Stepparents suspect nothing! Fucked in senior WG!!!

Because I have not endured it at home, with my stepbrother and stepdaddy, I am for one night to an older gentleman to spend the night with him. The next morning I'm standing in the kitchen, there comes and makes me just so on. Fasst me on the ass and said that I can move in right away. Well horny I've become anyway and then we fucked properly. First he did not come for ages and then just injected into me!!! Should I move into the WG, what do you think?
