A pair of serious glasses girls who usually just study. But actually, Mutsurisukebe. When such two people took off their squirrels and drank at home, they messed up ● and mischievous to their sleeping brother-in-law! At first, it was a cute mischief such as licking the face and ears, but the mischief is escalating more and more, which one can do more amazing, such as nipple licking, belochu, handjob, etc.! Even if my brother-in-law wakes up on the way, mischief continues! At the end, two people commit a confused brother-in-law!
