In a certain deep forest, there is a girl walking alone. Her name is Alps. And this is a dangerous forest where many terrible creatures lurk. But Alps is frightened and goes on her way. To save her sick sister, she continues to walk out of the forest with a medicinal herb in her hand. Alps is still walking, "Wait for me. Sister". However, the forest is not as sweet as one's determination. A big monkey in heat forced her to sow her seed, and a boar attacked her with his huge body. Furthermore, she also encounters a group of men of dubious character.... The lone, dainty girl is nothing but food for the beasts. What will be the fate of Alps?... Alps wanders through a dangerous forest to save her sister. Her white soft skin emerges in the dimly lit forest. The huge body of a boar, a big monkey in heat, rests on it. A glossy pink color emerges on her heated body.
