HOW I LEARNED ABOUT SEX Part 5 Karen and I straighten out our Merry Widows, they had gotten twisted around some with all of our "warm up" activities. The we went upstairs to get some cool drinks and and ice to take back to the Rec Room. I know that I had worked up a thirst with what had already gone on, and would probably be even thurstier later. While we were back downstairs, the door open and then closed, and Karen called out "Hi Honey, who's home?" Her brother Carl answered with a simple "Carl" and Karen told him to take off his clothes and come down to the Rec Room as she had a surprise for him. A couple minutes later this nice hunk walks into the room, with about seven or eight inches of cock at half mast. When he saw Karen and myself both standing there in our Merry Widows (that didn't hide a thing and accentuated what we wanted him interested in) we got paid a very nice compliment. His dick moved from hanging down at a 45 degree angle to pointing up at a 60 degree angle and seemed to get a little fatter, while he said "NNNiiiccceee"! Karen, being the good hostess, introduced me to her brother. He smiled and said that this was definately a surprise as Karen had never brought anyone home for sex games before, and based on how we were dressed he was fairly sure that was why I was there, and he was very happy to see me. I sid that it was obvious that he was happy to see us, his dick had already told me that. Now if he would come over and kiss me hello, I would probably kiss his dick hello in return. He came over to me and gave me a very nice kiss, pulled back and said "hello" then kissed me again and slid his tongue into my mouth to play tongue tag. Very Nice! While he was doing that he started to cup and squeeze my boobs, so I started to grind my pussy against his crotch. That chunk of man-meat felt nice. He broke the kiss and told me that he liked our outfits, and liked the color of mine the best. Themn he said that he liked the way it pushed my tits up to make the nipples beg to be sucked on. So I told him what was he waiting for a written invitiation? He dropped his hands down to squeeze and massage my ass cheeks while he was biting my nipples. He would lightly push his teeth against the outer ring and the drag them over to the points. When he got to the points he would increase the pressure and pull up slightly while barely moving his head. This lifted by boob right out of the half cup, and with the sharp edges of his teeth barely moving on my nipple it hurt a little bit, but at the same time it felt great and I wanted him to do it some more. I was just just enjoying the shit out of this, when Carl stopped and said, "Oh yeah do it!" So I figured that maybe I ought to open my eyes and see what Karen was doing. Carl was bent over some so that he could get to my Boobs, and Karen was behind him, apparently rimming his asshole. Carl moved me around to where I was right in from of the couch and then pushed for me to sit down. As I sat he moved me to the front edge, knelt between my legs, tossed them over his shoulders and dove in to start eating my pussy while playing with my Boobs with his hands. With him bent over like that, Karen had full access to his ass and appeared to really start working it over. It seemed to me that she had a definate fetish for asses after the way she had been working on mine earlier and now on Carls, but them again, I knew it felt good so whjo was I to complain. Carl was quite good at being able to find the good places to get my motor running with that tongue of his, but what I really wanted was to feel that cock sliding in balls deep in my pussy. If he had been as good at eating pussy as Rich or Mom, I might have wanted him to bring me off that way first, but as it was I just wanted to get fucked! So I asked him to move up and fuck me. As he started to move, Karen said she had a better idea; why didn't he lay down on his back, I could climb on, and she would help us both get off. I'm not usually one to say no to something new, and I wasn't sure this was even going to be new, so I went along. Carl laid down and Karen held his dick straight up in the air for me. I got my feet on each side of him and slowly sank down on that hard, hot hunk of meat. I really felt nice! I got all of it in finally and just squatted there grinding my pussy around on it so it could stir my juices up even more. Then I moved my knees down and started to slid up and down on Carls cock. Very Nice! Karen was twisting my one nipple with one hand, and I could feel her massaging Carls balls every time that my pusssy gobbled all the meat back in. After a bit, Karen let go of my nipple and moved to straight behind me, where she could start rimming my asshole again. About this same time Carl grabbed my ass and just held me still while rocking his hips to slid that great cock in out of me. About that same time I heard the buzz of Karen's vibrator again and realized that I could feel it through Carl's cock! I didn't know it at the time but she had slid it up Carl's ass when she moved, that was why he started to slam his dick into me so hard, and the vibrations traveled through his dick to give me some extra sensations on my joy buzzer. Wild to say the least! I came almost as soon as I felt the vibrations, and then about a minute later Carl drilled that dick home and held it there. I could feel his cock pulsing and his cum squirting into my pussy. That along with the extra sensation of his pubic bone pressed against my clit, brought me off again. As I could feel Carl's cock softening, I decided to give it some mouth to cock recessitation. It had felt good, but I wanted more of it and I needed to get it hard again if I was going to ride it again. As I moved down to be able to suck that cock back into life, I felt a large glob of cum drool out of my pussy and start to run down my leg. As I was starting to move my hand down to catch it and bring it to my mouth, I felt Karens lips against the inside of my thigh and she just sucked it right into her mouth and then moved over to get the rest of it out of my pussy. She was trying so hard to get her tongue all the way into my love hole that I wanted to really get into getting that cock hard again. After a few minutes of working Carl back into standing up straight, Carl moved up onto the edge of the couch and said for me to eat Karen while he fucked her. I think I would have prefered for him to fuck me again, but I shouldn't be selfish. What happen next really blew my mind! I had wondered how I was going to eat Karen while he fucked her, unless he wanted me to eat her ass, which I would have done; But Karen turned around straddled him with her back to him. And then guided his cock to her asshole and just slid it all the way in! I said, "Holy shit! Doesn't that hurt?" and Karen answered, "No it feels wonderful! The only thing that feels better is being double fucked!" I watched Carl's cock sliding in and out of Karen's ass for a few minutes and Karen started moaning and playing with her joy buzzer. She was saying over and over, "Yes fuck my ass, fuck it hard! Eat me, Finger fuck me. Anything, just make me cum." The pussy juice was running out of Karen's pussy, so I figured that I might as well help her out some and dove in to start flicking her clit with my tongue and nipping at her pussy lips and clit with my teeth. While I was in the midst of enjoying myself there, I felt someone behind me. I looked around and there was a fairly good looking guy there, nude, with a quite nice hard dick. I immediately assumed it to be Karen's other brother Kevin. He moved up and started to press his dick angainst my asshole. I said, "No, my pussy!", and reached back to put him where I wanted him. His response was, "SHIT!" and then slammed that dick in. I must say he really wasn't very good at this, and certainly didn't care about what he was doing affected anyone else. He just stayed still, used the grip he had on my hip bones to jerk me back and forth on his cock. It might have been great for him, but I definately didn't enjoy it. Christ, I felt like I was a piece of warm, wet meat that he was using to beat off in! I was just about to tell him to either ease up or fuck off, when he pulled out of me, grabbed my hair to pull me around to his dick and said, "Suck it bitch!" I told him, "Fuck off! I'm not a bitch, and I'll bite it off before I suck it!" So he answered with, "Fuck you!", and moved over and started to fuck Karen in the pussy. Karen started screaming, "Oh God YES! Fuck me guys, blast me with your loads! I'm Cumming! Yes, Cum in my ass! Yes, Yes, I'm Cumming again! Come on, hump me Kevin, hose my snatch! Yes, that's it! Cum with me! Yes! Oh God, Yes!" and then a shreek as she came again and everybody stopped moving. I must admit that Karen definately liked having a hard dick sliding into her asshole, and that while I was watching Carl fucking her ass, I was thinking that maybe with as good as it felt when someone was eating my ass, or when someone had a finger there, or as good as Karen's vibrator had felt; Maybe I would try it myself. However, the attitude that Kevin had shown had turned me off so much that I decided that I was just going to go home. I went back upstairs to Karen's room and was putting my clothes back on when Karen came in and said, "Are you leaving?" I answered, "Yes, Kevin's an asshole, and I don't think I want to be around him." Karen said, "It's not so much that he's an asshole, which he can be, but that he wanted to fuck your ass and you wouldn't let him. I hardly ever let him up my ass because he's so rough and when we sandwich fuck I always give Carl my ass cause he's so gentle." I looked at her and said, "This is nuts, your used to getting fucked in the ass and you won't let Kevin because he's to rough; but you expect me to let him at my virgin asshole? How crazy do you think I am?" and she left. When I finished dressing and was starting to leave, Carl caught up to me and told me that he was sorry that Kevin was such an asshole, could I at least let him drive me home. I told him that I had driven over there in my own car, so I didn't need a ride, but I really appreciated the offer as I kind of liked him. He told me that in that case, why didn't I let him take me out to a casual dinner where we could try to get to know each other better. No strings, no requirements, and I could leave any time I wanted. I figured why not and told him that he probably ought to bring his own car as I most likely wouldn't be comming back here. We went to a place he knew called the "Fireside Inn", nice atmosphere, good food, and we ended up spending hours there talking. We had started talking about our life's goals, what I inteded to do when I got out of school in June, etc. Although Carl was a year older than me, we found that we had a lot in common, when Carl found out that I wanted to go to college for a Biology Major, we found a lot to talk about as he intended to major in Animal Husbandry and minor in Biology. This conversation went until we were both tired of drinking coffee, and at Carl's invitation I took my car home and then joined him in his to go out dancing. I enjoy fast dancing, but that night I found myself sitting and talking to Carl during the fast dances and then dancing any and all slow dances. I really liked the way that I could just move tight against him and feel his dick start to grow. It got so that as soon as we got on the dance floor I'd put my arms around his neck and start grinding my pussy on him, Carl would cup the cheeks of my ass and help in the grinding. I'm not sure which of us was enjoying it more. During one of the fast dances, where we were setting out and talking, Carl said that the more the night went on, the more that he was getting pissed at Kevin. He had really liked it when we had gotten it on earlier and wished that we could again. The problem as he saw it was; that he wouldn't suggest going back to his house because of Kevin; with my living with my Mom, my house was out of the question; with him being a college student, he couldn't afford a motel room for a few hours; and getting it on in a car was to juvinile, let alone next to impossible in his Escort. I told him that the only thing wrong with his thoughts was that he didn't know my mother and the relationship that we had. I had been thinking about inviting him home, and seeing as no one at his house would be upset if he didn't get home, keeping him there for the night. That settled, we headed off to my house. With a few of the twists and turns that fate dealt during the rest of that night, I'll save what went on for the next chapter.
