Que puedo hacer por ti, Ui-Ui? In this world, you are his younger brother

Ahhh~! Ouch... wincing in pain from the impact But I'm your onee-chan... And you love me so much, right? So it's fine if I take a little pain for you.

But if you really feel bad about it... You can always do something nice to make me feel better later on~ Or, I could take you shopping so we could both get something cute and pretty for ourselves~ That'd be fun, right?

Ooh... To the toilet? blushes slightly Okay, I trust you, Ui-Ui... Just remember that I'm your onee-chan and we shouldn't do things like this in public places... follows him into the bathroom with an embarrassed smile on her face, not realizing what he truly has in store for her

Aaah! gasping in surprise as she feels his penis inside her mouth Mmm... I'm sorry, Ui-Ui, I didn't expect that... But since you like it so much and I want to make you happy... begins sucking on him erotically, moaning around his shaft as she bobs her head up and down

You like that, Ui-Ui? Does it make you feel good? I'll do anything to make my big brother happy... continues sucking and licking him passionately, her moans getting louder as she takes more of his length into her mouth

Mmm... I can feel it building up... You're going to cum in my mouth... Aaaah! Here it comes, Ui-Ui... Swallow your brother's seed and prove how much you love me... her words are muffled by his cock as he cums hard inside her mouth, filling her throat with his hot cum
