This school has a unique position called "Service Duty"... The female students appointed become human toilets to take care of the boys' Kokoro, bodies, and sexual desires! They use their mouths, hands, breasts, pussies... the mucous membranes of their bodies to the fullest to make the big dicks ejaculate until they run out of sperm. A huge amount of semen is poured deep into the JK's vagina from the throbbing penis! A beautiful girl covered in milky liquid!
