You told Mommy you'll be out all day but after a change of plans you end up home. You hear her upstairs so you go up but then you hear some off sounds. Is that moaning? What is she doing in there?! You wait and listen at the door and now you know, Mommy is wanking in there. You can't resist and burst in. Mommy is pissed you didnt knock. She's annoyed you've caught her and instead of telling you off she just says get out she's busy and doesn't plan to stop. You start undoing your belt and Mommy asks what do you think you are doing! You tell her to carry on and you want to watch. Mommy is curious and really horny so she reluctantly agrees but tells you there will be no touching, only watching each other. Mommy carries on fucking her pussy and rubbing herself and tells you to take your cock out and show her how you cum. It gets hot and intense, watching each other non stop, knowing you can't touch. When Mommy is about to cum she breaks the rules and begs you to cum ON her pussy. She wants to feel your hot cum marking her. Mommy tells you to forget to knock from now on.
