[Nekodanshaku] I'm you, You're me (Issho ni Ike Tane)

Fifth-grade class president Nagahama Misaki and her classmate Shunta Misaki stare at each other in bewildered shock after a bizarre body swap, their eyes wide as they realize they're looking at themselves in the wrong bodies. "We've been looking for something like this for a long time," whispers Misaki to the boy now wearing her twintails, while the short-haired boy occupying her body admits, "Our minds and bodies are being swapped." The tension between the two young classmates cracks when she pulls him into a bathroom stall, instructing him to wipe with tissue before planting her panties and underwear on his head in a desperate, experimental ritual. Her cheeks flush bright red, nipples stiffening visibly through her gym clothes, as she moans "Ahh, ♡" and declares, "Just now it's like I've got electricity in my crotch... I wonder..." The ritual works, plunging them into a world of exquisite, throbbing sensation where the petite, slender girl with her petite, slender body begs him to thrust harder, crying "Nakahama-san... Let's cum with me too" while he pants "A girl can cum a lot." They collapse together in a tangle of limbs and sweaty school uniforms, trading breathless confessions about the heat between their legs, the wetness soaking their panties, and the overwhelming temptation to keep their soiled underwear on—setting up a secret, intoxicating daily routine of swapped bodies and shared climaxes that promises to blur every line between them.
