STIEFBRO IS A PAIN IN THE ARSE! STORM-FREE SHAMELESSLY EXPLOITED!!!

Mummy and stepdaddy are out shopping and I'm fully absorbed in my work when my stepbro bursts in and wants to start another conversation. Annoying as always. But I have to hand it to him, he's got a hot cock, I've tested it out before. And now he probably wants to show off his cock again. But phew... I don't really know, I'm really scared that it's going to come out! It's really hard to resist...
