Desperately Needing The Money

My boss has been using my mouth and arsehole, as his own personal cum dump for nearly nine months.
Most week days I'm either on my knees in his office sucking his thick cock, or I'm leaning over his desk as he fucks my arsehole. And he always empties his balls down my throat or deep inside my bowels.
And all because of a gambling debt I couldn't have my girlfriend find out about.
Her father died because of gambling, so I knew she could not become aware of my betting disaster. Thats why I paid back the gambling money I owed with a sex loan from my boss.
He paid off what I owed and I immediately began paying him back with my first ever blow job.
Although he thoroughly enjoyed it, I didn't at first, yet I knew I needed to pay him back. However the first time he fucked me, a few weeks after I began sucking his cock, I really enjoyed the feeling of his cock inside my fuck hole.
He never lasts too long either way. I'd say five to ten minutes max. But he likes to fuck both orifices hard, which has since around the first couple of fucks, has made me cum every time.
Now I don't owe him any money, but I still adore him fucking me.
He tells me I have a beautiful fuck hole and he now often fucks me more than once a day. Nine months ago, I'd never have believed I'd love gay sex so much, yet here I am typing this with an arsehole full of his cum, after not seeing him for a week.
