Chihiro comes up with an excuse

"Aoi!" Chihiro called out, trying to get her to stop.

Finally, Aoi stopped moving. "What's wrong?" Aoi asked looking down on Chihiro, seeing her naked classmate with a bright red and seemingly aroused face looking up at Aoi while resting between her naked breasts was something that made Aoi's embarrassment amplify immeasurably.

"I..." Chihiro froze, he could tell Aoi why he stopped her but if he didn't say something then she'd start running again.

He turned his head to his side and saw the doors right next to them. "I need to pee..." Chihiro lied, if he can get some privacy then he can sort out his issue.

"Okay..." Aoi replied as she changed her direction and walked into the Girl's Bathroom.

'Wait!' Chihiro wanted to protest but saying that he didn't want to be taken into the girl's bathroom would cause more issues than it's worth.

Thankfully, the bathroom was empty so the issues with someone finding them naked in here.

Chihiro had never been inside of the women's bathroom, he had always just gone into the men's room when no one was around or just held it until he made it back home.

Chihiro looked at Aoi. "Can we please get these ropes off now?" Chihiro asked, praying that Aoi had a plan.
