I, who had been troubled by premature ejaculation, consulted my older brother's girlfriend, AIKA-san, and got into an unexpected situation...! AIKA-san said, 'Talking isn't going to help!' and pulled out my penis to start the diagnosis! With her flashy nail-tipped fingers, she checked the sensitivity and began a slow, twisting blowjob! Unable to endure it, I ejaculated slightly early, but she continued as if it were training, forcing me into consecutive strong ejaculations! The improvement for premature ejaculation came through practical experience with a large butt piston, causing an explosive internal ejaculation! Even after that, with a series of merciless techniques, I ended up ejaculating repeatedly! #Class Leader P
