My fortieth birthday party was coming up, and I was frankly dreading it. Forty is such a big milestone and a time for reflection. I was no longer young, but rather middle-aged. My wife, Diane, was trying to cheer me up, and she'd often flirt with me to remind me that she still found me sexy.

As the birthday came closer, Diane asked if I was OK with her planning the celebration.

I said, "Sure," and she had the biggest and most devilish smile I had ever seen on her.

When my birthday rolled around, Diane said to hop in the car for dinner. Diane told me to drive to this fantastic restaurant in a nearby town.

On the drive over to the restaurant, Diane said, "I know you're feeling a little bummed about the birthday, but I promise you, you'll be very happy with tonight's surprise."

We got to the restaurant, and the menu was spectacular. It didn't take long for me to decide on the 16-oz ribeye steak. Diane ordered the whiskey salmon. We flirted while we waited for dinner. I could feel Diane rubbing her foot up my leg as she said, "I'm feeling a little uncomfortable in this skirt. It definitely feels different when I'm not wearing any underwear."

This caught me a bit by surprise. Diane was very adventurous sexually, but it was always in a private sense. We had a few sexual experiences with other couples; however, she had never been much of an exhibitionist. My brain started going into overdrive thinking about the sex that was to come, and my cock did a little stir.

Dinner arrived and it was fantastic.. Dinner was amazing. The steak with red wine was a perfect pairing, and Diane seductively ate her salmon. It was delicious, but my mind was really on the sex that was to come. It didn't hurt that Diane would occasionally run her tongue along her food before she slid it into her mouth.

At one point, I ran my hand along her thigh, which made her squirm a bit. She opened her thighs initially, but then realized other people might see her. She smiled devilishly and pushed my hand away as she said, "Later, Baby. I promise you, this will be a night you'll remember."

After dinner, we drove home with my mind racing, thinking about the sex. Diane hiked up her skirt as I drove and slid a hand up under her skirt. She casually started talking about dinner, the evening weather, as I could see she was rubbing herself under the skirt. I couldn't believe it!

Finally, I slid a hand over, pulled up her skirt, and slid a finger into her. She grabbed my hand and pulled me in deeper as she put her head back. Her lips were so soft and wet. It was hard to focus on driving. Diane started rubbing her clit a bit faster, slid a finger deep into her. She then pulled it out and brought it to my mouth to suck on. Her pussy juice always tastes so good. My cock was just about ready to break through my jeans. I was so turned on it hurt.

Somehow, we eventually made it home without crashing, and I noticed a Porsche Cayenne was parked in our driveway, and the lights were on in the living room area. Diane asked, "Are you ready for your surprise?"

My mind was racing, but I figured Diane had arranged for one of our friends to come over to celebrate my birthday. My mind was trying to sort through who it could be, as I had never really paid attention to their cars when we'd met before. When I walked into the living room, I was pleasantly surprised to see Steve and Sandi there. I always felt incredibly comfortable around them, and obviously, Diane felt like she could be herself with them as well.

Sandi said, "Tom, Diane said it was your birthday, and we wanted to make sure it was an extra special birthday surprise for you. Are you OK if we all celebrate together?"

I must have looked like a teenager ready to have sex as I said, "Am I ever! It's so good to see you both again. I was hoping we could hook up some more."

Steve brought in a small chocolate cake, and they had already opened a bottle of wine. They all sang Happy Birthday, and we enjoyed the cake as we all settled in for what was to come next.

Diane had sat next to Sandi and was whispering in her ear something that I could not hear. After they finished their cake, the ladies got up and walked over to me.

Sandi asked, "Are you ready for your special gift?" She gently rubbed her hand up my crotch, which made my cock ache to be released. I nodded quickly in response.

Diane unbuttoned my pants and gently tugged them down. My cock was half erect already and bounced slightly as it was released.

Sandi grabbed it around the shaft and gently stroked it, making it fully hard. Diane whispered, "Baby, you're going to enjoy this so much."

The ladies pushed me to the couch and got on their knees in front of me. Diane engulfed my cock as Sandi rubbed her hand up Diane's back. Diane was going nice and slow, teasing the cock as she licked up and down the shaft.

After a few minutes, she pulled her head up and looked at Sandi, asking, "Do you want a taste?"

Sandi replied, "I don't mind if I do." Diane fed my cock to Sandi and postured herself behind her. She was rubbing her breasts against Sandi's back and had a hand down around Sandi's crotch.

Sandi paused a minute with a huge gasp of air as Diane slid a finger into her. She said, "Oh my god, this is so incredible," as she went back to work on my cock. She was bobbing up and down on it.

I pushed her hair away from her face so I could watch my cock sliding in and out of her mouth. She then looked up at me with those gorgeous brown eyes, and I just about lost my load right there. I had to grab her by the shoulders to not cum right then. My breathing settled down, and I got to enjoy the moment of watching Diane please Sandi.

I looked over at Steve, who had pulled his cock out and was gently stroking it. It was nice and hard. It was just about that perfect cock where it's straight with just a little bit of curve to it. I remembered how good it felt in my mouth and hoped I'd have the chance to suck on him again tonight.

Diane looked up at me with her gorgeous blue eyes and a smile that could light up a room. She asked, "So, birthday boy, what shall it be? It's your party."

I knew exactly what I wanted. I said, "I want to eat one woman, while another rides on my cock." This had been one of my ultimate fantasies my entire life, and I could not believe it was about to come true.

Diane asked Sandi, "So, which position do you want?"

Sandi replied, "I want to be riding the cock."

The ladies led me to the bed and had me lie down on my back. My cock was so ready in anticipation. I couldn't wait.

Diane knelt on the bed next to me and rubbed her hand up and down my chest. She brought it down and rubbed my shaft and balls as she said, "My, my, it does look like you are enjoying this."

Diane then straddled my shoulders. I had this perfect view of her pussy and asshole. Her ass was just so gorgeous, and I knew how much she got turned on when I played with it, so I reached up with one hand and started massaging her ass cheek. I let a finger slowly start rubbing closer to her hole.

Diane pushed back slightly so her pussy was directly above my mouth. With my other hand, I pulled her thigh so she knew she could lower down onto my waiting mouth. Her lips were already wet, and I loved the smell of her nectar.

Not being able to see anything other than Diane, I knew at some point Sandi would mount me. First, though, she started sucking on my cock. Wow....I was in heaven, and I just let myself feel the moment. Sandi's mouth bobbing up and down on my shaft and licking Diane as I fingered her ass.

It surprised me a little when Diane reached back and grabbed my hand that was playing with her ass. She held it firm and pushed it up against her, and the finger slid right into her anus. It was just a little, maybe half an inch, but I could feel her thighs tighten up on my shoulders as the pleasure shot through her body.

Sandi had stopped working my cock with her mouth and decided it was time to get down to business. I could feel her straddle me and position my cock against her pussy. It slid in easily, and she started rubbing back and forth.

This was so intense! Having two women at the same time was incredible. I had to grab Sandi's hips to hold her still so I did not cum too quickly.

The women both leaned forward and started rubbing their hands over their bodies, and kissing. Diane let go of my hand to massage Sandi, but I knew what she wanted. I kept my tongue active on her pussy and fingering her ass.

Sandi started grinding again on my cock, and I knew I was going to cum. The pleasure was too much. Too much sex. It was building. I could feel the load getting ready. Sandi leaned back a bit, and I could feel her hand on my stomach as she rubbed her clit with a lot of fury.

Sandi said, "I'm so hot. Tom, your cock is incredible, and I need to have your cum."

That's all it took, and I started shooting a huge load into Sandi's pussy. I grabbed her hips and helped push her back and forth on my cock. I felt her body tense, but kept pushing on her, as the second part of my load filled her up. She leaned forward into Diane, who held her body up, as Sandi and I finished our orgasms.

We slowly settled down, and I could feel the cum drip out of Sandi's pussy. She slid off me and, to my surprise, started slurping the cum off my cock. Diane slid off me, and I looked up. To my surprise, it was Steve who was cleaning my cock.

Steve said, "Sandi tastes so good on you." He then went back to licking up all the cum that was on my cock and around it.

Wow....what a birthday surprise this had been.

Diane asked, "Are you all good now?"

I replied, "I'm good, but I don't think you and Steve have had your chance."

I then spun around on the bed a bit, so I could reach Steve's cock. It was rock hard, and he knelt up and let me just stroke him. After a minute, I knew what I wanted and knelt forward and took his head right into my mouth. It was that strange mix of spongy and firmness. I took him deeper so my saliva would fully coat his shaft. I then really went back to bobbing up and down on his head and stroking him.

Diane said, "That is nice, honey. You are doing such a good job there. Steve is loving your mouth on his hard cock."

I looked over to Diane, who was lying down on the bed next to me. She was looking deep into my eyes, and I looked down further as Sandi had positioned herself between Diane's thighs. Diane was in ecstasy as she grabbed my hand with hers. She squeezed tight to let me know how much she was enjoying my birthday party.

After a few minutes of me pleasing Steve and Sandi pleasing Diane, Diane said, "This is great, but I'm really needing Steve's hard cock."

Steve was more than happy to oblige as he positioned himself on top of Diane and easily slid into her. They both let out huge moans of pleasure as they held still for a few minutes. Diane then started thrusting her hips forward and pulling Steve deeper into her. Diane's legs went up into the air to let Steve put the full length of his manhood into her.

They went at it for just a few minutes, and Diane screamed out, "I'm cumming." She then tensed up as Steve started shooting his load deep into her. It is such a turn on to watch Diane cum on another man's cock.

As Steve slid off her, Sandi asked, "Tom, aren't you going to clean up Steve just as he did for you?" I was happy to clean the juice and cum off Steve's cock. It was that tangy, salty flavor. It was such a turn on that after I cleaned his shaft, I started licking the cum out of Diane's pussy.

As I was cleaning Diane's pussy, I felt Steve and Sandi start massaging my ass and cock. I had thought I was spent for the night, but apparently, my cock had different ideas. This was truly the best birthday party ever.
