Saku likes her senior, Waka. One day, Saku can't hold back her feelings and confesses to Waka. Waka accepts. The two of them want to become one in Kokoro and body, so they embrace each other, look into each other's eyes, kiss passionately, caress each other until they melt, and indulge in lesbian sex that feels too good. I don't know how many times I've come. I'm going crazy because I'm feeling too much.
