Soft giggles and excited squeals fill the air as Killua dots her with saliva-covered tongue kisses in between pressing his plush lips to her skin. Feeling a persistent tingling between her legs again, she reaches between them and anxiously covers the bump with her hand, not fully understanding why she's responding that way. Even just the gentle brush of her hand exacerbates the problem. Alluka's voice breaks into a sweet moan before she inhales sharply. "Oniichaan..! That feels so good...Uhh, I, um..got all stiff and achy.." She ultimately opts to confess to him, knowing she wouldn't be able to keep it a secret for long.

"Can you please help me make it go away?" Alluka asks, her lower lip trembling at her request.
