FIL Fills Me Every Week.

Got married mid summer two years ago and absolutely love being part of my wifes family, as I don't have any on my side.
The night before we got married I finally gave up my rear to the man, who for nine months, had been having me suck him off.
He'd call by our flat almost every morning during those nine months and usually within ten minutes (He likes me to make him a cup of coffee) he'd be sliding his large cock over my tongue.
And the reason I was sucking his gorgeous dick pretty much every day, is he'd found out I used to give two of my college tutors head.
The first time he had me suck him, my fiancée has only just left for work.
He didn't even ask per say, he just took his cock out in my kitchen and told me to drain his balls.
I did swallowing his warm sticky cum after at least twenty minutes of blowing him. Only afterwards did he let me know he knew about the college tutors.
I knew he wanted to fuck me, but he said he'd wait until I was part of the family.
However the night before I tied the knot with his daughter, he visited the new house he'd bought his daughter and I as a wedding present.
Telling me he wanted me to be a real part of the family, with his daughter staying at his and my future mother in laws house that night, he had me get naked, suck his cock and then he fucked me every which way you can for over an hour.
Half way through the sex, he took a phone call, stopping from fucking me, but had me suck his cock as he spoke openly to my fiancées mum about him welcoming me properly into the family, as he put it.
He'd put his phone on speaker and I heard my future mother in law say as I continued to suck his cock "Make sure he can walk tomorrow, don't fuck him too much". I could hear her giggling along with my future wife before the call ended.
He stayed the night and we fucked twice more before he drove me to the wedding ceremony venue with my arsehole full of his spunk.
Now two years on my father in law visits even sometimes if his daughter is home, two to three times a week, and fucks me.
My marriage to his daughter isn't the conventional marriage, yet it definitely works for us. Besides I know full well my wife has a lesbian lover she stays over with if and when her father wants to stay the night.
There is a whole lot more to the family im married into. This is just the tip of the iceberg. And believe me it's a very sexual family.
