My cousin seems to be in great shape after spending the night before sleeping, so I offer him a bike ride.
    - Be there at noon, my mother says.
    - Don't worry, mom!

We'll ride for a few minutes without a word.

    - Where are we going?
    - You'll see, trust me.
    - I'll be right behind you.

At first, I ride quietly, sitting on my skirt, as befits a well-behaved young lady.
At the first bend, I lift up to clear my skirt and allow it to fly around me, sometimes revealing my panties. André takes care to stay behind me, which makes me smile. Sometimes I pedal like a dancer, for no other really obvious reason than to give him a nice show. I'm sure he's red and excited by the sight of my buttocks, which must pop out of the fabric as I pedal. A building I know well appears.
    - See that barn? That's where we're going. Come on, we'll stash the bikes back there.
Let's go inside. There's straw, old farm machinery, a few tools, and a ladder that reminds me of a vacation goes upstairs where there's some hay left. I climb the ladder offering a shameless view of the countryside that André can't fail to notice. At least I hope so.
It's no longer the little girl's thighs that he glimpsed a few years ago when we were climbing trees, but a woman's thighs, and the little ribbon of panties now hides something quite different from what it used to be... He comes up behind me, his heart a little beating.
We are now in the barn, standing opposite each other. What happens now? I have to dare...
    - Undress me.
    - — …?
    - Come on, come on, don't be afraid!
He's unbuttoning my blouse, a little shaky and clumsy, he slides one arm, then the other. I'm in my bra in front of him, a burn goes up to my cheeks. My belly throbs. He stays in front of me, panting and dazed.
    - Keep going.
He hesitates for a moment, probably between continuing by the skirt or the bra. He finds the skirt zipper, opens it, slides the garment down to the ankles. He clears his throat. Finding myself in my underwear in front of him makes me feel everything.
    - Turn around, he asks me.
I turn around, he unzips the bra, avoiding touching my skin with his fingers, too bad...
As if this contact should electrocute him. I turn back to face him again.
    - What do you think?
He slides the straps over my shoulders, clears the cups and uncovers my breasts, all white, with swollen areolas, the tips harden.  He looks hypnotized. There is no doubt I give him a beefy effect. It's much better than the first time. The fact that he's participating...
    - Keep going, she blows.
He kneels down in front of me and pulls my panties down around my thighs, too fast, without any restraint. I'll have to teach him to be softer and to do it in a more... suave way... He is now face to face - if I may say so - with the triangle of my hair, a mysterious and dreamy place. He doesn't move, fascinated. I take a step back.
    - Look, look, look, look, look.
His amazed but greedy look makes me feel all hot, as if a fever had taken hold of me. I feel my lower abdomen getting wet. I turn slowly on myself to let him take advantage of all the angles: the profile showing the curve of my breasts and buttocks, the back that reveals the shape of the body: shoulders just wide enough, a bust that tapers down to a fine waist. And then the fall of the kidneys, the roundness of the back, the buttocks, with this furrow which seems to modestly hide some treasure... My thighs, which have the power to protect and forbid or on the contrary to reveal and offer... And, in front, these breasts for which one imagines a thousand caresses and a thousand sweetnesses, the waist, the belly and its end, below, with this almost trivial triangle of hair, the last rampart against the inaccessible.
I'm naked, for him alone. I offer this body to his gaze. It's hard. His erection through the fabric is the measure of the gift I give him. Ah... Dear cousin ...
    - Now it's my turn.
I don't stay behind and undertake to undress him in turn. Without hesitation, I take off her shirt... her shorts.  He stands still not believing what's happening to him. I mark a time in front of his briefs deformed by a monstrous erection. I start to pull him down, being careful not to catch anything, I wouldn't want to hurt him. I mark a new and brief pause in front of the object which is released from the underwear. It is more impressive than yesterday morning.
A car arrives at this moment. We hide naked in the straw and make no noise so as not to be discovered. A couple between laughing loudly.  I recognize my brother and his girlfriend. They make love fully dressed in front of our eyes or rather our ears.  Andre and I avoid looking at each other. The couple leaves after fifteen minutes.

We're left here... congested, but bewildered. We look at each other. With his underpants around his thighs, he looks ridiculous. We pretend to laugh about it, but the unseen scene was still exciting, and the rest of his erection regains strength in front of my nudity.

    - Come on," I said, "we have to go. If we're late for dinner, it's going to be a fuss.

    - You can't leave me like this," he said in my ear. Take it in your hand.

I reach out my hand, but barely, I finally go. No, you're not... Not yet.
    - No, I don't dare.
    - Yes, take it, please!
    - I don't know how!
    - Take it, I'll help you.
My hand is coming forward. I touch the sex. Feel the skin, it's so soft, it doesn't feel like it. My fingers surround the swollen limb and start to squeeze gently.  He wraps his hand around my hand to guide me, stays still for a long time, and starts to move back and forth. I take my hand away. I don't know if I finally want to go any further.
    - No! I don't!
    - Yes, take it. Come back!

He takes my hand back, gently overcomes my resistance, and places my fingers around his penis again, clasped by his own hand. He takes it back. This time I let myself go, and soon I need no further guidance. My movement is less hesitant, becoming firmer and fuller, until long spurts of semen spurt out and get lost in the hay.

    - So that's it, I thought to myself...
The beginning of my education is done. I was a little scared at first. But the sight of his face blossoming and his delighted smile gave me confidence. And then no risk of getting pregnant. Sophie explained it to me well. That's not how you make babies. Today I'll have learned how to jerk off a boy and with success, considering all the sperm that spurted out. Maybe I'm good at it. Anyway, now I know what a jerk-off is, I've seen one with my own eyes...
But it didn't give me as much pleasure as when I caress myself. Next time it'll be his turn...
