Plump J-cups spilling out of competitive swimsuits Swimming club advisor, training camp passed around by students Aya Ueba
In the middle of summer vacation, Aya, who works as an advisor for the swimming club, came to a training camp with her students. Contrary to Aya's enthusiasm for the national competition this year, her students, Ariki, are only interested in Aya's swaying, estimated J-cup breasts. Instead of concentrating on club activities, Ariki and his friends are busy watching Aya change clothes and take a shower. His evil plans don't stop there, and he plans to confess to Aya and have sex with her at night. That night, Aya notices Ariki and the others' plan and scolds them. However, his voice did not reach the excited students, and they resisted in vain.
