Toromitsu Musume no Hitou Service: Torottoro Churu Churu Gohoushi Sasete Kudasai

Synopsis

After successfully purchasing a cheap car with the earnings he made from countless hours of part-time work, a certain man can finally go to the hot spring inn he has been wanting to visit. However, he gets lost on the way there and instead stumbles upon a secret hot spring where he is welcomed by three cute girls—Hazuki, Amane, and Hina—who promptly give him a mushy, slippery, and gooey "service" comparable to heaven on Earth.
