Step Brother jokes

I was tickling my step brother's balls, and then it hit me: why is he laughing?

When I say, "Daddy," my stepbrother raises his head.

What did the stepbrother and stepsister do together?

Oof, mitosis!

Brian has a crush on a cute girl, Sally, from school, so he goes and tells his dad about her, and he says, "Sorry, son, you can't like her; she is your sister." So Brian is okay with it, and he starts to like another girl, Madison, and he goes up to his dad and says, "I have a crush on this girl, Madison," and again the dad goes, "Oh, sorry, son, you can't like any girl in school; they are all your sisters." So he goes crying to his mom and says, "Dad said I can't like any girl because they are all my sisters," and the mom goes, "Oh, it's okay; you can like any girl you want because he is not your dad."

My sister's boyfriend is mad at me because I fucked his girl.

A brother and a sister always got into fights. One day the brother tells the sister, "You're adopted!" The sister yells back, "At least they wanted me!"

Jack and Jill went up the hill to celebrate their marriage.

Nine months later, they happily had some use for their baby carriage.

Two years later, they went up again, then their daughter had a brother.

But one little secret that no one knew was that Jack and Jill share a mother.

Billy: "I'm so used to having you in bed with me, I don't know if I'm ready for this long-distance relationship."

Sally: "Ohh, don't worry brother, I'll just be right down the hall..."
