While out in the ministry one day this couple saw us approach their house and thought it would be funny if they acted like they were having sex, (loudly) as we knocked on the door. I was going to wait til they were done & knock again but the older witness lady with me grabbed my arm to leave. I told her, you know they were just acting don't you? She said had she known that she would have kept knocking, I said come on, NOBODY is that loud. Then we laughed. It was just a white-trash thing to do but I am still going back.
MY girlfriend get really loud sometimes, after I give 6 or 7 orgasms(she is very orasmic) I don't know if your a male or female but I think you may have misjudged these as white trash worldling indulging in sin sinful loose conduct when in actuality they were perfectly within there right to have great sex in there own home without having any resposiblity to answer the door you were knocking on.
