Kelsie runs up to the front yard of her house before slowing and doing a few laps around the driveway as a runner's cooldown. The beautiful young woman is a slim, trim Strawberry blond standing 5'9" tall with, as you may have guessed, a runner's body. Soft and curvy in all the right places while not having an ounce of extra fat anywhere. Her Hazel green eyes sparkle with intelligence and humor unless angry, then watch out. Her porcelain skin is completely unblemished except for the sprinkling of freckles across her nose, upper chest, and very lightly down her arms. Her hair is pulled back in its usual ponytail to stay out of her face while running.
She had just finished running home from the city bus stop ten blocks away as she returned home from her friends. She ended up coming home early, shortly after lunch, since her friend's mom had drafted her into service to go grocery shopping before the family's upcoming camping weekend. This was the beginning of her first summer after graduating high school that spring, a few weeks prior. When she was done cooling off, she went into the house using the key from the rubber curly bracelet on her wrist.
Meanwhile, unknown to Kelsie, her older brother Mitchell was just getting out of the shower, having also gotten home early from work as a lifeguard at a local tourist destination, a lakefront swimming area. Mitchell is a well-put-together guy like his sister at 6'1" and 170#. His activity besides swimming since childhood is basketball. He was a power forward for their high school team, The Shermer H.S. Bulldogs. His sister had been a long-distance runner. While Kelsie is very fair-skinned and haired, Mitchell is dark with deep brown hair and bright blue eyes.
Neither were short of dates during high school, Mitchell had dated one of the cheerleaders, and Kelsie was off and on with a band kid. Since neither knew the other was home, it was bound to happen, a little mishap at the bathroom door. Kelsie started stripping and heading for the shower while Mitchell was drying his hair as he stood just inside the bathroom. Kelsie ended up barreling into her naked brother topless and shucking her shorts and panties. She ended up bouncing back, tripping on her shorts around her ankles, and landing at Mitchell's feet, essentially naked. Her view was very erotic as Mitchell was standing there drying his hair, sporting an 8" erection.
She sucked in her breath at the sight. For some reason, she flashed back four years ago to the summer Mitchell had saved her life and became her Hero.
They had been playing and swimming at the same lake Mitchell now worked at. A bunch of them had been out on the floating dock about one hundred feet from shore. When Keslie couldn't get up at the side she was on from the water. She decided to take a shortcut under the dock like they all had at some point. Mitchell had seen her and grinned as she gave him a thumbs-down gesture, and he knew what she was up to.
His smile left his face when she didn't appear in a few seconds. After a few more, he shouted her name and jumped in, looking for his sister. He found her trapped beneath the dock by a wad of abandoned fishing line that had caught her foot, and she couldn't reach air either. Her face showed she was near panic. Mitchell did the only thing he could and ripped the line from around her leg by yanking it with his bare hands, getting cut in the process but freeing his little sister. He brought Kelsie up, gasping and coughing, and got her onto the dock with their friend's help. One of the guys wore a t-shirt and gave it to Mitchell to help his cut hand. But Mitchell was all about Kelsie. Once he knew she was alright, he took care of himself. Right then, Kelsie's hero worship of Mitchell began. It continued through their high school days to that moment.
Mitchell whipped the towel from his head, looking to see what had just happened. That's when he got an eyeful of his beautiful naked sister, her womanhood on display due to how she landed, not to mention her handfuls of firm perky tits with small areolas capped with bright pink nipples, ones currently hardening with excitement. As if on autopilot, Keslie moved to her knees in front of Mitchell and, while looking up into his eyes, grasped his turgid member and went down on him. Mitchell gasped in total shock, and then the wonderful feeling kicked in, and he moaned her name. "Oh, Kelsie."
He didn't move to stop her, so Kelsie just kept going, doing what she had dreamed of so many times since his saving her. She had the presence of mind to finish getting her shorts and panties off and quickly flipped off her short socks, too. Now, she was completely naked and on her knees in front of her hero, sucking his cock with all the skill of her short experience. Mitchell finally reached down and began stroking Kelsie's hair ever so gently.
"Oh, Kelsie. You look so beautiful like that. I have wondered what it might be like to be with you, but I could never do anything that might hurt you. So I just appreciated my little sister's beauty and swore to protect you." He gasped right then as she sucked a little harder right at the tip of his cock, lips locked around his glans. Her head continued to bob up and down. She wanted his seed, and she wanted him to fill her mouth with it and swallow every bit. Using every trick she learned from experience and the internet, she soon received what she had wanted for so long.
Mitchell groaned out, "I'm going to cum, Kelsie."
She picked up the pace further, then when she felt him swell, pushed him into her throat to take the first few gobs of his spew. She then pulled back and collected the rest in her mouth. She tasted his essence in delight with her own deep moan of pleasure. The added vibrations made Mitchell spew an extra gob of cum with a loud moan too.
Kelsie pulled off her brother's cock with a popping of suction. She tilted her head back, opening her mouth and showing Mitchell his load before carefully swallowing it in delighted ecstasy.
"Oh, Micthell! I've wanted to do that since shortly after you saved me. I love you, big brother. Would you take me to your bed and make love to me?" Kelsie admits, then nearly begs him.
Mitchell drops the towel then, leans down, and picks up Kelsie in his arms like a bride on her wedding night. She puts her arms around his neck and snuggles into his chest. He walks her across the hall to his bed, lays her gently down, crawls on top of her, and kisses her deeply. They make out for several minutes. Soon, Mitchell's cock is back in service and automatically lines up with the hot wet hole before it.
Before going any further, Mitchell asks, "Are you sure about this baby sister? Once we go here, there isn't any coming back."
In answer, Kelsie pushes herself onto the tip of Mitchell's cock so the head broaches her willing hole. "Take me, Mitchell. I'm in love with my hero. You deserve the prize before you. I give myself to you completely."
Mitchell slowly, for both their enjoyment, pushes in. When he bottoms out, they both moan into each other's mouths as their lips lock together again. Mitchell takes his time pleasuring his sister and himself. They couple for nearly thirty minutes before he is close and tells her.
"I'm going to cum again, Kelsie. Should I pull out?" He searches her face for fear or doubt. He finds a love-filled smile, and her heels push into his butt, answering his question. Kelsie then kisses him again, waiting to be complete and filled with her brother's love essence again. With a handful of strokes more, Mitchell buries himself in his sister's hot wet love tunnel and begins spewing gobs of cum at her rear wall.
His hot cum sends Kelsie over in a spectacular fashion. Her back arches hard, and she moans loudly, "Oh, Mitchell!!!" Then she keens out her pleasure as her orgasm sends her flying into ecstasy.
Mitchell is immediately addicted to making Kelsie cum. He looks down at her face and thinks, 'I have to see that as often as possible. She's so beautiful like this.' He then catches sight of her hard little nipples and realizes he hasn't sampled them. He leans his head down and lip locks one, and gently sucks the nipple while tickling it with his tongue--the additional stimulation keeps Kelsie's orgasm at a fever pitch. He switches off after a minute, giving it the same treatment before letting Kelsie's orgasm retreat, and she comes back to him.
When her back returns to the bed, Mitchell lays down atop Kelsie for a minute, giving her lips light pecks. When her eyes blink open again, he tells her, "I love you too, Kelsie. My baby sister is my girl now if she'll have me."
"God, Yes," she answers with a huskiness to her voice. They kiss again, tender at first, then more passionately. When the kiss breaks, they both grin and know this is something to protect and continue for as long as they can, forever if possible.
"I know you love me now, too, Mitchell. Will you fuck me now and show me your passion for us?"
They grin broadly as they begin to fuck in as many positions throughout the remainder of the afternoon. In the end, Mitchell fills Kelsie with three loads into her pussy. He never asked if she was protected, and Kelsie said nothing. They manage to get a shower together and clean up before their parents each get home from work. The silly grins about what they had done catch Mom's eye, so she asks about it.
Mitchell answers for them and says, "We spent the afternoon getting silly and remembering past summer days. It was a perfect afternoon, that's all." Kelsie just nods with a little titter. She shrugged and finished the dinner they shared.
After the kids did the dishes, they decided a walk would be a good idea. They strolled their neighborhood, discussing the future, holding hands the whole time.
