"Honey, my friend J.R. had a little too much to drink so I gave him a lift and I'm letting him crash here!" She shouted up the stairs after coming into the house. That was bullshit because if that was the case, she'd had driven him to HIS place. And, you know, I saw that J.R. was the one driving. I didn't reply.
"Shhh, Carol, he's probably asleep, you goofball." I heard J.R. mutter.
After what I can only imagine was some more playful groping and giggling, I heard my mom's bedroom door slam. I never had much luck with the girls, but of course I always considered myself as having a normal sexuality, and yet I could not begin to comprehend why my dick got so hard and so fast at the realization that my mom is about to get plowed after a first date a few yards away from me. My heart was pounding so hard I could feel it in my face. I was going crazy. I waited a few minutes after that door shut, opened my door slowly, and began slowly, stealthily crawling my way downstairs, across the house, and towards my mom's bedroom door, being careful not to cause any creaking sounds. I got quite good at that from the many times I snuck out of the house in the middle of the night to hang out with friends.
I wouldn't dare try to open that door. As long as I've lived there, I've always known it to be the creakiest door in the house. You could probably breathe on it and it would creak. I heard the sound of bodies rolling around her bed, the rustling of the sheets. I could hear my mom's heavy breathing. Then I heard the rattling of the bed frame and the sound of flesh slapping together. Then came her moans. I was rubbing myself outside her door. My cock was so engorged, it hurt. But I couldn't stop myself. My mom's moans turned to deep, almost animalistic grunts as the rattling of the bed intensified and became accompanied by a very loud, repetitive knocking sound. My mom was getting fucked so hard, the big heavy slab of wood that is the headboard was being relentlessly slammed into the wall like it was nothing.
I crept away from the door and into the living room, which shares a wall with my mom's bedroom, and is also the wall against which that bed is positioned. I found the spot on my side of that wall where the knocking sound was loudest. I pressed my ear against it. Holy shit, I could feel the wall bump every time the headboard hit it. Her grunts and moans were so distinct, I could tell her face was mere inches from my ear with only some drywall in between, while this J.R. guy was pounding her from behind. I took my ear off the wall, pressed my whole back against the wall, pulled down my pants and started furiously jacking off to the feeling of the wall thumping and vibrating from the hard fuck my mom was receiving. I knew it was fucked up but nothing could have turned me on more in that moment, not internet porn, not a nude photo of my biggest crush from high school, nothing.
I finished in a matter of seconds, a personal record for me by far. Of course, they weren't done yet. I returned to the bedroom door, sat down, and listened to them for another 20 or 30 minutes. Granted, he wasn't banging her hard for the whole duration, but my mom made it pretty clear she was having the time of her life by how, uh... "vocal" she was in there.
