Should I Share Her

A couple of months ago my wife came home from a hen night out around two am absolutely drunk. I had to get her from the taxi and carry her into our lounge.
Putting her on the sofa I could see cum all over her face.
After quizzing her for a couple of minutes she admitted she'd sucked off the taxi driver, who had unfortunately gone.

Pressing the issue, she finally confessed to having had several one night stands and two affairs during our four year marriage, stating my cock didn't satisfy her needs.
I don't know why, but hearing her telling me about her lovers had my cock ragingly hard, so I fucked her on the sofa from behind.
Seeing her arsehole twitching as I screwed her I couldn't resist. Pulling out of her pussy, I then slid it up her arsehole. And even though she moaned and tried to pull away, I fucked her arsehole even harder.
When I came I held myself inside her until my softening cock slid out.

Taking her to bed, I stripped my wife naked and couldn't stop thinking about what she'd told me as I spooned her.
During that night I fucked her again and did something I've never done, I came all over her face and hair, adding my cum to the taxi drivers.

The following morning she asked me all kinds of questions, but tried to avoid repeating what she'd confessed.
It didn't work as I let her know what she'd said. I also let her know how turned on I'd been.
Even though she was hung over, she still gave me a blow job in our kitchen once she saw I had an erection in my shorts.

Now two months on my wife goes into detail about all the times she's had sex with other men during our marriage. We always have such amazing sex afterwards and I now fuck her arsehole every time.
She's told me it'll never happen again as she's so happy with how we are now, but I secretly want her to fuck other men, as it gets me so horny thinking of her doing it.

After all she's no longer the only one to have cheated.
A week or so after my wife attended the hen night, I had sex with a young colleague from work.
She'd been flirting with me for a while, so thinking i could get back at my wife, I fucked her in my car during our lunch break. My colleague isn't the best looking twenty year old girl out there, but she's a dirty little bitch who seems to really love my older cock.

We've fucked many times over the last couple of months, and I've even had my wife suck my dick once I've gotten home after fucking my colleague the same afternoon.
But it's when my wife and I fuck after or during her descriptions of her lovers fucking her, that I now enjoy the most. I just wish I could convince her to enjoy other men again. And maybe with me present.
