Time stop: Honor student gets time stopped by a girl in her class and gets creampied by boys

Hikaru, the best in the class. I got an app that allows girls who are jealous of her to target her and stop time. The girls are a prank that makes Hikaru stop and take off her clothes. The boys piling up there flock to Hikaru. The mischief continues to escalate. Hikaru is forced to give him a blowjob, public urination, and then gets creampied one after another. She was the only person in the class who didn't know she was being fucked. . .
