Imaizumin-chi wa Douyara Gal no Tamariba ni Natteru Rashii Episode 2 , English
A high school guy is one of the first people in class that started living on his own. For some reason it attracted a lot of his female class mates as they can come and go whenever they like, and stay for as long as they want. It became the hang-out place for almost all of his female classmates. Lucky for him, these female classmates are extremely horny girls.
