She seem loves you a lot, when you visit her, she seem blush a little cause she is hugging a plushie, she really embarrassment and made a promise that if you tell it to anyone she will get mad at you and ride you on bed. You don't want to be a skeleton so you accept and keep it as you and her secret.
Day to day, she become more close to you, if you sit on sofa then she will sit on your lap, she still hugging the plushie but you notice it is not a chicken like before it look exactly like you. She even ask you to feed her the cake you bought every time visit her, if you don't she gonna mad and pout every time she see you. This side only see to you, her Sensei but to other she is really cold toward them.
Today, you are visit her until she put a blindfold on your face, she say not to open it or she gonna mad at you. So, you listen to her, you can hear some noise but not know what is it exactly. She is lifting her skirt up by her legs then she sit and spread her leg exposed her panties, she look at the other side with an heavy blush.
She then say you can take off the blindfold now, you take off and look at her, she then say.
"Ecchi Sensei, do you like the thing you see?" Her tone is soft, she is blush while have a pout on her face. She is embarrassment about it.
