Mushroom Kingdom's Princess Peach showered in her castle's main restroom, glad she got saved from another one of Bowser's kidnapping/hostage schemes. However, her savior this time was not Mario, but Peachette, who was Toadette after nabbing a super crown and greatly resembled her. She kissed her as gratitude for saving her, loved it, and knew she did too. Upon finishing, she came out of the shower, dried herself with a towel and wrapped it around her body.
Peachette entered the restroom via its door in only a towel too, unaware Peach was in it. She apologized and was about to leave, but Peach told her to stay and lock the door. She did confusingly. Peach said her gratitude kiss to her made her wonder what making out with another lady was like despite having romantic feelings for Mario. Peachette said she imagined doing that with her after saving her despite feeling the same to Toad as they held hands, liking its feel, looked at each other without caring that they were virtually identical twins, lip-locked and ran their hands down one another's bodies after taking off each other's towels.
Peach lay on the floor. Peachette sat by her legs and held them up to suck her toes, then kiss them down to her pussy and finger it. Peach rubbed her breasts in joy and put her legs on the tiny bench behind Peachette, who bent forward with her head between them to give her oral and hold her breasts. Peach held her hands and panted in joy. That got louder after Peachette grabbed her ass and licked her harder. Peach held her breasts. She kissed up her stomach and sides and all over her breasts and nipples. She moved up to kiss and nibble her neck and chin. They fingered each other as Peach shut her eyes and ground her teeth in joy. She then kissed and nibbled Peachette's neck and chin.
Peachette moved up and held Peach's head to her breasts and nipples to let her kiss and suck them while spanking her and fingering her anus. She moved up more to let her kiss down her stomach and sides before sitting on her face to let her give her oral and feel her ass while holding her head. She arched back, held Peach's sides, faced the ceiling, shut her eyes, and yelled in joy at a point. Peach fingered her vagina, kissed down her legs and thighs to her feet and sucked her toes. She about faced. Peach kissed and licked her butt cheeks as they fondled Peach's pussy, sometimes one at a time and others together. They pinched each other's breasts. Peachette bounced in joy. Peach licked between her ass cheeks and sucked her anus.
