hello friends

I am a 24 year old girl. I had sex with my cousin brother who is only a high school student. He saw me masturbating in my bed, and took photos and showed then to me. He told me that he wants to have sex with me. I was black mailed. Forcefully I had sex with him.

We had sex for 40-50 minutes. Firstly we did oral sex. he sucked my breast and later my ass and pussy. He had intercourse for 15 minutes. He suddenly stopped fucking as if he ejaculated, but I never saw semen in his penis. This happend after 4 days from my period.

Now I am afraid of pregnancy.
