The feeling of Sophia's soft lips suckling on his big hairy balls and her tongue lashing all over his sweaty scrotum was to Jim as always exquisite - a clear testament to the absolute depravity he had so successfully fostered in her trough the years. More than that feeling, however, it was the expression on her face that fueled his already raging lust - the expression of being oblivious to anything else around her but the means to her own sexual pleasure and the almost delirious state of mind she entered when depraved sex acts were about to be performed on or by her. He had first seen this expression on her face when she was barely a teenager, and had since found countless ways of drawing it out.<br/><br/>He fully understood the state of mind she was in, because it was so very similar to his own when he debased her in the most perverse sexual ways. At such moments the world around him seemed to consist of nothing but the two of them - everything becoming about satisfying their need for sexual highs. However, today he was certain that it would be especially enjoyable as he could watch his beautiful teenaged grandson do much the same with her - treat her like the filthy little slut she was.<br/><br/>It would not be the first time Jim had seen another male do that. Indeed, he had many times coached his sons in the fine art of sexually domineering her when they were teenagers, and had been both proud and excited to see them enthusiastically utilizing his teachings on her - both then and later as grown men. On occasion he had even shared her with trusted friends, most of whom likewise had a passion for sexually domineering women and young girls. She was unquestinably always happy to please, and indeed seemed to derive a great deal of her own pleasure from that alone.<br/><br/>Jim knew where her tongue was going the moment it departed his balls. She had literally been a sucker for men's assholes since the first time she tasted his while she was still a flat-chested child. Jim immediately spread his muscular, hairy legs even wider for her and slid his ass forward on the chair to giver her unhindered access to his asshole. God, her tongue was so wet and tickled him so wonderfully there. She had long ago learned how to loosen his asshole with just the tip of her tongue, and whenever she tasted his musky anus he would hear her primal moans of delight which made his own cock throb even harder. Already his precum was dribbling down the underside of his large dick now that her mouth was no-longer there to dispose of it.<br/><br/>At first Jim thought he heard Sophia wrong when she asked for a drink. In the years immediately preceding her meeting Ashton she had often made that request during their sexcapades, and Jim had been only too happy to oblige - a drink of course meaning a mouthful of his fresh warm piss. However, for reasons Jim never quite uncovered she stopped making that request when Ashton came into her life, and even though Jim continued to sometimes on his own initiative piss on her during sex-play - which she obviously still enjoyed tremendously - he had long ago ceased to expect her asking for it. Now, however, something seemed to have changed in her in that respect.<br/><br/>Jim smiled and his cock throbbed with excitement. Fortunately he was very familiar with the urination-enducing effects of alcohol, so even though he did not yet need to piss he knew how to quickly be able to satisfy her plea. He smirked at her, saying: "In a moment, cunt! Daddy's gotta work up a good piss first. Now do as you're commanded." The latter was a reference to Jake's words to her, wonderfully demanding words by a young boy to his slutty aunt/foster-mother. Jim then rose from the arm chair and - after stepping out of his shoes and pants - walked to the liqour-cabinet where he poured himself a big drink of scotch. Having also shed his shirt and socks he then returned completely nude to the arm-chair where he sat and enjoyed his drink while watching his daughter and grandson perform in front of him.
