◤TRACK_01 ~ Prologue / The Young Master's Superhuman Plan Begins

I will avoid repetition. From morning till night, education continues for a whole month. Oh? Young master? You haven’t heard anything about it? My deepest apologies. It seems there was a failure in communication. In that case, allow me to explain once again. Young Master’s Superhuman Stamina Plan The plan to transform Young Master’s penis into an ultra-strong, ultra-enduring, massive cock. The one entrusted with this task is none other than myself, Yūmu. I was once called the strongest “Kunoichi,” but I have already retired from the front lines due to fortunate circumstances. However, when it comes to insect-repelling techniques and techniques using the female body, I still proudly consider myself fully active. With my plump, soft breasts that you’ve touched, and my tight, dripping wet pussy— Squeezing real flesh tightly, or using skilled vaginal techniques to grip and milk the shaft— I will do my very best to please Young Master’s cock. Enough small talk for now. Young Master… Have you ever touched your own penis before…? Of course you have, right? Then… have you ever experienced someone slipping their hand into the gap of your clothing and fondling you inside…? Good night— How does it feel? My slow fingers entwining around Young Master’s cock. Touch… touch… Stroke… stroke… Squeeze… squeeze… Stroke, grip, tease… The precum is starting to flow… Yes… it’s coming along nicely… I’ll take it off now… Could you please lift your hips…? Thank you… So big… Such a magnificent Young Master cock… There’s no need to be so embarrassed. I’ve even seen Young Master’s little pee-pee back then, you know. Now it has grown so splendidly— no longer the cute little thing from before, but a proper, virile man-cock… Such a lewd, musky scent… The shape, the size, the smell… Truly excellent. As expected of Young Master. Now, to make it superhuman in stamina— This hot, rock-hard cock right now must be quite painful already, isn’t it? Then, as the beginning of the Superhuman Stamina Plan, we start with the basics. Like this… Gripping it tightly as if strangling the glans… While stroking… Stroke… stroke… stroke… Stroke… stroke… stroke… The heat from Young Master is transmitting through the palm that’s sucking onto your cock. Deep breath— 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17… It probably feels like there are countless fingers. Slender, moist fingers wriggling as they coil around the shaft, sucking you in. Young Master, this is my secret vaginal technique. Please do your best to endure. Since today is only the first day, this is still just the opening act. I didn’t expect you to leak precum so much while I lick your ear, but rest assured— I know exactly how to pace myself… I won’t make you cum quickly… Good night— This ear too, and of course your cock as well… Shake… suck… Young Master, are you already at your limit? Your cock is throbbing so violently it’s about to burst, and I can feel from my hand the semen rising from deep inside your balls. It’s okay, Young Master. Release it all into my hand— shoot as much as you want, byuu—! Stroke stroke stroke stroke Pyuu— You did very well… Young Master… So much… you released so much… From now on, we will train you thoroughly to aim for the strongest, toughest, biggest cock.
