I’m not saying NO wives….. but consider the circumstances:
1.) Having 4 kids usually implies marriage
2.) Married women are notorious for ceasing the act of fellatio
3.) Even if fellatio is performed it’s rarely to completion as said fellator bc it transpires in the throws of sexual intercourse
4.) Having 4 kids would generally require considerable planning which would mean you’re planning on having kids which means dropping a load p in v style.
5.) Even if they were an accident, you’re engaging in p in v at the time. It’s not as if you were getting blown, she sneezed while you ejac’ed, and your load fell in her vagina
6.) Having 4 children implies likely a time frame of at least roughly 8 years of baby and pregnancy. Thats a lot of stress and time that takes away from anyone’s giving nature. Without the incentive of securing a mate because she’s already married, there’s no motivation for blowies.
