[F/M Tickling] The secret training I received from my basketball club senpai felt strangely ticklish...!? A discouraged male student struggling to perform in club activities is taken under the wing by a sympathetic upperclassman who offers him special private training. It starts with checking his shooting form, but he quickly notices the senpai's touch is soft—and unexpectedly ticklish. Every time she traces his arms with a feather duster used as a training pointer, he trembles from the sensation. "Don't you think you're lacking strength in these muscles?" she scolds gently yet firmly, escalating the tickling intensity. During leg exercises, she chides, "You won't catch the ball again like this," massaging his feet while adding teasing tickles. Ashamed of his weakness, the boy desperately tries to endure, but the senpai grows increasingly intrigued by his suffering. As training equipment ends up binding his limbs, she deliberately targets sensitive spots like his feet and armpits—never letting anything slip by. Recommended for fans of relentless tickling, psychological domination, and those who want to be tormented by a boyish, dominant female senpai!
