Your brother is showing you the taboo porn he found last night and the two of you are jerking off, hard cocks in hand when mommy walks in. She’s shocked and apologises for interrupting, before realising that the woman in the porno is moaning “fuck mommy”. She tells you to turn it off and explains that watching porn is fine but this taboo stuff is just wrong. She asks you why you were watching it and your brother explains that it’s exactly because it’s so wrong that it’s so hot. In fact, that’s why both your cocks have only gotten harder since mommy came in and caught you. That, plus the fact that mommy’s tits always turn him on. You agree. That’s when mommy lets you in on a little secret – she watches that kind of porn too and seeing her two big boys with their big cocks out has had her pussy wet ever since she entered the room! She’s never seen both of you like this before and decides that seeing as a line has clearly already been crossed, it wouldn’t hurt to cross it a little further would it?
