Whenever I get ready in the bathroom in the morning, I have a bad feeling. Something is wrong. But apart from me and my mum's boyfriend, there's no one at home. It can't really be! Until this morning!!! I'm getting ready for school and have just put on my thong and bra when I hear soft moaning from behind the door!!! I turn round and catch my stepdaddy secretly wanking!!! OMG!!!! The situation was extremely uncomfortable, but I see his cock for the first time and I have to say, it's really big and nice... And if it's already hard, why shouldn't I treat myself to it, especially when we're home alone!
