He decides to fully trust him with Rukia's nature!

"Hmm... this is interesting..." Urahara noted as he typed away at some sort of sensory machine the lamp was in. Ichigo, despite some misgivings, had decided to tell Urahara about the lamp, just to make sure no surprises were hidden in it. And of course, that Rukia was its genie. "I can't make sense of any of these readings. There's spiritual energy, yes, but also a bunch of other types I simply can't identify."

"Of course it's like that," Rukia explained. "As I said, the Lamp goes through the multiverse. It can adapt its magic to work in a variety of ways to suit the world its in."

Urahaha hummed and then said, "Makes sense... this is something way outside my areas of expertise unfortunately. Anyone's area, really. This is a classic outside context situation here," he rubbed the back of his head.

"Heh, but it doesn't seem like a bad thing," Yoruichi chimed in, wrapping an arm around Ichigo's shoulders from behind and grinning mischievously. "You got your hands on something that can enhance sexual pleasure without issue... you gonna use it on me?" she teased, giving him a wink.

Ichigo went beet red and moved away. "Um, are you actually inviting me to?" he asked her.

"Maybe!" she chimed. "It certainly sounds fun! Just don't do anything I wouldn't want done!" Yoruichi stuck out her tongue.

"And... how would I figure that out, even if I was interested?" Ichigo questioned.

"Oh, you have an easy way to figure out what I'm into, unless you can't figure out something that simple," Yoruichi sniggered. "And don't tell me you're not interested, you were so very flustered when you saw me naked!"
