctly, since you have shot your load in my sister Melanie's mouth, I haven't felt your young cock in my twat any more. Do I see a relation there?'
George looked at her in astonishment and hastened to reassure her.
'No, Mom, that has nothing to do with it. It's just that I have been banging Betty quite a lot lately and Dad and you are at it every night, so I figured that you could do without me for a while.'
'Okay, son,' said his mother. 'Then it's fine. But perhaps it would still be a good idea if I slept in your bed tonight and let Dad and Betty make up their own minds. They too haven't had a decent fuck together since weeks. Perhaps you're right and I have been a little over-possessive towards your father lately. You know, he has the gift to fuck me in such a heavenly way. Well, I'm sure you know, because you have witnessed it often enough. And I must admit you are nearly as good in the sack as my old man, but I feel helpless every time he so much as looks at me with those hungry eyes of him and that tremendous bulge in his pants. That is another thing you inherited from him and I am glad that you did. I don't know if I could fuck you if you had just a tiny willy.'
George was proud when his mother complimented him on the size of his penis. She had said more than once, that his member was already impressive in a flaccid state, dangling between his legs and that his erection only made it downright awesome. But she had also emphasised, that she found his cock at its best when it was invisible, which meant deeply hidden in the folds of her maternal cunt or in the young and muscular snatch of his sister. His mother had been watching her two children at many occasions, when they made love. Sometimes she would just sit and watch, but she was also known to guide and advise them on techniques and positions. And very seldom she had actually joined them in their love-making, usually by straddling her daughters lovely face and asking her to orally satisfy her while her brother was pounding away in her. Her motherly feelings often drove her over the threshold of orgasm when she saw her son dropping his semen in her daughter's hot body and at the same time saw Betty's spasms as she also reached the peaks of sexual pleasure.
After the washing-up was finished, Betty returned from her study and they all had a quiet cup of coffee.
'George and I are going to hit the sack,' Meryl declared and she stood up. George followed her.
Betty smiled at her brother and joked: 'Watch out, she is after your sack.'
'Only after the contents,' was her mother's quick reply. They all laughed.
After they left Gary said to his daughter: 'I don't feel like going to bed. Shall we disrobe and view a video? I have a recent movie with a mother-and-son theme in it, that will give us an idea of what is going on upstairs, while we amuse ourselves with each other.'
They shed their clothes, all the while looking intently at each other. Every time she watched her father get naked, Betty was impressed by the shape of his taut body and aroused by the sight of his dangling penis, that usually rose to half-mast as she showed her perfect curves to him. Gary could not cease to admire hi daughter's lithe body with the perfect breasts and her neatly trimmed bush.
They sat naked on the couch and watched the movie together. After viewing it for some ten minutes, Betty got bored and a little restless. As she looked around she realised that her father was far from uninterested by the story and the images on the screen. His pole was extremely swollen and lay on his belly, the tip easily reaching his belly button.
Betty let herself glide from the couch and nestled between her father's legs. She took his member in her hand and brought the tip to her lips. She brushed the foreskin lightly with pouted lips and then proceeded to lick it very carefully with her pointed little tongue. Gary continued to watch the movie, that really turned him on, but the feelings in his groin distracted him more than a bit, especially when his daughter cupped his ball-sack in her soft hands and took the entire head of his cock in her hot mouth. He alternated the images on the screen with tender looks upon Betty's now bobbing head and considered himself extremely lucky to have in the house two horny women that he could enjoy without the risk of them getting jealous. Betty was an excellent cocksucker, even a little better than her mother, he had to admit, and she always brought him to a quick first ejaculation. Tonight was no exception to the rule and after about a quarter of an hour Betty's expert fellatio paid off: at the same moment that the son in the movie filled his mother's cunt with his potent sperm, Gary groaned and gave Betty three bursts of his own semen, filling her mouth completely. Betty swallowed her father's cum and held his penis in her mouth as it got back to its normal size.
'Hey!,' she thought. 'The guy is fifty years old. He cannot stay hard after coming, like my little brother can.' But she knew that it would take no longer than ten minutes for him to rise again, this time to the task of fucking her dripping twat, that started to demand satisfaction.
