I am married women slept with other women. I am confused.

I am 32 yr, old married women. Last month I went for an office trip along with my colleague(another married woman) to another city. We went to the hotel after work. At night time while watching TV she touched me. I liked so I didn’t stop her. Finally, she undressed me and we ended up having sex.

I enjoyed with her. I had never thought of this before. Even it was she who initiated. I know it’s my mistake that I let her do it. I love my hubby and my kid too much. I have a healthy sexual life with my hubby. But now I am confused. Because she wants me to continue this. She told me it just for a change and no harm.

What should I do?
