My Sister is Embarassed about her Gigantic Breasts

Every Summer for our mom's birthday, my twin sister Nichole and I go into town to find a gift to get her from both of us.

The summer after we graduated high school, we found ourselves at Barnes and Noble in the afternoon the day before Mom's birthday. It was a family tradition not to get things done very long before the deadline. Nichole and I had both turned eighteen a few months earlier.

"Is Mom still into those self-help books?" I asked Nichole absently. She shrugged and we wandered over to another section. Mom was an avid reader, so bookstores were usually a good bet.

We wandered slowly through the store, not seeing anything that really caught our eye. Eventually we wound up at the magazine rack at the back of the store.

"Oh, God. Shit," I heard my sister hiss under her breath suddenly. I saw her look over at some guy and then she pressed her body up against mine. And when I say that, I mean she *really* pressed against me in a way she had never done before.

"There's this guy I used to talk to, like, *right* over there. Pretend like we're dating," Nichole whispered into my ear.

"But, we go to the same-" I began to protest, but Nichole interrupted me:

"He's not from *around* here," She explained. All right then. The guy woudln't know that I'm Nichole's brother.

Nichole put her hand around my waist. To help complete the illusion, I placed my arm around her shoulder. And just in case the guy was watching us, I turned and kissed my twin sister on the top of her head several times. She looked up at me and unexpectedly kissed me briefly on the lips. I'd say the illusion was complete at this point.

Nichole had relatively large breasts, and they were pressed firmly against my side at that moment. I didn't think much of it, since she's my sister, but I did notice it. We stayed close as we continued to peruse the magazine rack.

We eventually landed on a World War 2 book for Mom's birthday. It's not the kind of thing you'd expect a lady like our mom to be into, but she coudln't get enough of that stuff. Weird.

I kept thinking of our brief kiss. It felt weirdly natural, even though we've never been a "kiss-on-the-lips" family.

That night, Nichole came to my room to thank me for helping her with the show we had to put on for her ex-dude's benefit. I didn't want to know too much about this *ex-dude,* so I didn't pry.

"Thanks for playing along, Danny. I think it worked. Sorry you had to feel your sister's *nasty gigantic breasts* up close and personal," she told me as she walked into my bedroom. I paused my video game. "But it really worked," she repeated.

I didn't want to be weird or anything, but I didn't want my sister to feel badly about herself either. And just because she has huge tits? Nasty? What was she talking about?

"Nichole, if you weren't my sister, I would've been into it," I said carefully.

"Eh," she sighed. "It's whatevz."

"Dude," I said to her. "Guys like big boobs. Doy."

Nichole just rolled her eyes and looked away. What the heck?

"Is there something *wrong* with them? Are they *green?"* I teased her.

"No!" She giggled. I was glad to hear her laugh.

"Are they *lumpy?"* I asked sarcastically. She shook her head.

"All right, then you're probably good," I said nonchalantly and turned back to my video game and unpaused.

"I guess I could *show* you," Nichole sighed. "It's nothing you haven't technically seen before," she added.

"Uh, well, last time I saw you topless, uh... I don't think your boobs existed yet," I replied, trying to keep my voice even and pretending to be paying close attention to my game.

"Whatever. I'm just gonna show you so you know what I mean," Nichole said.

"Sharing is caring," I replied. Nichole smiled and rolled her eyes as she quickly pulled her shirt off over her head. She was still wearing her bra.

"Looks fine to me," I said casually.

"Hang on," she said while struggling to unclasp her bra in the back. Finally she got it, and then she pulled it off from the front. She temporarily yanked both of her massive breasts up in the process, and they made 2 distinct loud slaps when they landed on Nichole's upper torso.

Nichole stood topless in front of me. At first she covered her nipples instinctually, but then she put her hands on her hips and looked up and away from me. She looked pretty embarassed.

"See?" she asked, still looking at the ceiling.

I saw a few things that I thought may have been what she was bothered by, but to me, all of those things were either no problem, or they looked awesome to me.

Her breasts were truly massive. Nichole was no where near the biggest girl I had ever seen, but she definitely had the biggest tits. It's possible that just the sheer size of them, especially in contrast with the rest of her relatively normal-sized body, was one of the things she was self-conscious about.

They were so tremendous that they took up a significant amount of real-estate on her chest and torso. They didn't look saggy, but they went most of the way down to her belly button. Very much of her upper torso was covered by her tits. It must have been really hot and sweaty in the space between.

Nichole's boobs were also extremely pale, as if they almost never saw natural light. Even underneath her wide nipples, a faint network of blue-green veins could be seen underneath her skin.

Nichole's nipples were wide, and I could barely tell where they ended or began.

Like I said, none of this bothered me at all. In fact, it did the exact opposite. I'm ashamed to admit that seeing my sister's tits had affected me in my lower region; and it had affected me very much. If I didn't adjust, it would soon be far too obvious. It's a good thing I was still wearing actual shorts, and not just boxers or pajamas, like I usually wore at home.

"Nichole," I said, diverting my eyes from her chest up to her confused face, "you've got nothing to worry about."

\_\_\_\_\_

"Yeah," she said disappointedly, "whatever." She began to put her bra back on.

"I'm not just saying it, Nick..." I told her truthfully, but she just continued getting dressed. "What, you don't believe me?" I asked.

She scoffed. "I can't even believe I just *did* that." Her face was scrunched up and she sounded like she was about to cry.

My heart sort of broke. I had always thought my twin sister was pretty good looking. At least as good looking as me, since we're basically the same person, being twins and all. I was a little more athletic than Nichole, but we still looked very similar, and I had never been attracted to fit women anyway.

And I won't lie: I've always been a little narcisistic about my appearance. I'm a pretty good-looking guy; and since my sister and I are actually *identical* twins, that extends to her too. And by the way, just in case you didn't know, you can be identical twins with someone of the other gender. It's less common, but it still happens.

If she didn't believe me, maybe there was something else I could try. I felt bad for her, but I was still fully hard from the view I had just had.

"If you *really* don't believe me, I can prove it to you, Nick," I said seriously and a little forcefully. It was uncharacteristic of me to be this forward with her, and she sort of froze for a split second as she was putting her shirt back on.

"How?" she asked as she slowly began to lower her shirt back down.

I motioned with my eyes down to my crotch. My penis wasn't fully hard, but that was only because it was facing down and pushing, very visibly, against the front of my shorts, trying to face straight up and achieve its ultimate form. My sister followed my gaze downward.

"What is *that?"* she asked. She sounded grossed out, but she also sounded like she was *trying* to sound grossed out.

*"That,"* I told her, "is a boner. Aintcha ever seen one?"

"Uhm, yeah," she replied sarcastically. "I've seen *thousands* of them." I laughed through my nose at the word *thousands.* Her eyes didn't leave my groin, which only made my erection strain harder against the front of my shorts.

"Yeah, well," I said as I adjusted myself, "It's kinda involuntary. Just happens when I see something I like," I said as nonchalantly as I could.

Nichole blushed really hard when I said that, and she dropped her shirt again, this time completely. However, she still had her bra on.

"Can I see them again?" I asked, and my voice was filled with shyness and embarassment and hopefulness.

"Can I see too?" she asked, still looking at me, but not into my eyes.

I told her she could, and I slowly began to unbutton my shorts.

\_\_\_\_\_

Nichole undid her bra while I unzipped and pulled myself out of the hole in front of my boxer shorts. I left my shorts on as much as I could. I slouched down a little in my chair and held my fully erect penis up for my sister to see.

Nichole seemed distracted by what she was seeing; she still hadn't managed to remove her bra yet.

"Hey, let's get this show on the road," I teased her while making a circular motion with my left hand.

"Yeah, yeah, I'm goin'," Nichole replied. She finally pulled her bra off and her tits slapped loudly against her stomach.

Nichole used her arms to push her enormous breasts together. Without really meaning to, I began to slowly stroke myself in front of her. Nichole's face was bright red. She smiled and shifted her feet, causing her breasts to jiggle just a little bit. I continued stroking.

"Can I get a closer look?" my sister asked me.

"Uh-huh," I replied, still stroking myself.

Nichole kneeled down and slowly inched towards me on her knees. She smiled wider as she drew closer.

"Can I try?" she asked innocently.

"Try what?" I replied, not comprehending, continuing to stroke.

"Stroking your cock?" She replied. Holy shit.

"I guess so," I said while trying to keep my voice even. I removed my hand from myself, and my penis pointed straight up at me.

Nichole slowly reached out and wrapped her fingers around the base of my shaft. She seemed to gently close her hand more tightly around me and then release. She did this several times.

"You're so hard," she said to herself, gazing intently at the head of my penis.

"I told you, it's just because I like what I see, duh," I complimented and teased her. She blushed really hard.

"I wanna take your pants all the way off," she told me. I lifted my butt up and she pulled my pants and underwear all the way off of me.

"I love you so much, Nick," I told her as she lifted her breasts and plopped them down in my lap with my penis in between them. Her pink nipples pointed directly up at me.

"I love you more," Nichole replied just before pushing a big white glob of spit out of her mouth and onto the tip of my penis. As it dripped and slid down the sides of my shaft, she gathered more spit in her mouth and dropped it on the tip of my penis again. She reached around her breasts and used her hand to rub her slimy spit all over the shaft and head of my penis.

I watched her in near disbelief as she then positioned my penis in between her tits and started sliding them up and down my shaft, plopping noisily in my lap each time they came down. The sound became wetter and wetter as she worked.

"Does it feel good?" she whispered, and I could barely hear her over the moist sound of her jerking me off with her chest. I told her it felt amazing, and I told her I loved her again.

Nichole's face and chest became read and sweaty as she continued to work on me for several more minutes. I loved seeing how hard she was working to make her brother feel good. Eventually I could tell that I was getting closer.

"Nick," I huffed, "Nick, I think I'm gonna cum soon." She didn't stop.

"So cum," she grinned at me. She was already going pretty fast, but now she started going harder too, really slamming her tits down into my lap each time. She was going to finish me in between her tits.

"Nick... I'm cumming... I'm cumming..." I breathed to my sister as I began to ejaculate between her tits. Every once in a while the tip of my penis would emerge at the top of her breasts just in time for a spurt of cum to hit Nichole in the neck and under her chin. She didn't seem to mind having her brother's cum so close to her face.

Nichole smiled really wide when I was cumming. She looked so proud of herself.

Soon I was finished, but Nichole didn't want to stop. She kept stroking me with her tits and the sensitivity drove me crazy, soon I had to push her off of me.

"Too sensitive, dude!" I told her.

"What? Really?" She asked. I told her that yeah, duh, after a guy cums his dick is really sensitive for a while. She acted like she'd had no idea.

Nichole was still on her knees in front of me. She leaned back, using her left hand behind her back to steady herself on the floor. Her breasts spread apart, and I could see how wet with semen and spit her chest was. Sperm was beginning to drip down the center of her chest and was approaching her belly button.

"God, what a mess," Nichole said nonchalantly as she used her free hand to scoop my sperm up from her belly and spread it up towards her chest. Then she adjusted her seating position to free up her left hand, now sitting Indian-style on the floor in front of me. Then she used both hands to rub my semen into both of her tits. I noticed her paying extra attention to her nipples whenever her fingers came across them. I noticed her nipples start to get hard. Soon both of her tits were shining evenly with semen and spit.

"Well, I guess these things are good for *something,"* Nichole remarked, looking down at her breasts. I leaned forward and playfully slapped her left tit.

"They're fucking *great*," I told her lovingly.
