a little secret

my partner doesn't know this about me, but i secretly love the idea of age play. tonight we were alone and drinking wine, so i brought up some mild roleplay ideas. surprisingly she was open to it, so we ended up pretending to be teacher and student. i acted as the strict professor... while she played a curious college kid looking for extra credit. it was all very tame, but still made my heart race! not sure if this is normal or just my weird secret fantasy life....
