Hey thanks for coming over and putting together that bookshelf! I mean isn't that what brother-in-laws are for? oh you have something for me? what's this? you ordered keds for your wife and they were the wrong size so you're giving them to me? how thoughtful, I usually don't wear keds but let me try them on. Wow they fit so well! what do you think? wait, what is that? is that a bulge in your pants? are you hard? OMG, this is so inappropriate you are my brother-in-law. Well look, since you put together my bookshelf I guess I do owe you. Ok, I will let you jerk off to me in my keds but this has to be our little secret. No one can ever know. Go ahead, take out your cock and start stroking. I had no idea you had a keds kink!
