They're step sisters. Or step twins? Same father, but their mothers are twins to each other.

It would be what happened if MC had a kid with Felicity and Emma each.
I looked it up and apparently, society would consider them half-sisters, but also cousins.

Genetically they would be also be considered fraternal twins, as they would be the children from the same mother, even if they were born some time apart.

Happy Halloween! Have you all been good little Boils, Ghouls and Goblins? Perhaps on the morrow's eve there shall be a treat!

(uploading images to the forums seems to be wonky right now, hence imgur. This is just a teaser of Android (Annie) for some Halloween/Costume Party Pinups. Only the one image for now. If uploading is still broke tomorrow I'll use a zip...if that works...lol. All the main girls will be there though! Time to guess the costumes of the girls yet to be seen! Hint, very much in the realm of the Batelf comic!)

Does this mean we'll get more content/ lewd scenes with the college girls? It would be kinda a waste of good models if we dont get to do stuffs with them (I really enjoyed the trip with Vanessa. Really hoping to get more scenes with them.

if that makes them fraternal twins then all siblings are fraternal twins. So, no, they aren’t genetically fraternal twins.

Identical twins share the same DNA. Runey said the girls' mothers were identical twins, impregnated by the same man. Its still two batches of the same genetic material being combined. So they would be genetic fraternal twins.

Genetic fraternal twins aren't a thing. Fraternal twins are just ordinary siblings that were carried simultaneously in the same womb instead of sequentially. Legally, they are half sisters and cousins, and genetically they are full siblings, but they aren't twins in any sense.

this has been covered in another comment. But I have a brother and a sister. Both the father and the mother of these people share the exact same dna as my parents (because they’re my parents) this doesn’t make them fraternal twins. That’s a label we apply to people that shared the same womb at the same time but didn’t split from the same egg.

Yeah, they're not twins, they're half siblings. But genetically speaking they share more DNA than the average sibling due to their genetic history. It's sort of like the royal family in one way, even far cousins are considered closer due to all the incest in the past. Obviously no incest here, they just happen to be closer than you might expect. Which also plays a part in their personalities!

is there something beyond their parents being twins and having the same father? Were the father and mothers related?

they don’t share more dna than average sisters if their father isn’t related to the mothers. All siblings’ mothers share identical dna, that’s what makes them siblings (along with having the same father).

I don't know about you, but I haven't knocked up twin sisters seemingly on the same day yet. I guess I should add that to the bucket list?

You're still not understanding what I'm saying, I think we've been over this on discord. They're half sisters, yes. But they share more DNA in common than you would expect, because their mothers are twins, and they were conceived on the same day. I don't think repeating that again will help, but I dunno what to try.

I mean, I have a half sibling. They don't look much like me at all because their mother was not my mother, or like my mother genetically.

I'm not trying to involve myself in this argument, I'm just adding context.

I fully understand what you’re saying. I don’t think you’re listening to me.

Legally they are half sisters and cousins. Genetically they’re more than that because their mothers are twins, but the “more than that” is just full sisters, not twins.

take away the time constraint of being concieved on the same day they aren’t any more genetically similar than two children born to the same two people.

This is pretty much what I just said in my other comment. Their mothers are twins, not just siblings. So... yeah, more than you would expect.

...You know I've been agreeing with you, right? At least your first comment in this discussion.
