50 Shades Of Steve Rogers

This is kinda SMUT, kinda not, like for reals, and yes its about Steve Rogers, but chillax the "sorta" (I say sorta, because people are bitching) reader and Steve are married, happily enjoying each others company. The reader, though, has denied a certain part of her libido because Steve is old fashioned and she's afraid what Steve will think when he finds out that his "strong" wife likes it rough, likes to submit and needs it. Can Steve put aside his old fashioned mentality and do that for her? And it's not an Xreader since I gave the reader characteristics, but I'm not changing them even if people keep complaining, so you've been warned. If you don't like the idea of an 'xreader' with an already somewhat description, please don't read, and if you do read, don't waste my time with your 'it's not an Xreader' comments. Also there is a Supernatural connection, but haven't decided yet if I'm going to make it a full blown crossover.
