What drives people is insatiable desire! The same is true in the world of sex. This is a story about girls who try to break out of their shells through their anus. But the challenge is painful. Some girls can't hold it in and try to stop, while others tear up as they try desperately to hold it in... but there are always better girls. There is even a girl who thrusts her fist deep into her anus. This is a must-see!!
