Misc. Erotica My conservative Mom trapped in weird circumstances

[Innocent_Pervert]

Things had started to settle, the concept of One wife two husbands was finally digested by Both my dads and mom. Just as I thought everything was getting fine, a new problem arose. My Grandmother became to desperate for a child, according to her a marriage isn't complete until and unless a child is born. She started taunting my mother, Which made my mom very worrisome, She was doing everything a woman could. One night when she was with my dad sucking his cock, I heard their conversation :
Mom : Look , I need to talk
Dad : Yes dear, even I wanted to talk. U seem upset these days.
Mom : Its your mom. I am tired of hearing her Taunts.
Dad : Taunts??
Mom: I am doing my best yaar, to have a second child. Don't know whats wrong
Dad seemed confused, not knowing what to say
Mom : Actually its all your fault.
Dad : Mine?? (Confused a lil more)
Mom : Due to your blackmail, I have to marry again with your brother and now I am wife of two males. well logically since I am married my other hubby has ryt to plant his seed in me. Isn't that ryt?
Dad became upset, and started moving away from her.
Mom : hey come on I was just kidding. I love U and our son the most and that is never changing.
Dad seemed relieved still not knowing where this conversation is going.
Dad : I know nothing will change.
Mom : Will you love my second child as much as our first:
Dad (Shocked)
Mom : U have put me in an awkward situation.
Dad : U in awkward situation? Its me who is suffering the most.
Mom (Surprised) : Suffering? Isn't everything happening with your consent. Weren't you the one who convinced me to marry your brother. And now I have to bear his child all coz of you and you are suffering the most?
Dad Confused and feeling ashamed.
Mom : I have fucked you and bear a child.... Now my second husband wants same, how can Deny him the same privilege? Din't I make it clear earlier that once I marry him. U and he will be same for me. Due to second marriage, your brother has got equal right on my womb, how can I deny your brother from his marital right. At age of 43 , your brother sooner or later take every step to make me pregnant in this age.
Dad : How can you do this to me?
Mom : What have I even done? Look I want to make it clear. This is the last time before u fuck me, from now on I want to give my pussy to him so that He can breed me. I can't hear these taunts of your mom anymore.
Dad suddenly lost his erection. Mom visibly disappointed, Looks like you are not gonna utilize this last opportunity too. Anyway Pray that I get pregnant soon otherwise its only gonna get hard for u.
Mom Left.

I was shocked to see this change in mom's attitude. I knew Uncle was ensuring mom doesn't get pregnant by giving her medication and now until She gets pregnant she wont let my dad have vaginal sex with her. If I tell this to Uncle he surely will use this info, to trouble my dad even more, and If I don't tell me, in some days he will loose control and get her pregnant. What should I do?
