A pervert who has been digging into a girl's anus for days, feeling her buttocks dilated by finger insertion and then being anally penetrated by a schoolgirl (NHDTB-785)

Every time I encounter a beautiful high school girl with a great butt on a crowded train, I give her anal stimulation! I play with her cute little buttocks, then use my fingers to insert and dilate them! At first, just one finger is painful, but as time goes on, it becomes two, three... even foreign objects!! Before she knows it, she's blossomed into an extremely masochistic anal sex site! Her violated anus uncontrollably experiences repeated orgasms! Finally, I ejaculate a large amount of semen into her contracting, beautiful anus!!
