Paying The Rent

My names Luke, I'm twenty two years old and share a house where the three of us living there, all have self contained studio flats.
However I'm the only one paying, direct, rent.
The other two pay me three quarters of their monthly rent, and I pay the landlord Greg half of what we all owe, and pay the rest in sex.
He visits whenever he wants, morning, afternoon or at night and fucks me for however long and ferociously hard he likes.
We worked out the deal when he began having work done on another property he owns, and was converting into studio flats.
One of the builders and I got friendly and he began calling round for sex. Basically Greg caught me sucking his dick one afternoon and stayed to share my mouth.
The next day he called by to enquire about the rent, but in reality it was to see if I'd let him fuck me.
That's when thinking on my feet, I suggested all three of his tenants pay half rent, he gets to fuck me whenever he wants, and I'll pay him for all three flats.
Only I charge the other two a quarter fee, for my services and they save eighteen hundred a year.
I essentially have a rent free studio flat and a landlord fucking me, who's cock is the thickest I've ever been fucked by.
It's eight inches long, but also six and half inches around. And every inch in the past fourteen months has been deep up my arsehole.
He calls me his fuck toy and hopes I'll be staying for sometime yet. He knows about my rent agreement with the other two, but doesn't care.
Every week now, he stays over at least once, and we have spent a week away together.
He's not the best looking guy in the world, but he's my guy. And for a fifty two year old, he can fuck and fuck and fuck.
His wife couldn't care less about him fucking me, and I've even heard her saying he should move me into their home. But I know he likes fucking me in my flat away from his home life.
He has the best of both worlds, and I live rent free. With a man who has more sexual energy than most guys my age.
