Holiday Return

On a recent holiday to a Spanish island, my husband persuaded me to indulge in a threesome with a guy who we met around the pool.
The sex was amazing, especially as the guy has a massive cock.
My husband was drunk at the time, so once he'd cum he pretty much fell asleep.
The following morning with our guest gone, my husband asked me if I'd been fucked by the guy.
I lied and said "He left when you crashed out".
In reality I'd had over two hours of wonderful sex with the relative stranger, taking his beautiful cock in all my holes.
When we saw him later lay by the pool, he acted just as we'd agreed the night before, and that was cool and looking a little disappointed.
The thing is, Max, the guy from our holiday, only lives twenty minutes away and since returning we've had increasingly fantastic sex whenever we get the opportunity.
My husband doesn't know it, but he's tongued my pussy more than once with Max's cum still fresh from sex with him.
I know it's cheating, but my husband opened the door for me so to speak. I've just stepped through and am enjoying what I've found.
