Next door neighbours have a 15 (poss 16) year old ds, who has his girlfriend over when his parents are out. His bedroom is right next door to ds' and I can blatantly hear them shagging. Which, y'know, is fine, but the girl is so loud! Not to mention the fact that i think the bed is up against the wall so we can all hear it banging.
In normal circumstances I would just go into another room, put some loud music on and wait for it to stop, but it always seems to be around ds' bedtime, and goes on for hours! Cue ds going, "What's that noise mama? I can't sleep, what's that noise?"
Not sure whether to say anything to neighbours, and if so, what?? Presumably he has his girlfriend over with their blessing (although possibly not shagging with their blessing, I don't know) so I can't exactly go round and say, "Oi, tell your son's girlfriend to Shut Up - and learn to fake her orgasms quietly!"
