Okay, I'll start. I sleep on the 2nd floor of my house and on a hot summer evening I was asleep with the window open and heard an odd noise so I woke up.
It sounded like a cross between a couple rusty old barn doors creaking back and forth and a sea lion barking.
It was really loud and coming from the house next door so I sat up and looked out the window right into the ground floor bedroom of the house next door and with the curtain open I could see my neighbour boning his girlfriend. She had her knees bent and he was ramming her, up and down, up and down, his fbuttocks flexing with each shove as he slid his cock deep into her.
I know them both but I never knew she was so loud. She was groaning rhythmically in this deep masculine voice with each stroke as he heaved his hips at her, her legs high in the air Ahhhhh- Hnnnhhhh - aaannnggghhh - Hhhnnggggh -- Uggghhhh -- Hhnnngggh . Over and over again.
It was so loud his landlord came out on the porch of his second floor above the bedroom looking to see what was going on too.
