Gohan had no sense of boundaries. He sought out sensations, sensory stimulation of a thousand different types. The boy had been known to get stuck in small spaces seeking pressure and touch.

Piccolo both desired and feared physical contact.
He had all sorts of boundaries.
To him, Gohan's lack of such barriers was both alarming and... Comforting? Piccolo was unsure.
So when the boy clambered up into his lap, he froze, not sure what to think, how to feel, how to react. Gohan sat there silently - as usual - leaning back against Piccolo's chest, a book in hand. It was a large photography compilation of wild animals. Gohan looked up at Piccolo, his dark eyes seeming almost impatient, as if his impromptu chair was inconveniencing him by not helping with the massive book.
Gohan liked to be cuddled, to feel steady pressure around him.

The law student glanced at Chichi, looking for some sort of help, a nod of reassurance, something.
Their eyes met for a brief moment, and she smiled softly.
He swallowed, and slowly looked back down at the child, and gently helped Gohan to hold the heavy hardcover.
