Solange's choice of tonalities in her undergarments is not a simple coincidence, it is her way of expressing to Khallyon that he possesses her completely.
"Look at you, What a Naughty, Naughty Aunty"; Khallyon's comment makes the Old Damsel to moan, she adores to hear him calling her Aunty, the rest of the phrase content, is irrelevant for her.
Right at that moment, the Rogue Cadet moves swiftly and fastly his left hand, taking away Solange's breath as he grasps roughly the fragile and slender neck of the Old Damsel that will become truly a Woman when he clims her, making her, "His Woman".
"Naughty, Naughty Aunty…"; Say Khallyon with a low and slow intonation, lifting his Aunt's chin with his index finger as he moves his thumb to hover above the puffy kissable lips the Damsel has on her flushed and exited mature face.
Tentation takes a hold on Solange, extending his lips to try and give a short peck to the Rogue Cadet's thumb.
