Building Both Sides

We're two married builders in our thirties. Each of us enjoys sucking cock, being fucked and also fucking a beautiful arsehole.
So nearly every work day either myself or Matt will fuck the other.
Some days it's all about me fucking Matt, other days it's him fucking me. But it's the days when we both take each others cum up our arseholes, that I like the most.
Both being totally versatile, I can honestly say its a beautiful thing we have together.
We've fucked outdoors, in the van, at his or my home and sometimes on building sites or clients houses.
Only last week as I was moving some floor tiles up to a mezzanine level at a clients house, Matt got up behind me, pulled my work trousers down and rimmed my arsehole. A few minutes later he was balls deep inside of me, fucking me so hard I had to grab onto the mezzanine rail to steady our fuck.
Don't worry about the client either, as it was his suggestion Matt fuck me so he could watch and wank.
No sooner had he pulled out from my arsehole after cumming deep inside of me, we switched and I fucked him, much to the utter delight of our older gay client.
The client came shouting out his delight, moments after I unloaded up my building buddies arse.
There's never any pressure on either of us for sex. It happens when it happens, so we're very chilled out about our relationship, which is for us just sex.
