It probably implies they are specially made condoms when an alpha is in rut and is popping knots left and right. Lol I imagine they are condoms that could expand at the base alphas have to buy for their size and knot size.
How much semen can that one condom hold?
By my estimates of the stupid amount of yaoi I read and over inflating cause it's funny and alphas usually are described to have long ejaculations up to half an hour. Maybe like idk 4 oz of fluid, which could be imagined as a quarter of a typical water bottle.
You ever filled a condom up with water? They're very elastic and hold a lot
Girl, someone even blew the condom like a balloon for fun, so I am sure it can hold more than you think...
But that's if there was no friction from being used, right? Besides, condoms aren't 100% either. There's still a chance of pregnancy, and with their body types, the possibility is higher?
That is when you don't wear exact size... :3 also since this is a fictional story, they would probably have special condoms for rut...
Cause they'd be coming and stuck for a long period of time. You sure the condom isn't gonna break?
