HUNTC-601 My serious club-member younger sister retired from her club activities and her energy and desire are overflowing! Instead of exercise, she uses me for intimate training! After my sister, who had been devoted to club activities, retired, she had so much energy and desire that she spent every day relieving stress on her own! But that alone wasn’t enough, so she turned her pent-up feelings toward me and kept pushing herself to the limit again and again!

My younger sister spent every day buried in club activities, with morning practice and after-school training. That serious sister, who devoted herself to her club, has now retired. During her active days, she used club activities to relieve stress, but after retiring she began staying in her room more often. When I peeked inside, I found her repeatedly losing herself in intense self-pleasure. Was all that leftover energy going nowhere and turning into overwhelming desire? When I secretly watched her like that, she noticed me. I quickly apologized, but something about her was strange… In truth, she was directing all the desire that self-pleasure alone couldn’t satisfy at me! With my sister overflowing with energy and desire, we ended up drenched in sweat and driven to the limit again and again. She pushed my body hard, even though I’m bad at sports and have below-average stamina. Please, I can’t take any more!
