Rasen Kaidan Scenario II

This is the 2nd installment of Spiral Staircase, an adventure game that specializes in cum bukkake.
You progress through the game by staying overnight at a Shinto shrine you visit and joining up with two other men to have sex with a girl.

As each character's stamina meter goes down to 0 they will cum as soon as the sex comes to an end, though the main character also has the option to cum any time he wants to. The scenerios and bukkake paterns change based on which characters are cumming at the same time. For example, if all 3 guys cum at once then the girl will end up soiled by 3 men's semen.
Additionally, the cum she gets covered with will stay on her throughout the sex scenes that follow.
