Broomi will check if other clothes of hers work to help her brother

"Hmmmm," Broomi murmured, looking down at her habit again. "Have you ever tried using other clothes of mine? Probably so, right?"

"... Yes," her adopted brother responded quietly, mumbling through his fist as he stared out the window, determined not to look back at her.

"Which clothes?"

"... Socks. A shoe one time. Your rosary. Your wimple. Your hood. Your pajamas, back when you wore them," he continued, listing them off one after another. "They work too... To slightly different degrees."

"Aaaaaah! You masturbated into all of that?!" Broomi gasped, now growing red-faced. "Eeew! What the heck?!"

"I-I only used dirty ones that hadn't gone through the laundry yet!" he protested, now rejoining his eyes with hers so that he could defend himself. "They were still smelly, so I knew!"

"You smelled them?!" Broomi further questioned, her mouth hanging open in shock.

"I had to! You pile them all in there with the clean ones, I can't tell which are which!" he defended, clenching his teeth.

As Broomi ran through the list, counting off the articles... she came across an obvious, notable exception. "Wait... did you smell... did you use...?"

"No!" the boy clamored, suddenly looking her junior as his eyes widened and he waved his hands in protest. "That's the one thing I never did! I knew that if I did, I was crossing a line, so I never jerked off into your panties!"

"Or bra?"

"Or bra!"

She crossed her arms and stared at the ceiling for a moment, consulting Geod for the right way to advance. He was as silent as ever... she really did suspect that the church's high priestess and counselor were just making things up when they said they literally heard the maker's voice. Finally, she came up with the answer on her own. "Well, maybe you should."

"... E-Excuse me?" the boy stammered. She could tell from the way he'd suddenly shifted his stance that his hidden incubus dick had to be bothering him again.

"I said maybe you should!" Broomi repeated. "I'll go grab some from the wash-"

"There aren't any."

"Why are there not any?"

"I washed them earlier."

"Whyyyyy?!" Broomi complained, grabbing her brother by the collar of his shirt and shaking him back and forth so that his lengthy black hair and his pendant both flapped about his neck. "You never wash clothes! Why today?!"

"I had to put a load in! I came all over your dirty habits, remember?!"

"Eeeeeew ew ew!" she groaned, nearly tossing him out the window as she pushed him backwards and against the shutter. "You have to tell me things like this!"

"Like hell!" her sibling complained again, unable to imagine a scenario where he straight-faced told his sister that he'd need to borrow all of her used clothing in order to squeeze out his over-sized demon cock into them.

Still angry, Broomi thought up the best solution to the problem. They needed to test if a pair of her dirty panties did the trick, as far as providing relief from his cursed demonic erection.

"Ah, Sis... You might actually want to go grab a pair of clean ones. I think that when you fainted earlier, you uh... peed yourself," he finally got around to telling her, focusing his attention back outside the window again as she dropped her grip on him.

She drew back, aghast... Broomi was mortified at the fact that her brother knew about it, but also, because it made the next step of their experimentation pretty clear...
