After that unforgettable first night with Emma, everything between us changed in the most beautiful and addictive way.
For the next two weeks, while our parents were still away at the lake house, Emma and I couldn’t keep our hands off each other. We had sex every single day - sometimes slow and romantic, sometimes rough and desperate. We fucked in the shower, on the kitchen counter, in the backyard at midnight under the stars, and even once in our parents’ bed when we felt extra naughty.
Emma became my teacher and my lover. She taught me how to eat pussy properly, how to use my fingers to make her squirt, and how to scissor until both of us were shaking and screaming. I had never felt so desired, so wanted, and so completely satisfied in my life.
But deep down, both of us wanted more.
One lazy afternoon, while we were lying naked in bed after another intense session, Emma turned to me with a mischievous smile.
“Liv… I’ve been thinking,” she said, tracing circles on my bare breast with her finger. “We both love what we’re doing… but don’t you ever wonder what it would feel like to have a guy join us?”
I felt a rush of nervousness and excitement at the same time. “You mean… a threesome?”
She nodded, biting her lip. “Yeah. But it has to be someone we trust completely. Someone who won’t tell anyone and won’t make things weird.”
We both fell silent for a moment, thinking. Then Emma’s eyes lit up.
“What about Tyler?” she asked.
Tyler was our cousin - my dad’s brother’s son. He was 24, tall, athletic, with messy dark hair and a charming smile. He lived in Portland but was coming to stay with us for two weeks because his parents were going on a cruise. He had always been close to both of us, almost like a big brother, but lately I had noticed him checking us out when he thought we weren’t looking.
“You think he would actually do it?” I asked, my pussy already tingling at the thought.
Emma grinned. “Only one way to find out. We seduce him. Slowly. Safely. And if he’s into it… we make it happen.”
Tyler arrived three days later.
He looked even better than I remembered - tanned from working outdoors, broad shoulders, and that easy, confident smile. When he hugged me, I made sure to press my body against him a little longer than necessary. When he hugged Emma, she did the same, wearing a tiny white crop top with no bra.
The first few days we played it cool. We swam in the pool together, watched movies at night, and teased him playfully. Emma and I would “accidentally” wear very revealing outfits around the house — short shorts, tight tank tops, bikinis by the pool. We made sure Tyler got plenty of views of our bodies.
One evening, after our parents had gone to bed early, the three of us were in the living room watching a movie. Emma and I were on the big sectional couch, Tyler sitting between us. I was wearing a loose tank top and tiny cotton shorts with no panties. Emma was in an oversized T-shirt that barely covered her ass.
Halfway through the movie, Emma stretched dramatically, her shirt riding up and flashing her bare pussy for a split second. Tyler’s eyes widened, but he tried to play it cool.
Emma noticed and smirked. She leaned over and whispered something in my ear. I smiled and nodded.
I casually placed my hand on Tyler’s thigh, slowly sliding it higher. He tensed but didn’t move away. Emma did the same on his other side.
“Tyler…” Emma said softly, her voice sweet and seductive. “We’ve been talking… and we both think you’re really hot.”
He looked stunned. “Wait… what?”
I leaned closer, my breast pressing against his arm. “We want to play with you. All three of us. Together.”
His breathing got heavier. “You’re serious?”
“Very serious,” Emma said, sliding her hand all the way up to his crotch. She gently squeezed the growing bulge in his shorts. “We’ve already been playing with each other for weeks. Now we want a guy we trust… and we both want you.”
Tyler looked back and forth between us, completely shocked but clearly turned on. “Holy shit… you two have been… together?”
I nodded and kissed Emma softly on the lips right in front of him. We made it slow and sensual, tongues dancing, moaning quietly into each other’s mouths. When we pulled apart, Tyler’s cock was visibly straining against his shorts.
Emma reached over and pulled his shorts down. His cock sprang free - thick, long, and already leaking precum.
“Wow…” I whispered.
Emma stroked him slowly while looking into his eyes. “You can say no and we’ll never mention it again. But if you say yes… you get to fuck both of us. Anytime we want. As long as you keep it secret.”
Tyler swallowed hard, then nodded. “Fuck yes.”
That was all we needed.
Emma leaned down first and took him into her mouth. She sucked him slowly and deeply, making wet, sloppy sounds while I kissed his neck and chest. Tyler groaned loudly, his hand gently resting on Emma’s head.
I couldn’t wait any longer. I moved down and joined my sister. We took turns sucking his cock - sometimes both of us licking the shaft at the same time, our tongues touching, kissing each other with his cock between our lips. Tyler looked like he was in heaven.
After a few minutes, Emma climbed on top of him in reverse cowgirl. She sank down onto his thick cock with a long moan.
“Oh my god… he’s so thick,” she gasped.
She started riding him slowly, her perfect ass bouncing. I straddled Tyler’s face, facing Emma, so he could eat my pussy while she rode him. The three of us moved together in perfect rhythm - Emma bouncing on his cock, me grinding on his tongue, and both of us kissing each other passionately.
It was the hottest thing I had ever experienced.
We switched positions multiple times. Tyler fucked Emma doggy style while she ate my pussy. Then he fucked me missionary while Emma sat on my face. We tried double blowjob again, both of us on our knees worshipping his cock until he couldn’t hold back anymore.
When he finally came, Emma and I were kneeling side by side with our tongues out. He exploded across both our faces and tongues, thick ropes of cum landing on our lips, cheeks, and breasts. We kissed each other deeply, sharing his cum, licking it off each other’s faces while Tyler watched in awe.
That was only the first night.
For the rest of Tyler’s two-week stay, the three of us fucked constantly. We had threesomes in the pool at midnight, in the living room while our parents were asleep upstairs, and even once in the backyard under the stars.
Emma and I loved tag-teaming him - one of us riding his cock while the other sat on his face. We loved making him watch us fuck each other first, then inviting him to join. Tyler turned out to be surprisingly dominant in bed, taking control and fucking us both hard and deep.
By the end of the vacation, the three of us had become completely addicted to each other.
But we knew we had to be extremely careful.
Our parents had no idea what was happening under their roof.
And that danger only made everything even hotter.
