The act of engaging in sexual activity with an immediate family member acquired through marriage, i.e., step-brother, step-mother, etc. Not to be confused with incest, which would be performed with a blood relative and includes family members outside of siblings, parents, and children (e.g., uncles, close cousins). A prominent theme in the adult entertainment industry, it is markedly less prevalent in the real world. Step-incest is typically frowned upon in polite society, although cases do exist wherein couples can be "grandfathered out," so to speak, if they were doin' the deed before their parents got together.
- I'm so tired of watching step-incest, bro. Don't you have any videos of midgets, or something with circus animals? Maybe both?
- Well, in this one the chick's step-dad IS a midget.. And I've got "My Step-brother Tames Lions, But Can He Tame This Pussy?"

Get the step-incestmug. 
An incest Friendgroup is when normally a larger Friendgroup mixed with both boys and girls and they date each other. The dating span could be weeks to months to years. But they always break up and they both date someone else in their Friendgroup while remaining close friends with their ex's.
Hannah used to date Troy and Troy used to date Madison but now Hannah is dating John and Madison is dating Hunter and Troy is now dating Ava.
Yet they all remain close friends regardless of having awful breakups and they act as if they never dated, passing each other around like blunts and knowing what each other taste like.
