Be careful, it's not just a kiss, she's draining your energy! It'll be bad if you don't escape!" Mona screamed to her.
("Even if you said so... my head is going.... blank... I can't feel... My strength...") thought Noir.
"Mmmmhhhh... Good, you don't need to think. Just drink my saliva some more....❤" whispered the succubus.
"Mmmhh... nghhh.... Anhhhh.......... Gulp... Gulp....nnnhhhhh" Noir completely succumbed to her overwhelmingly deep first kiss.
("My first kiss..... To be with a woman...... I should not.... This is... Wrong... But why are her lips so warm and... Moist and.... Feels good....... My body feels really hot....... Mona..... help me....")
"Aha... You naughty little princess.. Don't be afraid... Just lay it bare, and surrender to the pleasure.... Your delicious energy... Is all mine❤" the succubus continued to whisper thru the intense kiss.

Extra scene where Noir failed to summon her persona, and got teased by a shadow succubus. (Dunno what shadow would do with Haru. Guess more succubus won't do any harm).
