Not a true swap yet...

Sammy had a wicked though. She went back for her own jeans and panties, she took them to Nina. The girl was in the bottomless state that Sammy had left her in and toyed with the idea of leaving her that way but she decided to toy with her pray. She pulled the cum soak panties up onto Nina's ass, she did the same with the jeans and put all Nina's things back into the cum soaked jeans. She was sure to thing she had done it, to finish up the prank Sammy lay Nina on the ground. She put the girl on her back and put her hand in the panties, making sure to lube the hand. She closed Nina's eyes, then time restarted Nina would think she had passed out after fingering herself in the school corridor.
