Yeah it's slightly ominous because you're looking at it from a parents perspective but hey, atleast it's not incestuous...cringey though. Hopefully they understand contraception and safety (sorry to even say that).

The lost episode of the Brady bunch when Greg yelled MARSHA MARSHA MARSHA!

I messed around with my step brothers when I was younger too. Don't worry about it.

time to sit them down and have a talk with them about playing "doctor". don't be mad at them, if they are young teenagers, it is normal to be curious about the others body parts and what they look like. if they have "fallen for each other", don't tell them they are "going to hell" or some other BS. when you talk to them, listen to what they say. step siblings falling for each other is not that uncommon.

Oh no that's as bad as blood related lol

Teenagers???

I guess this is what step bro was doing

Well, as long as they are aware and stuff, I agree it's weird, but not terrible - remember that there's an entire genre within the porn industry based on this exact scenario😜 Best of luck for your family!

At least they're doing it at home instead of out with strangers.

Should've just paid more attention in sex ed class
