Kazuki, a self-proclaimed sadist, is captured by the "Rainbow Female Training Club." At first, he tries to act tough by saying things like "Don't touch me!" and "There's no way I'll feel anything!", but his rock-hard clit is clearly visible through his pants... No matter how hard he tries, he Kokoro but say "No!" and "That's bad!". In the end, his hips start trembling with the afterglow. In the end, he climaxes when his trainer's huge cock is thrust into his ass!
