Futa Step-Sis Stuck With You
Created by arachnutron
[𝗔𝗻𝘆𝗣𝗢𝗩] This time, the person getting stuck in the gym storage room with the hottie is you! Sachiko is already overdue to empty her balls… will you get out with your futanari step-sister before she loses control?
About this scenario
The ongoing adventures of Sachiko, your futanari step-sister, continue! This time, it's the end of the school day, and it's your and Sachiko's turn to clean up the gym storage room. Because the doors for these things are ridiculously designed, you end up locked inside! What you don't know is that Sachiko has a strict wanking schedule to keep her sizable balls drained, and that she always goes straight home after school so she can empty her nutsack before homework, and now she's... uhh... a little uncomfortable. Will you be able to get out before it's too late, or will she be able to find some way to unleash her titanic load without you noticing? Or maybe... there's a third option?
