About 1 and a half hours ago me and my wife decided to have sex, on the couch. Our children were all engrossed in homework and all, so we closed the doors and had some fun. Then just 5 mins ago as we were relaxing on the couch with a sheet, I hear 10 year old come down, and so panicking we slid under the sofa, with our clothes in the bedroom. She is now watching tv, and we are under the couch, and it's one of those older models where there is only one opening and the rest is walled in. Please help!

UPDATE FOR UNHELPFUL PEOPLE MORE CURIOUS ABOUT THE COUCH:

We got out after she went up after 30 mins.
