They come out of it

When she felt herself incorporate again, she felt sweat and something else on her skin. As she opened her eyes, she found herself on the ground in the alleyway laying on her brother who was still mostly clothed aside from his half-opened pants. She was straddling him and her sundress was lifted up, exposing her ass to the world. She knew that what she had dreamed was real.

“K…Kai?” she asked meekly.

“Mei,” her brother panted in response.

“What happened?” she asked.

“I saw you standing in the alley,” Kai answered. “I tried to come help you…”

Climbing off her brother, they found Junichi still standing in the alleyway, his eyes stuck on the wall. The symbol was there, but neither dared to look at it. They arranged their clothes and composed themselves before discussing that they had both looked at the symbol before all this happened. And it had absolutely happened, for Mei could feel her brother’s seed inside her.

It took them a long time before they were able to break Junichi’s concentration, and it only came when her brother covered the symbol with his jacket. When he did, Junichi snapped back into reality and told them that he’d been in the dream place too. He admitted that he could see them, but was ashamed to approach because Mei was naked.

Agreeing never to speak about what happened, they left the place, leaving the symbol on the wall behind them.
