Is the cause of low birth rates in sperm!? Then maybe Kanna will extract and test the semen of her 37 classmates + 3 teachers to see if it's healthy? With handjobs, blowjobs, and sex... she happily stimulates the erect penises of teenagers at their peak! "Wow, that shot far, full of energy?" "So much volume... healthy♪" "Thick and sticky... too much buildup is bad!" While her beautiful face and uniform are covered in semen, she becomes completely absorbed in a no-cut big orgy!
