Stepfather catches me changing and fucks me through

So my stepfather always catches me in the most embarrassing situations. I'm just getting changed when the door opens and my stepfather storms in. He looks at me, visibly surprised. But I can already see that there's a bulge in his trousers. I can't leave it like that. And so I take out his thick cock and start to spoil him with a deepthroat. What a big piece, I almost can't get it all the way into my mouth. But that's not enough for him, of course, so he turns me round and fucks me deep doggystyle. But he doesn't last long and I turn round to the missionary position. But that's really too much for him with my young, tight pussy and he sprays his cumshot on my stomach and on my big tits. Do you have such a sweet secret?
