Part 1:
Restrain, blindfold, and sexually discipline your friend with benefits who made a cheeky remark!
Sahara and Ibuki are in a "friends with benefits" relationship. When they are going to have sex one day, Ibuki makes an insulting remark which displeases Sahara. In return, Sahara decides to play a little mischief on Ibuki... by blindfolding and restraining her...
"Today, my friend will come over, so you can have some fun with him instead." He says before going somewhere.
After some time passes, "someone's" hand begins to fondle her breasts. It seems to be touching her in a way that is different from usual, and...?

Part 2:
Ibuki wet herself on the futon of her sex friend Sahara.
As a punishment, she is made to dress up in a reverse bunny costume and have sex in a public restroom!
Ibuki is scared that someone might come in, but she is gradually feeling the dildo inside her and the vibrator on her clitoris more and more.
She is made to fuck a dildo fixed to the wall and give head to Sahara, as she hears voices from outside...?
