Away Days Sex

I've been working away from Monday morning to Friday midday with an older man on various groundwork contracts. He's a very strong muscular quiet man in his early fifties who happens to like fucking young men.
Even though he's married, he much prefers to be shagging guys like me. And I know this because almost every night we spend in the caravan, I take his cock down my throat and up my arsehole.

My girlfriend obviously doesn't know about my love of cock, a love my work colleague has taught me to enjoy.
We first had sex getting back from a local pub. I basically woke up to him masturbating only a few feet away. I was totally fascinated by his long thick cock and when he saw that I was awake, he asked me to join him.

He taught me how he liked his cock sucked and after a long time giving him head, he spent an age licking and tonguing my arsehole.
Without asking me, he lifted me into a kneeling position and entered me from behind.
Even though it was my first ever time being fucked, he'd spent that much time rimming me, there was only a limited amount of pain.
But once I relaxed and he really began to fuck me, and the sensations going through me made my cock erupt.
He kept on fucking me until finally grunting and groaning, his cock exploded up my rear and I was filled with his spunk.

We slept together and just as it was getting light, he slid his cock into me again, spooning and fucking me as he kissed my neck. But what really made things perfect for me at least, was when he flipped us around and entered me missionary.
He kissed my mouth at the same time and we didn't stop kissing until he shot his load deep inside of my bowels and I'd cum in between us.

I was knackered all that day and slept when we got back to the caravan that night.
Even so when I woke he had me give him a blow job. And since that week, and every week we've worked together he's fucked me nearly every night. The only times we don't have sex is when we've worked really late, or if some other contractors want to have a drink and play cards all night.

He was on holiday with his wife last week so I've missed him and his cock. Even so he sent me a video of himself wanking on the balcony of his apartment. Apparently his wife was drunkenly snoring on the bed a few feet away as his cock erupted all over his hand.
They flew back in this morning (Sunday) and will be picking me up early tomorrow morning to drive to us and the caravan to a new place. We'll be there for three weeks going home every Friday night. But during next week I'm going to make sure I drain his balls each night.
