在她作为快递员上班的第一天，Tenjou 要把当天的最后一个包裹送给一个非常特别的客户 Isis，一个想要开始当女施虐狂的年轻性感的女孩，几天前她买了一些玩具准备开始当女施虐狂，Tenjou 刚刚把它们送到了她手中。Isis 很不耐烦，想在遇到的第一个人身上试用她的玩具，那个人就是给她送玩具的快递员 Tenjou，她抓住她并将她推到房间的床上，Tenjou 什么都不明白，Isis 用胶带和她的力量，将她的双手绑在身后，用她的新口球塞住 Tenjou 的嘴，这样她就无法寻求帮助或尖叫。Isis 很喜欢捆绑，这让她兴奋，她将 Tenjou 的胸部和手臂绑在身上，让他动弹不得。然后她绑住她的腿，将脚踝与大腿连接起来并进行修改。

将信使受害者绑起来后，她拿出了最兴奋的新玩具——假[X_X]，她想第一次用它塞住天城的嘴。她解开口塞，把整个假[X_X]塞进天城的嘴里，玩弄着她的小嘴，天城用假[X_X]好好地[X_X]了几分钟，直到永远。

完成后，伊西斯准备了另一个游戏，她拿出新的绳索，把天城的胳膊和腿绑在床尾，这样天城就被固定点束缚得更加紧绷，无法合拢双腿。On her first day of work as a courier, Tenjou has to deliver her last package of the day to a very special client, Isis, a young and sexy girl who wants to start as a dominatrix, days ago she bought some toys to start as a dominatrix, and Tenjou just delivered them to her. Isis is impatient and wants to try her toys with the first person she comes across, that's Tenjou the messenger who brings them to her, she grabs her and pushes her against the bed of the room, Tenjou doesn't understand anything, Isis with duct tape and her strength, ties her hands behind her back, and with her new ballgag gag, she gags Tenjou's mouth so she can't ask for help or scream. Isis enjoys tying up a lot, it excites her, she ties Tenjou's chest and arms around him so that he can't move. Then she ties her legs, joining her ankles with her thighs and modifying them.


Once she has her messenger victim tied up, she takes out her new toy that she is most excited about, the strapon, she wants to use it for the first time with Tenjou's mouth, she removes the gag and puts the whole strapon in Tenjou's mouth, playing with her little mouth, Tenjou gives a good blowjob to the strapon for a few eternal minutes.


After finishing, Isis has another game prepared, she takes out her new ropes and ties her arms and legs to the ends of the bed, so that Tenjou is even more restricted with the anchored points, making her unable to close her legs.
