One day, while taking a walk, Lehto met a rabbit-like animal. When you look into the well indicated by the rabbit, you're headlong to the bottom of the well. Before I knew it, I was in front of a castle I had never seen before. It was a rate that made me nervous when I was suddenly approached by a beautiful and big sister, but there was a dashing helping hand. "I'll lend you my strength. Do as I say♪" That's how it started with a somewhat naughty wrestling. The older sister who helped me, Louis, did what she said, and it was a rate where she touched her breasts and dicks with all her might. Will Leto be able to return home safely?
