[The angle of insertion under the skirt is too erotic...] A close junior in a long skirt is sitting on top of a senior. From the outside, it seems like an ordinary day. But what if she's actually inserting herself in a cowgirl position under the skirt... It seems like a lie, but it's an immoral situation that is not impossible in reality. If a junior who is as cute as an idol seduces you in front of your girlfriend by saying, "If we do this, no one will find out," and even secretly inserts himself into her... Can you resist the temptation?
