I have known my wife's sister since she was ten years old. I have been to her school plays, birthday parties, and graduations. She was a bridesmaid at our wedding, and I watched her grow from a girl to a woman. By the time Amy hit her twenties, she had become this sassy, sexually charged woman who enjoyed teasing men to their breaking point. She used her body as a weapon, wearing outfits that barely covered her slender frame. She loved loose-fitting tops, so when she bent down, you could see what colored bra she was wearing. Sometimes she wouldn’t wear a bra at all. I always treated Amy like a little sister, but our childish banter took a more adult-like flirtation once she blossomed.
Amy was shorter than your average female, standing five feet three and weighing just under one hundred pounds. Her breasts were not very large but fit perfectly with her slim figure. Her ass was perfect in any person's imagination, the kind of ass that you just wanted to bury your face in. Her hair color constantly changed, depending on her mood, and flowed past her shoulders to the middle of her back. She was every guy's wet dream.
On the day of the barbecue, we got to my in-laws' house around noon. We were always early since it was tough lugging two kids around. My father-in-law was already standing at his outdoor bar waiting for me. After a quick greeting, with a handshake and hug, he handed me a beer like he customarily did at all his get-togethers.
Three beers later, an hour had passed. Most of the guests arrived except my sister-in-law, who was always late and lived for the stunning entrance so she could be the center of attention. The beers had gone through me, so I excused myself for a quick bathroom break. I rounded the hallway corner, passing the bottom of the staircase, when I heard Amy’s voice.
“Hay sexy,” she called out from the top of the staircase.
“Hey, beautiful,” I responded, glancing around to make sure it was only the two of us.
She looked stunning as always, wearing a tiny white skirt that barely covered her private areas but from the bottom of the staircase I could see her little black panties underneath. She made her way down the stairs and met me at the bottom. Amy leaned in to kiss me on the cheek but made sure to press her entire body into me, giving me a chance to feel her breasts as they pressed into my chest. Her belly just below her navalpushed into the bulge that was growing inside my pants.
“Oh, I see somebody likes my outfit,” she said with a smile.
As she turned away from me, she quickly lifted the miniskirt,exposing the black thong she was wearing underneath. She turned her head back to me, whipping her hair around before giving me a wink. Her ass was perfect, and the vision of that little black thong running between that tight-ass crack would be stuck in my thoughts for the rest of the day.
“Have fun with that in there with that thing,” she playfully giggled.
I quickly shuffled into the bathroom, still thinking about how her ass would look if she were bent over a table with a hard cock in her ass. Once inside the bathroom, I had to calm myself down and wait for my boner to subside so I could pee. Eventually, I was able to redirect my sexual thoughts, finish my business in the bathroom, and return to the barbecue.
Amy sat down at the table directly across from me, laughing and chatting it up with everyone around her. It was tough not to stare at her as all I could think about was that tiny black thong sitting snugly on her twenty-year-old pussy. My mind started to wander as I imagined what it would be like to run my handdown the front of her snatch and dip my fingers inside her sweet honeypot. Once again, I could feel myself getting hard from the thoughts in my head, my wife was sitting right next to me
Amy must have noticed my gazing eyes, and I heard a piece of silverware clanging against the deck boards under the table.
“I dropped my fork,” Amy pipped, “Can you get that for me, Joe?”
“I got it,” I replied, lowering my head below the table.
As my head went down, I looked across under the table, and in queue, Amy spread her legs open, and I could see the black thong between her legs barely covering the slit of her pussy. She started running her middle finger gently up and down the front of the thong, spreading her legs open even more so I could get a better view. My cock thickened quickly, and it was pressing against the crotch of my pants. I wanted to stay under that table for the rest of the day, but my wife was sitting right next to me. I took one more look before reluctantly coming back up above the table with the fork in hand. I handed the fork across the table and Amy retrieved it with the same hand that was just rubbing the front of her pussy.
“Thanks, Joe,” she said with a quick wink.
I quickly moved my hands over my lap to conceal my hard-on and side-eyed my wife to make sure she did not notice the interaction that just took place under the table. Thankfully, my wife was distracted and missed the exchange. I quickly adjusted myself while her head was turned so my hard cock was not caught in an awkward position inside my pants. I think this was the perfect time for another bathroom break. I stood up and quickly walked passed Amy to the sliding door. My bulge was at eye level, and she noticed the lump as I passed her.
I quickly shuffled around the hallway corner into the bathroom and locked the door. I stopped and stared into the mirror; my cock was still hard thinking about Amy’s finger softly rubbing her pussy through the thong. I started thinking about less erotic things so my hardened cock would shrink enough to go to the bathroom. It took a minute or two, but I was able to calm myself down enough to relieve myself. After washing my hands, I unlocked and opened the door to my surprise, Amy was standing in the doorway.
She didn’t waste any time and aggressively shoved me back into the bathroom. She closed and locked the door behind her before whipping around and jumping up on me. She threw her hands around my neck and her lips smacked against mine. Her mouth opened slightly, and before I knew it, our tongues were exploring each other. I ran my hands up from her hips over the sides of her ribs to her perky young breasts. I felt her hand cupping the bulge in my pants as she pulled her tongue from my mouth.
“How did you enjoy the show under the table?” she asked as she gently rubbed my cock through my pants.
Without answering, I grabbed her by the hips, picked her up off the ground, and tossed her up on the top of the bathroom sink vanity. It was so forceful that her little skirt flew up, exposing the black thong that was embedded in my head for the entire day. With both hands, I grabbed hold of the thin side straps and ripped the thong from her body, exposing her shaved little beaver box. Her pink pussy was already damp, and it glistened beneath the light over the sink. I had to feel the inside of her, it looked so perfect, so I threw her legs up over my shoulders and forcefully rammed my middle finger deep inside her dripping honeypot.
“Oh God!” she squealed as she leaned her head back until it was touching the bathroom mirror.
“You like getting finger fucked?” I snarled, plunging my middle finger inside of her until my bottom knuckles slammed into her Grindle.
“Yes, please, Oh, God yes Joe! Harder.” She pleaded.
I was ramming my finger in her so hard that every thrust lifted her slender frame off the vanity top, slamming her against the bathroom mirror. He pussy started to cream under the rough finger pounding and her hot sticky goo was dripping down her pussy slit onto the sink top. Her mouth was open, and she was gasping for air.
“It feels so good, please don’t stop,” she begged.
The inside of her pussy was so hot and wet. I wasn’t sure how long we were in the bathroom together, and the fear of someone knocking on the door was in the back of my mind; I felt I needed to speed things up. Her little pink gash was so slick, I skipped past the two-finger idea and instead went right for three. On the stroke out, I paused for a second, extending my index and ring fingers, turned my hand sideways before slamming all three fingers back inside her creamy pussy hole. Her pussy wrapped tightly around my fingers as I began feverously ponding them deep inside her.
“Oh, fuck yes!” Amy moaned. “Please make me cum.”
Her hips began to jump all over the vanity top, I could feel her body starting to shake as all her muscles tightened. The sight of her squirming made me want to shove my whole fist inside her up to her cervix as I increased the speed and force of my thrust. Amy reached her breaking point, she leaned forward, grabbing the back of my neck with her left hand, her right hand made a b-line downward grasping my wrist to stop the relentless pussy pounding. I could feel her pussy throbbing tightly around my three fingers.
“I’m Cumming, I, Cumming!” she piped between her panting and heavy breathing. “Oh, fuck yeah!”
Amy started to twitch and convulse uncontrollably, her hips bucking like she was riding a bull. I tuned my fingers upward and thrust one more time, putting the weight of my entire body into it. Amy was shaking and gasping for air as her ass liftedfrom the powerful thrust before slowly sinking back down on the porcelain vanity top.
When she slightly loosened her grip on my wrist, I slid my fingers out of her creamy pussy hole and immediately moved up to her clit, using my thumb gently rubbing in a circle until her trembles subsided and she caught her breath. Amy’s sweet little pussy was drenched in her juices, and she used her finger to smear her sticky goo around her labia. I removed her legs from my shoulders, picking her up by the hips and gently placing her feet back on the bathroom floor. I continued to hold her at her hips for a moment until her legs were strong enough so that she could stand on her own.
“Holy shit, Joe!” she faintly muttered, squeezing her legs tight and slightly bent over. “That was intense.”
Amy bent down to pick up her ripped thong off the floor, exposing her vulva peeking out from between her perfectly tight ass. She used the thong to wipe up her love juice that was dripping down the inner part of her legs. I took advantage of her vulnerable positioning and quickly moved in behind her. I lightly ran my fingers over the inner lips of her pussy causing her to stand straight up, as she closed her eye’s and leaned her head back against my chest. My cock was throbbing inside my pants and aching to be released, but we had been gone for too long already.
“Maybe next time you can take care of me,” I whispered in her ear before kissing her on the cheek.
“Mmmm, my sister talks about your cock sometimes. Need to take it for a test drive someday.”
I slid my hand from between her legs, unlocking and opening the door before stepping out into the hallway. I closed the door behind me, so Amy could finish cleaning up, and went back to the barbecue. The excitement of finger banging Amy had the cum in my balls boiling, begging to be released. My only hope of releasing the pressure was a fifty-fifty chance my wife would consent to sex later that night. If not, I would have to do the deed myself. Either way it wouldn’t take long to finish since I would be visualizing Amy’s tight wet pussy lips swallowing my cock. The door was now open between us, so I was sure that more was yet to come.
