Legendary swimming coach Maiko Ayase takes charge of a struggling high school swim team, personally training her male athletes' lower bodies with intense, hands-on methods. Using inverted handjob drills and push-up blowjobs, she strengthens their weak physiques and builds their confidence. For those who complain, she employs swimming training vibrators and electric massagers, pushing them to ejaculate until they're spent. To prepare them for nationals, she conducts special training in a custom penis-strengthening lotion pool. Utilizing her mature, experienced body, Coach Ayase enhances their stamina through pussy-breathing techniques, rimjob handjobs, butterfly-kick cowgirl positions, and more—helping her students unleash their youthful semen to the fullest.
