Sauna

You head into the sauna to check out if there's anything strange. As you enter you go into the changing room. There are some lockers in the room and it looks as though two are in use. There's nothing else suspicious though in the room.

You take a peak through the window in the sauna door. You look on one side but there's no one there. As you turn to look on the other side you notice there are two people on one of the benches 'Jesus' you exclaim as you realise what's going on.

There's a woman lying down and a man on top seems to be fucking her tits. You can't make out either of there faces though.
