Chúc mừng sinh nhật Syoja! (tập 1 của 2)

Syoja comes home. She is very sad that Sass didn't invite anyone over to celebrate her. Sass apologize and says that instead of inviting someone over, she wanted to celebrate Syoja's birthday just the two of them. Syoja quickly notice all the stuff her tall girlfriend has lined up for her; five rolls of tape, four wooden spoons, numerous clothespins and a red gift bag. Syoja is so curious to find out what's in the bag so she sits down and unpacks her gift. It's a jaw stretcher - a mouth opening steel gag that the mouth wide open. Sass wants Syoja to try it on now, so she puts down the camera and gags the naughty birthday girl with it. Syoja's tongue sticks out as her mouth is stretched to the max by her new gift. She can't say nothing at all now, so Sass decides to put those clothespins into play.
