Ear Licking Heaven 4 ~Hot Ear Licking in Various Situations~

Rumilla (CV: Gemiko Yamada, Hina Yuzuki)

A young and somewhat annoying succubus. She's been talking with her friends about just how far a human could be corrupted with ear licking alone, so you get to be her test subject.

Karin (CV: Chiyu, Yu Kawase)

A gal-ish college student. Like her friend Miina, she's into younger guys. When she likes somebody, she tends to make the first move. She thinks of herself as less prone to going overboard like her friend, but in reality they're similar. The pair of them are on a trip to the beach when suddenly they spot a guy they like...

Miina (CVs: MidorinoLime, Minase Suzuka)

A gal-ish college student. She's into younger guys and gets really turned on by their innocent reactions. Along with Karin, she likes to roam around town and hunt for boys. And similarly to Karin, she just can't help but make a move when she spots one. If she's having fun, she's satisfied, so she's just a little selfish...

Ruri (CVs: Yuusa Mibuki, Sakura Kigetsu)
Your older sister. She's a quiet, gentle type who works in an office.

She's been helping to cheer you up for years, usually with ear licking. She's a bit worried that you're getting spoiled, but is happy that she's still able to help you out.

Miwa (CVs: Rima Nemurine, NyaruPomupomu)
Your little sister. She's a student, but is much stricter than her spoiled older brother.

She tries to look out for you and is secretly in love with you. Her desire to get to you before Ruri isn't really working out, though... She tends to get caught up in her own emotions, probably because she likes you too much.
