Shojo Sotsugyou! ~Watashi de Doutei Sutemasen ka?~

"On this auspicious day of graduation, today, we... are graduating from being virgins.
To our teachers who guided us so kindly and diligently, and to our fathers and mothers who watched over us warmly, and sometimes strictly...
Thank you so much. Please watch... as we become adults!"

At the school's graduation ceremony, the male and female student representatives, with tears in their eyes, read their words of gratitude.

Amidst the enthusiastic applause, the "Virginity Graduation Ceremony" finally begins.

In front of a large crowd, the male and female graduates, now in pairs, expose their well-developed genitals.
