Luke was pleased with the way his boys were turning out. Dick was going to be the intellectual one. He knew that already. In fact, he thought it might be kind of nice to have a lawyer in the family. He had always been a little worried about Dan. Things seemed to have come too easily to his handsome first son.
Dan had grown up with the adulation of high school cheerleaders and football groupies. Though he had won a football scholar-ship to college, he had never paid much attention to books. As little as he could get away with had always been his approach as far as homework was concerned. Luke had been afraid his big son might end up blowing all the favor fate had dumped into his lap. At last, though, Luke was starting to relax about Dan. It looked like the boy was growing up. After a half-hearted stab at four or five different careers, Dan seemed to be making a success of his job as a real estate salesman. He was making money and he was talking seriously about starting his own brokerage. The most impressive thing about Dan these days, though, was the way he behaved toward his beautiful girlfriend. Luke knew his son had been through probably hundreds of women. There were times when he had felt a little jealous of the variety and quality of Dan’s ‘honeys’. But Luke basically believed in the institution of the family. He wanted to see his son with one woman, a woman who could help turn him into a better person-a woman like Lucy. Lucy might not turn him on so much any more, but Luke could not imagine anyone else for a wife. When he had said” ‘till death us do part” to Lucy, he had meant it. The way Luke saw it, Dan seemed to have those same kinds of feelings for Sue. Luke could see why. Not only was the blonde beautiful, but there was a special kind of quality about her-an energy, a determination that made a man want to tame her. It even made Luke want to tame her, and the older man regretted having those kinds of feelings about his son’s girlfriend.
He could not deny the attraction he felt for the young beauty, though. She was quite a woman. He could imagine she would be a dynamo in bed. The very thought of her voluptuous, big-titted body, naked between the sheets, made the man tingle all over. He and Lucy did not make love much any more, and Luke spent a lot of time half-conscious of being horny. He could not bring himself to being unfaithful to Lucy, but he could not get excited enough about his wife’s sexuality to want to fuck her much, either. Luke was a frustrated man, these days. Having a couple of young people around who radiated sexuality did not help him any. But he liked having his family around him. He hoped Dan would decide to marry the beautiful Sue. Maybe once she was officially Dan’s wife-when there was no doubt about the fact that they were sleeping together-then Luke would bury once and for all the forbidden cravings he felt every time he looked at her. He hoped so. Luke worked hard managing his construction business. It did not happen often, but every now and then he treated himself to an afternoon off. He thought today he might go home and drink a couple of beers with Dan, get to know his son better.
While he was at it, he could put a little pressure on the boy to make an honest woman of that bigtitted girlfriend of his. Despite himself, Luke was remembering how Sue had looked in a tight cashmere sweater, the night before, as he let himself into his house. He heard no sounds of activity in the house, and for a disappointed moment he thought he would have to spend his afternoon off alone. Lucy, he knew, was at a fundraising meeting. But where would Dan and Sue go? They had said last night they were going to hang around the house today, maybe swim in the pool, relax. That was it! Luke grinned. They must be out back by the pool! The quickest way to the pool was through the house and out the sliding-glass doors in the dining room. But Luke did not take the quickest route. Instead, he went to the garage first to put away some things he had brought home. The door at the back of his garage was closed. Luke had it open only a little way when his heart did a somersault and his eyes threatened to bug right out of his head. Dan and Sue were by the pool, all right. But what they were doing was nothing so innocent as swimming and sunning.
Sue was lying spread-eagled on her back on a towel, wearing only the top of a two-piece bathing suit. She was moaning and squirming in ecstatic delight while Dan knelt between her legs, eating the hair-fringed slit of her pussy. Luke could not believe his eyes. It was as if he had suddenly walked in on a live enactment of his most forbidden fantasy. Only, in his fantasy, it would have been him eating that wet pink pussy with such relish. “Mmmmm ... baby ... your pussy tastes great,” Dan mumbled between tongue-stabs. Talking only seemed to make him impatient, though, for more of his girl’s sweet-tasting juices. He extended his tongue and swirled it around the peak of her aroused cut. Then he slipped it down farther to attack the yielding hole of her cunt. Luke had a bird’s-eye view of everything. And what details he could not make out with his eyes were generously furnished by his imagination. For one fleeting instant, he thought he ought to be annoyed with the younger people for taking advantage of their time alone at his home to indulge in such wanton perversion. But he knew he would only be betraying his jealousy if he tried to act the irate father.
In Dan’s shoes, he knew, he would be doing the very same thing. And how he wished he were in Dan’s shoes! The blonde’s face was wreathed in sultry smiles as she swiveled her hips up to feed her cunt to her boyfriend’s face. “Mmnmm ... yess, Dan darling ... like that! Eat my pussy, lover! It’s 5000 wonderful!” Christ! What a sexpot! Luke thought as he crouched inside the garage, watching the progress of the lewd lovemaking between his son and his big-titted girlfriend. She was even better than he had expected she would be, though he had never expected to actually have a chance to see her in action. He watched her tongue dart from her mouth in passionate anguish as Dan tongue-fucked her deep. He watched her reach up and grab hold of her lush tits, fondling them and pinching them to enhance the sensual effects of her growing abandon. One ripe globe popped out of her skimpy suit-top. Luke found himself licking his lips as he contemplated the tempting picture of the blonde’s ripe sex-honed body. She looked incredibly appealing lying there, almost naked, with just that little bit of bikini to accent her obscenely exposed curves. The older man’s eyes roamed frantically from her beautiful flushed face to her big tits to her dark-blonde bush of pussy-hair. Dan’s head was in the way of her cunt-slit, but Luke could imagine how hot and wet it must be, how tangy her free flowing juices must taste. He swallowed hard. His throat was getting dry. Somewhere in the back of his head, Luke knew he was in trouble. He had been putting a lot of effort into trying to forget Sue’s well-evident female charms. He knew he could never forget them now, not with memories like he was recording right now. Knowing she was Dan’s girl friend did not help.
Luke was growing more certain in his opinions about what kind of woman Sue was-she did not need to be married to indulge in wanton sex with a man. Who knew how serious she even was about Dan? After all, they had only known each other four months. Maybe she even had other men on the side. She was nobody’s woman yet. As Luke had sensed from the beginning, Sue was definitely a woman with a mind of her own-and a body willful enough to go along with it. Much as he did not want to let it happen, Luke’s imagination was taking more and more liberties with the information he had just gained about Sue. He was letting himself go. His conscience forgot to remind him that he. should not be having fantasies about his son’s girlfriend; he was too engrossed in thinking what those full bouncy tits would feel like. What it would be like to suck on her nipples until they were hard as little bullets. How she would sound writhing and moaning under him while he fucked her to ecstasy. It took no imagination at all to summon up the vocal effects. They were right there, hovering in the afternoon air, assaulting his ears like the strains of some powerful aural aphrodisiac. “Ooohhh ... God-d-d! It’s getting soooo good! I’m getting there, Danny! You’re doing it to meee!” She pulled her knees up so her feet were resting against the man’s ears. She used the leverage from her feet to wriggle her ass off the ground and back down again.
