Wait for the rain to end

You set Rachel onto the ground, laying her up against the wall. While you are kneeling in front of her. Slowly you retrieve your hand from her dripping cunt. You then stick your middle finger into her open mouth. Her eyes refocus and begin to clean herself off of your fingers, slowly and sensually sucking each wet digit.

"Mmm, all clean," she says, finishing.

"Good, remove your panties," you tell her, she obediently follows your order.

She pulls her now soaked panties off, and set them aside. Meanwhile, you remove your pants, with your large member springing forth to meet her; slapping onto her now bare mound.

"I think we have a little while till the rain stops," you tell her, "and I plan to fuck you until it does."

"Yes, please, I need it. Give me your cock big brother," she moans.

You pull her legs around your shoulders, causing her to bend enough that her breasts cover her flat stomach. You line up your cock with her lips, thrusting into her; you are met with little resistance.

"YESS!" Rachel screams in pleasure.

You feel her passage slick contort around your cock. You notice as her backbends, causing her to hunch over as you plow her into the wall. You lay your lips upon hers, her warm, humid breath tickling your face. Her tongue is searching for yours while her lips suck at your own, making lewd sounds; you can taste her cum on her lips, the taste is intoxicating.

You begin to thrust in and out, each inward thrust matched by a loud "Yes!" from Rachel, sending vibrations into your kissing mouths.

You feel her thighs titch as she curls her toes at the ravaging of her pussy. You pull yourself away from the kiss, unleashing her moaning.

"--es,... Aaron,... please... please... don't... stop," she moans.

You watch as her large breasts rock back and forth, this time rolling into her face, blocking her moaning every couple of seconds. You reach up right above where you a fucking, teasing her clit. This is enough sending you once again over the edge; her body gives out as she weakly moans as you continue your ****. Her cunt is drenching your cock in her juices.

She begins breathing, yet you do not let up, determined to bring your little sister as many orgasms as possible; your hand is continuing to tease her tiny button. Her moans begin to pick up the pace again.

"Oh, yes," becoming "yes, yes, yes."

Soon you feel her approaching another orgasm, you don't stop, and you don't dare slow down, as she cums yet again.

"OH!" she moans loudly.

You take you slick again hand and reach up running the wet digits around her areola, and tugging at her nipple. Halting the movement of the breast you are using, while the other one continues its up and down motion.

You feel yourself approaching orgasm, yet you try to calm yourself; determined to give at least one more orgasm. You breathe in sharply continuing your thrusting. You hear your sister's hands flail as they try desperately to find something to hold onto as another orgasm rocks her body; finally, you thrust into her, pumping your load into her writhing pussy.

Slowly you withdraw and watch as your cum comes flowing out of your sister.

Looking up you can still hear the rain impacting on the top of the shuttle. Your sister is gasping for her breath, you begin to get your cock hard again.

"That was great," Rachel purrs.

"What?" you ask rhetorically, "I'm not done yet, has it stopped raining?"

You grab your sister's legs, turning her over onto her hands and knees; she lets out a surprised gasp, as you thrust your cock back into her, now slimy, cunt. Quickly, you begin your former pace.

"Oh, yes," she moans again, happy at your continuation.

You begin to thrust in and out, grabbing at her hanging breasts and feeling the soft tissue again. You tease the sensitive nipple anew; driving your sister's voice every higher. You sense her arms give out as she has her fifth orgasm.

You continue, noticing that a clear pool of fluid as built upon the ground, directly from the number of times you have caused her to cum. Your sister's tongue now hangs limply out of her mouth, a strand of saliva reaching to the floor; as she thoughtlessly approaches another orgasm. Yet you continue your ****, driving yourself deeper into her soft mound.

Her body begins to shake again as another orgasm rocks her body. She begins to collapse, her body turning completely into jelly; as her muscles disregard any signal her brain sends, all but to be fucked. You feel spurred closer to orgasm at looking at your results on your sister, thrusting even faster, now the sounds of slapping flesh drowned out the sound of the rain. You feel Rachel rocked by another seventh orgasm, as you push yourself deeper, finishing yourself for the second time into her cunt.
