Bored Little Girl/Pool2a
After what feels like an eternity, Jackie finally walks up the stairs to go lie down in the sun. You can hardly wait to straddle the jet without worry, but you still have to wait for your sister to dry off, so for now you just grab the front of your swimsuit and pull up gently, adding to the pressure on your swollen bits.
As your anticipation is reaching a breaking point, Jackie finally folds a chair out flat, drapes her towel over it and lies down on her tummy. She leaves the music on, which is probably good since she won't hear you breathing heavy or moaning a little bit. As soon as you can see her settled you pull yourself close to the pool wall with both hands and ever so slowly slide your hips sideways until you feel the water hitting your pussy. It feels so good you want to cry out, but you bite it back as you hold your tender pussy in front of the jet for as long as you can. The pressure becomes too great after only a couple seconds, and you pull yourself up so the water just shoots between your legs. You fold your arms on the deck. With a long sigh, you let your cheek come down to rest on them and gently wave your legs as the flowing water tickles your thighs.
You look over at your sister and see she is still facing away from you, clueless to what you've started doing. With her legs stretched out her butt sticking up looks really nice and you imagine going over and playing with her cheeks. Grabbing them, jiggling them, even spanking a bit. You knew most people would be weirded out that you're attracted to your own sister, but it's never been something you've been able to control. You had realized from a young age that you were attracted to other girls, and always loved looking at older girls and their big boobs and asses like you hoped you would have when you grew up. As soon as your sister started developing physically you couldn't help but wonder what she looked like naked. When you realized how good these thoughts made you feel, Jackie became a frequent subject of the fantasies that float through your head while masturbating.
But now you hardly had to imagine anything. Jackie was laying out for you to ogle with only a paper-thin piece of fabric covering her. As you gently lower yourself back down so the water can resume blasting your excited clit and swollen labia, you admire the way the fabric of her bikini clings tight to her cheeks and disappears between them. You smile and gyrate your hips as your arousal grows and suddenly surprise even yourself with a gentle moan.
Your sister shifts and for a moment your heart pounds as you think she heard you. You quickly pull yourself higher on the deck so the water isn't hitting your pussy any more and prepare to swim in the other direction, but then you see your sister is just rolling over, still uninterested in what you're doing. She grabs a sun hat she had brought out with her and places it over her face. Excellent. Maybe she'll even fall asleep.
Maybe she'll have a wet dream. The naughty thought invades your head. The way your sister is laying, with one leg extended all the way out and the other bent and falling away from it slightly, have you a great view of her pussy. The gusset of her suit gently dips into her slit, creating a cameltoe that outlines her puffy labia majora beautifully. You let the water start pounding your privates once more and this time hold it there as your cheek hits your folded arm and you stare between your sister's legs. Your breathing speeds up and your head starts feeling light. Almost out of your control your legs start tensing and releasing, tensing and releasing, pushing your pussy momentarily closer to the jet nozzle. You shift so the flow of the water is right on your clit and immediately you're taken over by an orgasm. Your legs tense up again, you shake, and it feels like your heart is trying to break out of your chest. You don't let yourself make a sound, but your mouth is stuck open in a silent scream of ecstasy. If your sister were to see your face there would be no mistaking what you were doing.
As soon as the climax is over the pressure on your pussy turns to pain, and you quickly move over beside the jet, letting your head rest onto your folded arms again. For a while you just lie there and let the afterglow wash over you, a tingle between your legs and the sun beating down on your back. You slowly close your eyes for a moment, blocking out your sight to focus on the feeling of your whole body electrified by orgasm, then let them open again to be greeted by the sight of your sister's lovely lips. You're in paradise.
You aren't sure quite how long you stay there like that. You feel like you could stay there forever as waves of pleasure wash over you. However, naturally, the waves recede over time and you come back down to Earth. Jackie takes the hat off of her face and slowly sits up, then looks over and smiles contentedly at you, which you return with an innocent grin of your own. As far as she knows you had just been swimming and splashing around like any little girl. As your sister wordlessly walks into the house you do paddle a couple more quick laps around the pool before getting out yourself. You quickly dry off and, as some thick clouds were rolling in, run inside before you get cold. As you do this, thoughts of Jackie's butt, pussy and lovely little boobs filled your head. There was still quite a bit of the afternoon left...
