Of course.

You scramble to your feet and shout, "Wait!" But Shelly pays you no attention, continuing her flight deeper into the woods, moving fast despite her awkward gait, favoring her left side. Leaving your equipment behind, you chase after her.

As you slip between the first set of trees, you feel your heart thudding faster than ever before, its heavy beats shaking your chest, and very little of its pace has to do with your previous physical exertions. You'd hurt your sister and potentially broken the relationship that had just been forming between the two of you. You'd miscalculated how she would react. Even though you'd acted in the heat of the moment, that's not an excuse. You should have been able to hold back and not **** your feeling on her. I only hope I can fix things, you fervently wish.

The forest thickens the further you run, undergrowth and young trees filling in empty spaces, tugging at your clothes as you squeeze through the narrow openings. It's difficult to see more than ten steps ahead of you. The thick leaves sends shadows rippling everywhere and you have to be careful not to stumble on hidden roots.

It's a surprise when you break into a small clearing and you almost rush through before you realize that Shelly has stopped here, her back pressed against an oak tree. Tears are pouring down her face and they double down when she sees you, standing just a couple of feet away from her. Your reaction is immediate--your little sister is in pain. You step forward and wrap your arms around her in a tight embrace. She resists at first, her body rigid. But then her resistance crumbles and she leans against you, her tears soaking your shirt, and returns the hug. For a while you just stand there, sharing your strength and letting Shelly work through her emotions.

Finally, with a sniffle she raises her head. "I'm so sorry, something's wrong with me," she says, her voice the embodiment of sincerity. "I've been teasing you so much recently, with my yoga and in the car and now with this tennis trip. I don't know why I did it exactly, but I liked flaunting myself and getting a reaction out of you but I never meant...." Her words trailed off, but you understand where she's headed. You've been confronting your feelings toward her for longer than she has and she may not be fully aware of what she meant to happen. Maybe I can help her along.

"Shelly," you say, capturing her beautiful blue eyes with your own. You see sorrow there, combined with a tinge of fear, but also trust. "I know what kind of movies you have on your computer." Her mouth drops open and you feel her tense, getting ready to flee again. You hold tight, refusing to let her do so and after a short struggle she looks up at you again. You continue gently. "Maybe the past few days have been influenced by that."

"I'm so sorry," she apologizes again, but you stop her before she can add anything more. You pull her close.

"Do you think I would have done what I did at the tennis court or what I'm about to do if those movies bothered me? Or if I didn't share your same feelings?" You lean forward and kiss her again, softly, letting your lips rest against her's as lightly as a butterfly.

A second passes. Then two. You can feel her heart beating, quickening as time passes until it's fluttering to fast to count. You can almost feel the chaos running rampant through Shelly's mind as she is once again surprised by your actions. Warring parts of her brain are fighting a war to decide whether she'll give into her emotions and kiss you back or let her reason rule and push you away.

After a minute, she kisses you back.

All of the pent up frustrations and worries burst like a dam and she pushes herself against you, her big, soft tits squishing against your body in a way that you'd only dreamed about and you moan excitedly. Her hands roam across your back, their gentle pressure pulling you closer. Then she dips them underneath your shirt, rubbing them along your skin in fiery lines. Meanwhile, your own right hand dips to her thighs and runs circles across her smooth skin and pushing her the hem of her skirt higher and higher. Her inhibitions loosened, your sister groans and squeezes your own ass, grinding against you hard enough to feel the erection that's growing in your shorts.

The next line is crossed almost simultaneously. Just as your hand slips even higher to the delicate red panties beneath her skirt, your sister's hand slides to your front and slides along the hardening length of your still hidden shaft. Both of you shudder at each other's touch. You slide her panties to the side and find her pussy lips, running the tip of your finger along their ridges, pausing briefly to flick her clit as you pass by. Shelly breaks your kiss with a whimper.

"Oh fuck, that feels so good. God, I want this so much, keep rubbing my pussy, big brother and make me cum!" Her breathing is ragged as you comply, dipping the tip into her wet tunnel and wiggling it around. "Fuck, fuck, fuck! I need to feel you too!"

Frantically, Shelly grabs at your waistband and tugs your shorts down, your dick exploding from its confines like a rocket and just as big. She gasps when it comes into full view and she gets her first handful of brother-dick. "Jesus H. Christ, I knew it had to be large but I've never see on this big. It's nearly as big as I dreamed it was...." She breaks off as she realizes that she's been dreaming about your cock, but you just give her a big grin and add a second finger to her cunt, twisting and pushing until you find her g-spot and driving all concerns from her thoughts. Her own hand impulsively glides along your meat, jerking you off with surprising delicate technique.

For a few minutes, the forest is silent except for the sounds you both make as you pleasure each other. Thoughts of how you and Shelly have arrived at this point are pushed aside, and only your passionate, lust-filled feelings are allowed to reign. You've never been this turned on before, even in your dreams and from the way your sister is squirming, you doubt she has been too.

"Unh, unh, it's coming, it's coming," she cries and slams her crotch against your hand, driving your fingers to new depths inside her pussy. Her eyes shut as a massive shudder shakes her like an earthquake, then smaller aftershocks compete to see which can make her lose her balance. Her hand grips your dick hard, but not unpleasantly so, and you lean into your fingerfucking, pushing her orgasms to last even longer.

She leans back against the tree, her strength draining from her. She opens her eyes, see yous watching her reactions and she smiles widely. She shakes her head, sending her blond ponytail whipping back and forth. "I don't know if I've ever had a stronger orgasms," she says and lowers her head, finding your erection still poking from between her fingers. Her mouth spreads even further. "Now it's my turn."

She drops to her knees, unconcerned at the uneven surface of the forest's floor, and a couple of synapses misfire in your brain. Holy fuck, is she really going to...?

Before you can even finish your thought, your sister wraps her lips around your dick and slides a few inches down its length. You're immediately sent to heaven. You've dreamed about this, imagined it, but none of those experiences compare to the real thing. This isn't the dream world where you can manipulate reality, this is the real world where your actual sister is giving you the blowjob of your life. Her mouth forms a perfect tunnel for your shaft, moving along your prick like it was always meant to. Add to that the view you have looking down at Shelly, with her low-cut top leaving breasts to jiggle and threaten to burst out as she sucks you off.

Maybe sensing your gaze, or maybe just because she can't control herself, your sister brings both her hands to her massive chest and mashes her tits between her fingers. It's the kind of action you've seen in pornos and thought 'What's the purpose?' but in the moment, seeing your sister play with her melons while she pleasures you is more than you can take.

"Oh shit, I'm about to cum," you warn Shelly, being a good brother. She nods and shoots the tip of her tongue to the glans just below your penis head, licking it furiously. Your balls explode, sending jizz deep into the back of your sister's throat, where she guzzles it down just as fast as you can shoot it. You see her throat working overtime as she swallows load after load and you're impressed by her talent. When you're finished, she gives a few more long licks to make sure your cock is clean and then stands back up.

She kisses you deeply and then pulls away. "I love you," she says, simply.

"I love you too," you respond, meaning every word. "We should probably go make sure our stuff hasn't been stolen." Shelly nods. You pull your shorts back up and your sister readjust her panties. When you're both back in an acceptable state, you take Shelly's hand and walk back toward the tennis courts, together.
