My Virgin Sister 9

"For the next two minute sucking session, you're going to lick your pussy juice off my cock," I whisper to Lisa. "Here's a sample taste," I say, pushing my pussy-soaked tongue deep inside her mouth. It is taking everything I have to hold still and not pump my cock in and out of her tight, over-heated pussy as she sucks on my tongue. Ever since the day she first licked my fingers, after I finger-fucked her, Lisa has loved the taste of her own juices. She likes kissing me after I've eaten her, and she's more than willing to suck me off, after I've fucked her. I know this is an additional turn on and will tease her even more.

"Oh Jack!" she begs. "Don't pull your cock out. Fuck me with it! My pussy feels good, doesn't it? It's burning, Jack. Just fuck me! I'll suck the juices off after, you know I will."

The look on her face, as she pleads, almost make me change my mind, but I want to tease her just a little more. I lift my weight off of her and she starts humping my cock, as I pull it out of her pussy. I slide up her body, slip my pussy soaked cock between her lips and start pumping in and out, fucking her mouth as she sucks the juices off. It doesn't take two minutes for me to start cumming. Lisa keeps sucking and swallowing, as my cock jerks several loads of cum into her warm mouth. She licks me clean, swallowing the mixture of my cum and her juices, and I decide it's time to take care of her burning snatch.

She bucks her ass up and pulls at her bindings, as I eat her pussy, suck her clit and finger fuck her through three orgasms. As she lay there, trembling from her third orgasm, I slip my fully recovered cock inside her, and fuck her to orgasm number four, while she sucks the pussy juice from my tongue. She is still panting and shivering, when I untie her hands and feet, and hold her body against mine.

"Oh my god, Jack!" she says, trying to catch her breath. "That was awesome! I can't believe what you did to me! You know me so well, Jack," she says, in a rapid-fire staccato. "You were amazing when you wouldn't even answer me. You just kept teasing and teasing. I was so hot and I couldn't do a damn thing, not even touch myself. And then, when you made me suck my own juices off your cock and then suck them off your tongue, while you fucked me! I've never cum so hard, Jack." This is something Lisa says on a regular basis. Every time she researches a new and creative twist to our lovemaking, she comes harder and harder. I wonder what's next. I also wonder why the taste of her own pussy juice turns her on so much. I might have to research that.

Mondays are always the most intense days for us. We suck and fuck all we want on weekdays, before Mom comes home, but on the weekends we hardly ever get a chance. We might grope each other and steal a kiss or cop a feel, but we are never alone long enough to get each other off. By Monday afternoon we are all over each other as soon as we get inside the front door. This leads to a lot of creative lovemaking; in the living room, the hallway or the kitchen, before we finally make it to the bedroom and fuck and suck each other's brains out.

We still fuck in the shower regularly but we also love fucking in the pool. I like to lean back against the side of the pool and stretch my legs out in the water, while Lisa, with just her swimsuit top on, straddles my cock, sucking it deep inside her tight, young pussy. It's hard to describe the sensation of being surrounded by cool water, while my cock is buried deep inside my sister's flaming, hot pussy. It's while fucking in the pool one day that we almost get caught. It's also the day that I first become infatuated with my mother's sexy body.

It's a Saturday, so we wouldn't normally be able to do anything, but Lisa is horny as hell and won't leave me alone. It's her idea for us to go swimming, and fuck in the pool, while Mom is busy doing laundry and watching TV. I tell her it's too risky but she keeps teasing me, touching my cock and rubbing her tits against me all day. Around 2 o'clock, Mom decides to take a nap. That's when I give in. We change into our swimsuits and rush out to the pool.

As soon as we hit the water, Lisa takes off her swimsuit bottom, swims over to me and pulls my suit down. My suit is hooked around one ankle, as I put my arms up on the side of the decking, and Lisa impales herself on my already rigid cock. Her face is about a foot from mine, as she furiously bounces up and down on my cock, making waves across the swimming pool.

"How's the water?" Mom asks, sticking her head out of the sliding glass door.

"Great!" Lisa answers. She stops bouncing, but keeps my cock buried deep inside her tight, wet pussy.

"The temperature is perfect and the sun isn't too hot today." I'm impressed. She's carrying on a conversation with Mom, while her pussy muscles continue to milk my cock. She's acting like nothing is going on while I, on the other hand, am freaking out about getting caught.

"Good, I couldn't sleep so I thought I might join you two for a swim," Mom says. "I'll get my suit on and be right out."

"Great, Mom!" Lisa shouts. "Wear that sexy new pink swimsuit you bought. I haven't seen you in it."

"Okay." She closes the door and Lisa starts bouncing up and down like a mad woman.

"Are you crazy?" I ask. "Mom's going to be out here in a minute. We have to stop and get our suits back on." I can't believe she wants to keep fucking with Mom coming out.

"Just a few more minutes, Jack," she says, panting. "It'll take Mom a while to get changed. I'm so close. It won't take long."

She is watching the door, bouncing on my cock and grinding her clit against me. Just as she starts to cum, I hear the sliding glass door open. She pushes down hard, clamping her hot, quivering pussy around my cock. As Mom is stepping through the sliding glass door, Lisa quickly jumps off my cock and swims away from me. We both struggle to get our swimsuits back on, before Mom gets to the pool.

Lisa is smiling at me and treading water in the deep end of the pool. Mom is walking down the steps, in the shallow end, near me. Mom keeps herself in shape and looks about ten years younger than her 37 years. She's wearing a light pink two-piece swimsuit that shows off her tan, well-toned body. As I watch her get in the pool, it's easy to see where Lisa gets her sexy shape. Mom's flat stomach, the curves of her ass and her shapely legs all remind me of Lisa. Her breasts are much larger and a lot more of her tits are visible before they disappear behind the small triangles of her swimsuit top.

This suit must be smaller than her others because there is a thin white strip of skin between her swimsuit top and where her tan begins. Her swimsuit bottom is just a small V shaped piece of material covering her pussy with strings tied on the sides that connect to the material covering her firm, round ass. I'm not sure why I'm suddenly noticing all this about our mom. Maybe it's because my sister has gotten herself off and left me with a raging hard-on.

Mom reaches the bottom of the steps and plunges into the cool water up to her neck. She shivers and jumps back up to a standing position, yelling that it's cold. I watch her ample tits bounce up and down and can see the effect the cool water is having on her nipples. Her erect nipples appear to be embossed on her swimsuit top, as she stands there in the waist deep water. She sees me staring at her tits and casually turns away, slipping back into the water up to her shoulders. She turns back and I notice her check out the bulge in my swimsuit, before starting to swim to the deep end. It looks like she's smiling as she swims away. Could it be? Is my Mom pleased that I'm sporting a hard-on, while checking out her tits. This could be interesting.

"Let's play monkey in the middle, "I yell at Lisa and my Mom.

My sister swims over to me, and whispers in my ear. "As long as it's your monkey in my middle." She laughs, and then more loudly she says, "Okay, but Mom's in the middle!"

It's a keep-away game with one person in the middle and the other two throwing a ball back and forth. Mom's in the middle and keeps jumping for the ball as Lisa and I keep throwing it around her and over her head. We're laughing and playing and dunking each other like a bunch of kids. Except, I can't keep my eyes off my Mom's tits with her thick, protruding nipple, pushing out the swimsuit material. I have a clear view of them, bouncing hypnotically, while she's jumping up to block the ball. When she's facing Lisa I just stare at the curves of her bikini-covered ass.

My cock has stayed hard the whole time and I catch Mom subtly eyeing it. Mom's getting more aggressive in trying to get the ball and I make sure there is a lot of skin contact, as we dive and wrestle for it. At one point, with Mom facing Lisa, I reach my hands around her waist and lift her up, pulling her back in the water on top of me. She's laughing as we fall backwards, and I manage to push my hard cock against her ass, as we tumble through the water. My hands slip up and "accidentally" brush against her tits as we both come up sputtering.

"You're cheating, Jack," she says, still laughing. "I'm not playing if you're going to cheat." She starts walking toward the steps. "Actually, I've had enough rough housing for one day. You guys are a lot younger than I am." She sits on the steps and I swim over to Lisa.

"I'll race you to the other end!" I say, winking at her. She immediately dives under water and starts swimming. We come up at the other end of the pool at about the same time and I take the opportunity to ask Lisa if she's noticed Mom acting funny.

"I've only noticed you acting funny, staring at Mom and constantly trying to touch her. What are you doing, Jack?" she whispers. "You aren't thinking of expanding your incestuous conquests are you?" she asks, smiling.

"Don't be silly," I answer, looking back at Mom sitting on the steps, leaning back with her eyes closed. Then I explain to Lisa about how Mom reacted to me staring at her tits and how I'm pretty sure she was smiling and looking at my bulge. "Did you notice how hard her nipples have been all day and how she keeps looking at my cock?"

"Well, dad's been gone over two months, Jack. How would you like to go two months without fucking? I know I wouldn't like it." As she's saying this, she reaches down and starts stroking my cock through my swimsuit. "You are one horny guy, Jack. Is that because of Mom's nipples?"

"No! It's because somebody had to get fucked in the pool and then she swam away before somebody else got to shoot his load. But now that you mention it, I've stayed hard all day staring at Mom's sexy body, watching her tits bounce and seeing the outline of her hard nipples through her swimsuit. God, am I a pervert?"
