Trying Dan

After Gina had left my wife and I lay in bed and discussed the decision I'd made.
In the heat of the moment, I'd agreed that she could fuck Dan, and because I'd not actually cum during my last orgasm when Gina rimmed me, I was still aroused.
"I'm so glad you agreed to let me have sex with Dan, honey," my wife began. "I think it's about time we broadened our horizons... you know spice things up a bit. I really want to feel his big one in me."
She leaned over and kissed me passionately, her tongue licking my lips.
"Yea, I guess, you're right. This is just a one time thing though, okay?"
"Of course, honey. I just want to try a big penis, but I don't love him."
I must have not looked convinced, as she continued, "I let you have sex with Gina, because I knew you loved me, not her. It was just sex. And you still love me don't you?"
"Yes, of course I do."
"Right, well it'll be like that with Dan. I'm only going to use him. Think of his penis as a dildo for me to play with. My heart will be yours, even when his penis is in me, honey."
"Okay..." I said, thoughtfully, "but how are we going to do this, get him to fuck you I mean?"
"Don't you worry about that. I'll think of something," my wife finished up the conversation and moved down under the covers to again suck me. Like Gina had done though, she began licking my arsehole as she stroked my cock, and it wasn't long before I came in her mouth. She now seemed to enjoy it and simply swallowed my cum with a smile.
She curled up beside me again after turning out the lights. "Goodnight my love."
"Goodnight babe," I replied before drifting off to sleep a minute later.

The next day I was at work, I noticed my wife's car in the parking lot as I left for the evening. She'd not come in to see me though so it was a bit unusual. I contemplated going back up to see if I'd missed her in the lifts, but decided to just text her instead.

Hey honey, where are you? I'm just leaving work and noticed your car.

I waited, leaning against the side of the car for her to reply.

Oh, I'm just getting my face done. I'll be a while so I'll meet you at home.

Oh, great I thought, more money down the drain on 'beauty treatments'. Why do women waste their time on those? They always look exactly the same afterwards. I headed home, without bothering to reply figuring she was busy.

An hour later I was getting hungry, and when two hours rolled around I decided to just grab some takeaways instead of waiting for Melanie to get home. It was another hour later when she finally arrived, and as expected she didn't look much different. If anything her face had a bit of a blush to it, and they'd messed up her hair a bit.

"Hi honey, sorry I was so long," Melanie greeted me as she came in. "I'm just going to have a shower and I'll be back out."
"Okay", I replied automatically. I'd waited three hours for her to get home, what did another 10 minutes or so matter. A minute later though, and I'd changed my mind. I decided to go in and join her. I was a little horny still, from seeing Gina all day and not fucking her again, and thought I'd go in and maybe fuck in the shower. I opened the door to the bathroom and was greeted with a thick soup of steam. My wife always had the shower really hot, and with the windows closed the air became drenched. I was removing the last of my clothes as I noticed my wife's panties lying beside her skirt. They appeared to be full of thick white cream. I picked them up to look at them and caught a pungent whiff of semen. Although I'd just had sex with her last night and cum in her, this couldn't be mine. It was still white and thick. Fresh. My cock rose as I stood there holding her semen filled panties.

I opened the door to the shower, "care to explain?" I said simply as I held out the soiled garment.
"Oh, I'm sorry you saw that," Melanie said looking a little shocked. "I was going to clean up and then tell you."
"Tell me what?"
"Well, I did it. I had sex with Dan."
I looked at her panties again.
"That's his." She took them and threw them away as she pulled me by my hardness into the shower.
As she started stroking my erect cock with her soapy hands she began to tell me what had happened.
