Almost caught having sex😂🤦‍♀️

So my boyfriend stayed over the other night and it was about 1 in the morning and we thought everyone was sleeping so we decided to have sex and it was about 2 minutes in when i hear a knock and my door swings open and ive never seen someone roll so fast😂 luckily it was dark and turns out my mum wanted a new puppy pad to put down😂 but we didnt get caught thankfully... has anyone else got caught or nearly got caught?
