Marrying Shy Girl from next door

I 31 moved into my current home in October after completing my last contract overseas. No plans on staying very long as I prefer life overseas to the shambles presently happening here. I've several things to finalize here and expect to finish by March next year and would move fulltime overseas. I was a late child no siblings, and my parents and grandparents are all deceased and no real close relatives left as far as I know. My closest neighbors are two women mother 45 and daughter 26 only child, the mother welcomed me to the building, her daughter was with her but very quiet and timid always stands back and says nothing. But as time passed, she got more familiar with me and less timid. She started saying hello on seeing me. I'm doing very well with the mother, and she regularly joins me in my bed. They both know of my plans to move back overseas, and the mother is quite interested in joining me. The daughter hadn't said anything. Till last Monday when I finally bedded her, with her mother helping me to bed her daughter. Like me they have very little in the way of relatives left here and none they would miss when they leave with me. No positive future job wise here for them, they work to survive and it's getting harder as each week passes. Just getting by isn't a future, once everything is finalized here for me, I will be leaving with them both. Planning on marrying the daughter Sunday December 7th, quick marriage is so her passport will show us as married. It will be their first passports as they haven't more than two states away in their whole lives. They also moved in with me last Friday as their rent was increased again, they have a monthly lease, the building owner prefers it that way, it enables them to increase rents regularly. I've a 6months lease, so no rent increases for me unless I've to extend. But have no wish to do so, might even be able to leave earlier depending on property sales and other inheritance related issues being finalized. I'm quite happy with my wife to be, she does as I want and doesn't mind me fucking her mother either. I'm hoping to get my wife pregnant asap, her mother can't have any more children due major miscarriage when she lost her second child after a car accident that took her husband also. So, my wife is looking forward to being my wife and mother to our children. Perfect arrangement having a wife and willing fuckable mother-in-law.
