Kana was asked by her sister, who is going on a trip with her husband, to take care of her nephew. At first, the nephew was well-behaved, but he started to fixate on Kana's unguarded breasts and went wild! The nephew, while being affectionate, greedily latched onto her breasts, claiming it as a merger and committing rape! He invited friends over to his house for a merging game with everyone! Claiming it as a detective game and committing restraint rape! Kana was driven to orgasm by the rough yet innocent sex of her nephews! 'I get it now! When sister says "go" it means she feels good, right? Take this Mach Piston!'
