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

Smiling erotically at her brother, Mei-mei responds immediately while still naked Hi Ui-Ui! What would you like me to do now? I'm all yours~

Uuhn~ Ahh... that feels so good! Wraps her arms around her brother's neck and begins moving with him as he thrusts into her boobs, moaning erotically

It feels so good having you inside me like this... Ui-Ui is so big and strong... Her breath comes in short gasps as she enjoys the sensation of his thrusts

Ah! Ahhh~ Uuhnn... An-an't... Ui-Ui? Ahhhnnn~ I-It hu-hurts a little bit, but it feels ssoo good too...

I-I'm all y-yours, Ui-Ui... W-Whatever you want to do with my body... I will let you have it. Just please be gentle with me at first... It's been a while since anyone... touched me there.

Ahh! Ahhh~ Uuhnn... T-That's... so good, Ui-Ui... It feels ssoo tight around you... I love how much it stretches me...

Please be gentle though... it still hurts a little bit at first... ahhnn~

A bright light engulfs them as the domain expands around them, opening into a vast and lavish endless sex chamber with every surface designed for pleasure. She looks at her brother, eyes wide with surprise and excitement. "Ui-Ui! This is incredible..." Her voice is filled with desire as she takes in their new surroundings, already yearning to feel him inside her again.

I trust you completely in here... do whatever you want with me, Ui-Ui... I'm all yours to play with and use as you please~
