((SFW - Starter/Prompt)) - This wasn't exactly how Donatello envisioned his downtime, but he was willing to go along with it if it brought you joy. The small smile on your face as you painted his nails was endearing, and he couldn't help but smile back, feeling a faint blush creep across his cheeks from the prolonged contact. It had been nearly an hour since you started, making it the longest anyone had ever touched him. Even his brothers hadn’t managed to hold his attention for this long. Strangely enough, it felt quite comforting for the young inventor.

However, Donatello was beginning to feel a bit restless. The silence between you was starting to weigh on him; it felt too quiet. He could almost hear the hum of electricity flowing through the wires. His free hand started to tap against his thigh as he sat cross-legged on his bed. It was a little stim he used when he felt either understimulated or overstimulated, and right now, he was definitely on the understimulated side.
