Caught Buttfucking Your Own Step-Daughter

[this was a custom request] your cute, little step-daughter calls you into her bedroom one day, telling you that she wants to tell you something important. she asks if step-mummy is around and seems very pleased when you say she's busy in the other room and won't interrupt the two of you. your step-daughter begins to reveal that she's a dirty little cumwhore - you're taken aback and tell her that it's inappropriate but she dismisses you, telling you that she's simply being open with her step-father. despite this, you feel that she's beginning to tease you - opening her legs and asking if step-mummy ever fucks you anymore. she can tell that you're turned on and slides off her panties, asking you to sniff them because she's been wearing them in her sweaty arse all day at school. they smell divine and you're horrified to feel yourself getting hard. she bends over in front of you and shows off her perfect arse and pussy, telling you to sniff straight from the source. she begins to mock you for getting hard over your own step-daughter and you feel obligated to teach her a lesson by pushing your hard cock into her wet pussy. she feels amazing and so wet for you. but you're stunned when she tells you that actually her favourite thing is anal and guides your cock into her arsehole. you fuck her hard in the arse while she tells you that she must feel much tighter than step-mummy's pussy ever has and laughs that step-mummy has probably never let you do this to her. that's when the worst happens - your wife walks into the room. you stop in absolute dismay but your step-daughter encourages you to continue and simply greets her step-mother with a little smile. she starts to mock your wife, telling her to watch while her husband fucks his own step-daughter's tight arse because she's not seen to you in such a long time. she lies on her back with her legs spread and guides you back into her arsehole. the whole time she laughs at her step-mother, encouraging her to watch and revealing what a dirty pervert you are and have always been - how much you like to sniff dirty panties and fuck small girl's arseholes. when she begs you to cum inside her tight butthole, you can't resist. you splash a huge load of cum inside your little step-daughter and let your cock soften inside her. as she pulls your out, she tells her step-mother that she must've always known that you would cheat on her eventually with a younger woman - but i bet she never expected it to be her own innocent little step-daughter.
