I’ve been dating Kylie for about a year now and I’m so lucky to have her, she’s a 4’11” petite blonde with curly hair that stops at her shoulders. She has such a sweet and friendly personality, and was wearing a frilly white sundress this summer’s afternoon. I run track in school so I’m 5’2” with a sleek somewhat muscular physique, and hazel colored hair with a good tan from running outside.
We went from my back porch into the kitchen to grab the our drinks before watching TV in the living room. Both of my parents work so we hade the house almost to ourselves this afternoon. But there was one other person there…
“Ohhhh what’ cha watching?” We both turned our heads to my sister Elli at the top of the stairs. Elli was going into her senior year at our next school and she was drop dead gorgeous. She was about the same height as me with similar hair and skin color, but from laying out in the sun instead of running. She mostly lifted weights for exercise so she still had a sleek toned figure with a nice firm round ass. Above all that though were her massive DD sized breasts that all the boys at school, and even the teachers, can’t help but take glances at.
But that’s not by accident, she loves the attention and is always dressing for it. She’ll either were tight leggings that show how tight her ass is, a skirt that really shows for thighs and sometimes panties while bending over, and even shorts that would be better described as belts. Her shirts would be a thin material to see her bra, or tank top that show cased her golden cleavage, or a tight blouse with the buttons threating to fly off. Over this past year she’s been particularly bad, not just in how she dresses, but also how she acts when our parents are gone. When I’m watching TV, she’ll come in the living to “stretch” before going on a jog, wearing these skintight shorts and sports bra, and bending over or sticking her tits right at me. When I’m eating, she usually leans on the table or counter while talking to me to ensure I get a great view of her cleavage. I can’t help but get rosy cheeks or stop my dick from getting hard, to which she always giggles while pretending not to notice.
This time she must’ve just been getting out of bed as her hair was done up in a bun and she was wearing this white silky robe that gave ample cleavage and came down to the middle of her thighs. “Are you just waking up?” I asked unable to keep my eyes off her. “Hmph” she smirked “it’s summer so I’ll sleep as long as I want, got a problem with that bro?” she asked while bending over the rail, showing off those luscious tits even more. I could feel drool piling up in my mouth and I had a hard time answering her “I… I guess not.. do what you want to” I said. She smiled and her eyes narrowed, “sounds good, I think I’ll finish getting ready and come watch with you two” she responded. I was going to say something back but instead of her standing up she turned and stuck her ass out at the rail, so me and Kylie could see the bottom of her ass and what looked like a thong. I couldn’t say anything for a few seconds after that, but after a little bit of time we heard the shower cut on and I turned to Kylie.
“she’s not going to leave us alone, let’s go to your place instead” I pleaded. Kylie was looking straight at the TV and said “Uggh but its so hot out, plus I really like this show. Let’s just stay here until it gets cooler out”. She said while turning towards me to smile and give a kiss on the cheeks. She looked so innocent and pretty, I couldn’t say no to a face like that and I begrudgingly relented.

We continued to sip our drinks and watch TV for about 30 min before my sister made her return. “Oh I love this show” she said to alert us of her presence. This time she had snuck halfway down the stairs before saying something, and I couldn’t help but be stunned by what she was wearing. She had on cut off jeans that were so short her ass cheeks were coming out the bottom and her legs were still glistening from her shower. Her top was a loose fitting mid-cut off tank top, when she got down the stairs and faced us my eyes went from her smooth and petite stomach before moving up to her enormous cleavage that had her nipples poking though, so we knew she wasn’t wearing a bra.
She walked over and sat in a chair to our side, “man it sure is hot out today” she said while grabbing a magazine off the table to fan herself. “You guys had the right idea staying in” she continued with an evil smile on her face, you could notice she put on some make-up like mascara and pale lip gloss. She was sitting up right poking out her chest and had crossed her legs to give me a full view of her thigh.
We tried to keep watching the show, one of those generic zit coms, but it was nearly impossible for me to keep focus on it with such a bombshell of a distraction a few feet from me. She would make comments about the show or try to make small talk with Kylie just to get my attention back. All the while doing so twirling her hazel brown hair, shifting her legs, and adjusting the straps on her top that usually still left them on the edge of her shoulders. I absolutely could NOT let Kylie see me checking out my own sister, but I couldn’t resist taking glances at her.
At one point she laughed a little louder and those straps fell off, keeping her top just barely above her nipples. My eyes lingered on this sight and Ellie turned and caught me, she licked her lips and gave a wink, “funny show uh?” she asked in a knowing tone. In a panic wondering if Kylie just saw that “Um uhh yeah, it sure is” I stammered. Ellie having not fixed her top hums “yeah… it is” with a big grin on her face. Suddenly, we hear something falling on the ground behind her, “Oops… my phone, don’t want to lose that” she said before standing up.
Ellie turned having her feet apart and keeping her legs straight, bent over to reach behind the chair to grab her phone. Her shorts already barely covered her ass, and now they were stretched out, further revealing her cheeks. Even more than that tough, the fabric between her legs was so small we could see her baby blue thong behind them. My eyes were glued onto my sisters finely toned backside as she struggled to grab her phone, that was until I heard my girlfriend beside me gasp and realized that I was in a dangerous spot.
I quickly stood up, “You know what it’s way too nice to stay inside” I said while tugging Kylie onto her feet, “we need to enjoy this while we can, come on Kylie” I continued while grabbing our drinks and hurrying outside. I knew the only way to get out of this situation was to literally leave it as soon as possible. After getting outside I looked up at the clear blue sky and said “See, it’s too beautiful out to spend the day in a stuffy room, don’t you agree Kylie” I asked while turning to give her back her drink. However, Kylie was in fact not behind me, “Kylie…?” I asked puzzlingly as if she was there. I slowly walked back into the house and to the room where I last saw her, and when entering the room, my jaw dropped to the floor.

Kylie was still there and facing me, but I know she wasn’t looking at me because her eyes were nearly rolled into the back of her head. Ellie’s head was right next to hers and had a hand covering Kylie’s mouth, she stared me down with a nasty grin on her face. I was so confused on what was wrong with Kylie until I looked down and saw the fabric of Kylie’s skirt shaking vigorously right around her private area and her legs her wobbling.
“My lil bro Zack hasn’t been taking good care of you, has he?” Ellie asked Kylie. Kylie closed her eyes and moaned into my sister’s hand, and after staring blankly for a second, I finally found my voice. “Wha… What are you doing?” I meekly asked Kylie, or Ellie, I wasn’t sure who I should be questioning.
“Zach you’re such a poor dumb boyfriend, you didn’t even notice Kylie checking me out earlier” Ellie said. “What!?” I said shocked and confused while realizing all that time she was flaunting her gorgeous body, she wasn’t trying to get under my skin, but under my girlfriend’s skirt.
“That’s right…” Ellie said “… and I can tell you haven’t been taking care of her needs, she’s already so wet”. Ellie released Kylie’s mouth and I heard her start moaning, she always seemed so innocent, I never thought she would be into something like this. Ellie took her cheek and pulled into a deep passionate kiss, once they separated, she asked “you want me don’t you Kylie?”
“Yes yes… oh my god yes… you’re so hot… I’ve wanted you for so long!” Kylie replied between breaths of making out with Ellie before finally locking their lips together and playing with the other’s tongue. I was in a trance watching these two beautiful girls working each other’s mouths and dick was now at full attention. Instinctively I started to take a couple steps forward…

“Ah ah ah you stay right there Zack…” Ellie said “… you’ve been such a bad boyfriend, you need to watch and learn a little first”. She pulled the straps of Kylie’s sundress off her shoulders and pulled it to the floor. I’ve seen her in swimsuits before, but now seeing her in this cute white panty and bra combo was another thing altogether. “Has he ever seen you naked Kylie?” Ellie asked her. “No… we never tried anything past kissing she replied with a smirk on her face. “Oohhh this is going to be so much fun!” Ellie exclaimed while snapping off Kylie’s bra. It was my first time seeing her tits and they were amazing, she had tiny nipples that resided over bumps of flesh that were just about a handful size.
The two began to make out again, this time caressing each other’s breasts and grabbing their asses as well. At this point I was rubbing myself through my pants and making deep moaning sounds as I watched the two go to work on each other. “I think we need this to come off now” Kylie said with a grin, she grabbed the hem of Ellie’s shirt and pulled it up over her head. Ellie’s huge glorious tits were finally on full display for me, each breast was the size of a melon that jutted out from her thin frame, her nipples were a dark pick color and the size of half dollar coins.
Kylie immediately took one nipple in her mouth while grabbing the other, me and Ellie deeply moaned at the same time. “Hmmmm… well lil bro, what are you waiting for?” Ellie said while calling me with her finger. I rushed over and knelt next to my girlfriend and sucked on Ellie’s other tit, she had been teasing me with these globes for years now and I was finally getting my chance to act on them.
I used one hand hold her tit while the other was groping my sister’s ass, running my hand up and down her leg while my tongue swirled her nipple. I could feel Kylie doing the same next to me, I stopped briefly to tell her “Kylie this is craz…” but she grabbed my chin and brought me in for a deep passionate kiss. We broke apart and she said “just shut up and kiss your sister” then pushed me onto my feet. Giggling, Ellie said “you heard her” before wrapping her arms around my head and locking her lips with mine. Her lips were so soft, and her tongue masterfully caressed my own, my hand moved from her ass to the back of her head to press into this as much as possible.

While I was making out with my sister, Kylie was undoing my belt and dragged my pants down, my cock sprang forward, and Kylie immediately engulfed it. I moaned into my sister’s mouth as my girlfriend sucked my rock-hard dick. Ellie pulled away to take my shirt off, “Wow, my brother as such a nice body” she said while running her hands on my abs and pecs.
“Not as nice yours” I said back while groping her huge tits again. “Well just wait until you see the rest of it” she responded while tugging the waistline of her shorts and swinging her hips side to side. She slid her jeans down while turning to give an amazing view of her ass while she was bent over. Kylie had paused sucking my dick and was instead jacking me off so she could see as well. Ellie’s tight and toned ass were almost completely exposed to us, those bronze globes shined before mine and Kylie’s eyes. Ellie stayed bent over and put her hands on the chair, “Well Zack, would you like to do the honors?” Ellie asked.
“Hell yeah” I exclaimed and grabbed the straps of her baby blue thong and pulled it down to the floor, now not just her ass, but her pussy was on display. She slowly stood back up and turned around, her naked body was easily the most beautiful and sexy thing I had ever seen. Kylie and I both moaned at the sight before Ellie gave her commands.
“Kylie, I want you to stand up but leave your panties on the floor” she said. Kylie nodded and stood up while slipping her remaining garments off. The only thing that could have taken my eyes off my sister was my girlfriend, whom I had spent the past year with I was now seeing her completely naked. Her ass wasn’t as big as Ellie’s but was still a decent size and well-toned, her pussy was so nice and sleek that my hands immediately began to rub her front and back side. “Kylie babe, you have an amazing body” I told her, she smiled, and her cheeks seemed to get a little more red.
“Hmm that’s what I like to see lil bro…” Ellie said, “… now get on the floor”. I obeyed her and laid on my back, my dick pointing straight at the ceiling. Ellie continued “Kylie, you’re going to fuck my brother and lose both of your virginities. I’m going to sit on his face so he can eat me out while I watch” she finished.
Kylie’s eyes narrowed and she growled “yeah let’s do him” and slowly kneeled putting her pussy right over my dick. Ellie did the same but over my face, I noticed that her pussy was glistening from how wet she was. Kylie slid herself onto my essence and exclaimed as she did, I gasped while running my tongue on Ellie’s.
My moans were muffled while the girls were at a large volume. The pace for us began to quicken with Kylie bouncing up and down my cock as fast as she could. I moved my tongue hastily trying to taste my sister as much as possible. There started to be breaks between them, which told me that they were making out while fucking me. The image of them doing so formed in my head and got me even more turned on.
All of this started to really swell up with in me, and I wasn’t the only one feeling this. Kylie began to have pauses on her down swing shaking, and I felt Ellie’s pussy produce even more juices. I was on the cusp of cumming and my big sister knew it. Kylie with her loudest moan stopped my dick fully in her and shaking, Ellie say her orgasm and commanded “Kylie quick get back”, and Kylie managed to roll herself onto her back and off my cock. Ellie then came down and swallowed me up, wrapping her tongue around my dick, tasting my pre-cum and Kylie’s pussy juices. I was now in a 69 with my hot sister and we had both reached our limits. We shook and moaned while pouring our remaining essence into the others mouth, both of us swallowing as much as we could.
Ellie slowly rolled herself off me, leaving all three of us gasping for air and sweating at the exertion we gave. Finally, Kylie said “Wow… this summer just got a lot more interesting” with a giggle. “Yeah…” said Ellie “… so did living in this house” she finished looking at me with smokey eyes. I looked from her to my girlfriend who was giving the same look, then to the ceiling and laughed “Oh god… fuck me”.
