When I was a teenager I read a lot about sex. I was very curious about boys and wanted to know everything about them; the way they thought, about their bodies and what got them turned on.

One thing I have learned growing up is that books don't really tell you all that much about "how" to do things. Life experience is what really counts, and that's what brings me to my story...

The person who taught me the most about sex was a very close friend who lived in my apartment building. Her name was Donna. She and her husband Andy were real, true-life swingers before I met them.

It wasn't long after they moved into my building before Donna sought me out as a kindred soul. Being highly sexed myself, I was aroused by the stories Donna told about their experiences in the big city.

My first erotic adventure started out with just Donna and myself, but turned into something that changed the way I regarded sex all together. Until then I'd only had sex with three people, and they'd all been male.

My first time was with a boy in high school. I was a junior and he was a senior, and at the time I thought he was a god. It's funny how innocent one can be.

The second time I had sex was with a freshman, when I was a senior. He was beautiful and he easily seduced me. We were screwing within a week of meeting in South American Policy Club. He was from Chile and a real Latin lover type, but unfortunately he also brought that macho South American thing with him. We broke up when I began finding it hard to breathe with him always looking over my shoulder.

The last lover I had was Alan, my current boyfriend. He's seven years older than me and a hunk of a guy, very much an outdoorsman, with muscles that are so smooth and hard I can't keep my hands off them. I just love to feel up his body and it's great fun wrestling around in bed with him.

That brings me back to the reason for writing this story. Even though Alan and I had great sex all the time - and I define great sex as "rip-roaring forget everything except each other's bodies" - I had a problem; I wasn't very good at giving head. I didn't even realize it till I met Donna and Andy; I guess I thought men couldn't "get off" on oral sex because none of mine ever had.

Well, about two months after Donna and Andy moved into my apartment building I had my first real experience with "out of the ordinary" sex, when Donna seduced me. This may sound perverted and shocking to most people, but looking back I have no regrets. Donna was a beautiful woman - I'd say in her mid-30s, I was 20 years old then - and she was obviously much more knowledgeable than me about everything pertaining to sex.

We were in my apartment, browsing the swinger sites on the Internet; we'd got used to doing this because Donna liked to check out her old haunts and I liked to watch, when one thing led to another, and she had her hands on my thighs. Then the next thing I knew we were on my bed with her face between my legs.

To say I was surprised by this turn of events is putting it mildly. Though Donna sometimes had aroused me with her stories, I'd always directed my fantasies toward the men she'd had sex with. When she talked about her female partners I was always a little embarrassed. But my boyfriend had been away for almost a week by then and for some reason I hadn't masturbated during all that time, so when Donna started feeling me up I just went with it.

That's not to say I wasn't of two minds about it, but at the same time I was so aroused there was no way I was going to stop her, I needed to see what she had in store for me. It was wonderfully sexy to have another woman seduce me like that. She was so urgent about her need for me and she gave me feelings that up until then I'd only gotten from my boyfriends.

Donna knew all the right buttons to push and exactly how long to push them. She quickly drove me into a sexual frenzy like nothing I'd experienced before, not even with Alan.

I think I almost blacked out during that first time, the sensations that Donna caused me to feel were so intense that my whole body jerked uncontrollably as wave after wave of pure ecstasy jolted through every nerve ending I possessed.

Afterwards, as I lay in her arms, breathing heavily, recovering from the best orgasm of my life, that's when the subject came up. She was cradling me from behind, spooning me with her body and idly fingering one of my nipples, while we quietly talked about what we'd just done.

Donna was describing the techniques that she'd used on me when the subject of blowjobs crept into the conversation. She asked if I liked giving Alan blowjobs, and if doing it made me horny.

Normally I'd have been embarrassed to talk to another woman about oral sex with my boyfriend, but after what we'd just shared I felt comfortable talking to her about virtually anything.

I said I liked the way Alan responded to my oral efforts; that I loved to see him writhing around under me; that I always felt so in control; and that we always had great sex afterwards. Then Donna asked me if I liked the taste of his cum.

Without giving the question much thought, I replied that he'd never actually cum in my mouth. Donna seemed surprised and as we talked some more about it she made it plain that a good blowjob "always" ended with the man cumming. She went on to insist that if he didn't cum, then it wasn't a good blowjob.

I was totally blown away by this. I believed Donna knew what she was talking about and I was suddenly worried about what Alan might really think of my oral talents.

Then and there I confided my worry to Donna. I love my man and want to be the best I can be for him. Until then I had thought I was, but I'd obviously been deluding myself, at least about my oral sex capability.

I sat up abruptly, pulling myself out of Donna's arms and asked her intensely if she would teach me how to give good head. I assured her I had the will to do it right, and that I'd be eternally grateful if she'd impart her knowledge to me on the subject.

Donna smiled at me and reached out to fondle my breasts, bringing back the memory of our recent sex together. I closed my eyes and enjoyed the touch of her fingers as they moved over my breasts. Then when they moved down my stomach I lay back on the bed to accept whatever she had in mind for me.

As Donna's hands roamed over me, slowly urging my body into arousal, she began describing how best to give oral sex to a man. I listened in an increasingly agitated state; I shivered in lustful delight every time she ran her hand between my legs to rub my most sensitive spot.

Even though I was grooving on Donna's handjob, I sat up in shock when she proposed that I watch her give her husband, head!

At first I was totally grossed out. Though I've always thought of myself as a potential voyeur, I'd never done anything like that, unless you count watching boys playing volleyball on the beach in their tiny swim suits, or sticking around after cheerleading practice to watch the guys exercise on the field, in their t-shirts and shorts. And doing a little fantasizing.

But this was a totally different kettle of wax. I spluttered a bit, and then asked if she was really serious; did she really mean she wanted me to watch her and Andy doing it?

Donna just smiled and then said, "Yes, I'd like that." She went on to say that she was sure Andy would enjoy it too.

After several minutes she had me convinced that I needed to watch her do it if I really wanted to learn how to give Alan good head. But I was still nervous about it, especially when Donna said I shouldn't tell Alan. She said that it would be best if I first learned how to do it and then surprise him with my new talent.

At last I agreed to do what she suggested, but was shocked when she immediately reached over to pick up the bedside phone to call Andy!

He was coming over, right now! I jumped up and collected my discarded shorts and t-shirt. Donna watched as I hurriedly dressed, all the while talking quietly on the phone to Andy. Finally she hung up the phone and rolled onto her back, still smiling at me. God, she was beautiful.

I like my body just fine, I'm happy with what I see in the mirror, but Donna... she was stunning. I'm what you might call a self-made woman. When I was small, I was a little overweight, but by the time I hit the summer after sixth grade I was tired of being pudgy. I started to run and to workout, I was determined that I was going to shape my body into something special, and when I started middle school that Fall I was a different person.

I just loved that year; all the boys were falling over themselves to be nice to me. Suddenly I wasn't just some pudgy kid in class; I was sought after by both boys and girls, I was instantly popular. I started doing all kinds of extra-curricular stuff, joining clubs and even getting a coveted spot on the Panthers cheerleading squad! I was actually invited; I didn't even have to try out!

At 30-something, Donna had the maturity and luscious lines I still lacked. As she lay on my bed, naked to my gaze, I realized she was proud to show off her body to me. And she had a lot to be proud of; she had one of those Loni Anderson type bodies, the kind most women dream about, especially if we have to be seen at the beach in a skimpy bikini.

She looked so well put together, even her pubic hair was shaved into a neat little triangle. I was suddenly embarrassed that she'd seen me naked, but I stopped worrying about that when Donna asked me to sit beside her. I didn't hesitate for a moment.

We had a new kind of relationship now. She was sort of my mentor and I trusted her. At that moment, with my body still vividly glowing from the pleasure she'd given it, I was a little in love with her. (Yes, I know it sounds strange, but you don't know Donna.)

I only resisted briefly when she reached out an arm and pulled my face down to hers. As she drew me close I had an impression of perfect tits jiggling when she flexed her arm, of wonderfully full lips slightly parted as she pulled me ever closer.

I still remember the feeling of complete liberation when our lips met that first time. I love to kiss, but until then I'd reserved my passion only for guys. I'd kissed girls before, but only as friends or family, and had never had any sexual thoughts while doing it.

This was different! These lips had just been at my pussy. These lips had just given me the most incredible orgasm of my life. I devoured them; I bit them; I sucked on them; I probed them with my tongue, pressing mine against hers, reveling in the heightened arousal that was flooding through my body.

I lay there, on top of this naked beauty, taking the aggressive role as I caressed her perfect breasts, gently kneading them in my passion. My mind was numb, my rational self abandoned to the moment, to the sensations and the signals that I received from Donna in her passive acceptance of my caresses.

Then, to my horror, I heard clapping come from behind us. My face burning bright red, I jerked away from Donna and looked up. I was unable to breathe for a moment as I looked into Andy's deep brown eyes.

Andy looks like Sam Neil's twin brother (You know; that actor from New Zealand). I'd always found him attractive and though he was almost 40 I still wondered secretly what he'd be like in bed. At that moment however, I was totally humiliated, my arousal instantly gone; the wetness at my groin that moments before had been a fire flowing from me, had cooled; leaving a feeling of guilt, not lust.

Donna moaned in disappointment when I pulled my lips away from hers. She complained that Andy had interrupted our fun and that all men were such stumblebums. Then she grumpily sat up to accept her husband's greeting.

Andy good-naturedly accepted the verbal abuse from his wife, admitting that he should have kept quiet. He pointed out though, that Donna had called him over, not the other way around.

All this time Andy was looking at me, his eyes locked onto my lips, which only a moment before had been glued to his wife's. God, how embarrassing!

Suddenly embarrassment about kissing Donna was replaced by shock when Andy pulled his polo shirt off over his head and began to unbuckle his belt. I wanted to run out of the room and involuntarily screeched, "Hey wait a minute!" I stood up ready in my confusion to abandon my own apartment.

Andy stopped. His hands were about to push his pants down over his hips. He looked questioningly at me. Then Donna reminded me why Andy had come over and that it would be difficult - if not impossible - for her to perform oral sex on him with his pants on.

I wasn't sure now that I wanted to watch this, but Andy seemed to think Donna had resolved everything with her intervention and pushed his pants and underwear down in one quick movement.

Andy's was the fourth penis I'd ever seen... well, the fourth one I'd seen hard anyway.

Despite myself, I was fascinated. It was different from the three I'd seen before; they had looked pretty much alike. Andy's however, was a good inch longer, and the mushroom head seemed more pointed and sleeker looking, it looked like a predatory heat seeking missile.
