Jim thought back to the Fourth of July that Summer, just weeks after his sister had turned eighteen. Jim had been standing with his friends at the parade on Main Street, when Betsy and a group of her friends had walked by. Jim had looked over at the group of girls in their summer dresses, white, pink, blue and yellow, bright against the creamy texture of their bare tanned legs and arms in the bright morning sunshine. As they passed, waving and smiling, Jim had locked eyes at the very last moment with his sister Betsy. He had been suffused with trembling heat when he saw the look of embarrassed intimacy that they’d shared, in the brief instant before her eyes dropped down, and she walked away with her friends. He knew that she was thinking about the treehouse in that moment, just as he was. “I wish we could do it again,” he said softly. “I’ve wanted to for a long time,” he admitted. “I just didn’t think that you did…too.”
“No,” Betsy whispered. “I knew it was wrong, but…I couldn’t stop thinking about it.” Betsy sighed. “How much I wanted to do that for you again.” She slumped back into the chair, turning back toward the window and looking over the back lawn, relieved and ashamed to have finally admitted that she still fantasized about sucking her brother’s dick.
“We have Susan’s family coming in for Christmas,” Jim reminded her. “But maybe we could make it out there for New Year?” He sounded hopeful. It was one thing to admit that they still fantasized about having done those things, but quite another to actually go through with reliving the experience. Jim’s heart was pounding in his chest and his cock was throbbing with the possibility that his sister would agree to something like that. The silence over the phone seemed to stretch out forever, even if it was only for a few moments.
“I’d love that,” Betsy’s voice trembled as she said it. Her heart fluttered in her chest and she could feel her pussy had become slick with anticipation. “It would be wonderful if you could come…I mean if you can make it.” She felt flustered and embarrassed, tripping over the words.
“I’ll talk to Susan tonight, Bets.” Jim felt jittery with excitement. “I’ll find a way to make it work.”
“That would be wonderful,” Betsy gushed. “I’ll be counting the days.” She sounded just like the girl who had once turned eighteen, all those years ago.
“Me too, Bets.” Jim grinned. “Love you.”
“Love you too!”
Betsy had barely made her way down the hall to their bedroom before she was pulling down her stockings and her damp panties to sit on the edge of the bed, her hand under her skirt and flickering through the wet folds of her pussy. A rotating collage of images came tumbling through her memory as she increased the speed and intensity of her fingers, twitching across her yearning clit, eager to be led to release.
As awkward as it had been, learning to take her brother into her mouth, her most vivid memory was the first time that she had made him cum. She had started on her knees as they had the few times before, but she had ended up laying on the rough boards of the floor, her head propped up against the wall of the small tree house, with Jim straddling her, as his hips drove his slender, curved dick into her mouth, and she struggled to keep up. She had backed up a little at a time as Jim had pushed more urgently, trying to find satisfaction in her warm, wet mouth.
Now pinned against the floor and the wall, Jim had increased the tempo of how much he was trying to plunge his cock into Betsy’s mouth. When she was finally able to push Jim away to catch her breath, she had barely been able to get out the words, “Ow Jim, it’s hurting the top of my mouth!” when she looked over to see a spurt of white cum jet out of the end of her brother’s cock. Jim grunted as his dick was pulled too soon from the ecstasy of his sister’s mouth, just as the first wave of cum started shooting out, over his sister’s bare arm, and shoulder, to land on the wooden boards of the treehouse wall.
Betsy had looked on in fascination, as the tip of her brother’s dick hovered, just a few inches away, and wave after wave of his cum pulsed out, finally tapering out, to drip, hot and slick, onto her bare arm. She watched Jim stagger back to rest against the far wall, his dick still twitching and a last small glob of cum oozing from the tip of his flushed pink dick, still shiny from her saliva.
Betsy swallowed, grateful to have relief from her brother’s cock thrusting repeatedly into her mouth, as she stared transfixed by the sight of the pearly white cum, finally losing its balance atop the glistening head of her brother’s pulsing dick, and sliding off the tip down the length of his still twitching dick. Betsy stared dumbly over at the drops of cum on her arm and the larger streams that were dripping down the rough boards of the treehouse wall beside her.
Jim came to his senses as he caught his breath, apologizing for getting his cum on her as he pulled off his t-shirt to wipe it from her arm. Luckily none had gotten on her sleeveless tennis top.
“I’m so sorry, Bets,” Jim looked at her sheepishly. “I guess I just got carried away.”
“It’s…it’s okay,” Betsy had replied, still half in disbelief. “I’m sorry I couldn’t keep going, but it was rubbing the top of my mouth and you were just going so fast,” she explained.
“I didn’t mean to,” He looked into her eyes to assess how badly he had hurt or scared her. “It just felt so good like that.”
“It did?” Betsy felt a strange sense of pride and accomplishment as he said it, a bit stunned that she had brought her brother all the way to the point of climax. “You really liked it?”
“Oh I loved it,” Jim gushed and bent over to pick Betsy up and kissed her without even thinking about. He pulled away from the kiss, surprised that he had done it, and wrapped her up in a hug. “It was amazing, Bets,” he spoke softly over her shoulder.
Betsy had been too surprised to react to her brother’s kiss, and felt a little awkward that he probably hadn’t remembered that she had just been sucking his dick, just before he had. But she felt a deep sigh of contentment go through her, as her body melted against the hard, lean, shirtless torso of her handsome older brother and she felt his heart thumping through his chest.
All Betsy could remember was how time had slowed, watching the first time she’d ever see a man ejaculate, her brother’s long, smooth, perfect dick pulsing with the surge of the first male orgasm she’d ever witnessed. Her fingers froze in her pussy as it began to contract in spasms of shuddering pleasure, remembering that first of many times that she would bring Jim to a climax that Summer. How she had initially been horrified by the fact that he had straddled her chest, and thrust himself recklessly into her mouth, seeking that ultimate pleasure, but how the feeling had melted into pride in the hours and days that followed. How all these years later, it now seemed innocent and delicious, to remember that sweet young man, awkwardly thrusting his cock into her mouth, until she had brought him to release.
