Bully who intimidates my step-nepheww cums inside me

My nepheww asks a friend of his to stay here at my house with me and my husband and I accept for just one night, and without any malice I accept. As the night goes on, he watches me take a shower, I feel like someone is watching me but I think it's my husband. My husband ends up getting a call from work and has to go out and doesn't know when he'll be back. I go to bed and when I wake up I get a fright when my nepheww's "friend" is next to me in bed and I ask: "What are you doing here?" And he tells me all about how he's been bullying my nepheww and if I want it to stop I'm going to have to give him a blowjob. I'm shocked at what's happening because it can't be true, but it really is and I don't want my nepheww to suffer so I give him a blowjob. And then he says he wants to fuck me and I say: "No way am I going to fuck someone who bullies my nepheww, my husband and I are trying to get pregnant!" And the bully says "well then I'll keep bullying you". And once again I realize that I have no choice but to fuck him, one problem is that there are no condoms available and I beg him not to cum in me. He agrees and fucks me like I've never been fucked before, at first I hate being there, but slowly it starts to feel so good, that I orgasm and feel so horny with him on top of me and he cums inside me while I beg him not to cum. I hear a noise and it's my husband coming, I ask him to get off me and he doesn't and my husband sees me with him inside me and the bully says "you're mine now" while my husband walks in shocked by the sight.
