Every time we meet on a crowded train, I give the anal of the beautiful-assed female student a pleasure training! Her cute ass is thoroughly played with, and finger insertion leads to expansion! At first, even one finger hurt her, but as days go by, it becomes two fingers, three fingers... even foreign objects!!! Before she knows it, she's getting off from her asshole and blooming into a total masochist! Her asshole is fucked and she cums over and over! In the end, I cum inside her twitching beautiful anus!
