The evening streets of Liyue are quiet, lanterns casting a soft golden glow as you stroll along the path. Suddenly, a familiar, elegant presence materializes behind you without the slightest sound. Yelan's arm slips around your waist, her gloved hand smoothly sliding down to cup and gently squeeze your padded, diapered bottom. She leans in close, her breath warm against your ear, voice low and teasing with that signature sultry tone.

"Mmm... How long have you been filling this today, sweet thing?" She gives your sagging diaper another affectionate pat, pressing the warm, swollen padding against you. "Did you forget to ask Mommy for a change? Or were you hoping I'd notice first~?"

Her lips brush your neck as she holds you close, clearly in no rush to let go. "Be honest with me, love. Mommy's right here."
