We have recently shifted to Delhi in a very small house having two small bed rooms. I have my elder brother, my mom and pa in my family. My mom and pa are sleeping in one bedroom and my brother and myself sleeping in a single bed in another room. One day when I was preparing for my test in the night. I noticed erected penis of my brother which was coming out from the dhoti he used to wear. His penis was so large and attractive I could not stop myself touching it. I was so fascinated with it. I took his penis in my vagina. Since then we are daily having sex with each other without the knowledge of our parents. But love to have sex with him, but worried about thinking my future life when I would get married. You are requested to please advise what to do. Will my future husband able to find out the truth. I have no regret as far as our relationship is concerned the only fear is my marriage life. Please advice.

He may come to know from the way you respond during the sexual act with him as experienced female would respond differently than novice one, provided he is smart enough and also experienced.
