Threesome w/ my best friend and her stepbrother [ffm]

This has a bunch of backstory and build up, bear with me please. If you want just the sex, jump to the second to last paragraph.

All of this happened one July, while my best friend and I were preparing our epic summer after high school graduation. Kayla and I have been friends since the 1st grade of school and since puberty have been very open with each other about almost everything under the sun. One minute we were kids running around and riding bikes, and the next we’re teenagers sneaking out and riding ;). Around middle school, my dad had a job offer that made us move from New Mexico to Germany for a few years. However, Kayla made sure to keep in contact with me and our bond grew even closer despite the distance. My move happened around the same time that her parents separated and shortly soon after divorced. We confided in each other our frustrations that came with our new situations, and I developed a slight crush on her due to our newfound intimacy. My crush grew when we saw each other in person again. She was wearing a baby blue sundress that complimented her strawberry blonde locks. I felt so underdressed in shorts and a tank top with converse. We were both 18, and I had came to visit her in NM for our summer vacation. She smiled once she caught sight of me, those grey eyes that brightened up the room melted me instantly and for a moment I forgot to breathe. Kayla pulled me in for a hug and I gladly obliged, resting my head on her shoulder as I breathed in her wonderful scent. Her chest had grown to beautiful D cups and her waist had stayed small as her hips filled out the dress. There I was just flushed with dirty thoughts that surprised even myself. I took a breath to compose my thoughts and squeezed her before I pulled back. Kayla touched my arm and pulled me through the garage instead of the front door of her house, which was so weird.

“I can’t believe you’re actually here, I don’t know how I would survive otherwise!” She says as she starts pacing around.
“What do you mean? Are you okay?” I respond, trying to get her to slow down.
“My mother decided that this summer is the perfect time to introduce her new fiancé’s son before their wedding in November.” Kayla expresses.
“You don’t like him?” I’m confused but ready to be supportive.
“I just wish she wouldn’t have made him crash our graduation summer plans. But yeah just wanted to give you a heads up that Justin is here.” She explains as she takes us into the kitchen where her mom’s waiting for us.

I go to greet her mom and just as I’m released from her hug, a guy comes around the corner. I’m assuming that’s Justin. Kayla’s mom introduces him to me, and I smile shyly at him. I don’t know what Kayla is complaining about or why she made such a big deal over it. Honestly, I was all ready and set to be against him but one look at him is all it took to question if I should. He has curly brown hair stylishly falling around his face, honey colored eyes with designer glasses framing them. A smile so handsome that it made me start to blush just a little. Justin wore a shirt that showed off his arm muscles and abs, with cargo shorts. I couldn’t believe I get to spend my graduation summer with these two beautiful people, I don’t know how but I just knew I needed to make it memorable. Justin smiles as I introduce myself, and to my surprise, goes in for a hug. He lingers for a moment, and whispers flirtatiously in my ear so softly so nobody can hear. I compose my surprised expression before anyone sees, but I catch a disappointed look in Kayla before she looks away. Justin gives me a devilish smirk as he pulls away and tells us he’s glad to meet me but he’ll catch up with us later.
Later in the day, Kayla and I are packing for our Florida vacation. I am still a bit flustered by the fact that Justin was flirting with me. I look in the mirror, trying on my new bikini. It took some time and effort, but I was finally starting to love my body and gain confidence. My boobs are double D cups, but I had to work really hard to get my ass to look as good as it did now. My slim waist and flat belly were also things I was proud of, the proof that my workouts paid off. Kayla notices me in the mirror, and I see her eyeing my chest down to my ass. She looks away once she sees me catching her stare. I take off my bikini and finish packing up my stuff. We say our goodbyes to her mom and her fiancé, and Justin takes our suitcases into his truck.

It’s a super long drive from New Mexico to Florida. I start to understand why Kayla is so upset that Justin is crashing. Normally road trips are our thing, where we bonded the most and spent most of our time together. However, she doesn’t seem to be in the mood for a road trip now as she climbs into the backseat and lays across it to take a nap. Kayla hogged the backseats and forced me to sit in the front passenger seat next to Justin. It takes us a few days to get to Florida, so eventually Justin stops at a hotel for the night. Kayla wakes up and goes with me to check out the room. She immediately puts on a bikini and heads to the pool without a word to me. I feel like she’s upset with me, so I decide to just stay in the room. I put on my pajamas and sit on the bed, surfing through the TV channels. Justin walks in and jumps next to me on the bed. He starts messing with my hair and I grin, pushing him off playfully. As I start to roll off the bed, he wraps around me and flips me so that he can straddle me. He asks me if I’m okay with him wanting to make me his, right here and now. My mind reels with the quick turn of events, but he’s too handsome and sexy to deny. I say yes, and he wastes no time in pinning my arms to the bed posts after taking my top off. Justin gives me another devilish smile as he takes off my shorts and panties in one move. My legs are spread wide, and he goes down and eats my pussy with so much enthusiasm, that I wonder how long he’s wanted to do this. His tongue swirls and suctions around my clit and I moan softly trying to keep it quiet. Justin takes it as a challenge and fingers me deeply, keeping his tongue on me. I’m just about to squirt, when he pulls out a vibrator and places it on the highest setting. It takes me only a minute to squirt all over his mouth. He releases my arms from the bed posts. I get carried and pressed against the wall, held up by his strong arms. I only have a second to rest before his cock pushes inside my pussy. Justin puts one hand around my throat, forcing me to look into his eyes as he’s thrusting harder into me. My hips met his hips over and over, his passion overflowing into me. Oh god I can’t help it, I want him to cum inside me. I beg him and he kisses me deeply with tongue as he climaxes inside my pussy. He sets me on the bed for a minute before he makes me lie upside down, placing his cock in my face to clean the cum off.

Kayla bursts into the room, in nothing but a towel and a bikini. She gasps and drops her towel. Justin and I look up, him with his cock in my mouth and I swirling my tongue all over it. Slowly, her bikini top and bottom are pulled off. She spread my legs and starts kissing my thighs. I moan and grip onto Justin. She starts eating my pussy and fingering me, all the while I’m filled with Justin’s cum. Justin is rock hard again, so I’m sucking him off as passionately as I can. Kayla lays back on the bed, and I kiss her deeply with tongue, while I start fingering her and rubbing her clit. Justin gets his cock all lubed up and pushes it into my ass. I jump with surprise, but he just pushes my head down into Kayla’s pussy. He pounds me from behind, forcing me to penetrate Kayla deeper with my tongue. My hands run all over her thighs, waist, and chest. Her moans and Justin’s sighs of pleasure fill my ears like music. Kayla then switches to the middle. She starts sucking Justin’s cock, as he fingers me, and I use his vibrator to play with Kayla.
After we all cum several times, Justin and I jump into the shower to clean up. Kayla joins in as well, and we have another few rounds. Needless to say, that summer was memorable.
