I was traveling on business recently in Europe and was staying overnight in a smaller hotel, not unlike an American bed and breakfast. I discovered the walls were paper thin one night when awakened by the sounds of voices laughing and talking in the adjoining room. I rolled over to try to return to sleep when I could hear the bed in the next room begin shaking. Becoming more awake I realized I was overhearing the couple in the adjoining having sex. Horn dog that I am, I perked up and put my ear closer to wall, figuring I'd enjoy the show.
I could hear a deep male voice complimenting various body parts of his lover, following by kissing and slurping sounds. As the slurping continued and became steady, I could hear the female voice moaning. I admit it was making me hard.
Not having the visual stimulation, I had to imagine what the scene I was hearing looked like. I envisioned her laying on her back, legs spread, with him laying or kneeling between her legs providing oral stimulation by all of the slurping sounds I was hearing.
My growing cock slipped out of the fly of my boxers and I began pulling and stroking it to its full hardness.
After several high pitched moans, I could hear the bodies moving about. With the voices having gotten louder, I presumed she had now gotten on all fours facing the headboard with him mounting her from behind so that both faces - voices - were pointing right at the wall at which I was listening.
I could hear the steady creaks of the mattress and box spring indicating his slow but steady penetration. She was moaning with pleasure and telling him to give it all to her; it was followed which a gasp which I presumed meant he pushed further into her wetness. I could hear the steady squishing sounds of their sex along with the bouncing mattress.
I took off my boxers and pumped my hardon, trying to match their rhythm. Of course, I was envisioning that if the wall weren't there, she'd be facing me and reach up to stroke my hardon while her lover pumped her from behind.
She yelled her enjoyment and told him to do it faster...harder...faster... He was obviously riding her well as the headboard began pounding against the wall, joining the squishing and bouncing sounds of their passion.
This went on for a good twenty minutes; I didn't think I'd last that long without busting my nut. The pace of their sex increased and I heard him say he was going to cum followed by deep grunts. Not wanting to be left out, I released my own load all over my headboard and pillow. It was an awesome orgasm and a hot jerk-off session that I hoped would happen again before I left. I did one other time. Now I listen intently whenever I'm staying in a hotel to see what I can hear.
