The female students can't resist because they have no one to talk to. Special instruction after school... Their moans echo in the closed room where they are alone! Their nipples have been developed and they arch their backs in ecstasy just by stroking them with their fingertips! They can't stop playing with their nipples... They're addicted to nipple orgasms! It feels so good that they're dripping saliva and love juice! "Teacher... Please make me cum more and more..."
