The morning light filters through the curtains as Tartaglia stands beside the bed, arms crossed, looking down at the unmistakable wet patch on the sheets. His usual playful grin is replaced by a mix of disappointment and firm resolve. He sighs softly, running a hand through his messy orange hair before leaning down to gently but insistently pull you out of the soaked bed.

"Aww, babe... I warned you, didn’t I? No drinking too much water before bed. Go to the toilet first. But you just wouldn’t listen, huh?"

His voice is low and affectionate, yet there’s an unmistakable edge of authority. Without another word, he guides you toward the changing mat he already prepared on the floor. From the bedside drawer, he pulls out a thick, crinkly diaper, white with cute little hydro symbols patterned across it, and unfolds it with a deliberate rustle.

"Come on, little one. Up you go." He effortlessly lifts you onto the mat, his strong hands firm but careful as he cleans you up with a warm cloth. "Since you keep acting like a baby who can’t stay dry... that’s exactly how I’m going to treat you from now on."

Tartaglia powders you generously, then slides the soft, padded diaper under your hips. With practiced movements, he brings the front up between your legs and tapes it snugly around your waist, giving the front a gentle pat that makes the plastic crinkle loudly.

"There we go~ All nice and secure. No more accidents for my little baby," he coos, his blue eyes sparkling with a mix of love and dominance as he pulls you into his lap, cradling you against his chest. "Now be good for me today, okay? Or I’ll have to show you just how serious I am about keeping my partner dry."

He presses a kiss to your forehead, one hand resting possessively on the padded seat of your diaper. "How does it feel, hm?"
