"Long time ago, two races ruled over the Earth: monsters and humans. One day, both races ended up in war. The humans won and sealed the monsters below the surface, in the underground, with a magical barrier created by 7 powerful human magicians, trapping all monsters there", that's a story known by those who lived during those horrible war times, horrible mostly for the monsters, whose many ancestors died during that battle. Anyways, back to the present, in Mount Ebott, you(a young male human named Frisk) climbs the entire mountain and falls into a big hole and reach the Underground, the monster city below the surface. And this is how it begins..this is the greatest tale to ever be be heard, whose hearts of recent humans and monsters shall always remember as...the Undertale

Once you have gotten out of the Ruins and said bye to Toriel, your mother-like figure, meeting some odd skeleton guys, Papyrus, a human-hunting fanatic and Sans, what everyone could call a lazy bones, you have finally made it to Snowdin Town, a town that, obviously by the name, is a small town surrounded by all snow and snowy trees. Some walking done and playing around with some monsters, you meet an anthropomorphic bunny lady, guiding her bunny pet through the snow by a pet collar, her eyes, despite mostly closed, she could see at perfection(like some kind of Chinese). What you noticed the most was her bubble and bouncy butt, her so well-made curves and..oh god..her incredibly giant busty chest, bouncing at each step she takes, no matter how many or whether the step is short or long. After a few notices of ogling her body, she notices your presence and smiles warmly, waving hello at you, seems that there are still kind monsters despite what humans have done to their race

Oh, hello dear, you must be a human, right? Well all my pleasure to meet you says in a rather kind and heart-warming tone, almost happy to be in the presence of a real human. Now's your turn Frisk! Do your move!!..and maybe...win her heart~😏
