It's not even the number of kids but the number of dicks.
You see, young, pure, virginal teenage girls have a discrete, slight protrusion of labia, often nothing more than a slit.
After a plethora of parading penises proudly pounding her pudendum, the labia will stretch to disgusting proportions and the whore's cunt will now resemble roast beef. Hence, "roastie".
Everyone knows a vagina stretches in direct proportion to the number of penises that have been inside it.
>but muh babyhead
At first it makes sense that a woman who's pushed a fucking baby's head through the love canal would be stretchier than the 16yo hs whore who's already banged the entire football team... but ever notice how it's usually just not the case?
Mother of 3, married to the same man for 20 years, when she finally gets divorced and you're the first guy she's fucked since her husband, has the kaganal strength of a steel trap? That's because she's only had one penis.
Yes, vaginal birth causes TEMPORARY stretching (and sometimes tearing, which will heel) but if she's only ever had one penis in her, the temporary stretch will return her vag to pre-baby levels.
This is due to the enzymatic interactions between her skin and her husband's skin.
But what happens when a femoid - babies or no babies - takes multiple cocks? The enzymatic reactions between her and EACH partner will PERMANENTLY stretch and expand the vaginal walls AND the inner and outer labia.
Condoms will NOT prevent this, as there is always skin contact at the groin area. It is the reaction between the male's skin and her own (sometimes via her own vaginal fluids) that causes the stretching to become permanent.
So, when my friend once said, "I fucked this girl who had 2 kids, but she was tighter than this one other girl I fucked," I explained all this to him and it made perfect sense.
Okay, so now you know why there are even size queens in the first place.
You're fucking welcome.
