Step Sister jokes

My stepsister is a big titty goth. Should I tap that?

My dad came out of my step-sister's room as I came out of my step-mum's room.

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."

What's the difference between your girlfriend and sister? Nothing if you're from Alabama.

Screw sister from a mister or brother from another mother. We besties from another testie.

I told my sister I was into incest. She took it really hard. 😉😏

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