I went to experience a fitness gym to relieve my lack of exercise, only to find it was a specialized penis training gym! The trainers are six instructors: Sakino Mizuki, Onodera Mai, Aise Yu, Arikari Nonoka, Mochizuki Tsubomi, and Sakuragi Mion. All are fresh, cute, and beautiful with excellent figures. Using unique training with gym equipment, they achieve everything from enhancing erection hardness and improving premature ejaculation to speeding up thrusting, realizing incredible recovery after ejaculation. With repeated edging through handjobs, blowjobs, and stimulation from their own vaginas, they harshly push limits with precise ejaculation control. No matter how many times you ejaculate, strong re-erection leads to ultra-stoic creampie sex training, and the male actor's struggle to gain a popular, super-enduring penis is highly engaging. The bright, laugh-inducing entertainment value is high, complemented by numerous full-nude scenes that add glamour, making it a work where you can fully enjoy the erotic elements. I actually watched it myself and felt an energy that exhausts physical strength, stimulating a desire to acquire a popular, super-enduring penis in one go.
