Your idea is so Erotic..Make your mom pregnant bro.
But, I think it not necessary, because she is at her middle age, and at this age it is little difficult to give birth a new born..
And in this long period she can't enjoy her sexual life and after the delivery she also get some extra responsibility towards her baby...
All these Extra burden ruins her Fucking sex with BBCs ....
She should enjoy BBC and go to tour with them along with her son..
But I think Write end this story here...
So I only can Fantasies my fantasy in my mind...
Uffff
That was one of my favorite story...
