Since I was now operating as a single guy, I decided to answer some ads in a swingers magazine. I tried to look for couples who wanted something unusual, and I mentioned in every reply that I was willing to try anything that wasn't dangerous or painful. None of the ads I answered had mentioned bi sex, but I figured that any guy looking to share his wife with another guy was probably secretly thinking about trying it. It turned out I was pretty much on the money. I got a positive reply from more than half of my letters, but one in particular really caught my attention. Mike and Charlotte wanted to know if I really meant the part about trying anything. They had talked with each other many times about a number of "really kinky" things they wanted to try, and if I was serious we had to meet. I told them I definitely was, and we arranged to get together. We were to meet in the bar at the hotel where I stayed while in town doing business with the local college. I got there early so that I could watch them enter in case I didn't like what I saw and decided to duck out. I didn't have to worry about that---not one bit. When they first entered the bar Mike said something to Charlotte and immediately went to the men's room while she took a seat at the bar as I watched from a corner booth. Since she wasn't looking around I assumed it wasn't them, but I sure wished it was. Charlotte looked like if I got within five feet of her I would smell sex. She radiated it; pretty but not drop dead gorgeous, just sexy---very sexy. I was really disapointed that it wasn't them. When Mike returned they talked for a minute, then he turned and scanned the room until he saw me watching them. When I didn't turn away he tapped Charlotte on the shulder and pointed me out to her, then the two of them walked toward me as I started growing a hard-on. I hadn't even noticed what Mike looked like---not that it mattered--but I was spellbound by Charlotte. I can't remember ever being that close to cumming in my shorts. It was them. We talked in the booth sharing several beers until I decided I couldn't hold it any longer and said that I had to use the men's room. Charlotte said that was the last time I was going to do that without supervision. I didn't know what she meant, but I really had to go so I said OK and left. When I returned, Charlotte was sitting all the way into the seat where I had been sitting, and Mike was across from her with their coats occupying the rest of his seat so that the only place open for me was next to Charlotte. Just as I decided that was probably a good sign, Charlotte patted the open space next to her and told me to sit. Mike started to tell me that they had decided to give it a try with me, but I could barely understand what he was saying because Charlotte had already run her hand all the way up my leg and was rubbing my growing cock. I wanted to go to my room immediately, but Mike ordered another round of beer and said we could go when these drinks were gone. Once we finally got into the room, Charlotte said that she had to pee and asked if I had ever seen a woman pee. I said I had been in the room when my ex-wife pissed many times, but she wanted to know if I had ever really watched it come out. And once again my dick got even harder as I said "No, not really". She had me follow her while Mike waited smiling, and told me to get on my knees in front of her as she dropped her pants and sat on the toilet seat with her knees spread. She had me put my hands on her legs and shortly a stream of piss began to flow from her pussy. It really turned me on, and I offered no resistance when she took my hand and placed it into the stream of piss. Then she lifted it to her mouth and licked the piss off and returned it to collect more piss. I was getting tremendously excited feeling the warm piss hit my hand, and when she put her own finger into the stream of piss coming from her pussy, and then put it into my mouth, I sucked it like it was the most natural thing in the world. And I loved it. By then I had to piss again, and when I said so she told me that she wanted to watch. I told her that I couldn't possibly hit the toilet with a hard-on, so she led me to the tub and said for me to piss on the tub wall. It took me a long time to get it going, and as soon as I did she put her finger in the stream and then into her mouth. She did this several times, then she put her finger, dripping with my piss, into my mouth saying that she didn't want to be greedy. It was really turning me on. When we returned to the bedroom without our pants we found Mike sitting in a chair naked except for a T-shirt, smiling and stroking his hard cock. Charlotte asked what I'd like to do first; that we should take turns deciding what to do and that the others had to go along. I said that I'd like to bury my face between her cute butt cheeks and stick my tongue up her ass until her pussy dripped, and Mike suggested that she bend over and suck his dick while I did. She was in position in a heartbeat so I got on my knees behind her and spread her cheeks with my hands as I pressed my nose on her tiny puckered hole and inhaled. Man! I love that smell. I circled the outer edge of her asshole with the tip of my tongue for a good minute or so and then began lightly licking the opening as I slipped finger into her pussy. I could feel her vagina contract on my finger every time I pressed my tongue against her ass. At first she was too tense for me to get in, but after awhile she relaxed a little and I was able to get an inch or so of my tongue in before she clenched again and squeezed it back out. I kept it pressed there firmly and pretty soon she relaxed again and in it went, only to be squeezed back out. She began to repeat the squeeze and relax cycle every few seconds and I could feel her gripping my finger at the same time. I used the thumb of my other hand to rub gently on her clit, and very shortly I felt her juices running down my arm. Then her contractions went on auto pilot as she started an orgasm. Her asshole squeezed tight then opened up rapidly as she moaned, and I heard Mike tell her to stop biting his cock. Her whole pussy and asshole area were pulsating and I began to lick her from her clit to her tailbone until she reached back and made me stop because she had finished her orgasm and was too sensitive. I held the tip of my tongue against her asshole for a few minutes more and it continued to contract every once in awhile as she wound down. She told Mike to pick something that he wanted, and he said that he wanted to see her piss on me and have me lick her pussy when she finished. We put several towels on the floor for me to lie on, and Charlotted squatted over me and started pissing on my balls, and then up the shaft of my cock and onto my belly. It felt far sexier than I had imagined it would, and I found myselt anxious to taste her pussy and the drops of her piss that would be clinging to it. When she stopped pissing she turned around facing toward my feet and lowered her dripping cunt onto my open mouth. As I licked and sucked, she bent forward and started licking her piss off my belly and then off my balls, and then asked me if I liked the taste. She lifted her pussy off my face so I could answer, and when I said yes she asked if I would like some more. I said yes to that too, and she promptly lowered her pussy back onto my open mouth firmly and let loose with with a strong stream of piss. I held my tongue in the stream to keep it from shooting down my throat and choking me, but pretty soon I had to start swallowing because her pussy was pressed so tightly against my mouth there was nowhere else for her piss to go. I swallowed several times before she lifted off my face a little and I let the rest run out the corners of my mouth. By this time she was sucking my cock and Mike said for me to piss in her mouth; that she loved drinking piss. Again I had a hard time getting started, but when I finally did she kept her lips sealed around my cock and swallowed every bit--almost. When I finished she turned around kissed me, and when I opened my mouth for her tongue I got a mouthful of my own piss. After the two of us rinsed off in the shower Charlotte said that it was her turn to direct the activities. She said that Mike had told her that when he was in the Navy he and several other guys would take turns fucking each other in the ass and sucking each other off after the lights were out. She wanted to see him do that with me. I hadn't told them I was bi, but I said that I really wanted to try it. Mike and I flipped a coin to see which one got to cum first and he won. Charlotte had me bend over the bed like Mike had told her they did aboard ship, and she got on her knees behind me. At first she used her tongue on my asshole like I had done to her, even pushing it in several times. I really didn't want her to stop. Then she put some lotion on her finger and slipped it in and out of my ass while Mike put on a condom. The biggest thing I'd had in my ass until then was a finger, but Charlotte assured me I could do it and that I would like it. Mike got behind me and pressed the head of his cock against my asshole and held it there for a few seconds, and Charlotte told me to grunt like I was trying to go to the bathroom. I did, and I felt my asshole relax and open up as Mike pushed his cock in. It stretched but it didn't really hurt. In fact it felt pretty good. He pushed in slowly until I felt his hips against my ass, then he stayed still for a minute to let me get used to it. Charlotte asked if I liked it, and when I said yes she told Mike to fuck me for a while but not to cum. He started slowly at first, picking up speed until his balls were slapping against mine. I really don't know why so many women say they don't like being fucked in the ass. It feels fantastic. When Mike said that he was getting close to cumming, Charlotte told him to stop. He pulled his cock out of my ass and took off the condom as Charlotte got me on my knees in front of him. She guided his cock into my mouth and as I started sucking it she said that she was going to get his ass ready for me. She went behind him and stuck her tongue in his ass. It got him ready alright--ready to cum. He started moving his hips back and forth and came almost immediately, and when he finished I made sure to milk every last drop from his cock and swallow it which really turned Charlotte on. She couldn't stop talking about how cool it was to see a guy get fucked in the ass and swallow cum. Since he had just cum, Mike really wasn't all that interested in taking his turn, but Charlotte got him to bend over the bed and "take it like a man." I went extra slow with the initial entry and the fucking and before I was getting close to cumming he had gotten a hard-on again and sucked me eagerly, swallowing my cum like he said he had in the Navy. I was so turned on by the whole thing that I ended up sucking him off again later while Charlotte sucked me off, and after they had left I got a hard-on thinking about what had happened and I jacked off on the sheet. I really wanted to see them again, especially when Charlotte said that there were some other things she wanted to try sometime.
