Autumn Falls

"Are you sure you wanna do this here Autumn?" You asked your younger sister as you scratched your head and glanced around to see if there was someone nearby. It was fortunate that the place is an abandoned changing room that was located around the corner. "You know fucking someone related to you isn't the same as fucking a stranger or a boyfriend. You're lucky that I would jump at the chance to fuck your hot body." You gave a smirk as Autumn blushed but smiled as well.

"I know it feels wrong Y/N, but I just can't stand my classmates mocking me about being a noob in sex and I wanted to prove them wrong." Autumn said as the two of you began stripping down to your underwear.

The reason for the current event happened earlier that morning. You were playing Honkai Impact 3rd on your laptop when Autumn came to your room looking uncomfortable for some reason. You asked if she was being bullied or if someone is sending her death threats, but Autumn said no. Instead, she asked out of the blue if you could have sex with her which nearly made you failed the mission at hand.

When asked why, Autumn simply said that she was jealous about her friends who had sex and often teased her about her being a virgin despite the fact she had her hymen broken before with her ex. And also the fact you had experience with sex as well with other girls you had during college. Since your family is going to the beach, you agreed but only when you find a secure spot to fuck.

After stripping, the two of you were nothing more than in your birthday suits. Your sister sporting an impressive G-cup tits and her pussy which she clearly shaved for this moment. Meanwhile, Autumn looked at your limp 11-inch cock dangling between your legs as she is amazed by how big you are.

Without saying much, Autumn fell to her knees and used one hand to stroke your cock which you gave a small sigh of relief as her warm hand moved up and down on your manhood before she held her G-cup tits between your fat cock and mouth near the tip as she gave you a titjob and blowjob at once. "Ooh fuck, I almost came from your hot mouth Autumn." You informed her but withheld as your hips moved in a back and forth motion, watching your cock disappear into her breasts before the tip came out which she licks.

The sounds of slurping and flesh smacking echoed throughout the area and only because it was abandoned and secluded that no one heard as you combed through Autumn's hair as her tits felt very soft against your cock and her tongue licking the tip as the hot incestuous intercourse continued. Eventually, you groaned and tensed up as you came on Autumn.

Cum came flying out of the tip as it spilled on your sister's tits and in her mouth. She gagged in reflex but swallowed down the salty yet tasty liquid as she took big gulps as if she was drinking water. When it was done, you pulled out and Autumn panted from the climax, using her fingers to scoop up traces of cum on her tits and put it in her mouth.

"Wow, I never knew it tasted it this good Y/N." She giggled as you chuckled and watch her lick the last cum from her mouth and stood back up. Looking down however, Autumn is surprised that you are still hard despite cumming a lot. "Due to my past experience with other girls, it takes a lot to me make cum Autumn." You grinned at your younger sister.

Giving you a wink, she gently pressed your shoulders down as you sat on on the the benches and watch with amusement as your younger sister got on top of you and straddled your hips, her pussy grinding against your cock. Autumn took a deep breath before sinking down on your shaft. The two of you gasped as you felt how tight she was and how you were big inside Autumn.

"Fuck!" She cried out and arched her back as she began bouncing on your cock, you helped her by wrapping your arms around her waist and began thrusting up to meet her hips. Her plump ass cheeks clapped against your hips as you and Autumn had incestuous sex. Her swaying G-cup tits bouncing in your face proved too tempting to ignore and latched your mouth in one of her nipples, sucking on it as if you were a baby.

"Mmph, I almost forgot. you have a thing for girls with big tits." Autumn moaned as she used the walls to stabilize her body as she continued to ride your fat cock, her pussy sucking it in liek a vacuum as you feasted on her breasts. You then sneaked one finger into her asshole and inserted it, making her gasp.

"Oooh, you sneaky bastard Y/N." She panted as you wiggled your finger in her ass as you continued to thrust into her pussy while simultaneously giving Autumn an anal fingering. Eventually, the action caused Autumn to cry out as she came on your cock, her pussy clamping down as she squirted love juices and you grunted, cumming deep inside her snatch. Semen burst out like a flood as you creampied your own sister as your cock kept twitching as excess cum spilled out of her stuff pussy.

After resting for a tow minutes, you flipped Autumn over and began pounding her ass in a mating press position. You cock drilling deep into Autumn's asshole as she moaned crazily, her tongue rolling out and her eyes rolled into her head as you fucked her raw. "Fuck, your ass is as tight as the last bitch I've laid with!" Your groaned with lust as you kneed her G-cup tits with your hands as you massaged her breasts thoroughly.

You leaned in and tongue kissed Autumn as she moaned into that, your tongue clashing with hers as you pounded your busty younger sister with the intent of ruining her for other men to fuck. Semen spilled out from her pussy as the result of your hard thrusts in her. Sweat poured out of your bodies nonstop as you continue to ram into Autumn with until she was full.

Ultimately, you and Autumn moaned at once and came simultaneously, her pussy squirting all over as you exploded inside her ass. Her anal walls constricting your cock as semen flooded her backside, filling it with hot liquid. Autumn shook with pleasure as you came in her tiny asshole, feeling your cock twitch every time it fires another round.

All things must come to an end though, as your cock went limp and slipped out of her ass, this time cum stayed where it is as you laid on top of Autumn. Brother and sister panting in exhaustion

"I take it that's good enough for you?" You asked which Autumn nodded.

"Yeah. Just let me get a picture." She said and reached for her phone in her bag and positioned for a selfie. You and Autumn smiled and made a peace sign as the phone flashed for the aftermath of the incestuous sex.
