stepbro dick

The type of dick that is built nice and you wouldn’t mind fucking for the rest of your life. It’s not hardcore sex but it’s not soft either and you’ll be back for seconds. Ever seen a girl unsatisfied after a step to porn? Me either

Man she told me I got that stepbro dick
Dude, she’s definitely hitting you up again
