Life changed dramatically for me thanks to swimming in my family pool.
My twin brother, Kai and I were doing what we've always done - mess around and play games. We're both blonde and blue-eyed (from Swedish descent on my mom's side). From day one we've been very close, as twins often are. We're both very athletic (Kai plays football and I'm into tennis).
On the physical side we are quite different. Kai is 6'1", 180 and really muscular (that's why he's a running back). That's why he usually had an advantage over me in our pool games.
I'm 5'6", 110 with long legs and honey blonde hair that comes down to my shoulder blades. Despite being a bit petite, I've grown large breasts. I have to wear a pretty strong sports bra when I play tennis or my boobs bounce around a lot. Both of us have light blonde bushes. How do I know what Kai looks like? Well, that's part of my story!
And, by the way, we were both virgins at the beginning of this series of events. Neither one of us have had had boyfriends or girlfriends. When your best friend is also your sibling it's harder to need those kind if relationships.
We live with our mom (both of us are seniors in high school) in a pretty exclusive area of Bel Air, California. Our house is pretty incredible, with a tennis court and a pool and hot tub. My mom has done really well in the tech world, especially for a woman. She's definitely my greatest role model, although her job forces her to spend time out of town.
Kai and I each have our own rooms with an adjoining bathroom we share.
Like I said, Kai and I are super close. Up until recently it's been very plutonic. We fool around in the pool - taking turns dunking each other and I get on Kai's shoulders and he tries to throw me off - stuff like that.
One day when we were chasing each other around in the pool. I was aiming for his arm as I went over his shoulder but he moved suddenly and my hand closed on his cock instead.
"Watch it, Kayla!" he said.
I said I was sorry but in reality I was pretty shocked at just how big Kai's dick was. I tried to dismiss the strange feeling I got from the encounter, but could not get it out of my mind.
I'd never thought about penises before. Touching Kai's over his bathing suit got me curious. I got on my phone and looked at dick pics for a while. I loved the smooth sides of the shaft and the mushroom-like head. Some had visible blood vessels along the sides. I especially loved them when they got erect. Those vessels would bulge and the whole thing would swell up. They were so hard and tall and beautiful.
I tried to imagine what Kai's looked like under his suit. It felt large and squishy when I touched it. What happened when it got hard, I wondered?
Over the next few days I caught myself looking at Kai's crotch, hopefully when he would't notice. I was having strange feelings between my legs when I pictured Kai's hard cock. Great feelings. What would it feel like to touch, to taste? But this was my brother, I thought. I'm not supposed to feel this way. I just couldn't seem to help myself! I imagined myself touching his smooth hard dick, putting it in my mouth, in my pussy. What was wrong with me? The feelings were incredible and terrible.
One day, after a session with Julie, our family tennis instructor (who is a redhead and quite stunningly beautiful) we laid out by the pool. I had on my tennis skirt and bottoms and Kai a t-shirt and loose fitting shorts. I arranged the chaise lounges facing opposite each other slightly offset. It gave me a great close-up view of Kai's shorts and, he, apparently, my crotch.
I laid there on my back, head to the side, staring at Kai's shorts while trying not to he too obvious. I closed my eyes almost all the way pretending to sleep when I was actually looking up Kai's leg. Was it my imagination or was Kai's dick actually growing? His shorts began to bulge and a shape pushed up towards his waist. I started having a tingly feeling between my legs.
I was just becoming aware of a trickle of wetness on my inner thigh when Kai said, "Are you sweating or something?"
Startled, I said, "What? What are you talking about?"
Kai motioned to the space between my legs.
"You're dripping."
I was instantly embarrassed, closed my legs and got up.
"It's not sweat!" I said as I rushed inside, into my room, and closed the door and slid the bathroom door closed.
I sat on my bed but realized the embarrassment was not my main feeling. It was excitement, sexual excitement. I was getting majorly turned on by seeing my brother's cock get hard - by causing his dick to get hard.
I looked between my legs and saw my bottoms were completely soaked. I lifted up my skirt and peered at my pussy under my panties. Along the slit of my labia there was a rivulet of clear liquid. I watched as a drip started to escape. I reached in and caught the drop and without thinking put it my mouth. It tasted sweet and a bit salty, but good. I'd just tasted my own pussy juice and loved it!
I pulled off my skirt, bottoms, and panties. I wanted to taste again so I pushed my index finger into my slit. It was covered in juice and as my finger barely touched the tip of my clitoris, I practically jumped off of the bed with the most incredible feeling. Wow!
I felt something in my nipples as well so I pulled off my top. I could see two dots of moisture coming through my sports bra. I pulled it over my head and saw my nipples also dripping with liquid.
I caught a drop with my finger and licked it off. It tasted the same as my pussy juice but a little more tangy. I squeezed my nipples to see if more would come out and it sent a tingly sensation radiating out from my tit.
I laid back, pushed myself up to the head of the bed and opened my legs wide. with one hand I touched and squeezed my nipples and with the other I caressed my now swollen clit.
I closed my eyes and as my mind returned to Kai's cock, I pictured it swelling and growing hard, pushing out of his shorts and standing up straight. My pelvis began to move up and down and the movements of my fingers back and forth over my clit quickened. My breathing got faster too and I found myself moaning.
I pictured myself putting Kai into my mouth and I felt a fresh gushing of pussy juice. As I thought about what it would be like for his huge cock to enter me, I slid my fingers down my slit and slipped two of them into my vagina, using my palm to press on my clit.
I suddenly felt myself crest in the most amazing way. My pelvis arched upward, toes curled and I cried out as a sharp sudden burst of pleasure enveloped me and carried me away in wave after wave after wave. So much juice came out that it left my hand sopping wet.
I'd just experienced my very first orgasm, and it was from fantasizing about my brother's cock!
I laid there, slowly coming down from the high. I'd been very naive about sexual pleasure, but no more. I wanted it, I needed it, and I craved it. I wanted to fuck my brother.
This was wrong! A sister shouldn't feel this way about her brother, should she?
A bit of the embarrassment returned. What had I done? Yet, he had gotten hard, hadn't he? I started to worry about Kai's reaction so I got dressed and went looking for him but he was nowhere to be found.
Later, when I saw him at dinner, he acted like nothing had happened. It was the same the next day too. But it sort of felt like he was avoiding me.
I could not stop thinking about him and his cock. I wanted him in the worst way.
The next day was Saturday and Mom and I had planned to go swimsuit shopping. Kai was still in his room when we left, so Mom left him a note telling him what we were doing.
I was starting to feel sexy for the first time, so I looked for some barely-there suits that covered very little of my 32D and nothing on my rear - just a string going from my waist down my crack. Mom didn't chide me for my choice and actually picked out a suit for herself that didn't cover much more.
As we changed together, I noticed Mom checking me out.
"We haven't done this in a while, have we?" she said. "You've grown into quite a woman!"
Mom had no clothes on at the moment. She was really beautiful with her huge, firm breasts that barely sagged, a cropped blonde bush and a very toned body. I was envious of her good looks. After my experience the day before, I wondered if she masturbated very often or at all.
"Thank you!" I said. "I get my good looks from you, you know."
As I put on the top I wondered aloud, "The fabric is pretty thin. Do you think my nipples will show through?"
I asked that because I actually wanted them to.
"You can tell by tweaking them a little. Like this," she said as she squeezed both her nipples."
I noticed they instantly perked up.
"Now help me into my top," she said.
I pulled the suit top around her breasts and fastened it in the back, tying the strings behind her neck.
"See?" she said, turning around, "they do show a little. But that's okay," she said, winking. "Now it's your turn," Mom said as she grabbed my suit top. "Squeeze yours like I did."
As I touched my nipples I felt a tingling sensation and my tits popped upright.
"That's right," Mom said. "Boy, your nipples are sure sensitive like mine."
Mom reached around me to pull on my top. She grazed the sides of my boobs as she did it. It felt good but, at the time, I chocked it up to my feelings for Kai. Why was I so turned on all the time?
