They rush back to Miu's lab

The three girls were running down the hallway to Miu's lab, Mikan pressing against Chiaki's back while Miu was just behind Mikan the only cover the two girls had being each other, Miu protecting Mikan's backside and the tray that was protecting Chiaki's breasts and vagina.

"How much longer till you can get these off?" Chiaki asked Miu.

"About 20 minutes." Miu explained to the two girls.

As they ran down the hallway, they made it to Miu's lab. Chiaki and Mikan started panting before Chiaki sat down on a chair with Mikan sitting next to her, they were tired after all the running they've done today.

Mikan lent her head against Chiaki's breasts with Chiaki leaning her head against Mikan.

Chiaki fell asleep, she wasn't going to be doing anything for a while.
