I wonder if my son hears us.
I can remember as a pre-teen when I lived with foster parents. They were in their forties and somewhat quiet and nice people. Except at night.
I never paid attention to noises at night until I heard some whimpering sounds one particular evening. I got up to investigate and to my young naive horror I saw my foster dad on top of my foster mom. Yes they were 'doing the nasty'. He was going up and down quickly. His fat butt cheeks jiggling. Her legs were in the air and she was making strange sounds.
The light was dim but just enough for me to see their naked shadows. I returned to my room because I didn't want to get caught watching. Almost evey weekend I would lay in my bed and hear the bedsprings squeaking and the low tone squeals and moans. Once in a while I could hear my foster mom utter a curse word, 'fuck me darling' or 'oh shit, yes baby'. Her normal vocabulary was 'darn it'. I spent about a year with them and moved to another house. To make a long story short I discovered masturbation and late at night in my bed I could still remember and hear the sounds from my first foster parents. My new parents were more discreet but I imagined about how they did sex. I still use those memories to gain an orgasm.
