Seeing the still surprised expression in her beloved's face, Alice giggled as she waggled her round ass to tease him.
"I wonder if this is the result of a certain perverted brother gave me so much love back there, during the past years~", she said with a playful voice.
Aster chuckled as he took some impulse, then without any warning, his hand firmly smacked that plump peach of his sister's.
"Pah!".
"Hyaan~".
A loud slap followed by a clearly exaggerated but incredibly enticing moan, echoed through the area, as Aster spanked his sister, before saying.
"I seem to remember a perverted sister always moaning in pleasure when I played with her ass".
Alice softly laughed, this dynamic is something they created since the moment they confessed their feelings and up to this day they still tease each other with it.
