My Virgin Sister 12

Mom is unbuttoning her blouse and slipping it off her shoulders, while she kicks off her shoes. She's wearing a white bra, with a front fastener, that she unhooks with one hand. Her ample tits bounce loose, as she shrugs the straps off her shoulders, tossing her bra on the bed. Lisa and I just stare open-mouthed at our first sight of our mom's gorgeous tits. Her tan stops halfway down her large, round breasts creating a stark contrast with the fleshy white orbs that surround her two-inch wide areolas. Her dime sized nipples stick out about 1/4 inch in the center of her smooth areolas.

"God, she has great tits, doesn't she?" whispers Lisa excitedly. "It makes me want to suck on her nipples?" My sister never fails to amaze me.

I move behind Lisa, watching Mom over her shoulder.

"I can picture each of us sucking a nipple at the same time, like we must have done when we were babies," I whisper in her ear.

I wrap my arms around Lisa's bare midriff, rubbing my cock up and down against her swimsuit-covered ass. I notice Lisa glancing down at her own chest as we watch Mom continue to undress.

"I can also picture Mom and I sucking your sexy nipples, Sis." I slide my right hand inside her swimsuit bottom, rubbing one finger up and down her moist slit. With my other hand I pinch one of her nipples through her swimsuit top.

"Mmmmm, oh look!" Lisa directs me back to the scene in Mom's room.

Mom unzips her skirt and wiggles out of it, shaking her tits back and forth, while the skirt falls to the floor. Slipping her thumbs inside the waistband of her pantyhose, she pulls them down over her hips. A dark patch of pubic hair is visible through her white thong panties.

"She's wearing a thong! Can you believe Mom looks so hot?" Lisa breathes as she rubs her pussy up and down against my finger. She's squirming around and I can't believe how hot she's getting seeing our mom naked.

Mom sits on the end of the bed to roll her pantyhose the rest of the way down. As she leans forward, we have a great side view of her tits, hanging down over her thighs. With her pantyhose off, Mom stands up, turns her back to us and rolls her thong over the curves of her hips. We are spellbound as the thin strip of material pulls loose from between Mom's firm, round ass cheeks. There is not a hint of sag in her ass and we catch a quick glimpse of her pussy lips before she straightens up, letting her thong fall to the floor.

"Look at that!" hushes Lisa, pointing toward the mirrored closets. "Look at how neat her pubic hair is trimmed." She's right. Mom has a neatly trimmed triangle of dark hair leading down toward her pussy lips, which are clearly visible between her legs. As she stands completely naked before us, my eyes dart back and forth between her pussy, which I can see in the mirror, and her ass, which is facing us. I'm trying to take it all in, as she pulls her swimsuit out of a dresser drawer. She bends over to slip her legs into the bottoms and again my eyes are torn between her beautiful, round ass and her firm, melon sized tits, visible in the mirror. I stare at her tits, spellbound by the light rose-colored areolas surrounding her thick nipples. I watch them jiggle slightly as she stands up, pulling her swimsuit bottom up over her ass and adjusting the ties on the side.

"There's no hair around her pussy lips, Jack. Did you see that when she bent over? She shaves around them." Lisa is bouncing up and down excitedly slipping my finger in and out of her tight, wet pussy. I switch my left hand to her other tit, pinching her now erect nipple through her top.

I watch Mom put her swimsuit top on exactly like I've watched Lisa do so many times. Fastening it in front, and then turning it around so the fastener is in the back. She slips her arms into the straps and adjusts the front triangles over her large white tits. She checks herself in the mirror and heads out the door. Lisa and I make a mad dash for the pool.

"God that was hot, Jack!" Lisa says before Mom gets outside. "I'm soaking wet and I don't mean from the pool water." We're standing in the pool, Lisa's nipples are embossed on her swimsuit top and I'm sporting a raging hard-on. We act like nothing's wrong as Mom walks out, closing the sliding glass door behind her.

"Hey kids! No monkey in the middle today, okay? I've worked all day and I just want to relax in the pool," Mom says, putting her towel down on one of the lounge chairs and heading toward the pool.

"Okay, no problem," I say, as I watch my sexy mother walk down the steps of the pool. Seeing her tits jiggle, as she descends the steps, I can picture her nipples surrounded by smooth, white skin under her swimsuit top. My cock reacts accordingly and I turn away so it's not obvious. Mom plunges into the water and swims a couple of laps, her graceful body gliding the length of the pool.

Lisa swims over to me and whispers in my ear. "Let's put on a show for Mom. Don't hide your bulge from her, tent boy." With that she climbs up my body and dunks me under water. As I come up for air, Lisa jumps on my back, wrapping her legs around my waist. I loop my arms under her legs and give her a piggyback ride around the shallow end of the pool.

"Giddy up!" Lisa laughs, bucking against my back like a bronco rider. It's very innocent looking, but Lisa is humping her pussy against the small of my back as I splash around the pool. The front of my swimsuit is bulging just under the surface of the water and I see Mom staring at it, as Lisa rides my back. I dip down into the water and Lisa shifts from my back, up to my shoulders. I stand up again, with Lisa's legs wrapped over my shoulders, and I grab her knees so she won't fall. She is still laughing as she starts bucking again, humping her pussy against the back of my head. I tilt my head back making harder contact with her mound and look up to see her nipples pushing out her swimsuit top.

Mom is sitting on the steps, taking all this in, as I move toward her. When I'm about two feet from her and she can't miss seeing my bulge, I arch my back, thrusting my hips toward her and throw Lisa backwards into the water. I smile at Mom, and she tries not to stare at my bulge, as I turn and swim toward Lisa. I grab her by the waist and we start wrestling in the water. A few minutes later, Lisa announces that she's had enough and climbs out of the pool. She adjusts a lounge chair until it's flat, spreads her towel on it and lies down on her stomach.

"You're going to get burned, Sis," I yell to her. "You should put some suntan lotion on your back."

"Thanks, Jack," Lisa yells to me. "Mom, would you mind putting lotion on my back?" Lisa asks innocently.

"Not at all, honey." Mom grabs the lotion and Lisa scoots over to give Mom room to sit on the edge of the lounge chair. Mom squirts lotion on her hands and begins rubbing it on Lisa's back and shoulders around her swimsuit strap.

"Undo the strap, will you Mom?" Lisa asks. "I don't need a tan line across my back." Mom flips open the fastener with one hand, lays the straps next to Lisa's sides and continues rubbing the lotion on her bare back. Meanwhile, I've gotten out of the pool and I'm standing behind Mom. I reach over her shoulder for the bottle of lotion and squirt some onto my hands.

"You need some too, Mom," I say, as I begin rubbing the lotion on her shoulders and back. "You don't want to get burned, either." I look over Mom's shoulder at Lisa who looks naked except for her cute, little, swimsuit-covered ass. She's smiling and encouraging Mom.

"Mmmm. That feel's good, Mom," Lisa says dreamily. "You give a great back massage." Mom doesn't respond. I'm not sure what she's thinking about this daisy chain of back massaging, but it's really turning me on. My swimsuit bottoms are tenting out, and my hard cock is only a few inches from Mom's head, as I stand behind her, massaging suntan lotion on her back.

"I think that's enough," Mom says giving Lisa's ass cheek a light smack. "You won't burn now." She turns to get up, bumps her cheek against my swimsuit-covered bulge and freezes. Her face turns bright red and her eyes stare right at my cock, but before either of us can react, Lisa interrupts us.

"Wait Mom, what about the back of my legs. Please put lotion on my legs too or they'll burn." Lisa spreads her legs apart on the towel covered lounge chair, and Mom turns around reaching for the suntan lotion. She rubs her lotion-soaked hands together and starts rubbing up and down on Lisa's calf. I put my hands back on Mom's shoulders and start rubbing lotion around, but she's not going to let me continue.

"Here make yourself useful," she says, handing me the suntan lotion. "Put some lotion on your sister's other leg."

I move around the other side of the lounge chair, kneel down on the deck and start rubbing lotion on Lisa's other leg. I watch Mom's tits gently swinging back and forth as she rubs up and down Lisa's leg. Her nipples are erect and make a clear outline on her swimsuit top. Mom catches me looking and glances down at her own breasts and then over at my bulge. Lisa has moved her legs farther apart and I slide my hand all the way up the inside of her leg, brushing against her bikini covered bottom. Watching me, Mom does the same thing on her other leg. Mom is still staring at the tent my cock is making in my swimsuit.

"Mmm. You guys are a good team," Lisa says, "you could market this."

Abruptly, Mom stands up, wiping her hands on her thighs. "Okay, I think you'll do. I'm going in the house. I've had a long day. I'll see you guys in a little while," Mom says all in one breath. Her face is flush and her nipples are hard, as she scurries across the patio and into the house.
