My stepfather is a pig, he always fucks my ass bareback

I always wanted to have a father figure, but i never imagined that i would have to put his ass on it. he is a quite dominant and authoritarian mature man, he is not my real father but as if he were. the only difference from other parents is that he and i fuck together. i know it is not fair for my mother, who is madly in love with him, but apparently i put more. it is considered bisexual, but i think that the "bi" is rather invented, because you just have to see how crazy he gets when he fucks my ass. first he takes his cock out, i am delighted to give him a blowjob. it has it just as i like it, big and hard. but oral sex is not enough for him, so he always bends me in the kitchen and bare-dicks his huge cock into me. we could go to the room or any other place, but he says that it makes it hotter to do it there, morbid thing. i always cum first, the truth is that having him inside makes me so horny that i can't help it. there is only one other thing that makes me even more, and that is to feel how it runs inside my mouth. so once i cum i like to get it out of my ass and even with my taste eat all the member until it feels like it empties in my mouth hitting my palate with his semen.
