About ten years ago when I was married, my wife and I were really good friends with another couple. Their names were Mike and Michelle. They were about our age and they have two kids the same ages ours were. Well, my wife and Michelle were doing a lot of talking about sex and it came up that there were both bi curious and they knew that I was bi and my wife was bi curious also. We all decided that we would start out slow and see where it went. One evening we all had our kids at babysitters and after a night of clubbing, we went back to our place and started to play this XXX rated computer game. The game had you do things to other persons in the group. It started out mild, but the more we played (and with more booze), we got more and more excited. After kissing and feeling up my wife a few time, one of the "cards" said for Mike to "feel up" the person across from him. Well, that was me. We both stood up and went to the side so our wives could watch. I stood there in jeans and a t-shirt and the biggest hard on I have ever had. He came up close and slowly put his hand on the front of my jeans. His hand cupped my balls and he rubbed my cock through my jeans. All I could do was moan and push toward his hand. He kept rubbing my cock and I could feel the head of it leak pre-cum. Michelle told mike to pull my cock out and my wife agreed. Mike unbuttoned my jeans and slowly pulled them down. He'd grabbed my underwear at the same time and my cock pointed straight up it was so fucking hard. I heard a gasp and an "OH MY GOD! That's beautiful!" come out of Michelle's mouth. She was talking about my rock hard 8" cock. "That's HUGE! How can you handle it?" she said to my wife. I looked at my wife and she was blushing. Mike put his hand on my cock and slowly wrapped his hand around it. His hand barely fit around my girth and he started to stroke it. Both Michelle and my wife got up from the table and came over to us. Mike was now on his knees and his face was inches away from my cock. "Suck it babe." Michelle said to Mike. "You know you want to." "That would be so hot!" my wife said. I just stood there, waiting for Mike to make his move. My wife never really got into sucking my cock because she had a really small mouth and could only get maybe two or three inches in her mouth and her jaw got real sore after a about 5 minutes of trying to suck me. I closed my eyes and waited. At that point I felt another hand on my cock and when I opened my eyes, I saw that it was Michelle's. My wife was encouraging Mike to suck it and I felt his mouth cover the head of my big cock. His mouth was so fucking hot. He slowly went down on me. I felt the head of my cock touch the back of his throat. I was in heaven. His lips closed around the base of my cock and he gave me a suck. My hands went to his head and I started to fuck his face. I totally forgot about Michelle and my wife as I enjoyed the first deep throat of my life. I lost track of time as I fucked Mike's face. Mikes hands were on my ass, spreading them and playing with my ass. Then I felt him open my ass checks as wide as they could go and then something wet touched my asshole. I opened my eyes and glanced over my shoulder. Michelle was nude, down on her knees, on my wife's face, eating my ass. Her tongue was probing my ass and I was in heaven. I felt my knees starting to get weak and I was getting ready to shoot my load. I told Mike I was close to cumming and with that; he started to "slam" his face against my groin. I could feel the tongue on my asshole being replaces with a finger. Then it was two fingers. My ass opened up for the invasion and when Michelle had three fingers in me, she massaged my prostate. That did it. I couldn't hold back my orgasm even if I wanted to. The first shot went right down the back of Mike's throat and as he pulled back, the second landed right on his tongue. Michelle was now finger fucking my ass and my third shot hit Mike right between the eyes. My knees buckled and I almost fell, but I caught myself by holding onto Mike's head. Michelle pulled her fingers from me and everyone disengaged. "Let's go to the bedroom." My wife suggested. Everyone agreed and we all went to the bedroom. We had a nice big California King bed and all four of us fit on it with ease. Mike had taken all of his cloths off by now and both Michelle and my wife were nude. I took the rest of my cloths off and asked what we were going to do next. Michelle said she wanted to see two guys fuck. I was up for that and I could tell Mike was too. Mike's cock was about 6" long and 4" around. He had a nice big head though and I knew from past experience I would enjoy it. I love bigger cocks (9"+ and real thick), but his had just the right curve to hit my prostate if I rode on top. I told Mike to lie on the bed and I asked my wife to get the lube. I had her lube up Mike and Michelle worked on my ass some more to get me ready. My cock got rock hard in a matter of moments and Michelle came around and tried to suck my cock while she finger fucked me. My wife climbed On Mike's face and he ate her out. I moved away from Michelle to climb on Mike's steel hard cock. Michelle aimed his cock at my ass and I slowly sank down on it. Once his cock was balls deep inside me, I moved up and down on him. Michelle stood in front of me and I ate her pussy from the front as my wife ate her ass out from the rear. I would alternate fucking up and down with a grind motion. It felt so good having a cock inside me and a pussy in my face. Mike grabbed my cock and stroked me; I was in heaven! Mike didn't last more than 5 minutes before I felt his cock throb and then my insides felt real warm. His cock throbbed 6 times total and he shuddered. His whole body went limp and so did his cock. When his cock came out of my ass, I could feel the river of cum pour out of me. Man! He must have dumped a quart of cum up my ass. We all moved apart and lay on the bed. I was still rock hard and horny ass fuck. My wife was on her back and she spread her legs. I moved up and slide my cock into her wet hole. Michelle shifted around and her face was at my ass. She drank the cum as it came out of my ass. That girl LOVED to eat ass. Having her tongue in my ass was the best. It made it hard to fuck my wife, but I didn't care. Michelle's tongue in my ass was great! I finally forgot about fucking my wife and got on all fours. Michelle just dug into my ass and her tongue seemed to go up inside me forever. While this was happening, I ate my wife and she stroked Mike's cock. My wife said it was time for Mike to get his ass fucked. My wife went over to the dressed and pulled out our toys. My wife loved it up the ass, but because I'm so thick, we couldn't do it that much. To help her open up, I had bought some butt plugs of different sizes. Mike got on all fours and Michelle went from my ass straight to Mike's. She went crazy eating his ass with the knowledge that I would pop his cherry. It turns out; he's had toys up there, but nothing as thick as me. I stroked my cock and added lots of lube to get myself ready. I also grabbed my inflatable butt plug and feed it up my ass. It had a bulb pump and a vibrator. It feels so good with it inflated and vibrator on. I gave it about 8 pumps and turned the vibrator on half way. My cock was throbbing. Once Michelle thought Mike was open enough, she told me to fuck him "like a bitch". My wife got out the video camera and Michelle got the Polaroid camera. I grabbed Mike's hips and pulled him close. His face was buried in a pillow and he thrust his ass up high. His asshole was open, but not nearly enough to handle me. "You want it Mike?" I asked him. "YES!" he moaned. "Tell me how bad you want it BITCH!" I asked him again. "OH! I need your cock sooooo BAD!" He moaned into the pillow. I put my cock right at his open ass and asked him one more time how bad he wanted it. He didn't reply, he just pushed back with all his might and my cock sunk so deep inside him I thought it was going to come out his mouth. I grabbed his hips and readied myself for the pounding I was going to give him. Michelle told me to fuck his ass hard and my wife said for me to "fuck the bitch". My wife had never talked like that before, but with all of the sex in the air, she was intoxicated by it. I slid out of Mikes ass very slowly till just the head of my thick cock remained inside him. I waited just a moment, then I rammed him so hard, his head hit the headboard. I then proceeded to fuck the life out of him (I was going to say "shit", but that just seemed weird to say that). I fucked him silly for about 15 minutes before he begged me to stop. I told him to hang on a second because I wasn't ready to stop just yet. My cum was building in my balls, but it would take more that just fucking him to get me off. I reached behind me and grabbed the control to the vibrator. I turned it up full blast and then I felt my cock enlarge so big it was going to burst. My orgasm seemed to last forever. The shot of cum came out as one long stream that felt more like I was pissing inside Mike's ass than cumming. After my orgasm was over, I pulled out of him and Michelle came over with the camera and took a few pictures of Mikes gaping asshole. I was surprised that my cock was hard as a rock. But before I would do any more fucking, I needed to take a shower. I got off the bed and went to the shower. When I left the bedroom, Michelle was eating Mike's ass out and my wife was filming it. I took a real quick shower and when I returned, I came into the room with my wife wearing a strap-on and fucking Michelle doggy style. Mike and I got into a 69 and sucked on each other for a bit till he was hard too. Then we told our wives it was "DP time". Mike and I took turned double penetrating each other's wives for the next few hours. My wife loved having Mike up her ass because she could handle a lot more fucking up there because his girth isn't as large as mine. Michelle on the other hand loved the feel of my cock up her ass because it made her feel so full. Mike and I took turned fucking each other two more times that night; the second time he lasted long enough for me to cum just by him fucking me. I rode on top and not once touched my cock. It wasn't a big orgasm, but the shot was strong enough to him in the face. Michelle and my wife also used strap-ons on us at a later meeting. Of the times that we got together as a couple, we did every combination you could dream up. Once or twice we tried to triple our wives by putting a cock in their ass, a cock in their pussy and then whom ever was wearing the strap-on would kind of sneak in between us and feed in into the pussy. We saw it in a porno and had to try it. Unfortunately, Mike got transferred and had to move. I would love to go back to those times with my cock up his ass and Michelle eating me out.
