Gym

Soon you found Emma wearing her regular gym bra and underwear. "I have decided to drop the boring shirt and pants". You gasped at the thought of your wife running, wearing the skimpiest of the gym attire. You were amazed how much toned she has got ever since she is drinking that smoothie. "Will I see you at the trial class today?". You have never made it to a single gym session. But looks like today is going to be different. The trial class was in 1 hour so Emma went ahead.

You went to the cardio section, Emma's regular section but you couldn't locate her. After some searching you found her in the weightlifting area. Soon you realised that she is not alone. A really tall muscular guy was spotting her with the bench press. You decided to not approach. You notice Emma's face just inches from his crotch and his constantly gazing upon her big bust, perfectly shaped during the benchpress. You starting working out next to them, while Emma totally ignored you. During the workout Emma constantly maintained touch to his back, shoulders and flirted heavily. You could see that he was totally into her two. You were struggling to hide your boner in your tight gym leggings. Emma smiled as she could clearly see your approval in your pants.

Next you saw Emma saying something very softly to him. After which she left. You followed, to see her entering janitor room. The room is at the end of a hallway. Soon you could see the guy moving towards hallway. You acted cool and passed across him and when you turned back, you see him entering the room. You knew what is gonna happen. You almost ran towards the room and pressed your ear to the door.

"You are wet", you heard a male voice
"Because I wonder if your cock is as hard as your muscles"
"Well, we can solve that mystery for you",
"Lift me in the air and impale me!!", Emma shouted, as if teasing you at your inadequacy of lifting her. It didn't took much time to hear Emma's moans. Hell!, you can even hear him pounding your wife. "I have never been fucked like this before, keep fucking me...", "Take me from back, make me your bitch". Emma was very vocal. She knows that you are listening. He kept pounding her for 15 mins and she kept screaming, while you were stroking your penis, listening to your wife orgasmic multiple times behind that door.

You were at the edge when you saw janitor coming towards the room. As a good husband you ran to interrupt him. You don't want your wife to miss the best fuck of her life. Later you saw Emma going to the exit. You followed her only to see her entering in the stranger's car!!
