Love Watching Her Fuck

Right now we're all relaxing after a wonderful morning of sex.
When I say all, I mean myself, my wife Ellie and her twenty nine year old boyfriend Rob, who has a very large cock.
They began fucking after meeting at the gym. I caught them having sex two months later and couldn't believe how beautiful they looked together.
There was no jealousy in me whatsoever, which surprised me given my normal persona.
That day I experienced an orgasm just from watching my wife taking Robs cock deep up her ass.
This morning I joined in which isn't usual, but then this morning wasn't the usual sex.
We did just about everything together, and yes that also meant some gay interaction between Rob and me. Ellie freaked but in a good way, playing with her pussy and tits as Rob fed me his enormous cock.
Once he was raring to go yet again, I lay under my wife as he fucked both her pussy and asshole, making Ellie orgasm many times over.
It's definitely something I'm getting more and more into. Especially seeing my wife taking huge cock, cock I get to taste and suck.
