It's 1940, Brooklyn New York, Peggy's sister Riley comes to spend the summer with her. Riley is a young writer, well hopefully writer. She is in a time where sexism is real bad, the 24 year old woman finds herself in a fling with her sister's, boyfriend's best friend.Or more know as Bucky Barnes the famous Captain America's best friend. Peggy was dating Steve, of course. Not everyone is the biggest fan of their relationship, sneaking around is still an option?right? • DISCLAIMER • I do no own any of the characters like Steve Rogers, Peggy Carter, Bucky Barnes, Howard Stark etc- those belong to the MCU and the MCU only <3 TW: swearing, sexism, and smut (eventually), smoking, and drinking, if any more I will let you know before!!
