Prescription for Sex 1

The girls on the student council have started noticing how much time Yumeko is spending in the nurse's office lately. Yumeko was always delicate and frail... until she started having the special treatments from Mr. Murakoshi. Now she's become surprisingly genki! What the other girls don't know is Murakoshi has been increasing Yumeko's energy by recommending daily masturbation, doggystyle fucking, as well as frequent doses of his semen in nakadashi creampies! Student council president Sayuri is curious to know what's been going on in the nurse's office, and when Murakoshi calls the whole student council down to the gym to play his special game, she's about to find out for herself!
