I'm looking for a MxF manga and I can only remember a little bit about the plot

I /think/ it had something to do with the F wishing for her crush to like her back?? And the entire time she's worried cause she believes that the "magic" worked??

This may not be from the same manga but I'm looking for this one too: there was an "extras" scene at the end where they asked if her first time hurt and she explains that no cause the M fingered her for 10 minutes and then ate her out for 30 or something???? ┗( T﹏T )┛
