I can only see the living ,kitchen and they do it all over both.Nothing quick about it. The quickest I have seen was a bj on the couch on the run to go somewhere.The average sex duration in studies is 5.4 minutes . Judging by what goes on on RLC, that seems to be true except for N+B.Taking phone use into account on RLC and them stopping to text in the middle of sex, I'd say the time for sex is down to a minute and a half
