Snow Lodge kara no Dasshutsu -Escape After Sex 3-

Yuki is your one year junior childhood friend, and at the same time your lover.
On a Christmas day, you and she come to a rural snow lodge for snowboarding.
Here you and she are set to challenge an 'Escape Room' session by the owner
of the lodge. In an easygoing mood, or perhaps in a flirty-dirty mood, you and
she go on an Escape Room game without a feeling of tension.
