Just Found Out My Cousin Was A Real Player

Last month for Spring break my family went to Florida to visit my Aunt, Uncle and cousin who own a small farm where the raise horses.
There was a movie playing at a drive in theater that I had really been wanting to see so my cousin said he would take me. There are no drive in theaters left where we live so I thought it would be neat.
My cousin is very handsome and a couple of years older than me but I had never considered anything romantic since we were cousins. However when he told me he had always had a crush on me I was flattered falling for it and ended up having sex with him.
A couple of weeks after we got back home I missed my period so I told my younger sister what had happened and I thought I was pregnant.
We haven’t told anyone yet but will need to soon before it’s too late to have abortions. We’re trying to decide if we should tell our parents who got us pregnant or make up stories to avoid family problems.
I was shocked when she told me he had f__ked her too when they went for a four-wheeler ride one day while we were there and she was late too. We took pregnancy test and sure enough he knocked both of us up.
