Darashinai Onee-san wo Kaitai

One day, Haruto-kun, a junior high school boy who loves to help others, encounters a half-naked lady by the roadside! Her room is a mess, she won't wear her clothes properly, and when she's drunk she does all kinds of risky things for a lady. Haruto just can't help but want to help her! Without realizing it, he's taken up the challenge of being this older girl's caretaker...? Do you like a sloppy older girl who is even cuter♡ when she is unaware of her sexuality?
