POV: i am your sister who is recently widowed. We are returning to your home after the funeral and i thank you and your wife for all the support. you even offer to let me move in with you until i get settled again and i excitedly accept.  i talk about how excited i am for a fresh start and make sure that you know that i will pull my own weight around the house. next scene: i grab my pjs and am going to the bathroom before i get ready for bed and accidentally walk in on you as you are in the shower. i quickly apologize and retreat from the room embarrassed but i then crack the door back open and secretly watch for a few moments.  next scene: i return to my room embarrassed with what happened but turned on by what i saw. i am just horny because i am lonely and acknowledge that this is wrong.  i sit on the bed and try to shake myself back to reality but eventually remove my dress, lay back, reveal my breasts, pull my panties to the side, and play with myself while feeling guilty for thinking about you like that and not understanding why i am so turned on by your my brother. i shake myself out of it before i cum and then get changed into frumpy pj's for bed.
