My Wife’s Hot Younger Sister [M/F]

My wife Julia has been fairly estranged from her Mom for large parts of her life. They’ve always just rubbed one another the wrong way and have found it best to keep a safe distance between them. Still, a few times a year we’ll make the trek out to see her Mom and Julia’s half-sister, Autumn.

Last August, Julia and I begrudgingly opted to make the hour-long drive to attend her Mom’s 50th birthday party. We weren’t jazzed about it, but felt we should get in our time now and maybe skip Thanksgiving there in a few months.

It was sticky hot that day. Julia’s mother Anne lived in a cookie-cutter neighborhood just on the city side of the boonies. It was simultaneously nice and trashy. Regardless, she had an in-ground pool which was heavily occupied with party goers due to the late summer mugginess. After Julia and I grabbed a few beers, we made our way to the edge of the pool. That’s when Autumn emerged from the water, lighting up at our arrival.

“Y’all!!” she exclaimed, running towards us, sopping wet. Her breasts, a very nice middle C cup, bounced lightly as she whisked our way. Her cherry red bikini top perfectly showcased her erect nipples. She hugged us both at once, her pool water-covered body instantly drenching our shirts. We hugged her back lovingly. I could feel her left breast touching my chest and my cock stirred furiously.

“Hey babe!” Julia smiled. “Big turn-out, eh?”

“Y’all *so* many peeps came today!” She stumbled a little, clearly a bit inebriated. I swiftly moved to catch her balance and lightly embraced her shoulder and the small of her back.

“Woah, girl! Careful.” I said. She looked at me and smiled sweetly. “Such a gentleman! I do believe he’s givin’ me the vapors!” She fanned herself comically. We all laughed.

Autumn is a tiny little thing. 5’ and petite in frame, but possessing a lovely curvy ass. She has long, chestnut brown hair and enormous green eyes. Disney-esque monstrosities, really. One her sexiest features though, are her improbably pursed lips. She has a distinct cartoon vibe that is just sexy. A solid 10 years younger than my wife, Autumn is in peak young adult form.

Autumn saw some friends then and jetted away. Julia grabbed my hand and we schmoozed a bit, taking to people we knew and avoiding those that we didn’t. Julia was always a bit on edge when we came here, so drinks flowed freely. Before we knew it, we were fully tipsy.

The party started to wane after a few hours, and most of the attendees had departed long ago. Normally, Julia and I would be leaving too, but our all-day drinking had left us anxious about the long drive home.

“Oh you guys should stay over!” Anne said, heavily slurred. “I make you pancakes and fat back bacon for breakfast it be so gooooood!” She was plastered. We all were. Laughing ensued.

Julia looked at me “Is that okay?” she mouthed. I nodded and smiled reassuringly. I was in no state to drive, and bacon sounded great.

The night ended shortly thereafter, everyone retiring to their rooms or a nearby couch or wherever. Julia and I got the guest room, and while normally this kind of drunkenness would lead to steamy sex, we just didn’t have the energy and promptly passed out.

When I awoke an unclear time later, I could feel a hand on my leg. I turned slightly to look at Julia, but her back was toward me. It couldn’t have possibly been her, she was too far away. The hand moved softly up and down my upper left leg, gently caressing. I was in only my briefs and the covers were bunched so that I could not see who the hand belonged to. I sat in silence, unmoving.

The small hand slowly worked its way up my briefs and began slipping a finger underneath the outer band. One finger moved across the skin there seductively. It felt amazing, and my cock quickly sprung to full attention. I looked to Julia again, but she was fast asleep. Her shoulders rose and fell with the breathing of deep sleep. Who was doing this?

The fingers moved toward the outline of my cock, now rigidly pinned beneath my form-fitting briefs. I distinctly felt a finger slide smoothly over my cock’s head, which in turn delivered a dab of pre-cum. The hand gingerly took my cock through the briefs and gave it a little squeeze. It felt incredible. My hips reflexively thrust slightly in response to the touch, and I felt the hand swiftly pull away. I closed my eyes and pretended to be asleep. I felt the covers being pulled down and could feel a light pull on my side of the bed. It felt like a head peeked over the covers, but I couldn’t be sure then.

After a moment the hand came back and resumed its course of light teases. The hand began to run the length of my 9” cock over my briefs, the fingers looped halfway around. I was getting so hot and my pre-cum had fully soaked the area surrounding my head. I really wanted to cum, so I opted to make a bold move: I reached down and freed my cock. I felt it whip against my stomach like a rubber band, making an audible slap as it did.

There was no reaction from the mystery hand for a short while (it felt like 5 minutes but was probably 30 seconds), and then I heard a light, feminine giggle. It was Autumn. I could tell explicitly. I lifted the covers a little and looked into her freakishly large and insanely seductive eyes. She bit her lip and smiled at me devilishly. She held up one finger to her lips and silently said “shhhhh.”

With that, she moved the covers to bunch them away from me, inadvertently creating a border between us and Julia. I caressed her face once and she turned her head into it, closing her eyes in a blissful moment of acceptance. I turned my body onto its side. She immediately embraced my cock by the base and put her tongue to the tip, maintaining eye contact throughout. She lightly tongued my hole and pulled away slightly, trailing a sinewy line of cum as she did. My cock was engorged to an almost uncomfortable degree, springing forward like a missile.

Autumn, still looking me dead in the eyes, opened her mouth wide and began taking me in. While I could feel her breath on my engorged penis, she hadn’t fully clamped down yet. She managed to get about halfway down my length when she fully put her mouth down on it. Her puffed, pursed lips looked heavenly as they rested on my shaft. Sucking slightly and licking at the same time, the saliva fully saturated my cock almost immediately. She brought her hand up to where her lips were, and sucked her way back up. Now working in tandem, her lips and hand began moving up and down my cock rhythmically. She was insanely good at this; far better than her sister.

I could feel myself getting close to cumming, so i began to do the thrusting myself. She immediately sensed this, and bit down lightly on my head. The sharp feeling was surprising, but I right away understood her motivation. “Not yet,” she mouthed at me, circling my cock’s head with her tongue.

She pulled my briefs off of one leg and began licking down the length of my shaft to my balls. One after the other, she would lick, suckle, nibble on and release my balls. She was jerking my cock lightly, taking care to squeeze the tip and stop me from orgasming too soon. She began to lick beneath my balls, working down my taint. Still jerking my cock, she licked along my taint and began to flick my asshole with her tongue. She licked around the perimeter, wetting it. Suddenly, she thrust her tongue into my ass and began jerking faster. My cock still sopping wet from her mouth, I was in an acutely sensuous state, barely containing my orgasm. She tongued my ass in and out and stroked my cock in a staggered time with her tongue work. It was masterful and I didn’t think I could hold out much longer.

Sensing this, she stopped all of her motions at once. I sat, tensed, about to explode cum all over myself. She smiled coyly and lightly pinched my cock’s head again, slowing me down. She licked up the length of my shaft from the balls to the tip, and at the same time began gently putting her finger into my lubed up asshole. She engulfed my cock in her mouth as she entered my ass simultaneously, and I was at the edge of a full-on explosion. Quickly, she sped up her pace with her mouth and finger and I couldn’t hold out any longer. With one deep thrust, my cock erupted into her warm mouth. Jet after jet of thick, warm cum released into her wet mouth. I heard her purr as my cum filled her and she continued to suck and finger me. She slowed her pace a bit as my cock began to shoot less and less cum, and began sucking just the tip and squeezing the shaft to get out every drop. Her pace slowed to a crawl as she got the last bits of my semen, and she crawled up to me with her mouth closed. When she was close enough so I could see, she opened her mouth and showed me the large wad of cum that sat there on her tongue. She stuck her tongue out, covered in cum, and one strand of it loped down toward the floor. With a quick, quiet *slurp* she sucked it back into her mouth. She made an exaggerated gulping motion as she swallowed, winked at me and opened her mouth again to show me that it was all gone. She kissed my cock a few more times, sucking out a few more drops of my sperm and drinking that down, too.

She put the covers back over me and stepped up from her kneeling position on the floor. She bent down and kissed me passionately on the lips once. I looked over at my wife, still sound asleep.

“I love when you come visit,” Autumn whispered into my ear, then she quietly slipped out the door.
