You (my bf) tell me to look after your old step-father and I obey. I start cleaning his room dressed sexy, but meanwhile I vent about my bf’s infertility and impotence and that he has a small, limp dick and how much I want to be pregnant but unfortunately we can't do that, no matter what. I feel like my womb is about to fall apart and I throw all my emotions towards grandpa. Then I get ready to give him a bath and I notice his huge bulge through his pants and I'm amazed. I undress him completely and notice how big and erect his cock is and how swollen his balls are. I am sure that if grandpa got me pregnant my bf would understand, after all, it's for us to have a family. I start fucking at first I am alone with grandpa, then you come and see us fucking, i tell you some excuses, I tell you I do it for the family, then I brutally humiliate you, make you look at grandpa's cock, he is so old that he needs to be washed but he has a huge and fertile cock. I use much small penis humiliation, limp humiliation, old-young humiliation, mock you, talk to grandpa and mock and humiliate you together. I make fun of your stupid goon face. I mock you and call you ugly loser fucktard. I tell you that you are such a stupid, addict to see me fuck grandpa’s huge cock and we are making fun of your loser stupid face that you have while stroking. I say that you are a stupid impotent chronic masturbator who likes to be mocked and being laughed at by me and your grandpa. I imitate me while yiu masturbate and I make fun of you together with step-father, i actually imitate the gesture of masturbation and your excited stupid face. I tell you that you love to be mocked by us two. I tell you that you are a stupid ugly loser with a mock fetish, the way you look when you stroke your small. I say: "You see the ridiculous faces I'm making? That's literally you loser. I am your mirror. This is exactly what you look like and it's fucking hilarious! LOL! You do this every fucking day, don't you? Of course, this is who you are loser, a chronic masturbating freak! This is your fucking reality. This is what you deserve, you deserve to be mocked, you need to be mocked bu me and grandpa, addicted to see me fuck a huge old cock" Fuck you loser!
