Is it normal to sometimes have sexual thoughts about our step cousin?

It's normal, common and even legal but in most places frowned upon...but cousins do sometimes hook up and even marry. We are attracted by people who look like us and have similar genetics. This is why twins seperated at birth sometimes find each other as adults and, not realizing they are related, fall in love. They feel some mysterious connection with each other and assume its true love. True story. As long as she is around the same age as you its fine in my opinion, not everyone is going to agree. Be careful, especially if you are underage, you could end up dealing with a really uncomfortable situation if she freaks out and tells her parents. Otherwise, i'd stay away from her and then look for someone just like her.

No blood relation.
Lay her down, spread her legs, and bang the lights out of her. Have fun with it!!!!

She is a step and not blood related , so bang away.
How old are you both ?

It's normal, when I was 12 I started light touching my cousin she was also 12. When we were both 16 we started having oral sex with each other. Still once in a while we will fool around, oral sex or hand job etc.

Go for it

step cousin = no cousin

go for it!!
