'Don't know what she's doin', brother! We gotta put a fuckin' stop to it, though!' Doug replied, stepping into his swim trunks.
'If she don't turn it off real quick, I'm gonna have to find me a nice quiet corner somewhere and jack off. My own sister raisin' a hard-on on me! Fuck it! It's too much, man!' Mick said, throwing a towel over his shoulder and patting his still-swollen crotch for emphasis.
'I know what you mean! It's bad all right! I'm gonna have a talk with her. We communicate pretty good most of the time,' Doug said thoughtfully.
Doug was having a hard time pulling his tight trunks up over his dick, which stuck out like a derrick.
'Good thing I'm headin' for L.A. next week, man! Can't stand much more teasin' from sister. I'm gonna get me some of them hippie chicks, man! I'm gonna leave you to take care of Chastity. Maybe you can cool her down some,' Mick said, scratching his crotch and grinning from ear to ear.
'L.A. sounds good, Mick. Wish I could go with you,' Doug said.
'You can! Just say the word and we both head out hitchin'!' Mick replied.
'Nah. I… I guess I'd better stay around here for a while,' Doug said, thinking about Chastity and the mysterious effect she was having on him.
'Up to you, Doug,' Mick said, slapping his brother on the back. 'Say, man, did you notice how Dad was tryin' so hard to look cool this mornin'?'
'Sure did… Guess Chastity's gettin' to him, too. Kinda ward…' Doug mused.
'Well, bell, better go down there and take that swim. Maybe that'll cool off this whacks family of ours,' Mick said, shaking his bead and closing the bedroom door behind him.
Doug stayed in his room for a while, looking down at his too-obvious hard-on. He couldn't bide a rod like that and he knew it. He would have to make the best of a difficult situation and hope that his parents and Dawn didn't notice the huge cock bulge between his legs. When he finally got up enough courage to leave the room, he did so quickly, striding into the living room to meet the rest of the family, throwing caution to the winds.
He found that the rest of the family had already left for the beach, all except Chastity, that is. She appeared at the top of the stairs again. She wasn't wearing much more than she had been wearing earlier that morning. In fact, she looked more naked in her skimpy yellow bikini than she had in her negligee. If she wore the bikini to hide her tits, ass and cunt, she had chosen the wrong garment. The top amounted to little more than a wide strip of thin yellow ribbon stretched over her tits. The ribbon, which was stretched almost to the breaking point, was just wide enough at the sides to hold her beautiful set of jugs in place. It narrowed considerably in front where it was supposed to cover her nipples, allowing the edges of her light-brown areolas to show. The bottom of her bikini was not much more substantial. It looked to Doug as if it would dissolve in the water as soon as it got wet.
Chastity raised her arms over her head and pirouetted a few times, modeling the flimsy garment for her horny brother. He couldn't help admiring her for her courage, as well as desiring her for her crotch-grabbing sexiness. As she turned on her toes, the firm flesh of her partly exposed butt quivered temptingly. Doug couldn't help wanting to run to her and reach out to cup her wantonly exposed boobs in his strong hands. He couldn't help wanting to hug her in a tight love-grip and slip his hand into her bikini bottom to feel her soft warm silken ass.
As he watched her, he felt his resistance melting away. Obviously pleased by his rapt attention, she stopped turning on her toes and raised one leg, crooking it playfully in the manner of an old-fashioned pin-up model. Doug's eyes fell between her legs, riveted to the slight swelling of her barely covered cunt mound. His eyes tore the cloth away and feasted on the imagined snatch beneath.
'Like my new bikini, Dougie?' she breathed seductively.
Doug couldn't say a word in reply. He became painfully conscious of the hard swelling of his excited prick. He realized now that she had to have caught an eyeful of his cock. He suddenly decided to shuck the whole thing and let his hot-used sister have her fun. She was too much for him.
'Okay, you win,' Doug sighed, putting his hands on his hips and standing before her with his cock bulging in his trunks.
'I win? Is that the prize, big brother?' she giggled, pointing to his jerking cock.
'You wouldn't know what to do with it ill gave it to you,' Doug teased, knowing better.
'Don't be so sure Dougie,' she retorted. 'I've won contests like this before.'
With that she ran the rest of the way down the stairs and breezed by her horny brother, kissing him lightly on the cheek as she passed through the door.
Doug stood by himself for a minute or two, thinking the situation over, or attempting to think it over. He realized soon enough that there was nothing to think about at all, at least nothing that he was capable of thinking about now. He was beyond thinking.
Standing in the doorway, Doug saw Chastity off at some distance, half-running down the winding path to the beach. Even at that distance her ass looked beautiful in the morning light.
Doug took a deep breath, stretching his muscles as he drank in the perfumed morning air. He felt strong, virile, and very much alive. There was something strangely invigorating about the air on that particular morning. It seemed that something was stirring inside him, struggling to be released. The natural elements seemed to be working together to arouse feelings for his sister that were new to him, new and strange. He started walking after her but soon broke into a run.
Chastity either sensed that he was running after her or heard his footfalls in the grass. She suddenly increased her pace. When she reached the foot of the high bill overlooking the lake, she broke from the path and headed toward a grove of trees. Doug half expected her to head for that grove since she had told him that it was a favorite retreat of hers.
A gentle breeze canted the sound of her intoxicating laughter to Doug's ears as she disappeared into the heavy grove of poplars. Following her into the grove, it occurred to him that he had never been there with her before. He was struck, even in his excited state, by the sense of peace that pervaded the grove. He was struck even harder when he caught sight of Chastity again.
There she stood in all her wildly exciting sexiness, leaning against a young poplar tree, breathing heavily after her long run. Her boobs were heaving with each breath. Her golden hair was wind-blown and her gentle, lightly tanned cheeks were barely glistening with the hint of perspiration. She appeared to him as the perfect vision of a sex-crazed sex-goddess.
The boy could control himself no longer. He stood feasting his eyes on her. His throbbing rod and lust-drunk brain controlled his every action from that moment. He forgot his relationship with his sister in the eyes of society and abandoned himself to the urgency of his passion. He sensed that Chastity was ready for anything that might happen between them.
He walked toward her with a mad grin on his handsome face and a hot hard-on jerking between his legs. She advanced to meet him, her breathing slower now, her mysterious green eyes lighting up with a strange inner glow, as if they reflected the fires of the lust burning deep within her. They both stopped a foot or so apart and looked deep into each other's eyes.
Doug reached out and touched Chastity's soft, smooth, unblemished cheek, his fingers trembling slightly. Then his hand moved slowly downward, down her neck to rest on her delicate shoulder. He looked deep into her eyes while he felt the satin smoothness of her skin. Nowhere in her eyes was there a warning to stop his explorations.
Doug thought his heart might stop when he finally brought himself to move his eager yet nervous hand from his sister's shoulder to her tit.
He had felt the offered tits of more girls than most young men and was known around town as an experienced fucker. Yet this first exploration of his daughter's body seemed more exciting than the first time he had held a boob in his hand.
The unavoidable sense of taboo in what he was doing seemed only to increase his horniness and excitement. He knew tat Chastity felt the same. He reached out with his other hand and cradled her other warm jug. Kneading the tit flesh in his hands, he managed ever so slowly to slip his fingers under the ribbon-like bikini top that covered her knockers. With little difficulty he slipped the ribbon over her hardening nipples, exposing them completely to his gaze. Her big boobs suddenly exploded out of her garment, more than filling Doug's large hands with tingling feminine flesh. Chastity trembled from head to toe, more in excitement than in fear. Doug heard the sharp intake of her breath when she felt his hands on her risked tits.
