You hear noises in a room

As you were about to pass down another corridor, you notice towards your left an open doorway with a plastic sign on it. It read in foreign letters so you could not decipher what it meant, but the off white tiling and privacy wall just beyond the doorway definitely indicated some kind of communal shower or changing room, and from the sounds of running water, you could tell it was occupied. However, it was not the sound of water that caught your attention, but the distinct sound of a woman's voice inside along with splatterings of male ones. Listening closer, you could barely hear the audible sound of moaning coming from inside. Closer listening caused your heart beat to skip. It was a very familiar voice. You decide to risk discovery to confirm who you thought it was. Sneaking in, you peer past the privacy wall until you could barely see with one eye, remaining as stealthy as you could. What you see caused you to muffle a gasp, your hand flying over to cover your mouth.

Inside, you catch sight of a tall tanned skinned brunette, bent over with hands spread across the far wall. Behind her was an old local man with a pot belly, hands gripped around her E cupped breasts and rapidly pummeling her pussy with fevered thrusts. There were two other men in there watching, both of similar age, naked and stroking their erect dicks. You immediately recognize the woman as Nina. One of your travel buddies who was also Christopher's devoted girlfriend. Her raven like locks bounced all over as her head seemed to loll about with each thrust, as if in an intoxicated stupor. You cringe as her sultry, sexy voice rolled out, begging for the man to keep fucking her. You sink into a small squat as you see the man suddenly pump his hips roughly, letting out several **** grunts amidst her apparent cries of pleasure. As the man pulls out to step aside, you could see a stream of white drip onto the floor, the woman's well shaped ass wiggling about on display for the others to see. You hear her speak again, seeing her turn her head to grin widely. She begged them to keep fucking her and filling her with their thick cream. Her words came out without shame or remorse. Not even the slightly tinge of fear. From the look on her pretty face, she was clearly enjoying it all.

You felt the urge to edge away from the wall in shock. You knew her face, her lovely attitude and her eternal love for her boyfriend. What was going on? Why was she doing this? So many questions filled your head as the shock sets itself in. You searched for an explanation but came up with no comprehensible thought at all.
