Review Detail of 100Fahrenheit in My Self-Insert Stash

Dude thanks a bunch btw looking for recommendations on MCU (or Marvel) Either SI or Oc or X-over as an MC is fine, as long as they were not in canon. Btw no M/M (male/male relationship), no OOC (out of character) and at least 40k+. P.S. haven’t seen much of black widow as a pairing with MC (and still be a story not a plotless smut)
