My sisters big tits (incest brother sister)

Posted on December 1, 2008. Filed under: family sex | Tags: , , , , |

It was a game we played, my sister and I, as we sat across from each other eating our dinners in silence. It would begin with Lisa crossing then uncrossing her stocking-encased legs. I loved the sound it made and she knew it. This would go on for a while as the meal progressed.

Then, I’d drop my fork.

I’d reach down, looking under the table. My sister would have her legs slightly parted, showing her satin panty covered pussy beneath the short skirt she’d be wearing.

I’d sit up again returning my fork to my plate. This move would all be over with within a couple seconds so as not to arouse suspicion from our parents sitting at the table. Lisa would give a little fleeting smile.

This game played second fiddle to my true obsession about my older sister: her enormous tits. Her bra size was 34F. Slim and pretty with shoulder length light brown hair, and boobs that look completely out of proportion with the rest of her body. Balloons on a stick in other words, and I was completely in lust with her.

She knew I had the hots for her. Though I’d always been careful, she caught me looking just too many times. And that’s when the real fun started: her teasing me with her beautiful body.

As soon as our parents would leave, the short skirt or tight pants she’d be wearing would come off and she’d be loafing about the house in nothing more than her hugely bulging top and a pair of panties.

“Say it, Tom,” my sister said one afternoon, staring at my arousal she’d caused.

“Say what?”

“I give you a hard on. You think I’m hot. You can’t stop thinking about me. You think I’m the hottest girl in high school.”

“I.” I stammered and tried to hide the big lump in my pants with my hand.

“Say it, brother dear. Don’t be shy. I know you can’t stop thinking about my tits.” She hefted her T-shirt covered melons in her hands for emphasis. “My BIG tits.”

All this time she did not crack a smile even once. That meant trouble.

“Say it or I’ll tell Mom,” she hissed.

“Tell Mom what?”

“That you like to look up my skirt under the table, and you drop your fork on purpose so you can.” Her beautiful face showed mock anger. “Oh, and I’ll also tell Mom I found your CUM stains in one of my BRAS!”

Jesus, I thought, how could I have been so careless as to leave a stain?

“In one of my BIG bras.” She stepped closer, thrusting out her massive breasts while looking me straight in the eye.

Gaining some composure I said, “Lisa I’m sorry, I.”

“Never mind ‘sorry,’ just admit it, Tom: YOU get extremely aroused by your own sister!”

“I.”

“SAY IT!”

Swallowing a dry lump in my throat knowing I wasn’t getting out of this without giving her what she wanted, “I get extremely aroused by own sister.”

Smiling triumphantly Lisa said, “And?”

“And I’m madly in love your huge boobs,” I said truthfully. Then I added, “You’re the hottest girl in school Lisa.”

She smiled prettily, seeming satisfied. “There, that wasn’t so bad, was it baby brother?” She caressed her giant mounds. “I’m glad you like me.” She reached out and put her slender hand on the obscenely bulging crotch of my jeans. “But don’t jerk off with my bras anymore. Mom will find out.” She removed her hand from the front of my pants and drew herself up on tiptoes to give me a peck on the cheek. This kiss would’ve been wonderful in its own right, but it also caused her big F-cup breasts to press into my chest before she stepped away. I was in heaven.

Lisa turned away and pranced off toward her bedroom, giving me an excellent view of her luscious, heart shaped, panty covered ass. “Mom and Dad will be home soon. I’d better put some pants on.”

Needless to say that night I jerked off furiously thinking about my gorgeous stacked sister and what had transpired that afternoon.

The first time things went beyond just teasing, it was a week after my 15th birthday and Lisa was 17. Our parents were away for the weekend and we decided to rent a couple movies. (For my beautiful, popular sister to stay in on a Saturday night was unusual; I knew something was up.)

As soon as we got back from the video store, she changed into something more “comfortable.” This consisted of a tank top, a schoolgirl kilt skirt that was so short it barely covered her panties in back, and thigh high stockings. By the way her massive jugs moved beneath her shirt I could tell she’d removed her bra as well. When she saw my reaction to her attire she smirked and said, “It’s no fun watching a movie on the couch with my little bro if I’m not giving him a hard-on.”

When she put the tape in the VCR she took her time about it, bending over more than necessary. Her short pleated skirt rode up and gave me a marvellous view of her perfect ass in white satin panties.

She looked over her shoulder at me and asked, “Enjoying the view sweetie?”

“I don’t know what you mean, Lisa,” I feigned, playing the game. She smiled and blew me a kiss.

“You’re right of course Tom. Silly me. You’re only interested in my great, big, BOOBS!” My sister flopped down on the couch next to me, all tits and ass and long sexy legs. But mostly tits.

As the movie played on, my big sister began to snuggle up to me. Her huge breasts were now pressed into me. The urge to reach out and fondle her incredible melons was excruciating. Something had to give. Fortunately, it did: “Do you want to touch them, Tom?” she asked looking up from my shoulder where she’d been resting her pretty head.

I paused tactfully, not wanting to blow this opportunity, then: “You know I do, but I don’t want to do anything that’s wrong, or that would hurt you in any way.

She put her head back on my shoulder and replied, “You’re sweet little brother. You always were.” Then she took my hand in hers and placed it on her left breast. It was firm and wonderful. I marvelled at the size of my sister’s tit in my hand.

“They’re big aren’t they?” she breathed.

“Yes.”

Glancing down at my lap she said, “Well you’re not exactly small yourself, baby brother.” It was true. The erection in my pants at this point had reached heroic proportions, no doubt at its full 8 inches and maybe more.

I moved my hand away from Lisa’s huge chest. I wanted to kiss her so badly. My own sister! I did move to kiss her. She did not pull away. Our kiss lasted a long time.

That is how it began, making out with my sister. We did this whenever we had the house to ourselves. Sometimes she would take my hands and put them on her big boobs or on her butt or thigh. Sometimes she would stop me when I tried this on my own. I didn’t mind; things had already gone farther than my horny teenage dreams had ever imagined they would – with my own sister. My wonderful, huge breasted sister.

Part 2

“Tom, do you know where my new bra has gone, by any chance?” My older sister Lisa hollered from upstairs. Our parents weren’t home (thank God) and she was teasing me again: “The rose colored one. The one that’s a G-cup. Have you had it by any chance?”

A G-cup. Oh jeez, her boobs haven’t stopped growing, I thought, feeling my cock getting hard in my pants. No, I hadn’t seen that particular bra.

Lisa bounced down the stairs wearing nothing but a baggy sweatshirt and panties. But even the oversized sweatshirt didn’t begin to hide her immense breasts. Last time I’d looked at the tag on one of her bras it said 34F. But now G-cup? Now that I thought of it, her tits were looking bigger than ever.

“Well, have you seen it?” she asked.

“No Sis.”

“You haven’t been exploring my underwear drawer again little brother?” She smiled when she said this, walking up to me, her chest preceding her by what seemed like a foot.

“No Lisa.” I was embarrassed yet very aroused; I never tired of my big sister’s teasing games. “We agreed I wasn’t to jerk off with your (big) bras anymore, ” I said sheepishly, “Mom might find out when she does the laundry.”

“Good boy Tom.” She reached up and tousled my hair, her big tits seeming to expand beneath her sweatshirt.

God, I thought, she’s incredible; those jugs!

“How ’bout a hug for your sister?” Before I could respond her arms wrapped around me and pulled me close. Her humungous, melon-like breasts pressed into my chest.

“And a kiss?” she asked. But again, before I had a moment for that question to even sink in, she was planting one on me. “Mmmm,” she purred. She pulled away. “I gotta scoot. Date with Rick tonight.” My heart sank. I was hoping I’d have her to myself that night; are parents would be out. Our incestuous relationship hadn’t progressed beyond kissing and light petting but these times with my 17-year-old sister thrilled me more than anything ever had in all my 15 years.

Later that evening. “Tom, do you think my butt looks good in this skirt?” Lisa posed suggestively in front of me, presenting her perfect heart-shaped ass to me encased in a black spandex mini skirt.

“Your butt looks incredible in that skirt Sis,” I told her truthfully.

“You’re not just saying that to be nice, ’cause I’m you’re sister?” She mock pouted.

Then she looked at my crotch and smirked. “No, I guess you really do like the way I look in this skirt, judging by the tent your big dick is making in your pants!” Then she looked thoughtful. “Hmmm, some day we’re going to have to do something with what you’ve got there, Tom.” She kept staring at my big bulge and said, “My not so little brother.”

Lisa glanced up at the clock. “And I think that day is today.” She kneeled down. Her beautiful face was level with my big bulge. “Hmmm. I’ve wanted to see your big cock for a long time, Tom.” She unzipped my jeans and licked my erection through my briefs. Then rather unceremoniously she yanked my underwear and jeans down to my knees. My 8- incher sprang free and almost slapped her in the face.

“Oh my God bro, it’s HUGE.”

My older sister wrapped her luscious lips around my thick cock, and then she withdrew, taking in the site of what was in front of her.

“And YOU’VE GOT THE BIGGEST BALLS I’VE EVER SEEN!” She hefted them in her slender hands.

Then my gorgeous 17-year-old big sister got down the business of giving me a blowjob. My first blowjob. I watched her pretty mane bob up and down on my fat cock. The sensation, the pleasure, was unlike anything I’d yet experienced in my life to that point. I gently took her head in my hands as she sucked and licked.

I’d like to tell you this went on for a long time but it didn’t. The excitement was too much. I was 15 after all and made of nothing but raging hormones. My orgasm exploded in my Lisa’s succulent sucking mouth. I came what seemed like gallons yet she did not pull away. (She told me later she didn’t want to get cum on her clothes.)

I stood there in stunned silence, my pants around my knees, my beautiful, enormously stacked sister kneeling before me, licking my cum off her full, pouty lips.

“Well that was fun bro,” she said. “I’d better go finish getting ready for my date.” She stood up and straightened her silky blouse over her big tits. “And brush my teeth. We don’t want Rick tasting my brothers cock when he kisses me.”
