Can a person marry the daughter of the woman whom he committed zina with?

My question is it permissible to have nikah with girl with whose mother I did zina? Now the story is that I did zina with a woman but the reality is that the woman did zina with me because I was 14 and she had three daughters at that time. Now my family did my nikah with her older daughter, she loves me and I love her and we happy for one another. I already did tawbah for what I did and I ask for forgiveness from Allah Almighty. Now we are in relationship already in nikah but I have a question sometimes in my mind, so is it allowed in Islam that her daughter be my lawful wife or I have to leave her? The zina one time we did almost 12 years passed, after that I never tried to do that with her mother nor her mother tried with me. Kindly answer me with details and references.
