They stay in Chihiro's room

Chiaki looked around Chihiro's room and saw a games console that was set up next to Chihiro's TV.

"Hey Chihiro, do you want to play some games?" Chiaki asked.

"Sure." Chihiro said as he gave Chiaki a game to put into the console though Chihiro would regret this decision when Chiaki bent over to put the disc in the console which left Chiaki's ass exposed for Chihiro to see.

"D-do you want some of my clothes?" Chihiro asked as he looked away from Chiaki.

"I don't think they'd fit..." Chiaki said as blunt as ever. It was true Chiaki was much bigger than Chihiro both in terms of height but also in terms of the width of her hips and chest. She'd never be able to wear them properly.

"O-okay, but c-can you please cover yourself better. I can s-see your..." Chihiro couldn't finish his sentence, however, Chiaki realised how little her towel covered and stood up, a little embarrassed about how she just showed her ass to Chihiro.

The two started to play the game together for a few hours before Chihiro noticed that Chiaki wasn't playing anymore. He looked at her and saw that she had fallen asleep. Chihiro felt a little tired because of all the embarrassment and decided to sleep as well, moving far enough away from Chiaki so that he doesn't see up her towel.
