finally did it with my sister-in-law

so i have this thing for my sister in law she is like 30ish and married to my bro but we have been flirting a lot lately. we both know its not right but damn the chemistry between us just feels so electric you know? one night after everyone else went to bed we were both feeling adventurous and decided what the hell why not. i went over to her room under the guise of needing help with something then closed the door behind me. it was all very quick and dirty in the living room but honestly it felt like a dam broke or something inside me. never thought id be into a sister-in-law situation but here we are and its kinda addicting. i hope my bro doesnt find out cuz well yknow hes family but damn she's got something special going on
