Is it normal to have a secret lesbian relationship?

me and my friend (well call her Mary) are haveing a secret lesbian relationship. it started 2 weeks ago when we were at her house and were watching a movie when a lesbian scene came on and I got wet. I could tell she was horny because she was breathing hard. so anyway the movie ended and we were having a pillow fight which changed to a tickle fight when she fell on the bed and I began to tickle her and vice versa. soon enough tickling turn into touching. she was so gentle it took all I could do not to kiss her. somehow my hand made it's way to her vagina and she kissed me, passionately, fastly, it was all very sexy. after kissing her I went under the blanket and started to lick her thighs slowly and made my way inside of her giving her oral and she did the same. were 69ing it's was so hot she started to play with my hair and it excited me extremely. I started fingering her and she bit me on my neck blah blah blah we ended up screwing.

so is it normal to continue this relationship? we have discovered were both lesbians and would never be satisfied with men.
