Before I became the late 30-something wife and mother I am now, I was like many teen girls of my generation. In fact, I was a bisexual teen girl, and enjoyed having sex with people of both sexes.

On that day, I was like so many other teen girls in the late 1990s. Bisexual, constantly horny, and more than a little promiscuous. But hey, we thought we had it all figured out. TV shows and movies were telling us to go ahead and sleep with our friends, liking both boys and girls was normal. And we had figured out how to avoid HIV, our President had been telling us that getting a blowjob was not really sex, and the Surgeon General was encouraging us to masturbate.

I started my sexual life with another girl when we were both 14. It had started at a sleepover, where we did a little kissing. Then another sleepover where we did a little touching. Then after school one day when we just dropped the pretense and did a lot of touching. We both loved what we did, and neither of us feels any shame because of it. Then as I went through High School more sleepovers with other girls and more exploring. Dates with guys, then dates with guys ending in handjobs. Then dates in guys ending with blowjobs. Then on more than one occasion when I was a senior, dates with guys ending up with either my pants down around my ankles, or my skirt pulled up over my ass and getting delightfully plowed. Then I started to tone things down, realizing I did not want to be known as a slut. So with only one exception since then, I only have sex with somebody inside of a relationship.

This occurred during a summer when I had just graduated and was 18. I lived in Los Angeles, so the beach is a favorite place to go. I was short, with long hair so I tend to stand out a bit. On top of that my dark tan made me look like some kind of beach bunny.

That day, I was hanging out near the pier in Santa Monica, and started to talk with this girl. She was cute, and new to the area having just moved to California from Wyoming of all places. We quickly started to laugh and talk, and I filled her in on what we did here in LA. And of course comparing which guys we thought were cool, and which were geeks. I told her about the clubs we could go to, places to hang out, and places to shop.

I was dressed in my new dark blue bikini. It was as low-cut as my father would let me get away with, and not as low as I wanted. Marti was in a real tight red one-piece. She was taller than me (then again, who is not?), and more rounded in a very delightful way. I liked the way her bottom looked in it, but kept that to myself, not wanting to freak out my new friend. After all, I knew that LA was one of the leaders of the country, and surely some girl from the sticks in Wyoming must be very different in many ways.

We walked up and down the beach all afternoon. Talking about guys, playing in the water, playing games in the arcade, and the usual stuff. The first time she giggled and put her hand on my shoulder, I felt butterflies way down deep in my belly. I did the same in return, but was not sure if we were really flirting or not. We then spent about an hour flirting with these 2 good looking guys. They bought us lunch, and finally left when they realized that neither of us would do anything more with them on that day than talk and flirt a bit. But before they left, we both told them to look for us another day. We then laughed as we patted ourselves on the back for scoring a free lunch from the guys, and all it took was flirting.

When it was starting to get dark, so we went to the lockers to get our stuff and change back to regular clothes. I had ridden my bike there, while her mom drove her over. When we got to the shower building, there was only one change room/shower unoccupied. Marti suggested we share it, and it sounded reasonable to me. I mean, it was no different from what I did during gym at school right? Plus I was figuring at least I might be able to check out what she looked like under that red one piece.

Once inside, I stripped down, and moved under the lukewarm water. My nipples hardened, but that was strictly involuntary. They got stiffer however when I glanced out of the corner of my eye as Marti removed her suit. This girl as was as fine-looking as I suspected. Like me, she kept her pubic hair closely trimmed. And as I moved my hand down to wash the sand and salt out of my pubes and gash, I was wishing that it was her hand doing it. Or that my hand was doing that to her bush.

She moved next to me, and we brushed against each other a few times as we washed our hair and bodies. Even though it should normally take only 2 minutes or so to do this, we both lingered. I did not want to leave her so soon, and she seemed to feel the same way.

I turned my back to her to rinse my face, and I felt her hands on my back. “Let me make sure all the sand is off,” she said as she ran her hands up and down my spine, eliciting chills. After several passes, her hands were at the small of my back, and lightly caressing my side. I shivered and bit my lip to not moan at her touch. The last thing I wanted was to have my new friend think I was a perv, so I reached forward to rest my hands on the wall in front of me, and leaned forward slightly as I bit my lip. She then blew my mind when she reached around to my front, and lightly ran her fingers along the underside of my breasts.

I could not hold back the moan as Marti did this, and this seemed to be what she had been waiting for. I felt her move closer, so her chest was barely pressing against my back, and her hands grew bolder, now cupping the underside of my breasts. It was so amazingly gentle and tender, and unique in so many ways. Her hands just cupped them from the underside and gently squeezed, like she was a living half-cup bra.

I moved back to press my back against her front, feeling her large breasts press into me. As I did that Marti let her hands start to explore my breasts, and I moaned a bit louder as her fingers started to caress then play with my nipples. I was getting turned on something fierce, and could feel my pussy going from damp to wet as the excitement inside me built. I turned around, and we kissed there under the water, bellies and hips pressed firmly together as our tongues moved into each other’s mouths. Marti continued to caress my breasts and nipples, as my hands moved up and down her back. I moaned and grasped her head as she broke the kiss and ducked down, suckling on my right nipple as I cradled her head. I started to feel guilty, because I was already seeing a guy, but the lust could not be denied. As the day had worn on I realized that I had wanted this girl, and now that it was happening I was not going to deny it.
