Nozomi, a female teacher whose breasts have grown since she gave birth and her nipples have become unusually sensitive. Because of the nipples that I can feel just by touching them, I can't even do classes. Students who adore Nozomi devote themselves to nipple torture and try to encourage her libido. However, the sensitivity of the nipple increases to the extent that it is blamed, and the desire that can not be suppressed further escalates! ! Sensitive nipples make serious teachers go crazy, students get involved and fall into an obscene world! !
