Rented Field

My husband Nick and I married two years ago. He's a successful businessman in his mid forties and very committed to his work, but also our relationship.
Nick has specific kink when he's home, which is usually four to five days out of seven.
He likes me to be naked around our semi rural home, and fucks me on a whim.
I'm twenty four, five feet seven, slim and have feminine cute looks.
Many many times during our relationship and now marriage, he's walked up behind me, bent me over and slid his seven inches up my arse.
It's very spontaneous and usually a short but intense fuck.

This confession is about one such fuck.

Out in the bottom end of our very large garden, I was picking some apples from our trees. Only wearing shorts and flip flops, I wasn't expecting anyone. Reaching up, I felt my husband grip me from behind, although he was supposed to be in London another day. Practically ripping my shorts off, he pushed me up against the tree, but instead of sliding his cock into my arsehole, he spread my arse cheeks and began to tongue my hole.

It felt so good and I could hear his horniness in his breathing. Rising up quickly, he fumbled about then thrust hard so deep inside me.
His cock felt thicker and much more hardened, but I put it down to him being gone a few days.
Fucking me extremely hard, I was being used like a rag doll. Not that I minded, and within a few minutes I came all over the trunk of the tree.

Moving right into me, my husband began kissing my neck, and it was then I knew it wasn't Nick.
Nick is clean shaven, always has been. The man fucking me so wonderfully had a beard and his aftershave was a cheap one I recognised. Not one Nick would use.
Even so, there was no way he was stopping and continued to fuck me.
Grunting loudly in my ear, he spoke for the first time, confirming who he was. Telling me he was going to cum up my arsehole, our neighbour shot his load deep inside my bowels.

Turning me around, I looked at Steven and saw him smile. Saying he'd wanted to fuck me for ages, I looked down to see his still erect cock, and realised just how thick and upwardly curving it was.
Before I could say anything at all, he pushed me down and told me to suck his dick.
Doing as he told me to, I opened my mouth and tasted his cum along his cock shaft and my own anal juices.
It turned me on so much I became erect again.

Still sucking his beautiful cock, I tossed myself off and came a second time, just before he pulled out of my mouth.
Picking me up like I weighed nothing, Steven spoke to me about keeping our fuck just between us. He's married and lives a few hundred yards from our home.
He and his wife rent some land off Nick for their horses, and that land backs onto our garden.
He'd been in there tending to them when he saw me. And what he said then made sense.
He'd watched Nick fuck me several times in our orchard, but usually I'd have been naked with Nick around.
Seeing me, he thought he'd seduce me and see where it lead.

Since our first fuck, Steven has now fucked me several times. He's a more intimate lover than Nick who doesn't like kissing. Steven does and we've had quite a few liaisons down by the river, where we'll spend an hour having sex and kissing.

I'd like to tell Nick about us, as he's shared me several times. But those have been with educated wealthy people like him. Steven is a really nice guy, but isn't rich at all.

Now I'm wondering if I should tell my husband, or have my fun with Steven when Nicks away.
