After a grueling day of leg training at the gym, I returned home and rushed into the shower. I washed away the sweat and grease accumulated from the intense training, and my muscles finally relaxed in the warm water. The water flowed down my legs, and my quadriceps still maintained a strong pumping sensation due to the previous intense training. I flexed and extended them, showing off my muscular pumping sensation and enjoying this pleasure.

I'm not sure if it's because of the blood circulation in my legs, or because of the current desire-driven urges, but my other bulging penis, with its veins standing out, twitched along with my contraction - as if it too was craving a blood pump of its own. A sharp pain traveled from my scrotum all the way to the tip of my soft penis. The steaming water continued to flow down my body, and I sighed softly.

After enjoying a few more minutes in the hot bath, I finished my shower, dried off, and lay down on the bed. There has never been a better and more relaxing feeling than after intense exercise and a refreshing shower. I closed my eyes, lay for a few minutes, and completely relaxed. The flaccid penis rested against my stomach, and the short pubic hair dried in the refreshing air. My quadriceps began to relax, and the blood flow in my legs returned to normal. But these excess blood had to go somewhere.

I lay there, feeling the blood slowly flowing from my legs to my third leg. There is nothing more wonderful than the feeling of an involuntary erection. Although it's not like an orgasm, it feels like an electric shock. I remained motionless, immersed in this sensation, and my penis took over everything, pumping blood and expanding to its maximum size. A series of throbbing sensations made me feel the blood flowing in, and the sensitive skin of my penis also stretched and moved. The refreshing air continued to stimulate my now extremely sensitive, hard-as-stone penis.

Gradually, my penis began to crave more attention, not just the fresh air and the flow of blood. To maintain this sensual sensitivity, I restrained myself from touching my member. I slowly pressed the base of the penis with my thumb until it stood straight up towards the sky. I was intoxicated by this additional pleasure, my skin was further stretched, and the blood vessels became so thick that they seemed about to burst. Maintaining this position, I moaned, and the pleasure flowed up and down my penis from that extra pressure point.

I admired my tall and erect penis, which was standing straight and ready to be penetrated by my future wife. Imagining her gentle hands encircling the base of my penis and squeezing it, guiding it into her vagina, was truly a delightful thought. This idea once again sent a wave of pleasure surging through my engorged penis; I'm certain that when my wife places her moist scrotum on my erect penis, I will have the same reaction. To imagine her love fluid flowing on my penis, I used my other hand to apply saliva under the swollen glans.

Because of this slow accumulation, every slight thrust would send shockwaves through my body. I continued to thrust while imagining sharing that pure ecstasy with my wife one day. Eventually, I couldn't bear it anymore; my penis had reached a point of no return. I had to end it with a loud bang. I spat all my saliva onto my hand, smeared it all over my penis, and then thrusted like a madman. My other hand continued to rub the base of the penis, using the same motion to tease my genitals.

With the interweaving of these sensations, my testicles began to hurt within just a few seconds. Just like the feeling of blood flowing in the penis earlier, now I felt the semen rising in my testicles and then spurting out along the length of the penis, gushing out from my penis. I remained standing upright, and the twitching penis sprayed waves of semen into the air, splashing onto my chest, legs, and penis.

It felt like I emptied the semen from my scrotum twice. Finally, I slowed down the speed of my masturbation and started to calm down. My penis was still throbbing slightly and twitching, and it was still trying to recover. I relaxed again and felt relieved all over. My breathing was as rapid as during training, and I couldn't help wondering if this should become my routine action after each leg training session.
