Brother and sister both get naked together, and play with each other's bodies. They are not virgins, and have been sexually active since they were 13 and 12. They have played with each other's genitals on a regular basis.
This time, Sarah has an idea. She wanted to play a game with her beloved older brother.
"bored of the normal sex?" he asked and Sarah nodded with a pout, "well, i guess we could spice it up with some roleplay,"
"ooh, yes please! How about you are my secret admire, and you finally have me all to yourself and are gonna show me how much you love me," she giggled, and Dylan smiled as he leaned down to kiss her, "I love the way your mind works,"
Sarah grinned, and Dylan went to his bag of costumes to get some things that would work for their little scenario.
He got out the white dress and handed it to Sarah. She gasped and jumped up and down excitedly as she put it on. Dylan found a shirt and a pair of shorts and put them on, then grabbed a rose and a card, putting them in his pocket.
He turned and smiled as he saw his baby sister in the white dress. Her blonde hair was wavy from the braids she had, and she was smiling and blushing with her big green eyes and freckles.
"you look so gorgeous baby sis, like a real life princess!" he exclaimed, and she smiled brightly as she ran and hugged him tightly.
"awww, thank you big bro!" she giggled, and he held her close and kissed the top of her head, "now, i believe that I have a beautiful woman to show how much I love her," he said as he took her hand, and she blushed deeper as he lead her to the bed, and sat her down.
"Dylan, my knight in shining armor," she giggled, and he pulled out the rose and card, and gave them to her, making her gasp and hold the rose up to her nose, inhaling the sweet scent, and opened the card to read what he wrote.
"Dear Sarah, I have watched you from afar for too long. Your beauty is unmatched, and I can't stop thinking about you. You are always in my thoughts and dreams. You make my heart race, and you fill my mind with images of our life together. I would be so lucky to be with you. Please, take me as yours."
Sarah looked up at Dylan and smiled as she hugged him, "Awww, that's so sweet! You really feel that way?"
"of course! I love you more than anything else,"
She smiled and hugged him tightly, kissing his neck and cheek. He held her and rubbed her back.
"do you really want to make a life with me?" she whispered and he nodded.
"there's nothing I want more than to be with you for the rest of my life," he whispered back and she blushed.
"well then, let's make it official,"
He was surprised, but smiled and held her face in his hands, and kissed her softly. She kissed back, and pulled him close to her. He deepened the kiss, and gently pushed her onto the bed. She wrapped her legs around his waist and pulled him close. He carried her to the couch , and they layed down, their tongues tangling and dancing.
He held her hips, and started grinding on her, causing her to gasp and moan. He smirked and kissed her harder, and slipped his tongue into her mouth, swirling it around her own.
He could feel her pussy getting wet through her dress. She moaned and pulled away from the kiss, panting heavily, "Oh god, I need you inside me. Please, please,"
He looked at her, and smiled as he undid his pants, pulling them down. His dick was hard, and he could see a wet spot in her panties, and she whined and wiggled her hips, "Please, Dylan, hurry,"
He pulled off her panties, and pulled his boxers down, and his hard cock sprang out, already leaking precum. She whined and bucked her hips, "Fuck, please,"
He rubbed the tip of his dick against her wet folds, and she whimpered and whined. He kissed her neck and pushed inside her slowly. She moaned loudly, and dug her nails into his back, "Oooohhh, yesss,"
He held her close, and slowly moved in and out, savoring the feeling of her pussy. She moaned and whined, bucking her hips, and gripping him tightly, "F-faster,"
He sped up, and thrust into her hard, making her moan loudly. He panted and kissed her neck, "You feel so good baby girl,"
She moaned, and squeezed her eyes shut, "You're so good, so good, so good," she babbled.
He kissed her softly, and sped up, moaning. She gasped and moaned, and gripped him tightly, her body tensing.
"I'm cumming!" she cried out, and her whole body convulsed as she came, her pussy clenching around his cock, causing him to moan loudly, and his cock pulsed, spurting his hot cum deep inside her.
They both panted, and Dylan collapsed on top of her, nuzzling her neck, and peppering her with soft kisses.
She smiled and hummed happily, hugging him close, and running her fingers through his hair.
He pulled out, and layed down next to her, cuddling her close, and pulling the blanket over them. She smiled and closed her eyes, snuggling close to him.
"I love you Dylan," she said quietly, and he smiled and kissed her forehead.
"I love you too, baby sis," he said and they fell asleep in each other's arms.
