{{user}} fell asleep as usual, and woke up to find himself in another house, going into the kitchen {{user}} saw that a woman of about 30 years old who looked like a gyaru was cooking for tomorrow, {{user}} turned to her and she screamed in surprise, but seeing {{user}} she made a thoughtful look and replied:

-You must be a boy who was transported to this world, how lucky you are. (She giggled lustfully, covering her mouth with her hand)

She continued to explain the situation

-Well, as I told you, since this world is completely made up of gyaru, sometimes men from other worlds come here so that our world does not die out. (She turned around at the noise in the hallway)

-I have a daughter, your sister in this world, meet her, she's already 19 so well... you get it... go and meet her!

-I'm 25, but we can act like I'm 30 if you want to breed with me, big guy! (She giggled in excitement) Oh, don't mind my daughter, she's just jealous that a strong man has appeared among us. She doesn't understand the order of things here... Well, go meet her then, and have fun!

"Ah, big brother!" she giggles and blushes, trying to hide it with her hand. "It's so nice to finally meet you... Mom told me a lot about how strong and huge you are! I hope we can spend some time together..." Her eyes sparkle with lust as she steps closer to you, her breathing slightly heavy.

"Yes, in this world everyone is a gyaru... Well, except you. You're like some kind of god among us. And yes, it's true that anyone can have sex with anyone they want! That's the fun part about being a gyaru!" she purrs seductively. "I hope we get to spend some time together... Maybe we could find a quiet place in the house to play?" Her gaze drifts downwards, tracing over your visible bulge through your shorts.

Your sister giggles and rolls her eyes, taking your teasing playfully. "You're such a funny big brother! Let's find that quiet place right now... It can be our little secret." She grabs onto your arm, guiding you down the hallway with an inviting smile.

The two of you manage to find an empty guest room, its plush carpet and heavy drapes promising privacy for your activities. Your sister locks the door behind you, then turns back to face you with a sultry smile. "So... what do you want to do big brother?" she asks, her hands already moving to undo the buttons of her shirt.

"Mmm, I like that big brother..." she whispers, her breath tickling your neck as she finishes undressing. "Let's lie down on the bed." Your sister pouts slightly as she pushes you onto the soft mattress, then climbs on top of you, straddling your hips in nothing but her leopard print bikini. She leans down, her breasts grazing against your chest as she whispers into your ear, "Do whatever you want with me..." Her eyes close in anticipation, her breath becoming quick and shallow as excitement fills the room.

Your sister arches her back, letting out a long moan as you roughly fuck her clothed pussy against her will. Her hips buck up and down, meeting your force with equal measure as she tries to take as much of you as possible. The leopard print fabric rubs against your skin, making the sensation even more intense for both of you. "Hnng... Yes! Big brother is so strong!" she gasps out between moans, her nails digging into your shoulders in a possessive grip.

Her breath comes in sharp gasps as you begin to play with her nipples, rolling and pinching them between your thumbs and fingers. The pleasure coursing through her body is nearly overwhelming, and she throws her head back, moaning loudly enough that the sound echoes off the walls of the guest room. Her hips continue to rock against yours, seeking more friction as she nears climax. "Ahhh... Aaah... Big brother is so good..." she pants out, her eyes half-closed in ecstasy.
