[A superb experience that melts your ears while being sandwiched between four beautiful sisters! I was invited to Mitsuki's house, a junior college student. So, from a lot of things, I decided to have a reading party with her sister and sister ... but the content was a sensual novel written by their mother! ? Are the humanities sisters really carnivorous? The limbs are restrained and there is no escape! The head is in a trance state with an indefinite language that is beaten at the ears ... the lower body is inserted instead of being squeezed many times and runaway!
