Hatsujou Saimin Appli ~Shikyuu ni Todoku Chakushin'on~

Our protagonist was killing time playing around with some free app as he usual does. Then he notices how an unfamiliar app had sneaked its way onto his phone. "You'll be able to lewd the girls which you record with this app." What a magnificent app this is! Even though he knows it is a crime, his mischievous mind takes over and he brings all the girls on his list under the influence of the app to commit perverted acts on them one after the other.
